Each of these domains carries specific weightings, with compute and storage solutions typically forming a major portion of the exam. Familiarizing yourself with this structure helps prioritize your learning schedule and avoid spending disproportionate time on low-impact topics.

Microsoft provides a free downloadable exam skills outline. This document should be your blueprint. Print it, annotate it, and use it as a checklist to track your progress.

The Importance of Hands-On Experience

AZ-204 is not an exam that can be passed solely by watching tutorials or reading whitepapers. Microsoft designs its exams with the assumption that candidates have hands-on experience. This is evident in the question formats, many of which present real-world scenarios that require a combination of logic, practical knowledge, and technical discernment.

Set up your own Azure environment using the free tier or a Visual Studio subscription credit. Begin by working with services like:

• Azure App Services

• Azure Functions

• Azure Blob Storage

• Cosmos DB

• Azure Key Vault

• Azure CLI and Azure PowerShell

• Azure SDKs for C# and JavaScript

Experiment with deploying simple apps, implementing authentication using Azure AD, managing secrets with Key Vault, and automating deployments using ARM templates or Bicep.

This tactile familiarity will prove indispensable when faced with scenario-based exam questions that test not just what you know, but how you apply it.

Using Practice Exams as a Diagnostic Tool

While it may be tempting to leave practice exams for the final stages of your preparation, they are best used as diagnostic tools from the outset. Starting early with mock exams allows you to identify knowledge gaps before they become barriers.

In my own preparation, I found Microsoft’s official practice tests (and AZ-203 equivalents) to be exceptionally helpful. They simulate the structure and logic of actual exam questions, providing not only familiarity but also a lens into how Microsoft expects candidates to interpret scenarios.

Be aware of subtle formatting features in the test environment:

• Some questions contain additional code or context hidden under an “Excerpt” or “More Info” tab.

• Expect various formats: single-answer multiple choice, multi-answer selections, drag-and-drop ordering, and scenario analysis.

• The real exam awards partial credit for multi-part answers, unlike many practice tests that use an all-or-nothing scoring method.

If you activate your practice test provider early, you’ll often find multiple sets of questions grouped by topic. These can be a great way to modularize your study and assess your progress week by week.

Developing Fluency with Azure SDKs and the CLI

One of the unique challenges of the AZ-204 exam is the dual emphasis on both conceptual understanding and practical implementation. Many questions will require you to identify the correct SDK methods, CLI commands, or deployment strategies.

This is especially true for tasks involving:

• Creating and managing resources

• Implementing secure access to storage or databases

• Interacting with APIs

• Configuring monitoring and diagnostics

Get comfortable using both the Azure CLI and the Azure SDK for your preferred programming language (most often C#). Practice common tasks such as:

• Deploying and configuring Azure App Services

• Creating Azure Functions using Visual Studio Code

• Uploading and downloading blobs with the Storage SDK

• Using the Azure Identity library for secure authentication

• Running batch operations using CLI scripts

You don’t need to memorize every command or method signature, but fluency with the development tools will make exam scenarios more intuitive and easier to decode.

Recognizing the Nuances Between Similar Services

A recurring theme in the AZ-204 exam is the necessity to distinguish between similar Azure services. For instance, knowing when to use Azure Table Storage versus Cosmos DB, or Azure Functions versus WebJobs, is crucial.

These kinds of questions typically present a scenario with specific requirements such as latency, scalability, cost sensitivity, or compliance. Your task is to select the Azure service that best aligns with those requirements.

To master these questions, do the following:

• Study service comparison tables on Microsoft Learn and the official documentation

• Take notes on subtle differentiators like throughput models, SLA guarantees, or integration capabilities

• Build small prototypes using overlapping services to get a feel for how each behaves under different configurations

Examples of commonly conflated services include:

• Azure SQL Database vs. Cosmos DB

• Blob Storage vs. File Storage

• Event Grid vs. Service Bus vs. Event Hub

• Azure Logic Apps vs. Azure Functions

• Managed Identity vs. Service Principal for authentication

Being able to justify a choice based on a set of constraints is exactly the type of higher-order thinking the AZ-204 exam seeks to evaluate.

Mastering Azure Resource Deployment and Management

Resource provisioning and configuration is another central pillar of this exam. You need to understand not just how to create resources, but also how to automate their deployment, secure them, and monitor their behavior over time.

Practice these tasks thoroughly:

• Use ARM templates and Bicep files for declarative deployments

• Manage infrastructure using the Azure CLI

• Integrate diagnostic settings for logging and metrics

• Create alert rules and action groups for performance and availability

• Assign permissions using role-based access control (RBAC) and understand how it differs from policies

A well-prepared candidate should be able to look at a JSON template or a YAML pipeline and identify if something is misconfigured or inefficient.

Exploring the Microsoft Learn Platform

The Microsoft Learn platform provides a vast array of free learning paths that align directly with the AZ-204 skill requirements. This content is modular, interactive, and written by Azure experts.

For a time-efficient and targeted study plan, follow these Microsoft Learn paths:

• Develop solutions that use Cosmos DB

• Implement secure cloud solutions

• Monitor, troubleshoot, and optimize Azure applications

• Connect to and consume Azure services and third-party services

These modules include sandbox environments, which allow you to execute real operations in Azure without needing a subscription. This is an excellent opportunity to validate your knowledge with hands-on labs in a controlled setting.

While you don’t have to complete every exercise, make sure to at least skim through each module, paying attention to unique use cases, service limitations, and integration tips.

Using Community Resources and Curated Study Guides

The Azure developer community is active and incredibly supportive. Countless blogs, YouTube channels, GitHub repositories, and Discord servers are dedicated to helping learners navigate Microsoft certifications.

A few community-driven resources worth mentioning:

• GitHub repositories that organize AZ-204 topics by learning module

By triangulating official documentation with real-world insights from professionals, you gain a richer understanding of the practical applications of Azure services.

Embracing the Right Mindset and Study Rhythm

Finally, it’s important to cultivate the right mindset. The AZ-204 exam can feel overwhelming at first due to the sheer number of services and features it covers. However, not all of them are tested equally.

Here are a few principles that kept me grounded:

• Focus on core services first (App Services, Functions, Storage, Identity)

• Practice building solutions rather than just reading about them

• Don’t aim for perfection in every domain—aim for competency across all

• Use downtime for passive reinforcement (e.g., listening to Azure podcasts or reviewing flashcards)

Establish a study rhythm that fits your schedule. For example, dedicate two weeks to compute solutions, one week to storage, one to security, and one for revision and practice tests. This structured approach builds confidence and reduces last-minute cramming.

Establishing the Foundation

The AZ-204 certification is a gateway to becoming a proficient Azure developer and opens the door to more advanced certifications like AZ-400 (DevOps Engineer) or the Microsoft Certified: Azure Solutions Architect Expert.

This series has focused on helping you understand the structure of the exam, set up an effective study environment, and begin developing the hands-on fluency required for success.

we will take a deeper dive into Azure compute services—such as Azure Functions, App Services, containers, and deployment pipelines—offering tactical advice on how to approach each topic area. We’ll also explore practical coding exercises that can help simulate real-world scenarios likely to appear in the exam.

Azure compute services form the architectural backbone of cloud-native applications. From serverless execution to full-blown container orchestration, these services define how your application’s logic is deployed, executed, scaled, and monitored. For the AZ-204 exam, mastery of compute solutions is non-negotiable. This part of the series offers a comprehensive and tactical look at the compute domain—exploring real-world nuances, deployment strategies, integration techniques, and performance management essentials.

Deep Dive into Azure App Services

Azure App Service is one of the most frequently encountered services in the AZ-204 exam. It offers a managed platform for building and hosting web apps, RESTful APIs, and backend services in various languages.

You must be proficient in deploying to Azure App Services using different methods:
