CMMC-CCP Cyber AB Certified CMMC Professional (CCP) Exam Free Practice Exam Questions (2026 Updated)

According to the CMMC Assessment Process (CAP) and the C3PAO Authorization Requirements, every assessment conducted by a Certified Third-Party Assessment Organization (C3PAO) must undergo a formal Quality Management System (QMS) review before the results are finalized and uploaded to the eMASS (Enterprise Mission Assurance Support Service) or the SPRS (Supplier Performance Risk System).

The Quality Review Requirement: The CAP explicitly states that the C3PAO is responsible for the accuracy and integrity of the assessment findings. Before the Assessment Team Lead can formally submit the package, a person or team within the C3PAO (who was ideally not part of the active assessment team to ensure objectivity) must conduct an internal review. This review ensures that the evidence collected supports the " Met " or " Not Met " determinations and that all CMMC methodology requirements were followed.

Why other options are incorrect:

Option A: While there may be administrative costs associated with maintaining C3PAO status, paying a specific " per-submission fee " is not a mandatory procedural stepwithin the assessment lifecyclethat governs the validity of the results.

Option C: The Cyber AB (CMMC-AB) provides the platform and oversight, but a " forthcoming notification " is not a formal requirement in the CAP; the act of submission itself serves as the notification.

Option D: While a final briefing is a " best practice " and usually occurs during the " Post-Assessment " phase, the internal quality review (Option B) is the regulatory mandate that must be completed to ensure the C3PAO ' s certification of the results is valid and defensible.

C3PAO Quality Management System (QMS) Requirements: Outlines the necessity for internal validation of assessment packages to maintain accreditation.

Understanding the “Verify Evidence and Record Gaps” Activity in a CMMC Assessment

During aCMMC Level 2 Assessment, theAssessment Teamfollows a structured methodology toverify evidenceand determine whether theOrganization Seeking Certification (OSC)has met all required practices. One of the key activities in this process is " Verify Evidence and Record Gaps " , which ensures that the assessment findings accurately reflect any missing or inadequate compliance evidence.

Step-by-Step Breakdown:

✅1. Primary Intent: Identifying Gaps Between Required and Collected Evidence

TheAssessment Teamcompares the evidence provided by the OSC against theCMMC practice requirements.

If evidence ismissing, insufficient, or inconsistent, assessors mustdocument the gapand describe what is lacking.

This ensures that compliance deficiencies are clearly identified, allowing the OSC to understand what must be corrected.

✅2. How This Process Works in a CMMC Assessment

Assessorsreview collected documentation, system configurations, policies, and interview responses.

They verify that the evidencematches the expected implementationof a practice.

If gaps exist, they arerecordedfor discussion and potential remediation before assessment completion.

✅3. Why the Other Answer Choices Are Incorrect:

(A) Map test and demonstration responses to CMMC practices.❌

Incorrect:While mapping evidence to CMMC practices is part of the assessment, theprimary intentof the " Verify Evidence and Record Gaps " step is toidentify deficiencies, not just mapping responses.

(B) Conduct interviews to test process implementation knowledge.❌

Incorrect:Interviews are a method used during evidence collection, but they arenot the primary focusof the verification and gap analysis step.

(C) Determine the one-to-one relationship between a practice and an assessment object.❌

Incorrect:The assessment teamreviews multiple sources of evidencefor each practice, and some practices require multiple assessment objects. The goal isnot a strict one-to-one mappingbut rathera holistic validation of compliance.

Final Validation from CMMC Documentation:

TheCMMC Assessment Process Guidestates that " Verify Evidence and Record Gaps " is the step where assessorscompare expected evidence against what has been provided and document discrepancies. This ensurestransparent assessment findings and remediation planning.

Thus, the correct answer is:

D. Identify and describe differences between what the Assessment Team required and the evidence collected.

The core protection principle for OSC-provided assessment information (including PCI/CUI, assessment workpapers/notes, and the assessment results package ) is confidentiality / non-disclosure . The CMMC rules require assessors not to disclose OSC information outside the assessment participants, except as required by law. For example, CMMC assessor requirements include not sharing information about an OSC obtained during pre-assessment and assessment activities with anyone not involved in that specific assessment .

For retention, the authoritative requirement in the CMMC Program rule (32 CFR Part 170) is that assessment-related records are maintained for six (6) years , unless disposition is otherwise authorized by the CMMC PMO. This record set includes assessment materials and working papers generated during Level 2 certification assessments, and it also includes contractual agreements.

Important correction to the multiple-choice options: none of the answers list the official six-year retention period. The best available option is therefore B because it correctly captures the required confidentiality/non-disclosure principle—but the “ 3 years ” duration in the option does not match the official CMMC v2.0 retention requirement (which is 6 years ).

===========

The correct answer is B because the CUI banner marking is a document-level marking and must reflect the CUI contained in the document, not merely the CUI on one page or only the cover. The CUI marking rule states that CUI banner markings may include the CUI control marking, category or subcategory markings, and limited dissemination controls. It also states that CUI Specified category or subcategory markings that pertain to the information in the document must be included in the banner marking. Most importantly, the content of the CUI banner marking must apply to the whole document, inclusive of all CUI within the document, and must be the same on each page of the document that includes CUI. Option A uses “highest level” language, which is more characteristic of classified-information marking logic and is not the cleanest CUI rule. Options C and D are wrong because they confine special category/subcategory marking to the cover page or only selected pages, while the CUI banner marking operates at the document level. Reference/topics: CUI Registry, CUI banner marking, CUI category/subcategory markings, CUI Specified.

Understanding the CMMC Level 2 Assessment Process

When anOrganization Seeking Certification (OSC)engages aCertified Third-Party Assessment Organization (C3PAO)to conduct aCMMC Level 2 Assessment, anAssessment Planis developed to outline the scope, methodology, and logistics of the assessment.

Who Signs Off on the Assessment Plan?

According to theCMMC Assessment Process (CAP) Guide, theAssessment Plan must be formally agreed upon and signed off by:

Lead Assessor– The individual responsible for overseeing the execution of the assessment.

C3PAO (Certified Third-Party Assessment Organization)– The entity conducting the assessment.

Why " C. Lead Assessor and C3PAO " is Correct?

TheLead Assessorensures that theAssessment Plan aligns with CMMC-AB and DoD requirements, including methodology, objectives, and evidence collection.

TheC3PAOprovides organizational approval, confirming that the assessment is conducted according toCMMC-AB rules and contractual agreements.

Why Other Answers Are Incorrect?

A. OSC and Sponsor (Incorrect)

TheOSC (Organization Seeking Certification)is involved in planning but does not sign off on the plan.

Asponsoris not part of the sign-off process in CMMC assessments.

B. OSC and CMMC-AB (Incorrect)

TheOSCdoes not formally approve theAssessment Plan—this responsibility belongs to the assessment team.

TheCMMC-ABdoes not sign off on individualAssessment Plans.

D. C3PAO and Assessment Official (Incorrect)

" Assessment Official " isnot a defined rolein the CMMC assessment process.

TheC3PAOis involved, but it must be theLead Assessorwho signs off, not an unspecified official.

Conclusion

The correct answer isC. Lead Assessor and C3PAO.

TheLead Assessorensures assessment integrity, while theC3PAOprovides official authorization.

What Does the Practice of Professionalism Require in the CMMC Code of Professional Conduct?

TheCMMC Code of Professional Conduct (CoPC)sets ethical and professional standards forCertified CMMC Assessors (CCAs) and Certified CMMC Professionals (CCPs).Professionalismrequireshonesty and integrity in all CMMC-related activities.

Step-by-Step Breakdown:

✅1. Professionalism Requires Ethical Behavior

TheCoPC states that professionalismincludes:

Acting with integrityin all assessment-related activities.

Providing truthful and objective assessmentsof cybersecurity practices.

Avoiding deceptive or misleading claimsabout assessments or compliance.

✅2. Why the Other Answer Choices Are Incorrect:

(A) Do not copy materials without permission to do so❌

This falls underIntellectual Property (IP) protection, notProfessionalism.

(B) Do not make assertions about assessment outcomes❌

Assessorsmustprovide findings based on evidence. The rule is aboutnot making false or misleading claims, not about avoiding assertions altogether.

(D) Ensure the security of all information discovered or received❌

This falls underConfidentiality, notProfessionalism.

Final Validation from CMMC Documentation:

TheCMMC Code of Professional Conduct (CoPC)definesProfessionalism as requiring honesty and integrityin allCMMC-related activities.

Thus, the correct answer is:

✅C. Refrain from dishonesty in all dealings regarding CMMC.

DoDI 5200.48 specifies that Authorized Holders of CUI are responsible for applying appropriate CUI markings. An authorized holder is an individual who has lawful government purpose access to the information. This ensures that responsibility for correctly marking information rests with those who create or handle the material, not only with original classification authorities (which apply to classified information, not CUI).
