CMMC-CCA Exam Dumps : Certified CMMC Assessor (CCA) Exam

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

Why D is Correct: Documented procedures describing physical access restrictions (badge policies, visitor management, locked server rooms, guard post orders) serve as primary evidence that access is managed and enforced. Assessors can then corroborate via interviews and observation.

Why Other Options Are Insufficient:

A (VPN configuration): Relates to remote logical access, not physical security.

B (Switch configs): Technical network controls, not physical access.

C (Architecture drawings): Show logical/system design, not physical entry restrictions.

CMMC Assessment Guide – Level 2 — Physical Protection Evidence Guidance

Both the CSP’s cloud environment and the OSC’s on-premises network/workstations are in-scope because CUI is stored in the cloud but also accessed and transmitted by OSC assets. The cloud vendor’s internal employee network is not in-scope because only the customer-facing FedRAMP environment is within the assessment boundary.

Exact extracts:

“CUI Assets include any OSC asset that stores, processes, or transmits CUI.”

“External service providers are in-scope if their services process, store, or transmit CUI on behalf of the OSC.”

“The OSC’s endpoints and local infrastructure that access CUI are also in-scope.”

Why the other options are incorrect:

A: Cloud environment only is incomplete; OSC workstations also access and transmit CUI.

B: OSC network only ignores the fact that CUI is stored in the cloud.

D: The cloud vendor’s internal employee network is not in-scope.

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.
