Top 50 Azure DevOps Interview Questions and Answers

Q1. What is Azure DevOps?

Answer: Azure DevOps is a Microsoft cloud platform offering a suite of tools for planning, developing, testing, and delivering software, including Boards, Repos, Pipelines, Artifacts, and Test Plans.

Q2. What are the core services in Azure DevOps?

Answer: Azure Boards (work tracking), Azure Repos (source control), Azure Pipelines (CI/CD), Azure Artifacts (package management), and Azure Test Plans (manual and exploratory testing).

Q3. What is the difference between Azure DevOps Server and Azure DevOps Services?

Answer: Azure DevOps Services is the cloud-hosted (SaaS) version managed by Microsoft, while Azure DevOps Server is an on-premises version installed and maintained by the organization.

Q4. What is a Project in Azure DevOps?

Answer: A Project is a container that groups related work items, repositories, pipelines, and artifacts for a specific product or team, providing a boundary for permissions and configuration.

Q5. What is Azure Boards used for?

Answer: Azure Boards is used for agile project management — tracking work items such as user stories, tasks, bugs, and epics, and visualizing progress through Kanban boards and sprint backlogs.

Q6. What are work item types in Azure Boards?

Answer: Common work item types include Epics, Features, User Stories (or Backlog Items), Tasks, and Bugs, organized in a hierarchy depending on the selected process template (Agile, Scrum, or CMMI).

Q7. What is a sprint in Azure Boards?

Answer: A sprint is a fixed time-boxed iteration (commonly one to four weeks) during which a team commits to completing a defined set of backlog items, tracked using a sprint backlog and burndown chart.

Q8. What is Azure Repos?

Answer: Azure Repos provides Git repositories (or optionally Team Foundation Version Control) for source code management, including branching, pull requests, and code reviews.

Q9. What is a pull request in Azure Repos?

Answer: A pull request is a request to merge changes from one branch into another, typically reviewed by teammates, validated by automated build policies, before being merged.

Q10. What are branch policies?

Answer: Branch policies enforce rules on a branch, such as requiring a minimum number of reviewers, passing builds, or linked work items before a pull request can be completed.

Q11. What is Azure Pipelines?

Answer: Azure Pipelines is Azure DevOps's CI/CD service, used to automatically build, test, and deploy code to various environments and cloud platforms.

Q12. What is the difference between a build pipeline and a release pipeline?

Answer: A build pipeline (CI) compiles code, runs tests, and produces artifacts, while a release pipeline (CD) takes those artifacts and deploys them across environments like dev, staging, and production.

Q13. What is a YAML pipeline?

Answer: A YAML pipeline defines build and release steps as code in a azure-pipelines.yml file stored in the repository, enabling version control, code review, and reuse of pipeline definitions.

Q14. What is a pipeline agent?

Answer: An agent is a machine (Microsoft-hosted or self-hosted) that runs the jobs defined in a pipeline, executing tasks such as building, testing, and deploying code.

Q15. What are stages, jobs, and tasks in a pipeline?

Answer: A pipeline is made up of stages (major divisions like Build and Deploy), which contain jobs (units of work run on an agent), which in turn contain tasks (individual steps like restoring packages or running tests).

Q16. What is Azure Artifacts used for?

Answer: Azure Artifacts is a package management service for hosting and sharing packages such as NuGet, npm, Maven, and Python packages across teams and pipelines.

Q17. What is a feed in Azure Artifacts?

Answer: A feed is a container for organizing and controlling access to packages, allowing teams to publish and consume packages privately or share them across the organization.

Q18. What is Azure Test Plans used for?

Answer: Azure Test Plans is used for planning, executing, and tracking manual, exploratory, and user acceptance testing, complementing automated testing done within Azure Pipelines.

Q19. How does Azure DevOps integrate with Docker and Kubernetes?

Answer: Azure Pipelines can build Docker images, push them to a container registry, and deploy them to Kubernetes clusters using built-in tasks, enabling full CI/CD for containerized applications.

Q20. What is the difference between Azure DevOps and GitHub Actions?

Answer: Both provide CI/CD capabilities, but Azure DevOps offers a broader integrated suite (Boards, Repos, Artifacts, Test Plans) in one platform, while GitHub Actions is tightly integrated with GitHub repositories and workflows defined directly alongside the code.
