CMMC-CCA Exam Dumps : Certified CMMC Assessor (CCA) Exam

CMMC requires that remote maintenance sessions be terminated after use or after a defined period of inactivity. This ensures third-party maintenance access does not remain open and uncontrolled, preventing unauthorized persistence.

Exact Extracts:

MA.L2-3.7.5: “Require multifactor authentication and terminate remote maintenance sessions after each session or after a defined period of inactivity.”

Assessment Guide clarifies: “Assessors should confirm remote maintenance sessions are automatically terminated using technical means.”

NIST SP 800-171A Objective: “Test maintenance session termination after a set time of inactivity or completion of task.”

Why other options are not correct:

A: Limiting maintenance to third parties only is not a requirement. Internal staff may also perform maintenance.

B: Identification and monitoring are important, but the specific control required here is termination of remote sessions.

C: Limiting the number of personnel is not mandated by CMMC.

The Physical Protection (PE) practices require that unmanned access points to areas containing CUI be restricted with technical controls that only allow entry to authorized personnel. While cameras, signage, and turnstiles support security, they do not actually prevent access.

Extract from PE.L2-3.10.1:

“Limit physical access to organizational information systems, equipment, and the respective operating environments to authorized individuals.”

The strongest measure listed is one-way gates requiring credentials or intercom authorization, which directly enforces access control.

Certification can only be granted to the legal entities that own the CAGE codes under assessment. If multiple CAGE codes are in play (HQ, host, and supporting units), and they are all included in scope, then all entities with corresponding CAGE codes that were assessed can be certified.

Exact Extracts:

CMMC Assessment Guide: “The CMMC certificate is issued to the legal entity (as identified by the CAGE code(s)) that was assessed.”

“When multiple CAGE codes are presented, all in-scope entities must provide documentation and may be certified if assessed.”

“Certification applies to the OSC legal entity (or entities) within scope, including HQ, host, and supporting units, as applicable.”

Why other options are not correct:

A/B/C: Limit scope to only HQ or subsets, but the requirement is that all entities with provided and in-scope CAGE codes are eligible.
