Simulate the real Microsoft Azure DevOps Engineer Expert AZ-400 exam with full-length timed sessions. Questions drawn proportionally from all 7 official blueprint domains — the same mix you'll face on test day.
Simulate real exam conditions
For the most realistic AZ-400 simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (120 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
This free AZ-400 mock exam uses the same question distribution as the real Microsoft Azure DevOps Engineer Expert AZ-400 exam. Each session draws questions proportionally from all 7 official blueprint domains published by Microsoft, so the topic mix you see accurately reflects what you'll face on test day.
AZ-400 Domain Distribution
Configure processes and communications
Design and implement source control
Design and implement build and release pipelines

Every question is written by certified engineers against the 2026 AZ-400 exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your AZ-400 study plan.
Practice test — for learning
Use the AZ-400 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the AZ-400 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

A team uses Azure Boards and wants to ensure that work items moved to the 'Done' state require a completed code review. What should they configure?

A team uses a monorepo with multiple projects in one Git repository. They want to enforce that each commit message must reference a work item from Azure Boards. Which branch policy should they configure?

A company uses Azure DevOps for CI/CD. The security team requires that all pipeline runs must use a specific service connection (ServiceConnection-Prod) that has been approved for production deployments. However, developers are accidentally using unapproved connections. You need to enforce that only the approved service connection can be used in any pipeline that deploys to the production environment. What should you do?

You are configuring Application Insights for a .NET Core web application deployed to Azure App Service. The application must capture telemetry for all HTTP requests, exceptions, and dependency calls with minimal code changes. What should you do?

A team wants to enforce that all Azure resource groups in a subscription are tagged with 'CostCenter' and 'Environment'. They need a solution that automatically applies these tags to any new resource group and ensures compliance without manual intervention. What should they use?

Your team uses a monorepo in Azure Repos with multiple feature branches. You notice that merge conflicts frequently occur because developers are working on the same files. You want to reduce conflicts and improve collaboration. Which branching strategy should you recommend?

Answer all 7 questions to see your domain score breakdown
Sitting the AZ-400 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The AZ-400 exam lasts 120 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most AZ-400 distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Microsoft writes many AZ-400 questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real AZ-400 is a mental marathon lasting 120 minutes. In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina. If you cannot stay focused for 120 minutes in practice, you will struggle on exam day.

Scaled scoring
The AZ-400 uses scaled scoring — your raw percentage correct is converted to a score out of 1000. Consistently scoring above 80% on mock exams puts you well above the 700/1000 threshold, giving you a buffer for any unexpected question types on the real exam.
Yes. Courseiva provides free AZ-400 mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
Aim for consistent scores of 80% or above on full-length AZ-400 mock exams before booking your test date. The official passing score of 700/1000 corresponds to roughly 72–75% correct answers, so an 80% buffer accounts for difficulty variation and question styles on the real exam.
Most candidates who pass AZ-400 on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
No — all Courseiva questions are original, written by certified engineers against public Microsoft exam blueprints. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your Microsoft certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
