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 6weighted 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 Design and implement build and release pipelines and Configure processes and communications contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
AZ-400 Exam Blueprint — 6 Domains
Design and implement source control
Configure processes and communications
Develop a security and compliance plan
Implement an instrumentation strategy
Design and implement build and release pipelines
Design and implement a source control strategy
49 numbered sets, 6 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 696+ 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 6 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.
A team uses a monorepo in Azure Repos. They want to implement a build validation policy that only triggers builds for code changes in specific folders to reduce build times. Which approach should they use?

Your organization uses Azure DevOps for a multi-tier web application. The application consists of a React frontend, a Node.js API, and a SQL database. The security team has mandated the following: (1) All code changes must be scanned for secrets before merging to the main branch. (2) Infrastructure-as-code templates (ARM) must be validated for security compliance before deployment. (3) Production deployments must use a service connection with a managed identity that has only the required permissions. You have set up a CI/CD pipeline with two stages: Build and Release. The Build stage runs on pull requests and the Release stage deploys to a production environment. Recently, a developer accidentally committed a secret (API key) to a configuration file. The secret was not caught by the pipeline, and the code was merged to main. You need to prevent this in the future. What should you do?
Select an answer to reveal the explanation
Your organization uses Azure DevOps to manage CI/CD pipelines. The security team requires that all pipeline runs use a specific service connection that references a managed identity in Microsoft Entra ID. However, some developers have been using personal access tokens (PATs) in their pipelines, bypassing the managed identity. What should you implement to enforce the use of the managed identity service connection?

You are designing a release pipeline that deploys to multiple environments (dev, test, prod) with approval gates between each. You need to ensure that the same build artifact is deployed to all environments. Which strategy should you use?
Select an answer to reveal the explanation
Your release pipeline deploys to multiple environments (Dev, Test, Prod) using approval gates. Recently, the Prod deployment failed because a manual validation task timed out after 30 minutes. You need to ensure that if the manual validation is not approved within 15 minutes, the pipeline automatically rejects the deployment and sends a notification. What should you do?

Your organization uses GitHub Actions for CI/CD. You need to ensure that deployment to production only occurs after a successful deployment to a staging environment and requires approval from a senior developer. The deployment workflow is defined in a single YAML file. What is the most efficient way to achieve this?
Select an answer to reveal the explanation
Your team is designing a build pipeline for a Java application that uses Maven. The pipeline must run unit tests and integration tests separately, and fail the build if integration tests fail. However, integration tests require a running database container. Which approach should you use to ensure the database is available for the integration tests?

Answer all 20 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 6 domains: Design and implement source control (7%), Configure processes and communications (13%), Develop a security and compliance plan (13%), Implement an instrumentation strategy (7%), Design and implement build and release pipelines (54%), Design and implement a source control strategy (6%). Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Design and implement build and release pipelines and Configure processes and communications — 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 original — AI-assisted, checked against the official exam objectives, and published under the editorial oversight of an engineer with 12+ years' experience. They test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
