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.

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.

===========

The negative finding is that the OSC permits an uncertified external security provider to access the OSC’s internal network. This introduces unmanaged risk to the CUI environment. CMMC requires the OSC to control and monitor external service provider access. The storage of recordings externally is not inherently noncompliant if properly controlled, and video monitoring is a valid method of meeting PE.L2-3.10.2. The key failure is giving unmanaged third-party access.

Exact extracts:

“Monitor physical facility to detect and respond to physical security incidents.” (PE.L2-3.10.2)

“Assessment Objectives … Determine if: monitoring is performed; unauthorized physical access is detected and responded to.”

“External service providers that connect into the OSC network are considered in-scope and must meet CMMC requirements or have equivalent authorization (e.g., FedRAMP).”

Why other options are incorrect:

A: Requirement does not mandate monitoring of both public and private areas.

C: Video surveillance is an acceptable facility monitoring method when properly implemented.

D: External storage can be acceptable if contractual safeguards and compliance are in place.
