Azure DevOps Interview Questions and Answers for 7 years experience

1. What are the key differences between Azure DevOps Server and Azure DevOps Services?

   • Answer: Azure DevOps Server is an on-premises solution, offering more control and customization but requiring dedicated infrastructure management. Azure DevOps Services is a cloud-based SaaS offering, providing ease of use, scalability, and automatic updates, but with less control over the underlying infrastructure. Key differences also include licensing costs, update frequency, and access control management.

2. Explain the different Azure DevOps services and their purpose.

   • Answer: Azure DevOps offers several integrated services: Azure Boards (work item tracking), Azure Repos (Git repository management), Azure Pipelines (CI/CD), Azure Test Plans (test management), and Azure Artifacts (package management). Each service plays a crucial role in the software development lifecycle (SDLC), enabling teams to plan, develop, test, and deploy software efficiently.

3. Describe your experience with Azure Boards and how you've used it to manage complex projects.

   • Answer: [This answer should be tailored to your experience. Example: "I've extensively used Azure Boards to manage projects using Scrum and Kanban methodologies. I've defined custom work item types, created dashboards visualizing progress, and implemented custom workflows to suit project needs. For complex projects, I leveraged area paths and iterations to organize work, used queries to track progress and identify bottlenecks, and integrated Azure Boards with other DevOps services for seamless workflow."]

4. How do you handle branching strategies in Azure Repos? Explain your preferred strategy and why.

   • Answer: [This answer should be tailored to your experience. Example: "I typically use a Gitflow branching strategy, combining a main branch for production releases with feature branches for new development and release branches for preparing releases. This approach promotes code stability, allows for parallel development, and simplifies the integration process. Other strategies like GitHub Flow or GitLab Flow can also be effective depending on the project’s needs."]

5. Explain your experience with Azure Pipelines and how you've implemented CI/CD.

   • Answer: [This answer should be tailored to your experience. Example: "I have extensive experience setting up and maintaining CI/CD pipelines using Azure Pipelines.
