New Release CMMC-CCA CMMC Questions

When CUI and FCI reside on the same network, the entire environment is considered a CUI environment. The presence of CUI drives the assessment requirement to CMMC Level 2, regardless of whether FCI also exists. Assets cannot be assessed separately under Level 1 vs. Level 2 within the same network boundary.

Exact extracts:

“If CUI is processed, stored, or transmitted within an environment, the environment is in scope for CMMC Level 2.”

“The presence of CUI dictates the assessment level, regardless of whether FCI is also present.”

“Segmentation may reduce scope, but if assets remain within the same environment, all assets fall under Level 2.”

Why other options are incorrect:

B: Level 1 cannot be applied to Server A while Server B undergoes Level 2 in the same network.

C: Presence of CUI means Level 2 is required, not Level 1.

D: Segmentation can reduce scope but is not required before assessment; it is an OSC design choice.

CMMC requires physical access to systems containing or transmitting CUI to be limited to authorized individuals and for access records to be maintained. Badge readers with unique identification provide individual accountability, access control enforcement, and auditable access logs, which are stronger than labels, cameras, or keypads.

Exact Extracts:

PE.L2-3.10.1: “Limit physical access to organizational systems, equipment, and the respective operating environments to authorized individuals.”

PE.L2-3.10.5: “Maintain audit logs of physical access.”

CMMC Assessment Guide: “Badge systems with access control lists and logs are considered a best method for meeting physical access requirements.”

Why the other options are not correct:

A: Labels and lists do not prevent unauthorized access.

C: Cameras monitor but do not restrict access; they are detective, not preventive.

D: Keypads do not provide individual accountability (codes can be shared).

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.

CMMC Level 2 requires that network access to CUI systems be restricted to authorized users and devices. A guest network without password protection that connects directly into the LAN violates AC.L2-3.1.3 (Access Enforcement) and SC.L2-3.13.16 (Cryptographic protection) because unauthorized users may access OSC systems and CUI indirectly.

Exact Extracts:

AC.L2-3.1.3: “Control the flow of CUI by enforcing access restrictions.”

SC.L2-3.13.16: “Employ cryptographic mechanisms to protect confidentiality of CUI during transmission.”

Assessment Guide: “Guest wireless networks must be segmented and controlled to prevent unauthorized access to internal networks containing CUI.”

Why other options are not correct:

A: Additional assessment is irrelevant — issue is failure to meet requirements.

C/D: False — requirements clearly exist, and the OSC’s current setup fails them.
