About AZ-400

DevOps with Azure DevOps and GitHub: work tracking, branching and pull request policy, YAML pipelines and release strategies, package management, secrets and compliance scanning, and observability.

Who it's for. DevOps engineers. Microsoft expects AZ-104 or AZ-204 experience first.

How to prepare

  • Pipelines are over half of the bank. Know stages, jobs, templates, environments and approvals in YAML.
  • Know the branching strategies (trunk-based, GitFlow, release branches) and when each fits.
  • Secrets go in Key Vault or variable groups linked to Key Vault, never in YAML.

Questions people ask

Is this AZ-400 practice exam free?

Yes. All 266 questions, the timed mock exam and the explanations are free, and there's no account to create.

Are these real exam questions?

No. Real exam questions are confidential under the Azure candidate agreement. These are practice questions written to cover the same domains in the same scenario style, each with an explanation of why the answer is right.

How is the AZ-400 mock exam scored?

Questions are drawn from every domain in proportion to the exam guide, and you get a raw percentage with a breakdown by domain. Azure uses scaled scoring, so treat 75% or more here as a sign you're ready rather than a predicted score.
