Free Practice Questions for Cyber AB CMMC-CCP Exam

The correct answer isA. CMMC Assessment Reporting Requirementsbecause this document specifically outlines thestructured processthat Certified Third-Party Assessment Organizations (C3PAOs) must follow when conducting and reporting CMMC assessments.

Step-by-Step Breakdown:

Understanding the CMMC Assessment Process

TheLead Assessorbriefs the team on theassessment requirementsand theevaluation criteriabefore the assessment begins.

Throughout the assessment,findings summaries, practice ratings, and level recommendationsare documented and reported.

These findings are internally reviewed by theC3PAObefore they are formally submitted forquality review and final rating approval.

Key Document Stipulating Reporting Requirements: CMMC Assessment Reporting Requirements

This documentspecifically details how assessments must be reportedwithin theCMMC ecosystem.

It describes the structured process for assessment submission, internalC3PAO reviews, andquality checks by the CMMC-ABbefore an organization can receive a final certification decision.

It ensures thatresults are consistent, transparent, and aligned with DoD cybersecurity compliance expectations.

Why Other Options Are Incorrect:

B. DFARS 52.204-21 Assessment Reporting Requirements

This clause only specifiesbasic safeguardingof Federal Contract Information (FCI) but doesnotdictate the reporting process for CMMC assessments.

C. NIST SP 800-171 Revision 2 Assessment Reporting Requirements

WhileNIST SP 800-171 Rev. 2outlines security controls, it doesnotdefine how CMMC assessments must be conducted and reported.

D. DFARS Clause 252.204-7012 Assessment Reporting Requirements

This DFARS clause focuses onincident reportingandcyber incident response requirementsbut does not detail theCMMC assessment reporting process.

Official Reference:

CMMC Assessment Reporting Requirements, issued byThe Cyber ABandDoD, governs how C3PAOs must report assessment results.

CMMC Assessment Process (CAP)also outlines reporting workflows for certification.

Thus, theCMMC Assessment Reporting Requirementsdocument is the authoritative source that dictates the reporting procedures for CMMC assessments.

Understanding CUI Protection Responsibilities

Controlled Unclassified Information (CUI)is sensitive butnot classifiedinformation that requires protection underDoD Instruction 5200.48andDFARS 252.204-7012.

Theprimary responsibilityfor handling CUIis safeguardingit against unauthorized access, disclosure, or modification.

Why "D. Safeguarding" is Correct?

TheCUI Program (as per NARA and DoD)mandatessafeguarding measuresto protectCUI in both digital and physical forms.

CMMC 2.0 Level 2 (Advanced) practices align with NIST SP 800-171, which focuses on safeguarding CUIthrough access controls, encryption, and monitoring.

DFARS 252.204-7012requires DoD contractors to implementcybersecurity safeguardsto protect CUI.

Why Other Answers Are Incorrect?

A. Shielding (Incorrect)–Shieldingis not a cybersecurity term associated with CUI protection.

B. Governing (Incorrect)–Governing refers to policy-making, not direct protection.

C. Correcting (Incorrect)–Correcting implies remediation, but the primary responsibility is tosafeguardCUI proactively.

Conclusion

The correct answer isD. Safeguarding, asCUI protection focuses on implementing cybersecurity safeguards.

Step 1: Understanding AC.L1-3.1.22

AC.L1-3.1.22states:"Control information posted or processed on publicly accessible systems."

This control requires organizations toensure that FCI (Federal Contract Information) is not publicly postedor made accessible in an uncontrolled manner.

FCI must beprotected from unauthorized disclosure, even if it is not classified or CUI.

The term Adversarial Assessment is formally defined in DoD cyber terminology. It describes testing that evaluates a unit or system’s ability to perform its mission while facing simulated cyber threat activity representative of a real-world adversary.

Supporting Extracts from Official Content:

DoD Cybersecurity Test and Evaluation Guidebook: “Adversarial Assessment: Test conducted to evaluate a unit’s ability to support its mission while withstanding cyber threat activity representative of an actual adversary.”

Why Option D is Correct:

A penetration test is narrower and focuses on identifying vulnerabilities.

Black hat testing is not an official DoD or CMMC term.

Red cell assessment refers more broadly to force-on-force exercises and is not the term used in CMMC/governing DoD definitions.

Interview Selection in CMMC Assessments

During aCMMC assessment, theLead Assessormust work with theOrganization Seeking Certification (OSC)to select personnel for interviews. The goal is to:

✅Verify that personnel understand andperform security-related practices.

✅Ensure that individuals canexplain how they implement CMMC requirements.

✅Gain insight intoactual cybersecurity operationsrather than just documented policies.

The best interviewees are those whodirectly engage with security practicesand canclearly explain how they perform their duties.

Why "Providing Clarity and Understanding" Is Key

CMMC assessmentsrely on interviewsto validate that security practices areimplemented effectively.

Themost valuable intervieweesare those who canexplainhow security measures are appliedin day-to-day operations.

CMMC Assessment Process (CAP)emphasizes that assessors should speak tothose actively involved in security practicesrather than just senior management or policy owners.

Thus,option D is the correct choicebecause the Lead Assessor should prioritizeinterviewing personnel who can clearly explain how CMMC practices are implemented.

Why the Other Answers Are Incorrect

A. Have a security clearance.

❌Incorrect.Security clearance is not a requirementfor CMMC assessments. The focus is onpractical implementation of security controls, not classified work.

B. Be a senior person in the company.

❌Incorrect. Senior executives may not be involved in theactual implementation of security controls. The best interviewees are those whoperform the work, not just oversee it.

C. Demonstrate expertise on the CMMC requirements.

❌Incorrect. Whileunderstanding CMMC is important, expertise alonedoes not guarantee practical knowledgeof security controls. The key is thatinterviewees must provide clarity on how they perform security tasks.

CMMC Official References

CMMC Assessment Process (CAP) Document– Guides interview selection based on personnel who perform security functions.

NIST SP 800-171 & CMMC 2.0– Emphasize that cybersecurity controls must beactively implemented, not just documented.

Thus,option D (Provide clarity and understanding of their practice activities) is the correct answeras per official CMMC assessment guidelines.
