Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The Scoping Guidance for Specialized Assets allows exclusion of assets when they are physically and logically isolated from the CMMC assessment boundary and do not process, store, or transmit CUI.

Extract from CMMC Scoping Guidance:

“Specialized Assets may be designated as out-of-scope if they are physically or logically separated from CUI assets, or if they are inherently unable to process, store, or transmit CUI.”

The camera system in this case does not interact with CUI and is fully isolated, making exclusion appropriate.

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 Shared Responsibility Matrix (Customer Responsibility Matrix) is the authoritative document that specifies which security responsibilities are owned by the OSC versus the Cloud Service Provider (CSP). This enables assessors to determine which CMMC practices apply to the OSC and which are inherited from the provider.

Exact extracts:

“External Service Providers (ESPs), including CSPs, must provide a Shared Responsibility Matrix that delineates customer versus provider responsibilities.”

“Assessors should request and review this matrix to determine practice applicability.”

Why other options are incorrect:

A: Zero Trust Architecture is a design framework, not a responsibility breakdown.

C: White papers are marketing/technical resources, not binding assignments of responsibility.

D: IAM Plans address access management, not overall shared responsibilities.
