AZ-204 Exam Domains 2026: Complete Guide to All 5 Content Areas

TL;DR
  • Develop Azure compute solutions carries the highest weight at 25-30% of the exam.
  • Connect to and consume Azure services follows closely at 20-25%, so it deserves equal study attention.
  • Storage and Security domains are tied at 15-20% each, covering distinct but overlapping skill sets.
  • Monitoring is the smallest domain at 5-10% but still tests App Insights and diagnostic logging in depth.

Overview of the AZ-204 Exam Domains

The AZ-204 exam validates the skills of a developer who designs, builds, tests, and maintains applications on Microsoft Azure. Instead of grading you on generic cloud theory, Microsoft organizes the exam into five weighted content areas, each mapped to a specific slice of real-world Azure development work. Understanding these domains isn't optional - it's the single most efficient way to allocate limited study hours before sitting the proctored Pearson VUE or OnVUE exam.

This guide breaks down all five domains with their official weightings, the concrete skills tested inside each one, and how they interact with the exam's 100-minute time limit and 700-point passing threshold. If you're just starting your prep, pair this with the AZ-204 Study Guide 2026 for a full first-attempt strategy, or check What Is AZ-204? if you need the certification's basic context first.

Why Domain Weighting Matters: Microsoft publishes weight ranges, not fixed percentages, meaning any given exam version can shift emphasis within those bands. Treat the higher-weighted domains as your baseline priority, but don't skip the smaller ones entirely - every domain still contributes scored items toward your 700-point threshold.

Domain 1: Develop Azure Compute Solutions (25-30%)

This is the largest domain on the exam and the one most candidates underestimate in scope. It covers how applications actually run on Azure - from serverless Functions to containerized workloads to full App Service deployments.

Develop Azure Compute Solutions

Candidates must understand how to implement and manage compute resources across multiple Azure hosting models, including provisioning, configuration, and code-level implementation.

  • Implementing Azure App Service web apps, including deployment slots and configuration
  • Creating and configuring Azure Functions, including triggers, bindings, and durable functions
  • Provisioning and configuring virtual machines for application workloads
  • Creating and managing container images for solutions, including Azure Container Instances and Azure Container Apps
  • Implementing Azure Kubernetes Service (AKS) fundamentals for containerized apps

Because this domain spans so many services, candidates often benefit from working through it in isolation before mixing in the other domains. The dedicated AZ-204 Domain 1 study guide breaks each compute service into hands-on labs you can replicate in a free Azure sandbox.

Domain 2: Develop for Azure Storage (15-20%)

Storage questions test whether you know when to reach for Cosmos DB versus Blob Storage versus a relational option, and how to write code that interacts with each correctly.

Develop for Azure Storage

Expect scenario-based questions asking you to choose the right storage service and implement the correct SDK calls or CLI commands for a given requirement.

  • Developing solutions that use Azure Cosmos DB, including partitioning and consistency levels
  • Developing solutions that use Azure Blob Storage, including lifecycle management and access tiers
  • Setting and retrieving properties and metadata programmatically
  • Implementing data movement and processing pipelines with storage-connected APIs

This domain overlaps heavily with Domain 5 because storage services are frequently accessed through connected APIs and SDKs. For a deeper breakdown of exact objectives, see the AZ-204 Domain 2 guide.

Domain 3: Implement Azure Security (15-20%)

Security questions on AZ-204 aren't abstract - they're implementation-focused, testing whether you can wire up authentication and authorization correctly in code, not just describe concepts.

Implement Azure Security

This domain measures your ability to secure app identities, secrets, and access using Microsoft Entra ID (Azure AD) and related services.

  • Authenticating and authorizing users and apps using the Microsoft identity platform
  • Implementing shared access signatures and managed identities
  • Securing app configuration data using Azure Key Vault and App Configuration
  • Implementing solutions that use OAuth2 flows and Microsoft Graph permissions

Key Takeaway

Managed identities and Key Vault integration show up repeatedly across security scenarios - practice implementing both from scratch rather than just reading about them.

The full objective list with example code patterns is covered in the AZ-204 Domain 3 study guide.

Domain 4: Monitor, Troubleshoot, and Optimize Azure Solutions (5-10%)

This is the smallest domain by weight, but don't dismiss it - questions here test practical debugging skills that show up on the job constantly.

Monitor, Troubleshoot, and Optimize Azure Solutions

Expect questions on instrumenting applications for observability and diagnosing performance issues using native Azure tooling.

  • Implementing Application Insights for logging, metrics, and distributed tracing
  • Implementing code that handles transient faults and retry logic
  • Analyzing and troubleshooting solutions using Azure Monitor and Log Analytics
  • Optimizing application performance through caching strategies

Because this domain is small, many candidates schedule it last in their prep - but its content connects directly to real production skills employers expect. The Domain 4 guide walks through Application Insights setup step by step.

Domain 5: Connect to and Consume Azure Services and Third-Party Services (20-25%)

This domain is the second-largest on the exam and frequently underestimated because its name sounds generic. In practice, it covers API integration, messaging, and event-driven architecture - core patterns for almost every modern Azure application.

Connect to and Consume Azure Services and Third-Party Services

You'll need to implement API integration patterns, message-based communication, and event-driven solutions using Azure's messaging backbone.

  • Developing solutions using Azure Service Bus and Azure Queue Storage for messaging
  • Developing solutions using Event Grid and Event Hubs for event-driven architectures
  • Implementing API Management to secure, publish, and version APIs
  • Developing App Service Logic Apps for workflow automation
  • Implementing solutions that call third-party or Microsoft Graph APIs

Because this domain sits so close to Domain 1's weight, many test-takers treat compute and connectivity as a matched pair when scheduling review sessions.

How Domain Weighting Should Shape Your Study Order

With five domains carrying different weight bands, a flat "study everything equally" approach wastes time. A more efficient sequence front-loads the two heaviest domains - compute (25-30%) and connectivity (20-25%) - since together they can account for roughly half the exam, then works down through storage and security before finishing with monitoring.

Week 1-2

Domain 1: Compute

  • Build and deploy an App Service app with slots
  • Write and test an Azure Function with multiple trigger types
  • Deploy a container to Azure Container Apps
Week 3

Domain 5: Connectivity

  • Configure Service Bus queues and topics
  • Build an Event Grid subscription handler
  • Set up API Management policies
Week 4

Domain 2 & 3: Storage and Security

  • Implement Cosmos DB partitioning
  • Configure managed identity and Key Vault access
Week 5

Domain 4: Monitoring + Full Review

  • Instrument an app with Application Insights
  • Take timed practice exams to simulate the 100-minute limit

This sequencing tactic - pairing spaced review sessions with domain weight - is one of the few generic study techniques worth borrowing here, mainly because it maps cleanly onto AZ-204's own scoring structure.

Exam Format, Registration, and Fee Mechanics

AZ-204 is delivered exclusively through Pearson VUE, either at a physical test center or via OnVUE online proctoring. The exam fee is US$165 in the United States, with country-specific pricing elsewhere and no separate member or nonmember tier. Microsoft does not publish an exact question count, but most Microsoft certification exams - including this one - typically include 40 to 60 questions across a 100-minute session, mixing traditional multiple-choice items with case studies and possibly unscored questions used for future exam calibration.

Exam DetailSpecification

Time allotted100 minutes
Passing score700 or greater on a 1-1000 scale
Retake wait24 hours after first failed attempt
Renewal cycle12 months, free via Microsoft Learn assessment

A retake after a first failed attempt is allowed after just 24 hours, though later retake waiting periods increase. Results are typically available within minutes unless lab-based components are involved. Once you pass, the certification must be renewed every 12 months at no cost through an online Microsoft Learn assessment - but note that as of the current skills measured update (January 14, 2026), the AZ-204 certification, exam, and renewal assessments are scheduled to retire on July 31, 2026, after which point new certifications and renewals will no longer be possible. If cost planning matters to your decision, see the full AZ-204 Certification Cost breakdown.

No Formal Prerequisites, But Real Experience Expected: Microsoft doesn't require any prior certification to sit AZ-204, but recommends at least two years of hands-on programming experience along with familiarity with Azure SDKs, Azure CLI, PowerShell, data storage, APIs, authentication flows, and container deployment. Skipping this baseline is the most common reason candidates find the exam harder than expected - a topic covered further in How Hard Is the AZ-204 Exam?

Who Hires for AZ-204 Skills

The domain structure of AZ-204 mirrors real job responsibilities at companies building on Azure. Employers hiring cloud application developers, backend engineers, and integration specialists frequently list this certification because its five domains map directly onto day-to-day work: deploying compute resources, wiring up storage, securing identity flows, monitoring production apps, and integrating third-party APIs. Roles referencing Azure Functions, App Service, Service Bus, or Cosmos DB in job postings are effectively asking for the exact skill set this exam validates.

If you're evaluating whether this certification translates into better job prospects or pay, the AZ-204 Jobs page and the AZ-204 Salary Guide 2026 go deeper into hiring trends, while Is the AZ-204 Certification Worth It? weighs the broader return on investment.

Before you register, running through domain-specific practice questions on our AZ-204 practice test platform is one of the fastest ways to confirm which of these five areas needs the most additional review. Many candidates also use the full practice exam simulator to rehearse the 100-minute time constraint under realistic conditions before booking their Pearson VUE slot.
