200-901 Question 18

Select 3

As a DevOps engineer at a software company, you are collaborating with a team of developers on a new API project. The team needs a system that allows them to track changes to their codebase, resolve merge conflicts when multiple developers work on the same files, and maintain a history of all changes for debugging purposes. Which of the following are advantages of using a version control system (VCS) in this scenario?

  1. A

    Enables collaboration by allowing multiple developers to work on the same project simultaneously

  2. B

    Provides a mechanism to roll back to previous versions of the codebase if issues arise

  3. C

    Automatically resolves all code conflicts without developer intervention

  4. D

    Maintains a detailed history of changes for auditing and debugging purposes

  5. E

    Ensures that code is automatically tested and deployed without requiring additional tools or workflows

Show answer and explanation

Correct answers: A, B, D

Explanation

Version control systems, like Git, are essential tools for modern software development because they enable collaboration, provide a mechanism to track and manage changes, allow rollbacks to previous versions, and maintain a detailed history of the codebase. However, tasks like automated testing and deployment require integration with other tools, and developers must still address merge conflicts manually when they arise.

  • A. Correct.

    Correct. Version control systems facilitate collaboration by allowing multiple developers to work on the same project, track changes, and merge contributions.

  • B. Correct.

    Correct. Version control systems such as Git provide the ability to roll back to previous versions of the codebase, which is essential for debugging and reverting problematic changes.

  • C. Incorrect.

    Incorrect. While version control systems can help manage conflicts, they do not automatically resolve all conflicts. Developers must manually address conflicts in many cases.

  • D. Correct.

    Correct. A key feature of version control systems is the ability to maintain a history of changes, which is useful for auditing, debugging, and understanding the evolution of the codebase.

  • E. Incorrect.

    Incorrect. Version control systems do not inherently handle automated testing or deployments. These require integration with CI/CD tools or workflows.
