ℹ️

Scoring method: Microsoft reports results on a scaled score from 1 to 1,000, and 700 or greater is required to pass; the scaled score is not a percentage of questions answered correctly, and items may carry different weights. Microsoft does not publish the split of scored and unscored items. Results are normally shown when the exam ends, with a score report showing performance by skill area; beta exam results are released later.. The exam may include unscored pilot questions - treat every question seriously.

Tips to pass Designing and Implementing Microsoft DevOps Solutions (AZ-400) on your first attempt

Practical advice for applying what you know, managing questions and preparing for exam conditions.

🗓

Build and release pipelines are 50-55% of AZ-400 - more than all other domains combined - so weight your study time accordingly.

🔍

Practise the same scenarios in both GitHub Actions and Azure Pipelines YAML, including triggers, templates, environments and approvals.

⏭

Know the security toolchain: GitHub Advanced Security, Dependabot, Defender for Cloud DevOps security and workload identity federation.

📊

Passing AZ-400 alone does not award DevOps Engineer Expert; you also need the Azure Administrator (AZ-104) or Azure Developer (AZ-204) associate.

🔁

You need 700 on a 1-1,000 scaled score; expect case studies and manage time across the 100-minute exam.
