Cyber AB Updated CMMC-CCA Exam Questions and Answers by yazan

Applicable Requirement: CAP – Interview Guidance.

Why C is Correct: Interviews must be directed to personnel responsible for implementing, performing, or supporting practices to ensure accurate and objective evidence is collected.

Why Other Options Are Insufficient:

A: Yes/no questions do not provide sufficient evidence detail.

B: OSC personnel cannot ask themselves assessment questions; only assessors may conduct interviews.

D: Group interviews may be used in some cases, but CAP stresses targeted interviews for evidence reliability.

The CMMC Assessment Process (CAP) requires that when sensitive or proprietary materials are exchanged during an assessment, the OSC and the C3PAO should establish confidentiality protections through a Non-Disclosure Agreement (NDA).

Extract:

“OSC and C3PAOs are expected to execute a Non-Disclosure Agreement (NDA) to protect sensitive information such as proprietary, attorney-client privileged, or pre-patent materials shared during the assessment process.”

Thus, the NDA is the correct document.

The OSC is responsible for providing the scoping documentation before the assessment begins. The assessor validates the scoping documentation but does not create it on behalf of the OSC. If the OSC cannot provide scope documentation, the assessment cannot proceed.

Exact Extracts:

CMMC Scoping Guide: “The OSC must prepare and provide scoping documentation, including network diagrams, asset inventories, and SSP, prior to assessment.”

CMMC Assessment Guide: “The assessment team validates scoping documentation; it is not the responsibility of the C3PAO or assessor to create the OSC’s scope.”

Why other options are not correct:

A: Incorrect — assessment teams validate but do not generate scoping documents.

C: Joint creation is not allowed; OSC must own and prepare documentation.

D: Lead Assessor cannot create scope; must rely on OSC’s provided documentation.

A shared Internet connection indicates that Security Protection Assets (SPAs) are present and serving both the CUI environment and other parts of the enterprise. SPAs are always in-scope regardless of where they are located, because they provide security protections for CUI. Therefore, if documentation or diagrams show that the commercial and federal environments share a single Internet connection, the assessor must request access to the other building to confirm proper implementation and isolation.

Exact Extracts (from CMMC Assessor/Study documents):

“Security Protection Assets provide security functions or capabilities within the OSA’s CMMC Assessment Scope. Security Protection Assets are part of the CMMC Assessment Scope and are assessed against Level 2 security requirements that are relevant to the capabilities provided.”

“Contractor Risk Managed Assets are not required to be physically or logically separated from CUI Assets… If documentation or other findings raise questions about these assets, the assessor can conduct a limited check to identify deficiencies.”

“Separation… is required only for Out-of-Scope Assets. Isolation can be achieved… by implementing subnetworks with firewalls or other boundary protection devices.”

“The CMMC Assessment Scope includes all assets in the OSA’s environment that will be assessed… OSAs will be required to provide a network diagram of the CMMC Assessment Scope to facilitate scoping discussions during pre-assessment.”

“An OSC can obtain a Level 2 certification assessment for an entire enterprise network or for a specific enclave(s), depending upon how the CMMC Assessment Scope is defined…”

Why the other options are not correct:

A (locked cases): Physical movement of materials does not establish scope. Scoping is determined by CUI flow and security protection assets, not incidental observation of personnel activities.

B (underground passageway): Physical tunnels or building connections do not affect scope unless they result in shared IT/security functions.

D (HR location): HR is not a SPA because it does not provide security functions to protect CUI. Unless HR systems process or store CUI directly, they remain out of scope.
