Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The Physical Protection (PE) practices require both direct assessor observation of security controls and verification of how the OSC manages access to its cages/cabinets.

Extract:

“Assessors should observe and verify the effectiveness of physical access controls and confirm the OSC’s processes for maintaining control over restricted areas and assets.”

Thus, the best option is to physically visit the facility and review OSC’s key access management process.

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 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).
