1. What is Azure DevOps?

Azure DevOps is a set of tools from Microsoft that helps teams manage the software development process. It supports planning, coding, testing, deployment, and monitoring in one place. Azure DevOps is very useful for teams.

2. Name the five core services of Azure DevOps.

Azure DevOps offers five services that support development work. These services are:

• Azure Boards – Helps track tasks and manage projects.
• Azure Repos – Used to store and manage source code.
• Azure Pipelines – Automates build and deployment (CI/CD).
• Azure Test Plans – Allows both manual and automated testing.
• Azure Artifacts – Manages packages and dependencies.

3. Explain the differences between Azure DevOps Services and Azure DevOps Server.

Azure DevOps comes in two versions. One version is on the cloud called Services. Microsoft manages it so you do not need to set it up. The other version is called Server. You install it on your system. It provides more control but also needs regular maintenance.

4. Explain CI/CD in the context of Azure DevOps.

CI/CD is an important DevOps practice:

• Continuous Integration (CI) – Automatically builds and tests code whenever changes are made.
• Continuous Delivery (CD) – Automatically deploys code to production or staging environments.
• Azure Pipelines helps automate this entire process

5. What are Azure Boards used for?

Azure Boards are used to plan, track, and manage work on a project. Teams can use boards and dashboards to organize tasks, see how things are going, and work together. This helps teams get things done.

6. What is the purpose of Work Items in Azure Boards?

Work Items represent different types of tasks in a project:

• Epics – Large features or goals.
• Features – Smaller parts of epics.
• User Stories – Requirements from a user perspective.
• Tasks – Small units of work.
• Bugs – Issues that need fixing.

7. How does Azure DevOps support Agile methodology?

Azure DevOps supports Agile with to-use templates. These templates are for Scrum and Agile. They help teams work in sprints. You can track progress. Deliver work step by step. Azure DevOps makes Agile easy to use.

8. What is Azure Repos?

Azure Repos is a version control system. It helps teams store and manage code. Azure Repos supports Git and TFVC. Git is a distributed system used for version control. TFVC is a version control system. Azure Repos helps teams manage their code.

9. What are Pull Requests (PRs) and why are they important?

Pull Requests help review and merge code changes:

• Allows code review by team members before merging changes.
• Help maintain code quality.
• Encourage collaboration and discussion.
• Reduce errors in the final code.

10. What are Branch Policies in Azure Repos?

Branch policies are rules applied to important branches:

• Require code reviews before merging.
• Ensure successful builds before changes are accepted.
• Protect the main or production branches from errors.

11. What is a YAML pipeline?

A YAML pipeline is a simple text file used to define build and deployment steps:

• Written in a human-readable format.
• Stored along with the code.
• Makes pipelines easy to manage and version.

12. What are Pipeline Agents?

Pipeline agents are systems that run pipeline tasks:

• Can be Microsoft-hosted (managed by Azure).
• Or self-hosted (managed by your team).
• Responsible for executing build and deployment jobs.

13. What is the purpose of an artifact in Azure DevOps?

An artifact, in Azure DevOps, is what you get at the end of a build process. It can be a file, a package, or a whole application that is ready to use or share. Azure DevOps and artifacts are closely related because artifacts are the result of the work that teams do using Azure DevOps.

14. What is Infrastructure as Code (IaC)?

Infrastructure as Code allows you to manage and set up infrastructure using code instead of manual steps:

• Uses templates like ARM or Terraform.
• Makes deployment faster and consistent.
• Reduces human errors.

15. What is “Shift Left” in DevOps?

Shift Left is the practice of performing testing and security earlier in development to:

• Identify issues early.
• Improve software quality.
• Save time and cost by fixing problems sooner.

Azure DevOps Interview Questions for Experienced Candidates

1. How do you implement “Shift Left” security (DevSecOps) in an Azure Pipeline?

Shift Left security means adding security checks

Here are some steps:

• Add security checks during planning and development stages.
• Use tools like Snyk for dependency scanning.
• Use SonarQube for code analysis during builds.
• Store secrets securely using Azure Key Vault.

2. What is a Multi-stage Pipeline, and why is it beneficial?

A multi-stage pipeline helps manage build, test, and deployment in one YAML file.

• Defines stages like Development, QA, and Production.
• Provides a clear view of deployment progress.
• Supports approvals and checks between stages.
• Improves control and governance.

3. Differentiate between Microsoft-hosted and Self-hosted Agents.

Azure Pipelines uses agents to run tasks. There are two types:

• Microsoft-hosted agents
  • Managed by Microsoft.
  • Provide a fresh virtual machine for every job.
  • Limited control over installed tools.
• Self-hosted agents
  • Managed by your team.
  • Full control over the environment.
  • Faster builds due to caching.

4. How would you handle a failed deployment in a production environment?

Handling failure quickly is important to reduce impact.

• Immediate Action
  • Check logs and monitoring tools like Azure Monitor.
  • Identify the root cause.
• Resolution
  • Roll back to the last stable version.
  • Use Blue/Green deployment to switch traffic back safely.

5. What are Deployment Groups vs. Variable Groups?

These are used for different purposes in Azure DevOps:

• Deployment Groups
  • Group of target machines (VMs or physical servers).
  • Used for deploying applications.
• Variable Groups
  • Collection of variables shared across pipelines.
  • Can be linked to Azure Key Vault for secrets.

6. How do you optimize a CI/CD pipeline for faster build times?

Improving pipeline speed helps teams deliver faster.

• Run parallel jobs to execute tasks at the same time.
• Use build caching to avoid downloading dependencies repeatedly.
• Enable incremental builds to compile only changed code.

7. What is the “Forking Workflow” and when is it used?

The forking workflow is widely adopted in open-source projects.

• Create a copy (fork) of a repository.
• Make changes safely without affecting the original code.
• Submit changes using Pull Requests after testing.
• Useful for collaboration and experimentation.

8. Explain Blue/Green vs. Canary deployment strategies.

These are two common deployment methods:

• Blue/Green Deployment
  • Two identical environments (Blue and Green).
  • Switch all traffic to the new version once tested.
• Canary Deployment
  • Release updates to a small group of users first.
  • Gradually increase traffic after testing.

9. How does Azure DevOps integrate with Kubernetes (AKS)?
