What term refers to changes to a system resulting from error corrections, performance improvements, changes in the business environment, and enhancements?

• A. Upgrade
• B. Deployment
• C. Maintenance
• D. Patch

Answer: (C)

This is about maintenance. Maintenance covers the ongoing changes a system undergoes to stay reliable and useful: fixing defects (error corrections), improving performance, adapting to shifts in the business environment (like new policies, processes, or hardware), and adding enhancements. It’s the ongoing work that keeps a system functioning well after its initial release. A patch is a narrower thing—a specific fix for a defect or vulnerability. An upgrade is a major version change that adds significant new features. Deployment is the process of delivering and installing software. Since the described changes span bug fixes, performance tweaks, environmental adaptations, and new improvements, maintenance is the best fit.
