What does a practice marked as "MET" indicate?

The designation of "MET" signifies that a practice has been assessed and found to conform to all specified objectives, which is crucial within the framework of the Cybersecurity Maturity Model Certification (CMMC). This means that not only has the practice been thoroughly evaluated, but there is also supporting evidence to demonstrate that it meets the necessary criteria established by the CMMC requirements.

When a practice is marked as "MET," it indicates a successful alignment with the expectations set forth in the CMMC standards, showing that the organization has implemented the necessary controls and processes effectively. The supporting evidence could include documentation, records, or other proofs that validate the practice's effectiveness and adherence to the goals of maintaining cybersecurity maturity.

The other options do not accurately reflect the meaning of "MET." For example, non-conformance with objectives would imply that expectations have not been met, while completion of all assessment activities suggests that assessments are simply finished without confirming the level of conformity. An exemption from assessment requirements indicates bypassing certain criteria, which would not imply adherence or successful implementation in any way.
