Courseiva
This free AZ-400 practice test mirrors the structure and difficulty of the real Microsoft Azure DevOps Engineer Expert AZ-400 exam. Every question is written against the official 2026 exam blueprint published by Microsoft, ensuring you practise exactly what the exam tests — not last year's objectives.
The AZ-400 blueprint is divided into 7weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Configure processes and communications and Design and implement source control contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
AZ-400 Exam Blueprint — 7 Domains
Configure processes and communications
Design and implement source control
Design and implement build and release pipelines
Develop a security and compliance plan
Implement an instrumentation strategy
Design and implement a DevOps infrastructure
Design and implement a source control strategy
60 numbered sets, 7 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass AZ-400 on their first attempt:
Answer before revealing
Read each AZ-400 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which AZ-400 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real AZ-400 gives you roughly 2.4 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass AZ-400 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 913+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 7 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.
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 team uses Azure Pipelines to build a .NET Core application. The build pipeline runs successfully, but the release pipeline fails when deploying to Azure App Service with the error: 'ERROR_FILE_IN_USE'. What is the most likely cause?
Select an answer to reveal the explanation
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?
Select an answer to reveal the explanation
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?
Select an answer to reveal the explanation
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?
Select an answer to reveal the explanation
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
A structured study plan dramatically increases your chances of passing AZ-400 on the first attempt. The most effective approach combines reading the official Microsoft documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for AZ-400 preparation:
Cover each AZ-400 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing AZ-400 score.
On exam day, the AZ-400 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Scaled scoring
The AZ-400 exam uses a scaled scoring system — your raw score of correct answers is converted to a score out of 1000. A passing score of 700/1000 does not mean you need 70% of questions correct; the conversion accounts for question difficulty. Consistently scoring above 75–80% on practice tests puts you in a strong position to achieve 700/1000 on the real exam.

Every question is written against the official AZ-400 exam blueprint published by Microsoft. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass AZ-400 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The AZ-400 covers 7 domains: Configure processes and communications, Design and implement source control, Design and implement build and release pipelines, Develop a security and compliance plan, Implement an instrumentation strategy, Design and implement a DevOps infrastructure, Design and implement a source control strategy. Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Configure processes and communications and Design and implement source control — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Microsoft's authorisation. Using them violates your NDA and Microsoft's certification agreement, and can result in certification revocation. Courseiva questions are 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
Per-domain analytics, spaced repetition, daily challenges — and every other certification on the platform.
