Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The CMMC Scoping Guidance specifies that Contractor Risk Managed Assets must:

Be documented in the asset inventory,

Be governed by the organization’s own risk-based policies and procedures,

Be included in the system boundary/network diagram.

Extract:

“Contractor Risk Managed Assets are those managed according to the OSC’s risk-based policies and procedures. They must be documented in the asset inventory and represented in the system boundary.”

Thus, option C is the best answer.

The control SC.L2-3.13.5: Boundary Protection requires that organizations monitor and control communications at the external boundary and at key internal boundaries. The CMMC Assessment Guide states that assessors should examine boundary protection procedures to verify logging, monitoring, and alerting are defined and implemented. Physical access logs, account management documents, and configuration management policies do not provide details of how network boundaries are monitored and protected.

Exact extracts:

“Assessment Objectives … Determine if: • external boundary and key internal boundaries are defined; • communications are monitored and controlled at boundaries; • traffic is checked for unauthorized transfer of information; and • boundary protection devices are configured and managed.”

“Potential Assessment Methods: Examine … boundary protection policy; boundary protection procedures; system security plan; configuration settings for boundary protection devices; logs of boundary protection devices.”

Why the other options are incorrect:

A (Physical access logs): Relates to facility entry, not network boundary protection.

C (Account management document): Addresses user account lifecycle, not firewall and traffic control.

D (Configuration management policy): Governs system changes, not firewall logging/alerting controls.

===========

Applicable Requirement (CMMC Scoping Guidance – Specialized Assets): Specialized Assets (e.g., OT, IoT, GFE, test equipment) are not exempt from CMMC practices. OSCs must provide:

Documented identification in SSP/inventory,

Justification of specialized handling,

Evidence that risk-based security measures are implemented.

Why D is Correct: Assessors must see evidence that isolation is actually implemented (not just planned), plus supporting artifacts showing how remaining applicable practices are addressed (monitoring, inventory, access, etc.). Planned measures alone are insufficient.

Why Other Options Are Insufficient:

A: Installation/config builds do not show operational isolation.

B: Scoping statements alone do not demonstrate implementation.

C: SSP language is descriptive but must be supported by implementation evidence.
