🚀 Introduction: Why Azure DevOps Is a Must-Know in 2025
With Microsoft Azure becoming the second-largest cloud provider globally, companies are rapidly adopting Azure DevOps for managing end-to-end software delivery. Whether you’re preparing for a role in DevOps, SRE, or cloud automation, understanding Azure DevOps tools is critical to acing your next interview.
Here are the top 30 Azure DevOps interview questions and answers for 2025, complete with hands-on YAML pipeline examples and real-world scenarios.

1. What is Azure DevOps?
Azure DevOps is a SaaS-based DevOps platform from Microsoft that provides tools for:
- Source control: Azure Repos
- CI/CD: Azure Pipelines
- Agile project management: Azure Boards
- Artifact management: Azure Artifacts
- Testing: Azure Test Plans
2. What services are included in Azure DevOps?
- Azure Repos – Git-based version control
- Azure Pipelines – CI/CD automation
- Azure Boards – Agile work tracking
- Azure Artifacts – Package hosting
- Azure Test Plans – Manual/exploratory testing
3. What is the difference between classic and YAML pipelines?
| Classic Pipelines | YAML Pipelines |
|---|---|
| GUI-based | Code-based |
| Less portable | Version-controlled and reusable |
4. How do you organize work with Azure Boards?
- Work Items: Epics, Features, Stories, Tasks, Bugs
- Views: Kanban, Sprint Boards
- Tracking: Dashboards, Queries
5. What is a build pipeline vs. release pipeline?
- Build Pipeline: Compiles and tests code
- Release Pipeline: Deploys to environments
✅ Modern practice: Combine both using multi-stage YAML pipelines
⚙️ Section 2: Azure CI/CD Interview Questions (YAML + Examples)
6. How do you create a YAML pipeline in Azure DevOps?
- Navigate to Pipelines > New Pipeline
- Choose your Git repo

inputs:
versionSpec: '18.x'
displayName: 'Install Node.js'
- script: npm install
displayName: 'Install dependencies'
- script: npm test
displayName: 'Run tests'
8. How do you use variables in Azure Pipelines?

- Use AzureKeyVault@2 task
- Use secret variables in variable groups
- Mask sensitive values in logs
12. How do you troubleshoot a failing Azure pipeline?
- Check error logs in Jobs and Steps
- Set
System.Debug: truefor verbose output - Clean checkout and retry
- Validate service connections
13. What is a service connection in Azure Pipelines?
Used to authenticate with:
- Azure Subscriptions
- GitHub
- Docker Hub
- Kubernetes clusters
14. What is an agent pool?
A logical grouping of build agents (Microsoft-hosted or self-hosted) that run your pipeline jobs.
15. What is a deployment group?
A collection of target machines for agent-based deployments (e.g., to on-prem servers).
📦 Section 4: Scenario-Based Azure DevOps Interview Questions
16. How would you set up CI/CD for a microservices project?

appName: 'my-app-service'
package: '$(System.DefaultWorkingDirectory)/**/*.zip'
18. How do you implement canary deployment?
- Use deployment slots
- Route traffic using Azure Front Door
- Monitor and auto-promote on success
19. How do you roll back a failed deployment?
- Re-deploy last good artifact
- Use approval gates
- Add manual intervention tasks in YAML
20. How do you manage pipeline environments?
- Use environment-based parameters
- Define variable groups per env
- Use checks and approvals for prod
🔄 Section 5: Azure DevOps Integration and Ecosystem
21. How do you integrate Azure DevOps with GitHub?
- Connect GitHub as a repo source
- Use
checkout: selforgit://syntax - Install Azure Pipelines GitHub App
22. How do you integrate testing into pipelines?
