Azure DevOps Interview Questions for Freshers

1. What is Azure DevOps?

Azure DevOps is a Microsoft platform that provides tools for planning, building, testing, and deploying applications. It supports the entire software lifecycle, offering features like version control, CI/CD pipelines, and project management to enhance team collaboration and automate processes.

2. What are the core services of Azure DevOps?

The core services of Azure DevOps include:

• Azure Repos: Provides Git repositories for version control.
• Azure Pipelines: Supports CI/CD pipelines for automating build, test, and deployment.
• Azure Boards: Offers tools for planning, tracking, and managing work items and projects.
• Azure Test Plans: Provides a suite for manual and automated testing.
• Azure Artifacts: Manages packages and dependencies for projects.

3. Explain the concept of version control in Azure DevOps.

Version control in Azure DevOps refers to the practice of managing and tracking changes made to the codebase over time. It allows developers to collaborate effectively and maintain a history of modifications. Azure DevOps provides two main version control systems:

1. Git: A distributed version control system where each developer has a local copy of the entire repository, enabling offline work and efficient collaboration.
2. Team Foundation Version Control (TFVC): A centralized version control system where the code is stored in a central repository, and developers check in changes to it.

Version control helps in tracking changes, collaborating with team members, reverting to previous versions, and resolving conflicts in code.

4. What is a build pipeline in Azure DevOps?

Version control in Azure DevOps refers to the practice of managing and tracking changes made to the codebase over time. It allows developers to collaborate effectively and maintain a history of modifications. Azure DevOps provides two main version control systems:

• Git: A distributed version control system where each developer has a local copy of the entire repository, enabling offline work and efficient collaboration.
• Team Foundation Version Control (TFVC): A centralized version control system where the code is stored in a central repository, and developers check in changes to it.

Version control helps in tracking changes, collaborating with team members, reverting to previous versions, and resolving conflicts in code.

5. How do you create and manage a project in Azure DevOps?

To create and manage a project in Azure DevOps, start by logging into your Azure DevOps account. On the homepage, click on “New Project,” enter a project name, description, and choose visibility (public or private). After creating the project, you can organize it by creating repositories, pipelines, boards, and other resources. You can manage your project by configuring work items, setting up continuous integration/continuous delivery (CI/CD) pipelines, and assigning roles to team members. Azure DevOps provides tools to track progress, collaborate, and integrate with other services to streamline your development process.

6. What are the different types of repositories available in Azure DevOps?

Azure DevOps offers two repository types:

1. Git Repositories: A distributed version control system where each developer has their own copy of the code, supporting branching and offline work.
2. Team Foundation Version Control (TFVC): A centralized version control system where code is stored on a central server, and developers check out and check in files.

7. What are Continuous Integration (CI) and Continuous Deployment (CD)?

Continuous Integration (CI) is the practice of frequently merging code changes into a shared repository, usually multiple times a day. This helps to detect errors early, improve collaboration, and ensure that new code integrates smoothly with the existing codebase.

Continuous Deployment (CD) is the practice of automatically deploying code changes to production after they pass testing. This allows for faster delivery of features, bug fixes, and updates, reducing the time between development and release to end users.

• Portability: YAML files can be reused across different projects.
• DevOps Alignment: Encourages automation and Infrastructure as Code practices.

15. How do you implement parallel and sequential job execution in Azure DevOps pipelines?

In Azure DevOps, you can implement parallel and sequential job execution in pipelines using YAML.

For Sequential Execution:

By default, jobs in Azure DevOps are executed sequentially. Just define jobs in the order you want them to run.

jobs:

  – job: Job1

    steps:

      – task: Task1

  – job: Job2

    dependsOn: Job1

    steps:

      – task: Task2

For Parallel Execution:

To run jobs in parallel, simply list them without the dependsOn clause, allowing them to execute at the same time.

jobs:

  – job: Job1

    steps:

      – task: Task1

  – job: Job2

    steps:

      – task: Task2

In this setup, Job1 and Job2 will run simultaneously. You can also control parallelism by specifying dependencies between jobs.
