An Assessment Team is reviewing a practice that is documented and being checked monthly.

 Understanding CMMC Assessment Requirements

CMMC assessments usethree assessment methodsto verify compliance with security practices:

Examine– Reviewing documentation, policies, logs, or records.

Interview– Speaking with personnel to confirm understanding and execution.

Test– Verifying through technical or operational means that the practice is being performed.

 Assessment Findings in the Given Scenario

Practice is documented as occurring monthly, but logs show quarterly execution.

Interviews indicate monthly execution, but documentation does not support this claim.

 Why the Organization Fails the Practice

Answer A (Incorrect): The work is being performed, but documentation is lacking, so the failure is not purely due to missing execution.

Answer B (Incorrect): The documented frequency does not match the evidence in logs, so the practice is not being done asfully documented.

Answer C (Correct):CMMC requires all three assessment methods (Examine, Interview, Test) to align. Since logs contradict the stated frequency, the practicefailscompliance.

Answer D (Incorrect): Interview responses alone are not enough. The CMMCCAP GuideandNIST SP 800-171Arequire corroboration with logs (Examine) and technical verification (Test).

 Conclusion

The correct answer isC: To pass a practice, the organization mustprovide evidence across all three assessment methods.
