Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The CMMC Assessment Process (CAP) requires that results be reported at the OSC level. While findings may be gathered from enclaves or units, the final reporting must be aggregated and scored across the entire OSC assessment boundary.

Extract:

“Final recommended assessment results must be consolidated and reported at the OSC level, regardless of assessment locations or enclaves.”

Thus, the Lead Assessor must ensure aggregation to the OSC level.

CMMC requires that remote maintenance sessions be terminated after use or after a defined period of inactivity. This ensures third-party maintenance access does not remain open and uncontrolled, preventing unauthorized persistence.

Exact Extracts:

MA.L2-3.7.5: “Require multifactor authentication and terminate remote maintenance sessions after each session or after a defined period of inactivity.”

Assessment Guide clarifies: “Assessors should confirm remote maintenance sessions are automatically terminated using technical means.”

NIST SP 800-171A Objective: “Test maintenance session termination after a set time of inactivity or completion of task.”

Why other options are not correct:

A: Limiting maintenance to third parties only is not a requirement. Internal staff may also perform maintenance.

B: Identification and monitoring are important, but the specific control required here is termination of remote sessions.

C: Limiting the number of personnel is not mandated by CMMC.

The OSC is responsible for identifying and declaring where CUI is processed, stored, or transmitted. A Certified CMMC Assessor (CCA) may verify boundaries, examine evidence, and confirm monitoring or control practices, but cannot independently determine if a physically separated asset contains CUI. That determination is the responsibility of the OSC, not the assessor.

Exact extracts:

“The OSC is responsible for identifying CUI assets.”

“Assessors verify and validate the OSC’s identification, but do not independently declare or determine the presence of CUI.”

“Assessors are permitted to examine boundary protections, monitoring mechanisms, and internal boundary controls.”

Why the other options are allowed:

A: Assessors are required to verify internal system boundaries.

C: Assessors must confirm that external system boundaries are clearly defined.

D: Assessors must examine evidence of communication monitoring.
