Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

Both the CSP’s cloud environment and the OSC’s on-premises network/workstations are in-scope because CUI is stored in the cloud but also accessed and transmitted by OSC assets. The cloud vendor’s internal employee network is not in-scope because only the customer-facing FedRAMP environment is within the assessment boundary.

Exact extracts:

“CUI Assets include any OSC asset that stores, processes, or transmits CUI.”

“External service providers are in-scope if their services process, store, or transmit CUI on behalf of the OSC.”

“The OSC’s endpoints and local infrastructure that access CUI are also in-scope.”

Why the other options are incorrect:

A: Cloud environment only is incomplete; OSC workstations also access and transmit CUI.

B: OSC network only ignores the fact that CUI is stored in the cloud.

D: The cloud vendor’s internal employee network is not in-scope.

Applicable Requirement: CM.L2-3.4.3 — “Track, review, approve/disapprove, and audit changes to organizational systems.”

Why CCB Minutes Are Correct (supports B):

Change Control Board (CCB) documentation includes impact analyses, approvals, disapprovals, and justification for system changes.

The CMMC Assessment Guide explicitly identifies CCB minutes and supporting records as primary evidence of compliance with change management practices.

Why Other Options Are Insufficient:

A (Vendor description): Provides information on the update, but does not show organizational review or approval.

C (Audit logs): Show when a change occurred, but not whether it was analyzed and approved beforehand.

D (Incident logs): Reflects results after implementation, but not the review/approval process.

Assessment Guidance Extract (NIST SP 800-171A, CM.L2-3.4.3):

Objectives include verifying that system changes are:

Documented,

Reviewed,

Approved/disapproved, and

Audited.

Evidence such as CCB minutes and approval records directly satisfies these objectives.

Applicable Requirement: PE.L2-3.10.1 — “Limit physical access to organizational information systems, equipment, and the respective operating environments to authorized individuals.”

Why D is Correct: Documented procedures describing physical access restrictions (badge policies, visitor management, locked server rooms, guard post orders) serve as primary evidence that access is managed and enforced. Assessors can then corroborate via interviews and observation.

Why Other Options Are Insufficient:

A (VPN configuration): Relates to remote logical access, not physical security.

B (Switch configs): Technical network controls, not physical access.

C (Architecture drawings): Show logical/system design, not physical entry restrictions.
