What components should maintenance documentation include according to CMMC Level 2 practices?

The correct choice emphasizes the comprehensive nature of maintenance documentation required for CMMC Level 2 practices. This level mandates that organizations must not only schedule and approve maintenance activities but also ensure that the entire maintenance lifecycle is meticulously documented. This includes performing the maintenance, documenting the process, reviewing the work done, approving the results of the maintenance, and consistently monitoring the effectiveness and need for future maintenance.

This holistic approach is key for organizations to ensure accountability, continuity, and traceability of their maintenance activities. Maintaining detailed records helps verify that all tasks are performed correctly and supports the identification of any recurring issues or areas needing improvement. By having a complete documentation process, organizations enhance their operational integrity and security posture, which is essential for compliance with the CMMC standards.

In contrast, other options fall short of this comprehensive requirement. They either focus on limited aspects of maintenance documentation or do not encompass the entire process needed to maintain security and operational effectiveness.
