This study guide should help you understand what to expect on the exam and includes a summary of the topics the exam might cover and links to additional resources. The information and materials in this document should help you focus your studies as you prepare for the exam.

Updates to the exam

Our exams are updated periodically to reflect skills that are required to perform a role. We have included two versions of the Skills Measured objectives depending on when you are taking the exam.

We always update the English language version of the exam first. Some exams are localized into other languages, and those are updated approximately eight weeks after the English version is updated. While Microsoft makes every effort to update localized versions as noted, there may be times when the localized versions of an exam are not updated on this schedule. Other available languages are listed in the Schedule Exam section of the Exam Details webpage. If the exam isn't available in your preferred language, you can request an additional 30 minutes to complete the exam.

The bullets that follow each of the skills measured are intended to illustrate how we are assessing that skill. Related topics may be covered in the exam.

Most questions cover features that are general availability (GA). The exam may contain questions on Preview features if those features are commonly used.

How I passed the Azure AZ-204 Certification Exam

In this article i share my experience and how i passed the microsoft azure az-204: developing solutions for microsoft azure.

Hey everyone! If you're prepping for the Azure AZ-204 Developer exam, you're in the right place. I recently passed, so I want to share my experience and the strategies that worked for me.

I was excited and a little nervous heading to the test center. The exam definitely challenged me, but walking out with a passing score of 737 felt amazing! I know I barely passed, as 700 is required passing score and also I barely finished in time, so managing those minutes is essential!

How Did I Prepare?

The big question, right? Here's the thing: I didn't use any traditional courses. Instead, I've been building projects on Azure for a while now, and that hands-on experience was my main study method. Here's what I focused on:

Microsoft Learn Challenges: During the Microsoft Build Cloud Skills Challenge, I got a free exam voucher by completing the Microsoft Build: Cloud Development Challenge. It covered some of the AZ-204 modules.

Microsoft Learn Modules: Outside of the challenge, I went through all the AZ-204 modules on Microsoft Learn. See them here.

Hands-On Projects: This was the MOST important part! Over time, I've built projects on Azure that used the skills on the exam guide. Check out tools like Azure Functions, container apps, and storage accounts.

Important Extras

The AZ-204 Exam Guide: Find it on the Microsoft website . Be super familiar with the skills you'll be tested on.

Following are the domains you will be tested on with weightage:

Develop Azure compute solutions (25–30%)

Develop for Azure storage (15–20%)

Implement Azure security (20–25%)

Monitor, troubleshoot, and optimize Azure solutions (15–20%)

Connect to and consume Azure services and third-party services (15–20%)

Open Book Option: Azure now lets you use Microsoft Learn during the exam! I found this useful, but be careful not to spend too much time searching for every answer.

Build, build, build! Nothing replaces hands-on experience.

Know the exam guide so you're building the right kinds of projects.

Manage your time during the exam.

Not Just About the Badge

I'm proud to now be seven-times Azure certified, but it's the knowledge that matters most. I love challenging myself to learn through real-world problem-solving!

It's totally possible to pass the AZ-204 if you're focused on practical learning. If you have the time to invest in building projects, I believe you can do it!

Let me know your thoughts or questions in the comments!

Domain : Monitor, troubleshoot, and optimize Azure solutions

Q18 : A developer needs to enable Application Insights Profiler for the Azure Web App. Which of the following feature is required to enable Application Insights Profiler for a Web App?

A. CORS configuration B. Always On setting C. Enable Identity D. Enable Custom domains

The requirement is to enable Application Insights Profiler for a web app which captures the data automatically at scale without negatively affecting to end-user and widely used for monitoring purpose. and the given options are

A. CORS configuration     Cross-origin resource sharing (CORS) defines a way for client web applications that are loaded in one domain to          interact with resources     Hence this is not going to help us to enable Application Insights Profiler B. Always On setting     If a web app sits idle for too long, the system unloads the website, and when traffic returns, the system needs to        load the Web App which causes longer response time and higher utilization of resources. By enabling the ‘Always          On’ setting (available for Standard tier websites), keeps the Web App up and running, which translates to higher          availability and faster response times across the board.     Since the requirement is to enable ‘Application Insights Profiler’ for a web App, Enabling ‘Always On’ is the correct        prerequisite.     Hence this is the correct answer. We recommend you find detail at https://docs.microsoft.com/en-us/azure/azure-        monitor/app/profiler C. Enable Identity      identity is part of Azure Active Directory hence not related to Application Insights Profiler D. Enable Custom domains      Enable Custom Domain is a feature to access any Azure URI by different or customized URI. Hence this is not               related to enabling Application Insights Profiler

We have to enable the “Always On” setting.

For more information on enabling Application Insights for the Azure Web App, please visit the below URL: https://docs.microsoft.com/en-us/azure/azure-monitor/app/profiler

Q19 : A team has to integrate various modules of an application with the Azure Event Grid service. They have to filter events which are sent to the various application endpoints. The requirements for the type of messages that need to be received by the different endpoints are given below

Which of the following would you use as a filter option for messages that need to be sent to EndpointC?

A. Subject begins with or ends with B. Advanced fields and operators C. ResourceTypes D. EventTypes

Here since we need a more advanced scenario and check for the data field values, we have to choose the “Advanced fields and operators” filter option

For more information on event filtering in Azure Event Grid, one can go to the below URL: https://docs.microsoft.com/en-us/azure/event-grid/event-filtering

Q20 : You are developing an Azure Function. This function will be using the Azure Blob storage trigger. You have to ensure the Function is triggered whenever .png files are added to a container named data. You decide to add the following filter in the function.json file “path”: “data/png” Does this filter criteria meet the requirement?

This is the wrong structure of the filter that needs to be used for this scenario

The right filter structure is as follows

“path”: “data/{name}.png”

For more information on the blob trigger, please refer to the following URL: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=csharp

A. getBody B. setBody C. getDocument(); D. getContext(); E. createDocument F. newDocument

A. Resource B. Condition C. Check D. Version

You would add a Condition control to check the details of the event.

For more information on the actual use case scenario example, please refer to the following URL: https://docs.microsoft.com/en-us/azure/event-grid/monitor-virtual-machine-changes-event-grid-logic-app

Q23 : You have to develop an ASP.Net application. The application is an on-demand video streaming service. The application would be hosted on an Azure Web App service. To facilitate the delivery of content, you decide to use the Azure Content Delivery Network service. An example of a URL which users would use for viewing a video is given below

• http://www.whizlab.com/videos/video1.mp4?quality=h

All of the video content must expire from the cache after an hour. The videos of varying quality must be delivered from the closest regional point of presence. You have to implement the right caching rules. Which of the following would you choose as the cache expiration duration?

A. 1 second B. 1 minute C. 1 hour D. 1 day

Since the requirement mentions that the cache content needs to expire after an hour, we have to choose the setting of 1 hour.

Since the time frame is clearly mentioned in the requirement, all other options are incorrect.

For more information on Azure CDN cache settings, please refer to the following URL: https://docs.microsoft.com/en-us/azure/cdn/cdn-caching-rules

A. instance create B. container create C. instance logs D. container logs

To pull the container logs, we have to use the az container logs command

Case Study : A company currently has a social networking site in place. The content for all messages is first processed before being posted on the social networking site. The content for the messages is stored Azure Blob storage. Application Services The following services are used as part of the processing system

• ContentUploader – This is used to pick up the messages from Azure Blob storage.
• ContentProcessor – This service has been designed by Data scientists. This service processes the messages to check for any potentially offensive or unwanted content.

The Content Uploader service makes use of Azure Functions. The Content Processor service is designed as a container and is published using the Azure Container Service. The image for the processor service is stored in Azure container registry named ContentRegistry The Content Processor service would process the messages and output a number indicating a threshold on whether the message could be posted or not. For each message that can’t be posted, an employee of the company needs to perform a manual review of the message content. Manual Review For the manual review, the company employees need to first log into the ContentProcessor service by using their Azure AD credentials. The employees need to have the ContentAdmin role for a successful login attempt. When the employee successfully logs in and performs a manual review of a message, an email needs to be sent to the appropriate stakeholders. End user agreement For all users that post messages to the platform, they have to agree to an end user agreement. This agreement would state that all messages might have to undergo a manual review by company employees. There would be a huge volume for the end user agreements, around a million per hour. Security Requirements

• All data transmitted between services must be encrypted at rest and in transit
• The storage account keys must be available only in memory and must not available anywhere else in the system
• All container network traffic must be restricted to an Azure virtual network.
• When there is a newer version of the application, an automated process must be initiated to ensure the newer version is first verified before it is deployed to production.

Q25 : You have to view the diagnostic information about the container during the startup process. Which of the following command would you execute to get the relevant information?

A. az web config B. az container attach C. az logs D. az docker logs

We can use the az container attach command for this purpose.

This is also given in the Microsoft documentation

For more information on getting container instance logs, please refer to the following URL: https://docs.microsoft.com/en-us/azure/container-instances/container-instances-get-logs

Domain : Connect to and consume Azure services and third-party services  

Q26:You are developing an application to publish events in batches using the Azure Event Hubs library for .Net. The events need not be published immediately to publish large batches efficiently. Which API class should you recommend?

A. EventHubProducerClient

B. EventHubConsumerClient

C. EventHubBufferedProducerClient

D. EventProcesserCheckpoint

Option C is correct:

The EventHubBufferedProducerClient does not publish immediately, instead it uses a deferred model where events are collected into a buffer so that they may be efficiently batched and published when the batch is full or the MaximumWaitTime has elapsed with no new events enqueued.

Option A is incorrect:

The EventHubProducerClient publishes immediately, ensuring a deterministic outcome for each send operation, though requires that callers own the responsibility of building and managing batches. When there is no need to publish the events immediately, it is recommended to consider using the EventHubBufferedProducerClient, which takes responsibility for building and managing batches to reduce the complexity of doing so in application code.

Option B is incorrect:

The EventHubConsumerClient class is used to consume events from an Event Hub.

Option D  is incorrect:

EventProcesserCheckpoint contains the information to reflect the state of event processing for a given Event Hub partition.

For more information on Azure event hub, please refer to the following URL:

https://learn.microsoft.com/en-us/dotnet/api/azure.messaging.eventhubs.producer.eventhubbufferedproducerclient?view=azure-dotnet

Domain: Connect to and consume Azure services and third-party services  

Q27: You are working on an image library application. When the author uploads a new image you need to save the raw image and convert the image into various formats and save it to the database. You also should be able to view failed APIs logs and should be able to retry them.

Which of the below solutions is best recommended?

A. Create the azure service bus topics “raw-image-topic”, “image-processer-topic”.

Create subscriptions for each of these topics. 

Create two APIs which can subscribe to each of these subscriptions.

B. Create the azure service bus topic called “image-topic” and create two subscriptions namely “ raw-image-sub ” and “ image-processer-sub ”.

When the publisher publishes messages on the topic, each of the subscribers will receive the message to consume it independently.

C. Create two azure function APIs namely “AfSaveRawImage” and “AfFormatImage”.

Call these APIs from the client side independently passing the raw image file as payload.

D. Create two azure service bus queues “raw-image-queue” and “format-image-queue” and create APIs for each of these queues to consume the message.

Option B is correct:

Azure service topics and subscriptions provide a one-to-many form of communication in a publish and subscribe pattern. It’s useful for scaling to large numbers of recipients. 

Each published message is made available to raw-image-sub and image-processer-sub registered with the image-topic . A publisher sends a message to the  image-topic and the subscriber’s raw-image-sub and image-processer-sub will receive a copy of the message. 

And raw-image-sub and image-processer-sub will be executed without having a dependency on one another. When any of the registered subscribers failed to complete the execution after the default number of retries, those messages will be forwarded to the dead letter queue where you can view the failed messages and be able to retry them.

When you want to perform multiple actions(i.e saving the raw image file and converting the image to multiple formats)  on the same data, it is recommended to use a single topic with multiple subscribers. Because you can easily add more subscribers for more actions.

Option C is incorrect because it does not comply with the given requirements. For stand-alone APIs, it is not straightforward to be able to view failed APIs and retry them.

Option D is incorrect because When you want to perform multiple actions (i.e saving the raw image file and converting the image to multiple formats) on the same data, it is recommended to use a single topic with multiple subscribers. So that each subscriber can be executed for each action.

A queue allows the processing of a message by a single consumer.

Domain: Monitor, troubleshoot, and optimize Azure solutions  

Q28:You are developing a solution which involves Azure Redis cache.There are no keys with the TTL value set but still, you need to remove the key if the system goes under memory pressure. What eviction policy for Azure Cache for Redis would you recommend?

A. allkeys-lru

B. volatile-lfu

C. noeviction

D. volatile-random

Option A is correct:

allkeys-lru policy keeps most recently used keys; removes least recently used (LRU) keys

If no keys have a TTL value, then the system won’t evict any keys. If you want the system to allow any key to be evicted due to memory pressure, then you may want to consider the allkeys-lru policy. 

Volatile-flu removes the least frequently used keys with the expire field set to true.

Option C is incorrect:

In the Noeviction policy, new values aren’t saved when the memory limit is reached. When a database uses replication, this applies to the primary database.

Option D is incorrect:

  Volatile-random policy randomly removes keys with expire field set to true .

For more information on Configuring cache and expiration policies for Azure Cache for Redis, please refer to the following URL:

https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-best-practices-memory-management#eviction-policy

Q29:You are developing an application that uses Azure Cosmos DB to save the data. In the current implementation, you have found performance issues due to hot partitioning that did not allow Azure Cosmos DB to scale very well.Which of the following resulted in hot partition?

A. Querying over the non-partition key

B. Querying over the single partition key

C. Not defining any indexing policy

D. Creating partition key design that distributes requests unevenly

Option D is correct:

Hot Partitions occur due to the imbalance of logical partitions, where some logical partitions are very large and some are very small which does not allow Azure Cosmos DB to scale.

Instead, create a partition key that will give uniform distribution of storage and throughput.

Querying over the non-partition key results in the cross-partition query. (which queries over the entire cluster). This does not result in Hot Partition.

Querying over the partition key results in the single partition query, i.e Azure Cosmos DB can efficiently fetch the results as it knows from which physical partition it needs to fetch the data.

In Azure Cosmos DB, every container has an indexing policy that dictates how the container’s items should be indexed. The default indexing policy for newly created containers indexes every property of each and every item.

For more information on partitioning schemes and partition keys, please refer to the following URL:

https://learn.microsoft.com/en-us/azure/cosmos-db/partitioning-overview#physical-partitions

Domain: Develop for Azure storage

Q30: You are developing an application that uses Azure Cosmos DB to save the data. All the documents in a container should be auto-deleted after 24 hours.Which approach would you best recommend to achieve the requirement?

A. Set the “TTL” property for each document in the container.

B. Set the ‘ TTL’ property from ContainerProperties class at the container creation time.

C. Set the DefaultTimeToLive property from ContainerProperties class at the container creation time.

D. Create a timer trigger that runs every 24 hours and deletes the documents from the container.

To set the time to live on a container, you need to provide a non-zero positive number that indicates the time period in seconds. 

You can set time to live on a container or an item within the container using the DefaultTimeToLive propert y from ContainerProperties class.

Option A is incorrect because it is not recommended for the current requirements as any change in the item, ‘TTL’ value will override every container DefaultTimeToLive property.

Option B is incorrect as  ContainerProperties class does not have a property named ‘TTL’

Option D is incorrect because it creates more time and complexity. We can easily achieve this using the DefaultTimeToLive property from ContainerProperties class.

Hope our efforts in this article have proved helpful to you and now you feel more confident and prepared after learning the AZ-204 exam questions and answers. To strengthen your preparation a level up, go through the elaborate and descriptive Practice Tests in Whizlab’s official webpage. AZ-204 practice tests looks very similar to the actual exam which boosts your confidence before attempting the direct exam.

Mastering the AZ-204 Exam - A Comprehensive Guide to Azure Certification Preparation

Earning the AZ-204: Developing Solutions for Microsoft Azure certification can seem daunting. This certification not only validates your skills and knowledge in Azure but also serves as a stepping stone towards the DevOps Engineer Expert certification.

This blog post aims to help you understand the certification process and provide you with a roadmap to success. From understanding the exam content to leveraging community resources, from gaining hands-on experience to acing practice assessments, this article will walk you through each step. Whether you are a seasoned Azure professional or a fairly newcomer to Azure, this guide will equip you with the tools and insights you need to confidently tackle the AZ-204 exam.

Preparing for the Exam

Before you even start preparing for the exam, it’s crucial to familiarize yourself with the exam’s content and the required passing score. All this information is readily available on the Certification Exam Page . The exam measures your skills in the following areas:

Microsoft Learning Paths

The Certification Exam Page provides links to all the articles that make up Microsoft’s Learning Path for the AZ-204 certification. This Learning Path is divided into twelve distinct areas, each containing one to four modules. Each area focuses on a specific technology, such as Azure Functions or CosmosDB.

For convenience and easy access, especially during commutes or gym sessions, I’ve compiled all the Learning Paths into a Word document. However, be aware that this document spans nearly 300 pages. Therefore, navigating through all the Learning Paths will require a considerable amount of time.

Azure Documentation

Microsoft provides an extensive Azure Documentation that encompasses a thorough examination of each Azure service. This resource not only offers valuable recommendations for service implementation and best practices, but it also includes instructive tutorials and quick-start samples to help you get started with the services you are interested in.

Community-Provided Resources

In addition to the resources provided by Microsoft, the community also offers a wealth of valuable materials. If you are a fan of video content, John Savill’s Youtube Channel comes highly recommended. He provides a variety of videos to help you prepare for several exams, as well as in-depth explorations of various Azure-related topics.

Google is always a reliable source of information, but Reddit can also be incredibly helpful. For general Azure and certification topics, check out the Azure Subreddit or the Azure Certification Subreddit . If you are interested in delving into a specific topic, such as CosmosDB, there’s likely a dedicated Subreddit for that as well.

Dive into Azure

Regardless of how much you study about Azure, nothing can substitute the value of practical, hands-on experience. The exam will pose detailed questions about service configuration and what to watch out for when using them. This level of understanding can only be achieved through consistent interaction with all the services.

If your work doesn’t provide an opportunity to engage with the services covered in the exam, consider creating a free Azure account and implementing your own projects. Begin with a modest project, such as a web application running in a container, and gradually expand. Once your container is operational, incorporate a CosmosDB, monitoring, and then an Azure API Management.

Furthermore, allocate some time to explore each pane in the Azure Portal for each service. Ensure you comprehend the function of each pane and how it can be utilized to configure this service or establish connections to other services.

Free Practice Assessment

When you feel prepared for the exam, it’s time to take the complimentary practice assessment available on the Certification Exam Page . Alternatively, you can access the free practice assessment directly .

The assessment comprises 50 questions and may serve as a stern reality check. Typically, my initial scores never exceed 70% (more often in the 50%-60% range), despite having several years of experience with Azure and likely more exposure than the average examinee. Don’t be disheartened by a less-than-stellar result. The assessment is a tool to highlight the areas where you need to invest more time and to give you a glimpse of the exam’s question format. Moreover, Microsoft provides an explanation for each question, clarifying why the correct answer is superior to the other options.

Feel free to retake the assessment as many times as necessary until you gain confidence.

MeasureUp is the officially endorsed test platform by Microsoft. The AZ-204 practice exam on this platform features 127 test questions, mirroring the actual certification exam’s format with case studies, single-choice, multiple-choice, and drag-and-drop questions.

Compared to other resources mentioned here, the practice tests on MeasureUp are on the pricier side, with costs ranging from 99€ for 30-day access to 119€ for a one-year subscription or downloadable version. Do often have sales bringing down the price by 30-50% though.

The website’s user experience may leave something to be desired. For instance, locating the correct place to take the practice exam can be a challenge, the website’s speed is often slow, and you may occasionally find yourself logged out while taking a practice test. However, once you start the practice test, the experience is smooth (provided you don’t get logged out). You even have the option to customize the test exam to include random questions, questions you previously answered incorrectly, or questions you haven’t seen in a while.

The difficulty level and format of the practice questions are on the same level as you will encounter in the real exam, making it an excellent preparation tool.

While MeasureUp may be expensive, it’s worth the investment. I strongly recommend utilizing it before taking the exam.

Study Strategies

Study methods vary from person to person. Some individuals prefer video content, others favor reading, and some learn best through hands-on experience.

My advice is to explore all these methods and identify what suits you best. In my case, having prior experience with all the services covered in the exam and then thoroughly studying the Learning Path was sufficient to pass the exam. The MeasureUp practice exam and the free practical assessment were particularly useful in highlighting areas that needed more attention.

Gaining enough hands-on experience is also crucial. My prior experience greatly aided my understanding of the topics when I studied the documentation. I would suggest creating most of the services covered in the exam, experimenting with them, and familiarizing yourself with all the panes of the service in the Azure portal.

Lastly, I highly recommend investing in the MeasureUp practice exams. Not only are they worth the cost, but they also provide insight into the format of the exam questions. Achieving high scores in these practice tests can significantly boost your confidence.

Taking the Exam

You have two options for taking the exam: at an official test center or from the comfort of your home. I’ve experienced both, and while I used to take exams at a test center, I now opt for online tests. Both methods administer the exact same exams, so choose the one that best suits your comfort level.

The exam duration is 120 minutes, but you should allocate approximately 150 minutes to account for the ID verification process and a few survey questions from Microsoft. This provides enough time to review your answers multiple times. In my experience, I was able to complete the exam in about an hour.

The exam contains between 40 and 60 questions, I had 54. To pass, you need to score at least 700 out of 1000. It is important to note that Microsoft employs a dynamic scoring system, meaning that a score of 700 out of 1000 does not equate to 70%.

Upon completion of the exam, your score should be displayed on the screen immediately. If not, expect to receive an email with your test score within the next hour.

After passing the exam, you get the Azure Developer Associate badge.

Taking the Exam at a Test Center

A few years ago, I took a test at a test center, and it wasn’t the most enjoyable experience. Firstly, you have to commute to their location, ensure punctuality, and carry an official ID. Then, you are required to store all your personal items, such as your wallet, phone, and watch, in a locker before being escorted into a computer-filled room to take your exam. My test center had a mouse from the 90s, which was quite challenging to work with. The room was crowded with other test takers, making it somewhat noisy.

However, there’s nothing inherently wrong with taking the exam at a test center, it iss just a matter of personal preference.

Taking the Exam Online

Opting to take the exam from home offers a more convenient alternative. This requires a stable internet connection, a webcam, and a microphone. Note that headphones are not permitted.

The comfort of taking the exam from home is unparalleled for me. Not only does it eliminate the need for travel, but it also allows you to use your own computer, mouse, keyboard, and chair, which you are already used to. The check-in process begins 30 minutes before the scheduled exam time. You will receive a link on your phone, which you will use to take a picture of your ID and yourself, followed by four pictures of your surroundings. You will then be placed in a waiting queue. After a few minutes, a proctor will contact you, either via voice message or chat, and may ask you some questions, such as requesting a view of your desk. Once they initiate the exam, the official test begins.

Upon completion of the exam, your score and performance in each exam area will be immediately displayed.

Difficulty of the Exam

In my experience, the AZ-204 exam was more challenging than the Azure Solutions Architect Expert (AZ-303 and AZ-304) and the Azure DevOps Engineer Expert (AZ-400) exams. I was particularly surprised by some questions that delved into the tiniest details of an Azure service. Also some questions asked for the exact syntax of a PowerShell or Phyton script. Some questions were also poorly worded to the point where I couldn’t understand them. I had a bad feeling that I would fail the exam before I finished it. However, I ended up passing with a score of 787. Although it is my lowest score to date, a pass is still a pass.

During the exam, it is crucial to read the questions carefully. A single word can sometimes alter the answer to a question. If you come across a question that leaves you stumped, take a moment to breathe and try to eliminate incorrect answers. Often, one or two answers are blatantly wrong, leaving you with only two potential answers. If you are still unsure, make an educated guess. There’s no penalty for incorrect answers, so never leave a question unanswered!

The AZ-204: Developing Solutions for Microsoft Azure certification exams demand extensive studying and hands-on experience but are entirely manageable with adequate preparation. This certification also serves as a prerequisite for the DevOps Engineer Expert certification . I initially undertook the AZ-204 solely for the DevOps Expert certification, but I am glad I did because it allowed me to learn several new aspects about Azure.

Geek and lover of all things tech related, az-204 exam study guide (developing solutions for microsoft azure).

The AZ-204 (Developing Solutions for Microsoft Azure) exam is tailored to Microsoft developers working on the Azure cloud platform.

Having recently passed the AZ-204 exam I wanted to share my thoughts and insights in this AZ-204 Exam Study Guide to help you pass the exam.

What is the AZ-204 Exam?

So what exactly is the AZ-204 (Developing Solutions For Microsoft Azure) exam all about? In short, the AZ-204 exam is aimed at Cloud Developers already familiar with the Azure platform. It aims to demonstrate proficiency with developing solutions on the Microsoft Azure cloud.

Passing this single exam will earn you the Microsoft Azure Developer Associate Certification .

This exam replaces the older AZ-203 exam (Developing Solutions for Microsoft Azure) .

You can find more information about the exam at the below link: https://docs.microsoft.com/en-us/learn/certifications/exams/az-204

Who is the Certification For?

The AZ-204 exam is suitable for developers that:

• Want to prove their Azure cloud knowledge and skills
• Want to learn more about the Azure cloud
• Want to become a better developer

Before you sit this exam you should ideally have at least 1-2 years professional development experience, including experience with Microsoft Azure. In addition, you should have a certain degree of proficiency with the Azure SDKs, Azure PowerShell, Azure CLI, data storage, data connections, APIs, app authentication and authorization, compute and container deployment, debugging, performance tuning, and monitoring.

My Exam Prep Strategy

My goal with this exam wasn’t to just ‘pass the exam’ but instead to retain my new found knowledge and put it into practice. For this reason I spent close to 3 months preparing for the exam.

Similar to some of the previous exams I’ve completed, my exam preparation strategy was as follows:

• Complete the Self Paced AZ-204 Online Training
• Completed Udemy Course
• Complete the Official AZ-204 Practice Exam
• Compiled a Mind Map of key concepts

What is Covered in the Exam?

The exam may contain questions that spans the below 5 domains:

Develop Azure compute solutions (25-30%)

Implement iaas solutions, create azure app service web apps, implement azure functions, develop for azure storage (10-15%), develop solutions that use cosmos db storage, develop solutions that use blob storage, implement azure security (15-20%), implement user authentication and authorization, implement secure cloud solutions, monitor, troubleshoot, and optimize azure solutions (10-15%), integrate caching and content delivery within solutions, instrument solutions to support monitoring and logging, connect to and consume azure services and third-party services (25-30%), develop an app service logic app, implement api management, develop event-based solutions, microsoft learn – self-paced online training.

Microsoft offers FREE self-paced online training that specifically covers many of the key concepts covered in the AZ-204 exam.

The training is split across multiple modules that you can complete at your own pace. Some of the modules include hands-on practical work using a temporary Azure trial subscription – in case you don’t already have an Azure subscription.

Prior to sitting the exam I completed all modules over a period of around 3 weeks.

Below are links to the self-paced training modules:

• Creating Serverless Applications
• Connect your services together
• Store data in Azure
• Deploy a website with Azure virtual machines
• Manage resources in Azure
• Deploy a website to Azure with Azure App Service
• Secure your cloud data

Udemy Online Training

Udemy is an online learning platform that offers over 155,000 different courses across a range of different subjects and has a user base of more than 35 million users around the world.

On the recommendation of my fellow colleagues that had passed the AZ-204 exam, I purchased and watched some Udemy training courses.

I initially started with the AZ-204 exam prep course from Scott Duffy . Overall, Scott is a great trainer, the course is very well structured and covers all the key domains covered in the exam, including a practice test right at the end of the course. Scott is engaging and is well spoken, however, after watching most of the course I felt that the content primarily focused on the higher level concepts rather than drilling into the finer details necessary for the exam.

So I decided to look at some other courses …

I then purchased the AZ-204 exam prep course by Alan Rodrigues on recommendation of another fellow colleague who had also recently passed the exam. After watching many of the modules I was very impressed with the sheer amount of quality content contained in this course, and the amount of detail contained in each module. It covers the high level concepts, as well as digging deep into the code which is essential to pass this exam. It also includes a practice exam as well. It’s clear that Alan has spent a lot of time preparing the materials for this course.

My Udemy Recommendation: If you don’t have much time to prepare or are only interested in understanding the high level concepts then I would recommend taking Scott Duffy’s course , however on the other hand, if you have the time available then I’d recommend taking Alan Rodrigues’s course as it covers the exam content in much greater depth.

A Cloud Guru Online Training

UPDATE: At the time I sat the AZ-204 exam, A Cloud Guru did not have a specific course for the AZ-204 exam, however they have recently released an AZ-204 exam course . So if you are already a subscriber then I would definitely recommend checking it out.

A Cloud Guru is basically an online learning platform that provide high-quality video courses focused on the cloud, including Microsoft Azure , Amazon Web Services and Google Cloud Platform . I’ve been a loyal subscriber of A Cloud Guru for quite sometime now.

I personally have used their courses a number of times in the past when studying for exams with great success. Even if you are not a subscriber, they also have great, FREE content on Youtube , including weekly news summaries of the major cloud providers. It’s definitely worth a look!

Free Microsoft Training + Exam Voucher

Microsoft periodically runs FREE AZ-204 exam training around the globe, and if you are lucky enough then there might be one happening near you, or available online.

Microsoft is known to give out free exam vouchers at these workshops. As an attendee you may be given the option of sitting the exam for FREE on the same day after the in-person workshop, or you given a FREE exam voucher which can be redeemed when booking the exam.

You can find a list of the upcoming Microsoft AZ-204 training at the following link: https://events.microsoft.com .

Mind Mapping

I’m a visual learner so I generally find it much easier to absorb visual forms of content (such as video, diagrams, charts, etc.) rather than text based materials such as books and articles. For this reason I used the Mind Mapping technique when preparing for the exam.

Mind mapping is a technique involving organising data into a visual layout. I used the FREE online mind mapping tool Coggle to create a mind map for the exam which I would periodically review to refresh my memory of the exam topics. If I couldn’t remember a specific concept then I would go back and study it again.

You can find my mind map below.

Official Reference Book

If you prefer to study from a reference book then you should consider checking out Microsoft’s official AZ-204 exam reference book . While I personally didn’t purchase the book, I know it may appeal to others out there that prefer text books.

Sitting the Exam

The exam contains around 45 to 60 questions, including a combination of multiple choice questions , scenario-based questions and case studies . You have 180 minutes to complete the exam, requiring a minimum score of 700 to pass – which I believe equates to around 70%.

Based on my previous experience sitting other Microsoft exams, my strategy for the exam involved a 2-pass approach. I would spend a maximum of 2 minutes per question on the first pass. If I encountered any questions I wasn’t sure about, I would mark it for ‘review’ so that I could come back and review these later.

Be aware that the exam questions can be quite tricky, so it’s important to pay very close attention to the wording of each question . Sometimes a single word can completely change the context of a given question.

You can book the exam through the AZ-204 exam page . You have the option of either completing the exam online or in-person at an exam center. I opted to complete it online because it was more convenient for me.

Note: If you are planning to sit the online exam then I’d recommend that you run the mock test on your workstation at least 1 day before the exam to ensure there are no issues. In my case, my workstation had issues running the exam software, therefore I used an alternative laptop.

Also, some people have noted that they encountered exam questions regarding Kubernetes – even though Microsoft officially states that it is out-of-scope for the exam. Although I personally didn’t encounter any such questions I would suggest that you familiarise yourself with the topic just in case.

How Did I go?

I passed the exam on my first attempt with a score of 840. Yay!

Overall, I found the exam to be the most challenging Microsoft exam I’ve sat to date, therefore I was glad that I had put in the extra effort to prepare for it.

Immediately after completing the exam you’ll be informed of the result. Around a day or so later, you should see your certification appear in the Microsoft Learning portal .

You’ll also be able to download your badge from Acclaim .

Final Thoughts

I hope this AZ-204 exam study guide has helped you in your preparation for the exam.

I’d love to hear of your experiences of the exam, or any general tips you may have. Feel free to share them in the comments below.

Best wishes for the exam!

Thank you so much for the details.

24th April 2021 at 12:11 am

Hi, Thanks for the information. Wanted to ask if only the Udemy course by Alan be sufficient enough to prepare for the exam? Or should I also go through Microsoft document for each topic and Microsoft learn path too?

24th April 2021 at 5:35 am

Assuming you’ve already got some level of hands-on experience with Azure, Alan’s course combined reviewing the docs should be sufficient for the exam.

7th May 2021 at 6:20 am

Good Work. Really Helpful. Thanks

18th May 2021 at 10:08 am

Congratulations. I am a Sr SAP developer and wanted to switch to Azure. I don’t have any hands-on experience in Azure. Is it too difficult to clear AZ-204 without prior experience in Azure.

18th May 2021 at 12:03 pm

Hi Rajesh, The Az-204 exam is quite intensive. In your case, I personally wouldn’t recommend the Az-204 exam, instead I would recommend the AZ-900 exam first. From there you can move onto the Az-204. All the best!

18th May 2021 at 12:08 pm

Thanks Shane for your response. Yes, I completed Az-900 certification last week and was thinking of starting AZ-204. Sorry, I should have mentioned this in my earlier post.

18th May 2021 at 6:44 pm

In that case give it a shot! Easiest way to tell if you’re ready is to try sit a practice exam, you can either sit the official MS exam from MeasureUp or even one of the prac exams from the Udemy courses that I suggested.

20th January 2023 at 5:46 am

Thank you very much! This is a really helpful post.

Q] You have to deploy a microservice-based application to the Azure Kubernetes cluster. The solution has the following requirements:

• Reverse proxy capabilities
• The ability to configure traffic routing, and,
• Termination of TLS with a custom certificate

Which of the following would you use to implement a single public IP endpoint to route traffic to multiple microservices?

• Ingress Controller
• Virtual Kubelet

Explanation: First, you need to know that Ingress is an object that manages external access to services in a cluster.

One of the main reasons to use an ingress controller is that by using a single IP address, you can route traffic to multiple services in a Kubernetes cluster.

The documentation mentions that an ingress controller is a piece of software that provides reverse proxy, configurable traffic routing, and TLS termination for Kubernetes services, all of which are a requirement in the question.

So, option 1 is the correct choice.

Q] A company has a web application deployed using the Azure Web App service. The current service plan being used is D1.

It needs to ensure that the application infrastructure can automatically scale when the CPU load reaches 85%. You also have to ensure costs are minimized.

Which of the following steps would you implement to achieve the requirements? Choose 4 answers from the options given below:

• Enable autoscaling on the Web application.
• Configure a scale condition.
• Configure the web application to use the Standard App Service Plan.
• Configure the web application to use the Premium App Service Plan.
• Add a scale rule.

Explanation: Well, the app service plan D1 is only for the shared infrastructure and so contains only a limited number of features. For the D1 plan, autoscaling is not supported. So, the application cannot scale automatically when the CPU load reaches 85%.

To enable autoscaling, you need to upgrade the app service plan tier. Plans like B1, B2, and B3 enable you to scale manually but not automatically.

Autoscaling is only available for the standard and the premium plans.

So, these are the following steps to implement:

• First, we need to configure the web application to use the standard app service plan. Note that the premium app service plan works too, but since we need to ensure that costs are minimized too, option 4 is incorrect.
• And, since we need to select a total of 4 options, all the other 3 options must be selected to achieve the requirement.

Q] You deploy a web application to Azure with App Service on Linux. You then publish a custom docker image to the Azure Web App.

Suppose you need to access the console logs generated from the container in real-time. Which of the following would go into Slot1 in this Azure CLI script?

az webapp log Slot1 --name testapp --resource-group test-rg Slot2 filesystem

az Slot3 log Slot4 --name testapp --resource-group test-rg

Explanation: To configure logging, we use the command az webapp log config . Option 1 is the correct choice.

You can easily ignore the other options as it is evident from their names that:

download downloads a web app’s Log history as a zip file,

show gets the details of a web app’s logging configuration and,

tail starts live log tracing for a web app.

Implement input and output bindings for a function

Azure Functions triggers and bindings concepts

Test your knowledge on Azure Function Bindings

Q] You develop an Azure Function that performs the following activities:

• Read messages from an Azure Storage Queue, and,
• Process the messages and add entities to Azure Table Storage

You have to define the correct bindings in this function.json file.

Which of the following would go into Slot 1?

• “in”
• “out”
• “trigger”
• “$return”

Explanation: Since we need to read messages from the Azure Storage Queue, an Azure Queue Storage trigger is defined as the first element in the binding array.

And since we need to process and add entities to Azure table storage, the second element in the array defines the Azure Table Storage output binding.

So, the binding direction will be out (slot 2) for the 2nd item in the array since it is an output binding. And the binding direction for triggers (slot 1) is always in.

Option 1 is the correct choice.

Reference Link : Azure Functions trigger and binding

Binding direction in Azure Functions

Test your knowledge on Azure Storage Account

Q] You have to implement the azcopy tool to copy objects from a local folder named ‘Contoso’ in the ‘D’ drive to a container named ‘demo’ in a storage account.

And, the command azcopy is given which copies all the objects in the local folder.

Which of the following would go into Slot2?

• contoso.blob.core.windows.net/demo
• contoso.blob.windows.net/demo

Explanation: To copy objects with the azcopy tool, use the azcopy command with the copy keyword. Then comes the local directory from where the objects need to be copied. Next comes the destination URL of the target container in the storage account.

Clearly options 3 and 4 are incorrect. Option a is the correct answer as the correct URL for a storage account will be in the format <name>.blob.core.windows.net. And, demo is the name of the container.

The characters that you see after the container name are for the SAS token.

Q] You build a web application that’s deployed to Azure. The application would not allow anonymous access and the authentication would be carried out via Azure AD. Further, the application needs to abide by the following requirements:

• Users must be able to log into the web application using their Azure AD credentials
• The personalization of the web application must be based on the membership in Active Directory groups

You have to configure the application manifest file. Which of the following would go into Slot2?

• allowPublicClient
• oauth2Permissions
• requiredResourceAccess
• oauth2AllowImplicitFlow

Explanation: First, see the below application manifest file which sometimes you would edit to configure the attributes of an application in Azure Active Directory.

All the applications contain something called appID which is nothing but the application ID or the Client ID.

From the question, it is evident that the attribute (in slot2) will have a value of type Boolean.

Now, to meet the requirements in the question, you would set the value of the attribute oauth2AllowImplicitFlow to True.

This attribute specifies whether a web app can request OAuth2.0 implicit flow access tokens for browser-based apps, like single-page apps.

So, option 4 perfectly fits what’s asked in the question.

Options oauth2Permissions and requiredResourceAccess represent a value of type Collections so you can easily ignore them.

Reference Link : Azure Active Directory app manifest

Q] You develop an ASP.Net Core application that works with blobs in an Azure storage account. The application authenticates via Azure AD credentials.

Role-based access has been implemented on the containers that contain the blobs. These roles have been assigned to the users.

You have to configure the application so that the user’s permissions can be used with the Azure Blob containers.

Which of the following would you use as the Permission for the Microsoft Graph API?

• user_impersonation

Explanation: First, log in to the Azure portal and create a new app registration in the Azure Active Directory for the ASP.Net Core application.

Click ‘App registrations’ and then click ‘New registration.’ Enter a name for your app and then click ‘Register’ to create the app.

If you check the API permissions for the app, by default, the registered Azure AD application has access to the Microsoft Graph API.

And the permission used by the app for accessing Microsoft Graph API is User.Read. So, option 1 is the right choice.

Test your knowledge on Azure Application Insights

Q] A developer needs to enable the Application Insights Profiler for Azure Web App. Which of the following feature is a prerequisite to enable the Profiler?

• CORS configuration
• Always On setting
• Enable Identity
• Enable Custom domains

Explanation: Azure Application Insights Profiler provides performance traces for applications that are running in production in Azure.

Enabling Identity is part of Azure Active Directory and is not related to Application Insights Profiler.

Custom domains are a feature to access any Azure URI by a different or a customized URI. Hence this is not related to Application Insights Profiler.

Cross-origin resource sharing (or CORS) defines a way for web applications in 1 domain to interact with resources in another domain. CORS will not help in enabling Application Insights Profiler.

To enable Application Insights Profiler for a web App, the correct prerequisite is to enable ‘Always On.’

This is required because if a web app is idle for too long, Azure App Service unloads the website, and it only loads the website again when the traffic returns. By enabling ‘Always On’, you keep the Web App up and running all the time.

Q] A company is building a traffic monitoring system. The system monitors the traffic along 4 highways and is responsible for producing a time series-based report for each highway.

The traffic sensors on each highway have been configured to send their data to Azure Event Hubs. The data from Event Hubs is then consumed by three departments. Each department makes use of an Azure Web App to display the data.

You have to implement the Azure Event Hub instance and ensure that data throughput is maximized and latency is minimized.

Which of the following would you use as the partition key?

Explanation:  The scenario in the question is best understood with the help of the diagram below:

Since the data comes in for each highway, the highway represented by probably a highway number would be ideal for the partition key.

The other options are incorrect since they would not provide ideal values for the distribution of data across the partitions.

Test your knowledge of Azure Service Bus

Q] You develop an application that makes use of Azure Service Bus. You create filters based on different types of subscribers that would subscribe to the topic.

Which of the following would you use as the filter condition for the requirement?

“Subscribers should be able to receive all messages being sent to the topic”

• Boolean filters
• Primary filters
• SQL filters
• Correlation filters

Explanation: Well, Azure Service Bus supports 3 different filter conditions: They are:

• SQL filters, and,
• Correlation filters.

Correlation filters have a set of conditions that are matched against the arriving messages.

SQL filter holds a SQL-like conditional expression that’s evaluated against the incoming messages.

Boolean filters cause either all or none of the arriving messages to be selected for the subscription.

Since the question mentions that we need to receive all messages sent to the topic, a Boolean filter would be more suitable.

Option 1 is the correct choice

Even for sites with only one instance, Standard mode has an enterprise-grade SLA (Service Level Agreement) of 99.9% monthly. Standard mode differs from the other ways to purchase Windows Azure Web Sites in that it runs on dedicated instances.

Refer: Best Practices: Windows Azure Websites (WAWS)

Q2) To process Azure Storage blob data, you create an HTTP triggered Azure Function app. An output binding on the blob is used to start the app. After four minutes, the app continues to time out. The blob data must be processed by the program. You must guarantee that the app does not time out and that the blob data is processed. To process the blob data, use the Durable Function async pattern. Is the solution effective in achieving the goal?

Correct Answer: No

Explanation: Instead, send the HTTP trigger payload to an Azure Service Bus queue, where it will be handled by a queue trigger function, and you’ll get an HTTP success response right away. Large, long-running functions can result in unanticipated timeouts. Refactor huge functions into smaller function sets that work together and produce results quickly whenever possible, according to general best practices. A webhook or HTTP trigger function, for example, may need an acknowledgment response within a particular time limit; webhooks frequently demand an immediate response. The HTTP trigger payload can be placed in a queue and processed by a queue trigger function. This method allows you to postpone the actual task and respond quickly.

Refer: Azure Blob storage trigger for Azure Functions

Q9)You’re getting ready to publish a website from a GitHub repository to an Azure Web App. A script generates static material for the webpage. You intend to use the continuous deployment functionality of Azure Web Apps. Before the website starts delivering traffic, you must run the static generating script. What are two options for achieving this goal? Each accurate response provides a comprehensive solution. NOTE: One point is awarded for each correct answer.

•  Add the path to the static content generation tool to WEBSITE_RUN_FROM_PACKAGE setting in the host.json file.
•  Add a PreBuild target in the websites csproj project file that runs the static content generation script.
• Create a file named run.cmd in the folder /run that calls a script which generates the static content and deploys the website.
• Create a file named .deployment in the root of the repository that calls a script which generates the static content and deploys the website.

Correct Answer: Add the path to the static content generation tool to WEBSITE_RUN_FROM_PACKAGE setting in the host.json file and Create a file named .deployment in the root of the repository that calls a script which generates the static content and deploys the website.

Explanation: Your functions can be run straight from a deployment package file in your function app in Azure. To enable your function app to run from a package, just add a WEBSITE RUN FROM PACKAGE setting to your function app settings. Include a.deployment file in the repository root to personalise your deployment. You only need to add a file with the name.deployment and the following content to the root of your repository: COMMAND TO RUN FOR DEPLOYMENT [config] command = YOUR COMMAND TO RUN FOR DEPLOYMENT This command can simply be used to run a script (batch file) that contains everything you need for your deployment, such as moving files from the repository to the web root directory.

Refer: Run your functions from a package file in Azure

Q10)You’re working on a web application that’s being secure by the Azure Web Application Firewall (WAF). The web app’s traffic is route through an Azure Application Gateway instance that is share by several web apps.  Contoso.azurewebsites.net is the URL for the web app. SSL must be use to secure all traffic. Multiple web apps use the Azure Application Gateway instance.For the web app, you must configure Azure Application Gateway.Which of the two acts should you take? Each accurate response reveals a piece of the solution.

• In the Azure Application Gateway’s HTTP setting, enable the Use for App service setting.
•  Convert the web app to run in an Azure App service environment (ASE).
• Add an authentication certificate for contoso.azurewebsites.net to the Azure Application Gateway.
• In the Azure Application Gateway’s HTTP setting, set the value of the Override backend path option to contoso22.azurewebsites.net.

Correct Answer: In the Azure Application Gateway’s HTTP setting, enable the Use for App service setting. In the Azure Application Gateway’s HTTP setting, set the value of the Override backend path option to contoso22.azurewebsites.net.

Explanation: The HTTP settings define the ability to specify a host override, which may be applied to any back-end pool during rule construction. The ability to extract the host name from the back-end pool members’ IP or FQDN. If configured with the option to derive host name from an individual back-end pool member, HTTP settings now enable the option to dynamically pick the host name from the FQDN of a back-end pool member. With multi-tenant services, SSL termination and end-to-end SSL are require. Trusted Azure services, such as Azure App service web apps, do not require whitelisting the backends in the application gateway when using end-to-end SSL.As a result, no authentication certificates are require.

Refer: Configure App Service with Application Gateway

Q11)You’re creating a website that stores data on Azure Blob storage. After 30 days, you configure the Azure Blob storage lifecycle to migrate all blobs to the archive layer. For data older than 30 days, customers have sought a service-level agreement (SLA). The minimal service level agreement (SLA) for data recovery must be document. What type of SLA should you use?

•  at least two days
• between one and 15 hours
• at least one day
• between zero and 60 minutes

Correct Answer: between one and 15 hours

Explanation: The lowest storage cost is in the archive access tier. However, in comparison to the hot and cool tiers, it has higher data retrieval costs. Depending on the priority of the request, retrieving data from the archive tier can take several hours. In the case of minor objects, a high priority rehydrate may be able to retrieve the object from the archive in less than an hour.

Refer: Hot, Cool, and Archive access tiers for blob data

Q12) You are in charge of creating Azure solutions. When an Azure virtual machine finishes processing data, a message must be sent to a.NET application. The communications must not be kept after the receiving program has processed them. The.NET object that will receive the messages must be implement. Which object do you think you should use?

• QueueClient
• SubscriptionClient
• TopicClient
• CloudQueueClient

Correct Answer: CloudQueueClient

Explanation: A queue allows a single consumer to handle a message. To access the Azure VM, you’ll need a CloudQueueClient.

Refer: Service Bus queues, topics, and subscriptions

Q13)You already have an Azure storage account where you store enormous amounts of data in various containers. All data from the previous storage account must be copied to the new storage account. The copying procedure must meet the following criteria: Data movement should be automated. Reduce the amount of user input necessary to complete the operation. Ascertain that the data transportation procedure can be recover. What type of material should you use?

•  AzCopy
• Azure Storage Explorer
•  Azure portal
• .NET Storage Client Library

Correct Answer: AzCopy

Explanation: Using the AzCopy v10 command-line utility, you can copy blobs, folders, and containers between storage accounts. Since the copy operation is synchronous, when the command completes, it means all files have been copied.

Refer: Copy blobs between Azure storage accounts by using AzCopy

Q14)You’re utilising the Azure Cosmos DB SQL API to create an Azure Cosmos DB solution. There are millions of documents in the database. Hundreds of properties can be found in a single document. There are no distinct partitioning values in the document properties. Azure Cosmos DB must scale individual database containers to fulfil the application’s performance requirements by distributing the workload evenly across all partitions over time. You must choose a partition key. Which two partition keys are available to you? Each accurate response provides a comprehensive solution.

•  a single property value that does not appear frequently in the documents
•  a value containing the collection name
•  a single property value that appears frequently in the documents
•  a concatenation of multiple property values with a random suffix appended
•  Further, a hash suffix appended to a property value

Correct Answer: a concatenation of multiple property values with a random suffix appended and a hash suffix appended to a property value

Explanation: Concatenating numerous property values into a single artificial partition key property can be use to create a partition key.  Appending a random integer to the end of the partition key value is another way to divide the burden more equitably. You can do parallel write operations across partitions when you distribute items this way.

Refer: Create a synthetic partition key

Q15)You’ve added a new Azure subscription to your account. You are developing an internal website for employees to view sensitive data.

Cloud computing Engineers and Developers are among the 10 highest paid IT sector jobs in 2022. Organizations of all sizes are now ready to pay a hefty sum to these certified cloud developers, capable of bridging the existing technical skill gap within their teams. No wonder it is the most opportune time to become a Certified Cloud developer and Microsoft Azure is surely one of the most promising cloud platforms. More and more companies are expressing incremental demand for Azure certified professionals. Moreover, once you get Azure certified, you need not stop learning and up-skilling. Since associate exams are usually valid for 1 - 2 years only, you have to renew your certifications to keep yourself updated with changes in lieu of the ever-evolving nature of technology.

If you have the time to invest, a great way to motivate and challenge yourself is to skill up in other technologies as well.

The company is based in Canada and has retail store locations across the world. The company is developing several cloud-based solutions to support their stores, distributors, suppliers, and delivery services. Current environment - Corporate website - The company provides a public website located at http://www.vanarsdelltd.com. The website consists of a React JavaScript user interface, HTML, CSS, image assets, and several APIs hosted in Azure Functions. Retail Store Locations - The company supports thousands of store locations globally. Store locations send data every hour to an Azure Blob storage account to support inventory, purchasing and delivery services. Each record includes a location identifier and sales transaction information. Requirements - The application components must meet the following requirements: Corporate website - • Secure the website by using SSL. • Minimize costs for data storage and hosting. • Implement native GitHub workflows for continuous integration and continuous deployment (CI/CD). • Distribute the website content globally for local use. • Implement monitoring by using Application Insights and availability web tests including SSL certificate validity and custom header value verification. • The website must have 99.95 percent uptime. Retail store locations - • Azure Functions must process data immediately when data is uploaded to Blob storage. Azure Functions must update Azure Cosmos DB by using native SQL language queries. • Audit store sale transaction information nightly to validate data, process sales financials, and reconcile inventory. Delivery services - • Store service telemetry data in Azure Cosmos DB by using an Azure Function. Data must include an item id, the delivery vehicle license plate, vehicle package capacity, and current vehicle location coordinates. • Store delivery driver profile information in Azure Active Directory (Azure AD) by using an Azure Function called from the corporate website. Inventory services - The company has contracted a third-party to develop an API for inventory processing that requires access to a specific blob within the retail store storage account for three months to include read-only access to the data. Security - • All Azure Functions must centralize management and distribution of configuration data for different environments and geographies, encrypted by using a company-provided RSA-HSM key. • Authentication and authorization must use Azure AD and services must use managed identities where possible. Issues - Retail Store Locations - • You must perform a point-in-time restoration of the retail store location data due to an unexpected and accidental deletion of data. • Azure Cosmos DB queries from the Azure Function exhibit high Request Unit (RU) usage and contain multiple, complex queries that exhibit high point read latency for large items as the function app is scaling. You need to test the availability of the corporate website. Which two test types can you use? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

• A. Standard
• B. URL ping
• C. Custom testing using the TrackAvailability API method
• D. Multi-step
