Which of the following is NOT a maintenance process that assists in minimizing system disruptions during updates?

• A. Implementing rollbacks
• B. Capacity planning
• C. Establishing release schedules
• D. Monitoring user activity

Answer: (D)

The correct choice identifies a process that does not directly contribute to minimizing system disruptions during updates. Monitoring user activity primarily focuses on understanding how users interact with the system and identifying potential usability issues or performance bottlenecks. While it is valuable for ongoing operational effectiveness, it does not specifically address the mechanics of managing updates or changes to the system.

In contrast, implementing rollbacks is a critical maintenance process that allows a system to revert to a previous stable version if an update introduces issues. Capacity planning involves ensuring that the system has the necessary resources to handle various workloads, which can also reduce disruptions. Establishing release schedules ensures that updates are deployed in a systematic manner, giving teams time to prepare and minimizing unexpected downtime. Each of these processes is more directly tied to the goal of managing updates with minimal disruption to users and services.
