What does rollback mean?

• A. Update to the latest version
• B. Create a new feature branch
• C. Revert to the previous version if issues occur
• D. Deploy multiple servers

Answer: (C)

Rollback means returning a system to a previous, stable state after problems are found in a recent release. It’s the process of undoing recent changes so the software behaves like the earlier version, helping restore reliability quickly while a fix is prepared. This happens when issues like bugs or performance problems appear after deployment and can’t be quickly resolved in place. So, reverting to the previous version if issues occur best captures the idea. It’s not about moving forward to the latest version, not about starting a new feature branch during development, and not about deploying to multiple servers for scalability; those relate to other aspects of development and deployment rather than undoing recent changes.
