Azure DevOps Interview Questions and Answers for internship

1. What is Azure DevOps?

   • Answer: Azure DevOps is a comprehensive platform providing services for teams to plan, develop, and deploy software. It includes tools for source control (Git), work item tracking (Agile boards), continuous integration/continuous delivery (CI/CD), testing, and monitoring.

2. What are the key services offered by Azure DevOps?

   • Answer: Key services include Azure Repos (Git repositories), Azure Boards (work tracking), Azure Pipelines (CI/CD), Azure Test Plans (testing), and Azure Artifacts (package management).

3. Explain the difference between Git and Azure Repos.

   • Answer: Git is a distributed version control system. Azure Repos is a cloud-hosted service that provides Git repositories, offering features like code management, collaboration, and integration with other Azure DevOps services.

4. How do you create a new Git repository in Azure Repos?

   • Answer: Navigate to your Azure DevOps project, select Repos, and then click "New repository." You can choose to initialize it with a README file.

5. What are branches in Git, and why are they important?

   • Answer: Branches are parallel versions of your codebase. They allow developers to work on new features or bug fixes independently without affecting the main codebase (usually the `main` or `master` branch). This improves collaboration and reduces the risk of introducing errors.

6. Explain the Git workflow (e.g., branching, merging, pull requests).

   • Answer: A typical workflow involves creating a branch for a new feature, making changes, committing those changes, creating a pull request to merge the branch into the main branch, and then merging after code review and approval.

7. What is a pull request in Azure Repos?

   • Answer: A pull request is a mechanism to propose changes from one branch (e.g., a feature branch) to another (e.g., the main branch). It allows for code review and collaboration before merging the changes.

8. How do you resolve merge conflicts in Git?

   • Answer: When merge conflicts occur, Git highlights the conflicting sections in the code. You manually edit the code to resolve the conflict, stage the changes, and then commit the resolution.

9. What are Azure Boards and how are they used for Agile project management?

   • Answer: Azure Boards provides tools for planning and tracking work using Agile methodologies like Scrum and Kanban. You can create boards, add work items (user stories, tasks, bugs), assign them to team members, and track their progress.

10. Explain the difference between Scrum and Kanban in Azure Boards.

    • Answer: Scrum is an iterative framework with sprints (time-boxed iterations), while Kanban is a flow-based system focusing on visualizing and limiting work in progress. Azure Boards supports both methodologies through different board types.

11. What are work item types in Azure Boards?

    • Answer: Common work item types include User Stories, Tasks, Bugs, Issues, and Epic. Each represents a different type of work in a project.

12. How do you create a new work item in Azure Boards?

    • Answer: Navigate to your Azure DevOps project, select Boards, and then choose the appropriate board. Click "New item" to create a new work item of the desired type.

13. What is Azure Pipelines and its role in CI/CD?

    • Answer: Azure Pipelines is a CI/CD service that automates the process of building, testing, and deploying software. It integrates with Azure Repos and other services to create automated workflows.

14. Explain the concept of Continuous Integration (CI).

    • Answer: CI is the practice of frequently integrating code changes into a central repository. Each integration is then verified by an automated build and test process. This helps to detect and address integration issues early.

15. Explain the concept of Continuous Delivery (CD).

    • Answer: CD extends CI by automatically deploying code changes to a staging or production environment after successful integration and testing. It aims to shorten the software release cycle.

16. What is a build pipeline in Azure Pipelines?

    • Answer: A build pipeline defines the steps required to build your application from source code. This typically involves compiling code, running tests, and packaging the application.

17. What is a release pipeline in Azure Pipelines?

    • Answer: A release pipeline defines the steps required to deploy your application to different environments (e.g., development, testing, production). It often includes tasks for deploying to servers, configuring databases, and running post-deployment tests.

18. What are YAML pipelines in Azure Pipelines?

    • Answer: YAML pipelines allow you to define your CI/CD pipelines using YAML code, making them version-controlled and easier to manage.

19. How do you configure a simple CI/CD pipeline in Azure Pipelines?

    • Answer: You would create a new pipeline in Azure Pipelines, connect it to your Git repository, select a template or define your own steps (e.g., build, test, deploy), specify the target environment, and trigger the pipeline on code changes.

20. What are build agents in Azure Pipelines?

    • Answer: Build agents are machines that execute the tasks defined in your pipeline. They can be hosted in the cloud or self-hosted.

21. What are Azure Test Plans and how are they used for testing?

    • Answer: Azure Test Plans provides tools for planning, authoring, managing, and executing tests. You can create test plans, test suites, and test cases, and then execute tests manually or automatically.

22. What are different testing types supported by Azure Test Plans?

    • Answer: Azure Test Plans supports various testing types, including manual testing, exploratory testing, and automated testing.

23. What is Azure Artifacts and how is it used?

    • Answer: Azure Artifacts is a package management service that allows you to share and consume packages (NuGet, npm, Maven, etc.) within your team or organization. It facilitates dependency management and efficient package distribution.

24. How do you integrate Azure DevOps with other services (e.g., GitHub, Jira)?

    • Answer: Azure DevOps offers integrations with many services through extensions and APIs. Specific integration methods vary depending on the service, but often involve connecting accounts or using service hooks.

25. What are service hooks in Azure DevOps?

    • Answer: Service hooks are mechanisms that trigger events in other services based on events within Azure DevOps (e.g., a new build completion triggers a notification in Slack).

26. How do you manage users and permissions in Azure DevOps?

    • Answer: You can manage users and permissions through the Azure DevOps project settings. You can add users, assign them to groups, and define their access levels (e.g., basic, stakeholder, contributor).

27. What is Azure DevOps Server (formerly TFS)?

    • Answer: Azure DevOps Server is an on-premises version of Azure DevOps. It provides similar functionality but is installed and managed within your own infrastructure rather than in the cloud.

28. What is the difference between Azure DevOps and GitHub?

    • Answer: GitHub primarily focuses on Git repositories and collaboration around code, while Azure DevOps offers a broader platform encompassing source control, work item tracking, CI/CD, testing, and other development lifecycle management tools.

29. What are some best practices for using Azure DevOps?

    • Answer: Best practices include using a well-defined branching strategy, automating as much as possible through CI/CD, employing code reviews, using appropriate testing strategies, and regularly monitoring and improving your processes.

30. How do you monitor the performance of your CI/CD pipelines?

    • Answer: Azure Pipelines provides dashboards and logs to track pipeline execution time, success rates, and identify bottlenecks. You can also integrate with monitoring tools for more comprehensive analysis.
