Certification Requirements

To earn the AZ DevOps Engineer Expert certification, you need:

1. Pass AZ-104 OR AZ-204: One of these associate-level certifications is mandatory
2. Pass AZ-400: The DevOps Engineer Expert exam

Which Prerequisite Should You Choose?

Choose AZ-104 (Administrator) if:

• You have a background in system administration or IT operations
• You work primarily with infrastructure and networking
• You want to specialize in infrastructure automation and IaC
• Your role involves managing AZ subscriptions and resources

Choose AZ-204 (Developer) if:

• You have a software development background
• You work primarily with application code and APIs
• You want to focus on CI/CD pipelines and application deployment

Key Skills for DevOps Engineers

The AZ-400 exam covers a comprehensive set of DevOps skills. Mastering these areas prepares you for both the certification and real-world DevOps challenges.

1. Continuous Integration and Continuous Delivery (CI/CD)

CI/CD forms the backbone of modern software delivery. You need to understand:

• Designing and implementing build pipelines
• Creating release pipelines with multiple stages and environments
• Implementing deployment patterns (blue-green, canary, rolling)
• Managing pipeline artifacts and dependencies
• Automating testing within pipelines

2. Infrastructure as Code (IaC)

Managing infrastructure through code enables consistency and repeatability:

• ARM templates and Bicep for AZ resources
• Terraform for multi-cloud infrastructure
• Desired State Configuration (DSC)
