Azure Devops Interview Questions Set 01

1. What is DevOps?

DevOps is a methodology aimed at enhancing work efficiency throughout the software development lifecycle. It’s like an ongoing cycle emphasizing communication, collaboration, and integration. DevOps combines software development (Dev) and operations (Ops) to streamline the software delivery process. It’s more than just practices and tools; it’s a cultural philosophy focusing on automating and integrating functions between development and IT teams. DevOps fosters faster and more efficient software delivery by emphasizing communication, collaboration, and integration between teams.

2. What are the key components of Azure DevOps? 

Azure DevOps comprises several crucial components that facilitate collaboration, automate workflows, and streamline software delivery. Here’s an overview of the key components:

Azure Boards

Azure Boards serves as the core project management tool, offering teams a flexible work tracking system. It enables planning, tracking, and discussions across the development process.

Azure Repos

Azure Repos is a version control system designed to efficiently manage and track changes to codebases. Supporting both centralized and distributed version control systems like Git, it ensures compatibility with various development workflows.

Azure Pipelines

Azure Pipelines automates build, test, and deployment processes, playing a vital role in DevOps practices. It supports continuous integration and continuous delivery (CI/CD) pipelines, allowing teams to automate the entire software delivery lifecycle.

Azure Test Plans

Azure Test Plans provide comprehensive testing capabilities, aiding teams in delivering high-quality software. It facilitates test planning, tracking, and coordination, ensuring thorough test coverage and timely issue resolution.

Azure Artifacts

Azure Artifacts offers a centralized package management system, simplifying the management and distribution of code dependencies. It allows teams to create, host, and share packages seamlessly across projects and teams.

3. Why is DevOps important?

 DevOps is crucial because it facilitates shorter development cycles, faster innovation, reduced deployment failures, improved communication and collaboration, and easier application maintenance. By leveraging automation and accelerated processes, DevOps teams enhance reliability and increase deployment frequency. The primary goal of adopting DevOps is to streamline the software development process, making it faster, more efficient, and more secure. Its benefits include continuous software delivery, improved team collaboration, simplified deployment, enhanced efficiency and scalability, and strengthened application security.

4. How does DevOps function? 

DevOps operates as a set of practices, tools, and cultural principles that automate and integrate processes between software development and IT teams. It emphasizes team empowerment, cross-functional communication, collaboration, and automation. Often, development and operations teams merge into a single unit, where engineers work across the entire application lifecycle, possessing a variety of skills. Tools are used to automate processes, enhancing reliability and efficiency. A DevOps toolchain encompasses essential DevOps principles like continuous integration, continuous delivery, automation, and collaboration. DevOps values extend beyond development teams; when applied to security, for example, it becomes DevSecOps, integrating security seamlessly into the development process.

5. What are Forks in Azure DevOps?

Picture having a delectable slice of cake in front of you. Now, someone takes a fork and delicately separates a piece that mirrors the original slice. That’s essentially what a fork does in Azure DevOps. A fork in Azure DevOps is a complete replica of a repository, containing all files, commits, and branches. It functions independently from the original repository, and changes made in one do not automatically reflect in the other. To share changes, developers can use pull requests to propose and merge their modifications back to the original repository. Forks facilitate parallel development, allowing multiple developers to work on a project simultaneously without disrupting each other. It encourages collaboration, experimentation, and thorough code review before integrating changes into the main repository.

6. What is Azure DevOps?

Azure DevOps is a Microsoft service built on the Azure cloud platform, offering a comprehensive set of tools to manage the entire software development lifecycle. It provides integrated features accessible via web browsers or IDE clients and supports Agile methodologies, source control, build and release services, and application insights.

7. What are the advantages of DevOps?

 DevOps brings numerous benefits, including accelerated feature delivery, more reliable operating environments, enhanced communication and collaboration, increased innovation time, improved customer satisfaction, agility, quality, and security, along with a competitive edge. DevOps also boosts efficiency through automation, optimizes business processes, enhances software development and deployment speed and stability, and refocuses on customer needs.

8. Azure DevOps offers three main access levels:

1. Stakeholder Access: Provides free access for an unlimited number of users to collaborate on projects with restricted features.
2. Basic Access: Offers comprehensive access to features such as source control, work items, build pipelines, and project settings.
