Cyber AB CMMC-CCA Exam Dumps

MA.L2-3.7.1 (Perform Maintenance) requires that maintenance activities and risks associated with outdated or unsupported systems be managed. Unsupported systems create a security risk if not mitigated, particularly when they process CUI.

Extract:

''Maintenance must be performed and documented to ensure continued secure operation. When systems cannot be updated or patched due to technical limitations, the OSC must implement and document risk mitigation strategies.''

Because the OSC has not demonstrated risk management for the outdated OT system, the practice is NOT MET.

The assessor must first confirm facts with the OSC before making a determination. It is possible the technician has been granted temporary authorized access, in which case the situation may not be a violation. Therefore, the correct next step is to ask the OSC about the technician's authorization.

Exact Extracts:

PE.L2-3.10.3: ''Escort visitors and monitor visitor activity.''

Assessment Guide: ''Assessors should confirm with the OSC whether individuals observed are classified as visitors or authorized personnel before determining compliance.''

''Findings must be validated with OSC-provided evidence or clarification.''

Why other options are not correct:

A: Cannot mark as MET without verifying the technician's status.

B: Inappropriate --- assessors do not direct OSC personnel or vendors.

C: Cannot mark as NOT MET without first confirming authorization.

If an asset processes or generates CUI, it is a CUI Asset by definition, regardless of whether it is also part of a test lab or claimed as a Specialized Asset. Specialized Asset handling applies only when the asset does not process, store, or transmit CUI. Since the workstation outputs CUI, it must be assessed fully against CMMC practices.

Exact extracts:

''CUI Assets are those that process, store, or transmit CUI.''

''Specialized Assets... do not process, store, or transmit CUI.''

''If a Specialized Asset processes CUI, it must be categorized as a CUI Asset and is assessed against all applicable practices.''

Why the other options are incorrect:

B: The issue is not with the SSP practice; it is with misclassification of an asset.

C/D: Risk-based treatment applies only to Specialized Assets without CUI, which is not the case here.

Applicable Requirement (CAP -- Scoping and Evidence Validation): When inconsistencies arise about the environment, assessors are required to examine objective artifacts that define boundaries, such as network diagrams and system architecture documentation.

Why A is Correct: Network diagrams objectively show whether systems are hosted on-premises or involve ESPs (cloud, MSSPs, hosting providers). Reviewing them avoids ambiguity from inconsistent verbal descriptions.

Why Other Options Are Insufficient:

B: Interviewing another OSC representative may add to confusion rather than resolve it.

C: Interconnection agreements confirm ESP relationships but do not resolve whether the OSC has on-prem or hybrid environments.

D: Contacting ESPs directly is not part of the assessment process; OSC must provide evidence.

The CMMC Assessment Process emphasizes the importance of confidentiality and non-attribution in interviews to ensure OSC personnel provide candid, accurate information. Interviewees may give shallow or evasive answers if they fear attribution. Assuring confidentiality and non-attribution improves the quality and reliability of responses.

Exact extracts:

''The assessment team must ensure confidentiality and non-attribution during interviews.''

''Responses should be validated against evidence, but the quality of input depends on establishing a safe environment for candor.''

''Non-attribution is critical to elicit detailed and honest responses.''

Why the other options are incorrect:

A: Training matrices identify who is trained, not who should be interviewed.

C: NDAs are not a CCA responsibility --- they are contractual, not assessment requirements.

D: Mapping to artifacts is part of correlation after interviews, but does not solve the problem of poor interview responses.
