Overview
About the exam
The AZ-400 certification validates expertise in designing and implementing DevOps practices for Microsoft Azure. It covers development process design, source control management, CI/CD pipelines with Azure DevOps and GitHub Actions, dependency management, infrastructure as code, continuous feedback, security practices, and compliance automation across the software delivery lifecycle.
This expert-level certification is designed for DevOps engineers, platform engineers, and developers who combine development and operations expertise. Candidates should be proficient with Azure administration and development, with practical experience in Azure DevOps or GitHub for implementing end-to-end DevOps workflows.
Exam Domains
What's on the exam
The exam consists of 40–60 questions to be completed in approximately 100 minutes (100 minutes if labs are included). Question types include multiple-choice, multiple-select, drag-and-drop, hot area, and case study formats. Questions heavily test pipeline YAML syntax, GitHub Actions workflows, and infrastructure as code templates. Expect scenarios requiring you to design complete CI/CD pipelines and select appropriate DevOps tooling.
Design and implement traceability and flow of work (GitHub Flow, feedback cycles, GitHub projects, Azure Boards), design and implement metrics and queries for DevOps, and configure collaboration and communication (wikis, release docs, webhooks, Teams integration)
Design and implement branching strategies (trunk-based, feature branch, release branch, PR workflows, branch policies/protection rules) and configure and manage repositories (large files, Git LFS, scaling, permissions, tags, data recovery)
Design and implement package management (GitHub Packages, Azure Artifacts, versioning), testing strategy (quality/release gates, comprehensive testing, code coverage), pipelines (GitHub Actions, Azure Pipelines, YAML, multi-stage, hybrid), deployments (blue-green, canary, ring, feature flags, database tasks), IaC (ARM, Bicep, Azure Machine Configuration), and pipeline maintenance
Design and implement authentication and authorization (service principals, managed identities, GitHub Apps, service connections, permissions/roles) and manage sensitive information in automation (Key Vault, secrets, workload identity federation, secure files)
Configure monitoring for DevOps environments (Azure Monitor, Application Insights, VM/Container/Storage/Network Insights, GitHub insights) and analyze metrics from instrumentation (infrastructure performance, telemetry, distributed tracing, KQL queries)

What to expect
Watch out
Where candidates struggle
This exam spans both Azure DevOps and GitHub. Candidates who are experienced with only one platform often struggle with questions about the other's specific features and configurations.
- 01YAML Pipeline Syntax — Not knowing Azure Pipelines YAML syntax for stages, jobs, steps, and variable groups including template references.
- 02GitHub vs Azure DevOps — Confusing equivalent features between GitHub Actions and Azure DevOps Pipelines including triggers and approval gates.
- 03IaC Tools — Struggling to differentiate when to use ARM templates, Bicep, Terraform, or Pulumi for infrastructure as code scenarios.
- 04Security Integration — Overlooking DevSecOps practices like SAST/DAST scanning, dependency scanning, and secret management in pipelines.
- 05Monitoring Strategy — Not understanding how to implement continuous feedback loops using Azure Monitor, Application Insights, and dashboards.
