Cyber AB CMMC-CCA Exam With Confidence Using Practice Dumps

The OSC (Organization Seeking Certification) is always responsible for meeting CMMC requirements, regardless of what responsibilities are shared or outsourced to an ESP. ESPs can provide inherited practices (e.g., FedRAMP Moderate for cloud CUI), but the OSC remains accountable for compliance under government mandates.

Exact Extracts:

CMMC Assessment Guide: “The OSC is the entity being assessed. While an ESP may provide inherited practices, the OSC retains ultimate responsibility for compliance.”

Scoping Guide: “External Service Providers may meet requirements on behalf of the OSC; however, it is the OSC that is assessed and must demonstrate sufficiency of evidence.”

Why other options are not correct:

A: Incorrect — ESPs that process CUI must meet FedRAMP Moderate equivalency, even if not directly assessed for CMMC.

B: While true, factoring documentation does not override that OSC remains accountable.

C: ESPs are not assessed at the same time as the OSC; only the OSC receives certification.

The Physical Protection (PE) practices require that visitors to facilities where CUI is processed must be escorted at all times by an authorized individual. Familiarity or long-term knowledge of the visitor does not remove the requirement.

Extract from PE.L2-3.10.3:

“Escort visitors and monitor visitor activity to ensure they do not access areas or information for which they are not authorized.”

Thus, the correct action is for the contact person (the engineer’s point of contact) to escort the engineer during the entire maintenance activity.

CMMC scoping focuses on assets that process, store, transmit, or protect CUI. A smoke detector connected to the OSC network is an IoT device with no impact on CUI, so it is considered Out-of-Scope. The other items (data centers used by the OSC, MSP SIEM tools, and MSP offices handling OSC management) all directly affect the OSC’s CUI environment and therefore fall within scope.

Exact extracts:

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

“Security Protection Assets are those that provide security functions for CUI Assets.”

“External Service Providers (e.g., MSPs, data centers, SIEMs) that support CUI Assets are in-scope.”

“Assets that cannot affect the confidentiality of CUI (e.g., unrelated IoT devices) are considered Out-of-Scope.”

Expanded explanation:

Data centers (A): If OSC CUI is stored or processed there, they are in-scope.

SIEM tools (C): Provide security monitoring of OSC networks — a clear Security Protection Asset.

MSP office (D): MSPs providing services that affect CUI are in-scope, including their management locations.

Smoke detector (B): Despite being network-connected, it does not interact with CUI or provide protective functions; it is explicitly out-of-scope.

Why the other options are in scope:

They either process, protect, or manage CUI directly.

Excluding them would improperly narrow the assessment boundary.
