Azure Developer Associate Certification
The Microsoft Azure Developer Associate (AZ-204) certification validates your expertise in designing, building, testing, and maintaining cloud applications and services on Microsoft Azure. This certification is essential for developers working with Azure services, SDKs, and cloud-native development patterns.
Unlike infrastructure-focused certifications, AZ-204 emphasizes hands-on coding, SDK usage, and application development best practices on Azure.
- Build web applications and APIs on Azure
- Develop serverless solutions with Azure Functions
- Work with Azure SDKs in C#, Python, JavaScript, or Java
- Implement cloud-native architectures
- Have 1-2 years Azure development experience
Exam Format and Structure
Question Types
- Multiple choice - Select one correct answer
- Multiple response - Select all correct answers
- Case studies - Analyze scenarios and answer multiple questions
- Drag and drop - Order steps or match items
- Code analysis - Review and fix code snippets
You'll see actual code snippets in C#, Python, or JavaScript. Be comfortable reading and understanding Azure SDK code.

Development Best Practices
Code-Level Tips
- 1 Use Azure SDK consistently - Know the NuGet packages, npm modules, or pip packages for your language
- 2 Implement retry policies - Use Polly or built-in retry mechanisms
- 3 Leverage async/await - All Azure SDK calls should be asynchronous
- 4 Secure credentials - Never hardcode; use Key Vault and managed identities
- 5 Log strategically - Use Application Insights for structured logging
Exam-Specific Tips
- 1 Know the code - You'll see C#, Python, or JavaScript code snippets
- 2 Understand error handling - Questions test proper exception handling
- 3 SDK versions matter - Focus on latest SDK patterns
- 4 Configuration over code - Prefer app settings to hardcoded values
- 5 Security first - Always choose the most secure option
Practice Questions
Test your Azure development skills with realistic coding scenarios and SDK questions.
Practice with code-based questions and scenario analysis.
Frequently Asked Questions
The exam includes code examples in C#, Python, and JavaScript. You don't need to know all three, but familiarity with at least one is essential.
No, but you need to understand Azure SDK patterns, authentication flows, and common coding scenarios.
Not required, but recommended for those new to Azure. Developers with cloud experience can start with AZ-204.
Very practical. Questions focus on real development scenarios, SDK usage, and implementation details.
No, you must understand SDK code, CLI commands, and Infrastructure as Code. Portal knowledge alone isn't sufficient.
For experienced developers: 4-6 weeks. For those new to cloud development: 8-12 weeks.
Visual Studio Code with Azure extensions is recommended, but any IDE works for practice.
