Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

Applicable Requirement: SC.L2-3.13.16 — “Protect the confidentiality of CUI at rest.”

Why D is Correct: Cryptographic mechanisms (e.g., full-disk encryption, database encryption, file encryption) provide the strongest protection for information at rest by preventing unauthorized disclosure if systems or media are accessed.

Why Other Options Are Insufficient:

A (Patching): Protects against vulnerabilities, but not specific to data-at-rest confidentiality.

B (File share): Provides a storage method, not protection.

C (Secure offline storage): Helps physically, but not sufficient for digital confidentiality without encryption.

CMMC Assessment Guide – Level 2, Data at Rest Protection

===========

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.

The CMMC Assessment Process (CAP) requires that results be reported at the OSC level. While findings may be gathered from enclaves or units, the final reporting must be aggregated and scored across the entire OSC assessment boundary.

Extract:

“Final recommended assessment results must be consolidated and reported at the OSC level, regardless of assessment locations or enclaves.”

Thus, the Lead Assessor must ensure aggregation to the OSC level.
