Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

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.

===========

If the OSC cannot remediate deficiencies during the POA&M Close-Out process, the Lead Assessor must issue a recommendation of NOT MET, and the OSC will not be certified. CMMC requires all Level 2 practices to be MET (with limited exceptions under defined POA&M close-out rules).

Exact Extracts:

CMMC Assessment Guide: “If practices cannot be met within the POA&M Close-Out process, the Lead Assessor must not recommend certification.”

DoD policy: “CMMC Level 2 requires that all 110 practices be met. A failed POA&M Close-Out results in a final determination of NOT MET.”

“There is no provisional certification status in CMMC.”

Why the other options are not correct:

A: Assessments are not paused indefinitely; unresolved deficiencies result in NOT MET.

B: Justification alone does not satisfy requirements.

C: Provisional status does not exist in CMMC.

Malicious code protection is typically implemented and managed by system or network administrators, who configure, deploy, and monitor anti-malware solutions. Interviews with these administrators provide direct evidence of control implementation.

Exact Extracts:

SI.L2-3.14.2: “Provide protection from malicious code at appropriate locations within organizational information systems.”

CMMC Assessment Guide: “Interviews should be conducted with administrators responsible for deployment and monitoring of malicious code protection.”

NIST SP 800-171A (SI.L2-3.14.2): “Interview system or network administrators to determine how malicious code protection is implemented.”

Why other options are not correct:

A (developers): Developers do not typically manage system-wide malicious code protections.

C (audit personnel): They review logs, not deploy/manage protections.

D (security advisory staff): They track alerts but don’t operate malicious code defenses.
