The Microsoft Azure DevOps Engineer Expert (AZ-400) is Microsoft's top credential for DevOps professionals working on the Azure platform. It validates the ability to design and implement DevOps practices for version control, compliance, infrastructure as code, configuration management, continuous integration, continuous delivery, and monitoring.
The exam covers five domains: Configure Processes and Communications (10–15%), Design and Implement Source Control (15–20%), Design and Implement Build and Release Pipelines (40–45%), Develop a Security and Compliance Plan (10–15%), and Implement an Instrumentation Strategy (10–15%). Core tools and services include Azure DevOps (Boards, Repos, Pipelines, Artifacts), GitHub and GitHub Actions, Azure Container Registry, Azure Kubernetes Service, Azure Bicep and ARM templates, Azure Key Vault, and Azure Monitor.
The AZ-400 requires passing either the AZ-104 or AZ-204 as a prerequisite. It is highly valued by DevOps engineers, release managers, and platform engineers who design automation and delivery pipelines for Azure workloads and want a recognized credential beyond platform-specific experience.
“Passed AZ-400 well. The DevOps process and CI/CD questions were realistic, and the custom sessions let me drill what I was weakest on.”
“Covers every objective. Explanations are clear and actionable. Sitting it under real conditions beforehand is what made the day feel routine.”
Every AZ-400 question is written by someone who holds this certification and works in the field — not scraped from other sites, and not generated and shipped unreviewed. Every explanation you are shown has been read and approved by that same expert first.
DevOps engineers, release managers, and platform engineers implementing CI/CD and automation for Azure workloads.
