Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

In CMMC scoping, only assets that process, store, or transmit CUI (CUI Assets) or that can access them (Security Protection, Contractor Risk Managed, Specialized Assets) are in-scope. Since the SCADA system is firewalled off and does not handle CUI, it does not fall under CUI Asset classification and is considered Out-of-Scope.

Exact extracts:

“CUI Assets are those that process, store, or transmit CUI.”

“Assets that do not process, store, or transmit CUI and have no connectivity to CUI Assets are considered Out-of-Scope.”

“Specialized Assets… are only in-scope if they process, store, or transmit CUI.”

Why the other options are incorrect:

A: Inclusion requires processing/storing/transmitting CUI.

C: OSC cannot arbitrarily bring unrelated systems into scope; CUI relevance governs scope.

D: Not all Specialized Assets are in-scope; only those with CUI interaction are.

Under AT.L2-3.2.3 (Security Awareness Training) and AT.L2-3.2.2 (Insider Threat Training), insider threat awareness training must equip personnel to recognize and report indicators of insider threat activity. Training must focus on organizational processes for reporting suspicious behavior, not just awareness of famous cases or punitive systems. The ability to act and report appropriately is the most critical element.

Exact extracts:

“Training includes recognition of potential indicators of insider threat activity and the organizational processes for reporting suspicious activity.”

“Assessment Objectives … Determine if: insider threat training includes reporting mechanisms.”

“Case studies may be used for context, but training must include clear reporting procedures.”

Expanded explanation:

Insider threat programs under DoD guidance (e.g., NISPOM, CMMC) emphasize:

Awareness of behaviors that may indicate insider threat activity.

Reporting mechanisms — employees must know exactly how to act if they identify an issue.

Procedures for escalation and protection of CUI.

Without reporting procedures, insider threat training is incomplete.

Why other options are incorrect:

A: Bounty systems are not sanctioned practices and could create a hostile work environment.

B: Risk-ranking individuals could be discriminatory and is not a CMMC requirement.

C: Case studies may supplement training but are not sufficient by themselves.

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.
