Question 1

What is the purpose of a CI/CD pipeline in Azure DevOps?

Accepted Answer

CI/CD pipelines automate the process of building, testing, and deploying code, ensuring faster and more reliable software delivery.

Question 2

How do Azure Repos differ from GitHub?

Accepted Answer

Azure Repos is a set of version control tools for managing code, tightly integrated with Azure DevOps, while GitHub is a broader open-source platform.

Question 3

What is the difference between Microsoft-hosted and self-hosted agents?

Accepted Answer

Microsoft-hosted agents are provided and maintained by Microsoft with pre-installed tools. Self-hosted agents are maintained by you and provide more customization.

Question 4

What are Azure Boards used for?

Accepted Answer

Azure Boards help teams plan, track, and discuss work across the development lifecycle using work items, backlogs, Kanban boards, and dashboards.

Question 5

How is YAML used in Azure DevOps Pipelines?

Accepted Answer

YAML defines build and release pipelines as code, allowing versioning, reusability, and better DevOps practices.

Question 6

What are the differences between build and release pipelines?

Accepted Answer

Build pipelines compile and test code, producing artifacts. Release pipelines deploy those artifacts to environments. They can be combined in multi-stage YAML pipelines.

Question 7

How do you implement canary deployments in Azure DevOps?

Accepted Answer

Canary deployments can be achieved using deployment slots in Azure App Service, traffic managers, or by using stages with manual intervention and gradual percentage routing.

Question 8

What is a trigger in Azure Pipelines?

Accepted Answer

Triggers define when a pipeline runs. Common triggers include CI (on commit), PR (pull request), and scheduled triggers. YAML pipelines support these directly.

Question 9

Explain branching strategies used in Azure Repos.

Accepted Answer

Common strategies: Git Flow (develop, feature, release, hotfix), GitHub Flow (short-lived feature branches), and trunk-based development (small frequent commits to main).

Question 10

What is a pull request and how does it integrate with Azure Pipelines?

Accepted Answer

A pull request is a request to merge changes from one branch to another. Azure Pipelines can run PR validation builds to ensure code quality before merging.
