200-901 Question 18
Select 3As 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?
- A
Enables collaboration by allowing multiple developers to work on the same project simultaneously
- B
Provides a mechanism to roll back to previous versions of the codebase if issues arise
- C
Automatically resolves all code conflicts without developer intervention
- D
Maintains a detailed history of changes for auditing and debugging purposes
- 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.
