Pass the Cyber AB CMMC CMMC-CCA Questions and answers with CertsForce

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.

If the OSC cannot remediate deficiencies during the POA&M Close-Out process, the Lead Assessor must issue a recommendation of NOT MET, and the OSC will not be certified. CMMC requires all Level 2 practices to be MET (with limited exceptions under defined POA&M close-out rules).

Exact Extracts:

CMMC Assessment Guide: “If practices cannot be met within the POA&M Close-Out process, the Lead Assessor must not recommend certification.”

DoD policy: “CMMC Level 2 requires that all 110 practices be met. A failed POA&M Close-Out results in a final determination of NOT MET.”

“There is no provisional certification status in CMMC.”

Why the other options are not correct:

A: Assessments are not paused indefinitely; unresolved deficiencies result in NOT MET.

B: Justification alone does not satisfy requirements.

C: Provisional status does not exist in CMMC.

Per the CMMC Scoping Guidance, CUI Assets are those that process, store, or transmit CUI. Since System CUI is the system handling CUI data, it must be categorized as CUI Assets.

Extract:

“CUI Assets are any assets that process, store, or transmit CUI. These assets are in-scope for assessment and must meet CMMC practice requirements.”

Thus, the best classification for System CUI is CUI Assets.

The CMMC Scoping Guidance defines Specialized Assets (e.g., OT, IoT, test equipment, manufacturing machines) that may process CUI but do not always meet traditional IT security requirements. These assets are still within scope and must be documented and assessed as Specialized Assets.

Extract:

“Specialized Assets are defined as operational technology, IoT, test equipment, and similar devices that may process CUI but cannot be secured in the same manner as standard assets. They remain in-scope for the assessment.”

Thus, waterjet machines are Specialized Assets in scope.

The CMMC Assessment Process (CAP) requires that when sensitive or proprietary materials are exchanged during an assessment, the OSC and the C3PAO should establish confidentiality protections through a Non-Disclosure Agreement (NDA).

Extract:

“OSC and C3PAOs are expected to execute a Non-Disclosure Agreement (NDA) to protect sensitive information such as proprietary, attorney-client privileged, or pre-patent materials shared during the assessment process.”

Thus, the NDA is the correct document.
