Code review is best described as which of the following?

• A. A peer review process in which programmers check over one another's work to ensure its quality
• B. A method of version control
• C. A security audit by external testers
• D. A formal test of system performance under load

Answer: (A)

Code review is a peer-driven process where programmers examine each other’s code to improve quality. In practice, a reviewer checks for correctness, readability, adherence to project standards, potential bugs, and maintainability issues. This collaborative check helps catch problems early, shares knowledge across the team, and ensures changes fit well with the codebase before they are merged. It’s tied to the development workflow, often happening through pull requests or merge requests. This isn’t about version control itself, which is the system for tracking changes; it isn’t an external security audit focused on vulnerabilities, and it isn’t a performance test that measures how the system behaves under load. The description that best captures what code review is describes a peer review process where programmers check one another’s work to ensure its quality.
