According to the CMMC Assessment Process (CAP), specifically during the Phase 3: Conduct Assessment (Evidence Collection and Verification), the Assessment Team must evaluate all collected artifacts, interview notes, and test results against two primary dimensions: Adequacy and Sufficiency.
Adequacy (The "Right" Evidence): This criterion focuses on the quality, relevance, and validity of the evidence. It addresses whether the evidence actually maps to the specific CMMC practice being assessed and whether it is authoritative (e.g., signed, current, and from a trusted source). If an assessor asks, "Is this therightpiece of information to prove this practice is met?" they are testing for Adequacy.
Sufficiency (The "Enough" Evidence): This criterion focuses on the quantity and scope of the evidence. It addresses whether the Assessment Team has collected enough data points (across the required number of assets and using the required methods of Examine, Interview, and Test) to reach a confident conclusion. If an assessor asks, "Do I haveenoughexamples of this practice in action across the entire enclave?" they are testing for Sufficiency.
Why other options are incorrect:
B and D (Objectivity/Subjectivity): While assessors must remain objective, these are not the formal "criteria" used to categorize the evidence collection quality within the CAP framework.
C (Sufficiency): As noted above, Sufficiency is about theamountof evidence, not whether it is thecorrect type(the "right" evidence).
