Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The OSC is responsible for identifying and declaring where CUI is processed, stored, or transmitted. A Certified CMMC Assessor (CCA) may verify boundaries, examine evidence, and confirm monitoring or control practices, but cannot independently determine if a physically separated asset contains CUI. That determination is the responsibility of the OSC, not the assessor.

Exact extracts:

“The OSC is responsible for identifying CUI assets.”

“Assessors verify and validate the OSC’s identification, but do not independently declare or determine the presence of CUI.”

“Assessors are permitted to examine boundary protections, monitoring mechanisms, and internal boundary controls.”

Why the other options are allowed:

A: Assessors are required to verify internal system boundaries.

C: Assessors must confirm that external system boundaries are clearly defined.

D: Assessors must examine evidence of communication monitoring.

CMMC Code of Professional Conduct (OSC retains CUI ownership; assessors validate but cannot declare CUI).

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.

To validate that remote access is routed through managed access control points, the assessor requires technical evidence, not just policy. The network diagram shows the design and routing of remote access through controlled points (e.g., VPN gateways), and VPN logs provide operational evidence that remote sessions are enforced through those points.

Exact Extracts:

AC.L2-3.1.14: “Route remote access through managed access control points.”

Assessment Objective (AC.L2-3.1.14[a]): “Remote access is routed through managed access control points.”

Assessment Method (Examine/Interview/Test): Requires network diagrams and remote access logs as evidence.

CMMC Assessment Guide specifies: “Network diagrams and supporting logs are required to demonstrate implementation of remote access routing.”

Why the other options are not correct:

B (policy/procedures): Policies describe intent, not proof of implementation.

C (SSP/vendor mgmt): SSPs provide system description but not direct evidence of enforcement.

D (cloud logs/hardware inventory): These do not specifically demonstrate remote access routing through managed points.
