Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

Applicable Requirement: PE.L2-3.10.3 — “Control physical access to organizational systems, equipment, and the respective operating environments.”

Why A is Correct: Security guards are a recognized preventive and detective physical control to limit access to only authorized individuals. Guards can verify credentials, monitor behavior, and provide real-time deterrence.

Why Other Options Are Insufficient:

B (Cameras): Provide monitoring and evidence, but not direct access control.

C (Firewalls): A network control, not a physical access measure.

D (Partition walls): Barriers may help physically separate areas but do not control who enters.

===========

The Physical Protection (PE) requirements require that systems containing FCI or CUI be placed in controlled-access facilities with safeguards against unauthorized physical access.

Extract from PE.L2-3.10.1:

“Limit physical access to organizational information systems, equipment, and the respective operating environments to authorized individuals.”

Thus, ensuring that the VMs run on hardware located in a controlled-access facility is the correct method to meet physical security requirements.

MA.L2-3.7.1 (Perform Maintenance) requires that maintenance activities and risks associated with outdated or unsupported systems be managed. Unsupported systems create a security risk if not mitigated, particularly when they process CUI.

Extract:

“Maintenance must be performed and documented to ensure continued secure operation. When systems cannot be updated or patched due to technical limitations, the OSC must implement and document risk mitigation strategies.”

Because the OSC has not demonstrated risk management for the outdated OT system, the practice is NOT MET.
