Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

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.

The Physical Protection (PE) Domain requires implementation of physical access controls to prevent unauthorized access to CUI systems. Simply trusting employees or sending communications is not sufficient. However, if the server is located inside a secondary restricted room that only the IT team can access, then adequate physical protection controls are still in place.

Extract from PE.L2-3.10.x (Physical Protection Practices):

“Organizations must limit physical access to systems, equipment, and environments that process, store, or transmit CUI to authorized individuals only.”

Thus, placing the server within an additional restricted access-controlled room ensures compliance, even if the outer door is propped open for cooling.

CMMC Level 2 requires that network access to CUI systems be restricted to authorized users and devices. A guest network without password protection that connects directly into the LAN violates AC.L2-3.1.3 (Access Enforcement) and SC.L2-3.13.16 (Cryptographic protection) because unauthorized users may access OSC systems and CUI indirectly.

Exact Extracts:

AC.L2-3.1.3: “Control the flow of CUI by enforcing access restrictions.”

SC.L2-3.13.16: “Employ cryptographic mechanisms to protect confidentiality of CUI during transmission.”

Assessment Guide: “Guest wireless networks must be segmented and controlled to prevent unauthorized access to internal networks containing CUI.”

Why other options are not correct:

A: Additional assessment is irrelevant — issue is failure to meet requirements.

C/D: False — requirements clearly exist, and the OSC’s current setup fails them.
