Which type of maintenance modification is used to improve performance?

• A. Perfective maintenance
• B. Adaptive maintenance
• C. Preventive maintenance
• D. Corrective maintenance

Answer: (A)

The question is about different kinds of changes made to software after it’s in use, specifically which type aims to make things run better. Perfective maintenance is the one that focuses on improving performance, efficiency, or overall functionality. It’s about enhancements that make the system work better, not about fixing faults, adapting to a new environment, or preventing future problems. Adaptive maintenance changes software so it works in a changed environment or with new systems. Preventive maintenance is about restructuring or tidying code to reduce the chance of future problems. Corrective maintenance fixes defects that are found.
