Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The Physical Protection (PE) Domain requires implementation of physical access controls to prevent unauthorized access to CUI systems. Simply trusting employees or sending communications is not sufficient. However, if the server is located inside a secondary restricted room that only the IT team can access, then adequate physical protection controls are still in place.

Extract from PE.L2-3.10.x (Physical Protection Practices):

“Organizations must limit physical access to systems, equipment, and environments that process, store, or transmit CUI to authorized individuals only.”

Thus, placing the server within an additional restricted access-controlled room ensures compliance, even if the outer door is propped open for cooling.

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).

The Shared Responsibility Matrix (Customer Responsibility Matrix) is the authoritative document that specifies which security responsibilities are owned by the OSC versus the Cloud Service Provider (CSP). This enables assessors to determine which CMMC practices apply to the OSC and which are inherited from the provider.

Exact extracts:

“External Service Providers (ESPs), including CSPs, must provide a Shared Responsibility Matrix that delineates customer versus provider responsibilities.”

“Assessors should request and review this matrix to determine practice applicability.”

Why other options are incorrect:

A: Zero Trust Architecture is a design framework, not a responsibility breakdown.

C: White papers are marketing/technical resources, not binding assignments of responsibility.

D: IAM Plans address access management, not overall shared responsibilities.
