CMMC CMMC-CCP Syllabus Exam Questions Answers

When preparing forCMMC compliance, organizations must ensure that theirnetwork configurations align with required cybersecurity controls. Ifnetwork administratorsdisagree on certain configurations, the mostobjective and accurateway to resolve the disagreement is by referencingofficial CMMC guidanceandNIST SP 800-171 requirements, which form the foundation of CMMC Level 2.

Step-by-Step Breakdown:

CMMC Assessment Guides as the Primary Reference

TheCMMC Assessment Guides (Level 1 & Level 2)provide clearinterpretationsof security practices.

Theyexplain how each practice should be implemented and assessedduring certification.

NIST SP 800-171 as the Compliance Baseline

CMMC Level 2is based directly onNIST SP 800-171, which outlines the110 security controlsrequired for protectingControlled Unclassified Information (CUI).

Network configurations must complywith NIST-defined security requirements, including:

Access Control (AC) – Ensuring least privilege principles.

Audit and Accountability (AU) – Logging and monitoring network activity.

System and Communications Protection (SC) – Secure network design and encryption.

Why the Other Answer Choices Are Incorrect:

(A) Consult with the CEO of the company:

ACEO is not necessarily a cybersecurity expertand may not be familiar with CMMC technical requirements.

Technical compliance decisions should be based onCMMC and NISTframeworks, not executive opinions.

(C) Go with the network administrator ' s ideas with the least stringent controls:

Choosingless stringent controls increases security riskand could lead toCMMC non-compliance.

(D) Go with the network administrator ' s ideas with the most stringent controls:

While security is important,more stringent controlsmay introduceoperational inefficienciesorunnecessary coststhat are not required for compliance.

The correct approach is to implement what is required by CMMC and NIST SP 800-171, no more and no less.

Final Validation from CMMC Documentation:

TheCMMC Assessment GuidesandNIST SP 800-171 Rev. 2areofficial sourcesthat provide the most reliable guidance on compliance.

CMMC Level 2 is entirely based on NIST SP 800-171, making it the definitive source for resolving security disagreements.

Thus, the correct answer is:

B. Consult the CMMC Assessment Guides and NIST SP 800-171.

The correct answer is D because the question asks what is involved in all assessment methods, not what defines a single assessment method. Options A, B, and C describe the three individual assessment methods. Option A describes Test, where assessment objects are exercised under specified conditions and actual behavior is compared with expected behavior. Option B describes Interview, where discussions are held with personnel to clarify implementation and locate evidence. Option C describes Examine, where artifacts, specifications, mechanisms, or records are reviewed, inspected, studied, or analyzed. The common purpose across all three is to support a determination about whether the safeguard exists, functions correctly, is complete, and is capable of supporting the required security outcome. NIST SP 800-171A explains that assessment methods are used to facilitate understanding, achieve clarification, or obtain evidence, and that the assessment process gathers information and produces evidence to determine security requirement effectiveness. Therefore, D captures the cross-method assessment purpose, while A, B, and C each capture only one method. Reference/topics: assessment methods, Examine/Interview/Test, assessment objectives, evidence-based determination.

DFARS clause 252.204-7012 establishes the safeguarding of Covered Defense Information (CDI), which aligns with CUI categories. The clause specifies that the DoD is responsible for determining whether information is Controlled Unclassified Information (CUI) and marking it accordingly before sharing it with contractors. Contractors do not make determinations about what constitutes CUI; they are responsible for safeguarding information once it is received and marked as CUI.

Background on Legacy Markings and CUI

Legacy markings refer to classification labels used before the implementation of the Controlled Unclassified Information (CUI) Program under DoD Instruction 5200.48.

Documents with legacy markings (such as “For Official Use Only” (FOUO) or “Sensitive But Unclassified” (SBU)) must be reviewed for re-marking or redaction to align with CUI requirements.

When Must Legacy Markings Be Updated?

If the document is retained internally (Answer A - Incorrect): Documents under DoD control do not require immediate re-marking unless they are being shared externally.

If the document is classified as Secret (Answer B - Incorrect): This question is about CUI, not classified information. Secret-level documents follow different marking rules under DoD Manual 5200.01.

If a document is being shared externally (Answer C - Correct):

According to DoD Instruction 5200.48, Section 3.6(a), organizations must review legacy markings before sharing documents outside the organization.

The document must be re-marked in compliance with the CUI Program before dissemination.

If the original document does not contain CUI (Answer D - Incorrect): The original source document ' s status does not affect the requirement to re-mark a derivative document if it contains CUI.

Conclusion

The correct answer is C: Documents with legacy markings must be re-marked or redacted when being shared outside the organization to comply with DoD CUI guidelines.
