Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The requirement for CA.L2-3.12.3 – Security Control Monitoring mandates monitoring to be performed on an ongoing basis to ensure the continued effectiveness of the controls. This is not satisfied by a yearly review alone.

CA.L2-3.12.3 Security Control Monitoring – Monitor security controls on an ongoing basis to ensure the continued effectiveness of the controls.

The OSC’s statement in their SSP that monitoring occurs on a one-year periodic basis fails to meet this requirement, because the term "ongoing basis" implies continual or recurring monitoring activities that occur throughout the system’s lifecycle—not a single annual review.

Therefore, the assessor must determine that the OSC’s implementation is not acceptable.

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.

CMMC Level 2 requires that network access to CUI systems be restricted to authorized users and devices. A guest network without password protection that connects directly into the LAN violates AC.L2-3.1.3 (Access Enforcement) and SC.L2-3.13.16 (Cryptographic protection) because unauthorized users may access OSC systems and CUI indirectly.

Exact Extracts:

AC.L2-3.1.3: “Control the flow of CUI by enforcing access restrictions.”

SC.L2-3.13.16: “Employ cryptographic mechanisms to protect confidentiality of CUI during transmission.”

Assessment Guide: “Guest wireless networks must be segmented and controlled to prevent unauthorized access to internal networks containing CUI.”

Why other options are not correct:

A: Additional assessment is irrelevant — issue is failure to meet requirements.

C/D: False — requirements clearly exist, and the OSC’s current setup fails them.
