Cyber AB CMMC-CCP Questions Answers

Understanding C3PAO Requirements

ACertified Third-Party Assessment Organization (C3PAO)is an entityauthorized by the CMMC Accreditation Body (CMMC-AB)to conductCMMC Level 2 Assessmentsfor organizations handlingControlled Unclassified Information (CUI).

Key Requirements for a C3PAO to Conduct Assessments:

✔Must be authorized by CMMC-AB before conducting assessments.

✔Must meet CMMC-AB and DoD cybersecurity and process requirements.

✔Must comply with ISO/IEC 17020 standards for inspection bodies.

✔Must undergo a rigorous vetting process, including cybersecurity verification.

Why is the Correct Answer "D" (A C3PAO must be authorized by CMMC-AB before being able to conduct assessments)?

A. An authorized C3PAO must meet some DoD and all ISO/IEC 17020 requirements → Incorrect

C3PAOs must comply with CMMC-AB authorization requirementsbefore performing assessments.

While they must align withISO/IEC 17020, they donotnecessarily meet all requirements upfront.

B. An accredited C3PAO must meet all DoD and some ISO/IEC 17020 requirements → Incorrect

C3PAOs are not accredited by DoD; they areauthorized by CMMC-ABto perform assessments.

Accreditation follows full compliance with CMMC-AB and ISO/IEC 17020 requirements.

C. A C3PAO must be accredited by DoD before being able to conduct assessments → Incorrect

The DoD does not directly accredit C3PAOs—CMMC-AB is responsible forauthorization and oversight.

D. A C3PAO must be authorized by CMMC-AB before being able to conduct assessments → Correct

CMMC-AB grants authorization to C3PAOs, allowing them to perform assessmentsonly after meeting specific requirements.

CMMC 2.0 References Supporting This Answer:

CMMC-AB Certified Third-Party Assessment Organization (C3PAO) Guidelines

States thatC3PAOs must receive CMMC-AB authorization before conducting assessments.

CMMC 2.0 Assessment Process (CAP) Document

Specifies that onlyC3PAOs authorized by CMMC-AB can conduct official CMMC assessments.

ISO/IEC 17020 Compliance for C3PAOs

Defines theinspection body requirements for C3PAOs, which must be met for accreditation.

According to the CMMC Model and Assessment Guides, specifically the rules governing Plan of Action and Milestones (POA & M) and the remediation period, an Organization Seeking Certification (OSC) is allowed a limited opportunity to remediate certain "Not Met" practices to achieve a "Met" status without failing the assessment entirely.

Here is the breakdown based on CMMC Ecosystem protocols:

The 180-Day POA & M Rule: CMMC Level 2 allows for the use of POA & Ms for specific practices, provided they are not high-priority items (typically 5-point values in the scoring methodology). If an OSC has "Not Met" practices that are eligible for a POA & M, they have up to 180 days to remediate them.

The Remediation Period (Assessment Closeout): During the assessment process itself, there is a "remediation period" (often referred to within the 1-90 day window depending on the specific C3PAO methodology and the CMMC assessment process) where an OSC can fix minor issues identified by the assessor before the final report is submitted.

Eligibility Criteria: The question states there are 15 practices "Not Met." While this is a high number, the CMMC rule does not automatically disqualify an OSC based solely on thequantityof practices, but rather thetype(weight) of the practices and the resulting score. To be eligible for a conditional "Met" (via POA & M), the OSC must achieve a minimum score (often 80% of the total points) and none of the "Not Met" practices can be those designated as mandatory "Met" (no POA & M allowed) in the CMMC rule.

Why "C" is correct: Because we do not know the specific weights of the 15 "Not Met" practices or the total score, we cannot definitively say theywillbe remediated (A) or that they areineligible(B). However, under the CMMC assessment framework, the OSC may be eligible to enter a remediation phase or utilize a POA & M to bridge the gap, provided they meet the scoring threshold and the specific practices allow for it.

Reference Documents:

CMMC Assessment Process (CAP): Defines the phases of assessment including the "Remediation Period."

32 CFR Part 170 (CMMC Program Rule): Outlines the specific requirements for POA & Ms, the 180-day timeline, and the scoring parameters required to be eligible for a Conditional Certification.

The correct document is a Non-Disclosure Agreement (NDA) , because its specific purpose is to restrict a receiving party from disclosing sensitive or confidential information to unauthorized parties. In the official CMMC Assessment Process (CAP) v2.0 , NDAs are called out directly as a required element of the contracting relationship for a Level 2 certification assessment.

CAP v2.0 states that the C3PAO and the OSC must execute a written contractual agreement for the assessment and then specifies that “A mutual non-disclosure agreement (NDA) between the parties shall be incorporated into the contractual agreement or negotiated and executed in a separate document (e.g., stand-alone NDA, master services agreement, etc.).”

This is important because CMMC assessments can involve access to highly sensitive organizational information, including details about system architectures, security implementations, and potentially CUI handling processes. The CAP’s NDA requirement supports controlling dissemination of that information and reinforces the broader confidentiality expectations placed on assessment participants.

While an “assessment agreement” or generic “legal agreement” might contain confidentiality clauses, CAP v2.0 explicitly identifies the NDA instrument (either embedded or standalone) as the mechanism to protect information exchanged during the assessment engagement. Therefore, the best answer—consistent with CMMC v2.0 official process documentation—is D (Non-disclosure agreement) .

CMMCLevel 1focuses onbasic cyber hygieneand includes17 practicesderived fromNIST SP 800-171 Rev. 2butonly covers the protection of Federal Contract Information (FCI)—not Controlled Unclassified Information (CUI).

UnlikeLevel 2, which aligns fully withNIST SP 800-171,Level 1 does not require third-party certificationand can beself-assessedby the organization.

Domains Covered in a Level 1 Self-Assessment

CMMC Level 1 practices fall underthree specific domains:

Access Control (AC)– Ensures that only authorized individuals can access FCI.

Physical Protection (PE)– Protects physical access to systems and facilities storing FCI.

Identification and Authentication (IA)– Verifies the identity of users accessing systems containing FCI.

These domains focus on foundational security controls necessary toprotect FCI from unauthorized access.

Official CMMC 2.0 Documentation References

CMMC Model v2.0states thatLevel 1 includes only 17 practicesmapped toNIST SP 800-171requirements specific toAccess Control (AC), Physical Protection (PE), and Identification and Authentication (IA).

CMMC Assessment Guide, Level 1confirms thatRisk Management (RM) and Media Protection (MP) are not included in Level 1, as they pertain to more advanced security measures needed for handlingCUI (Level 2).

Breakdown of Answer Choices

A. Access Control (AC), Risk Management (RM), and Media Protection (MP)→ Incorrect.Risk Management (RM) and Media Protection (MP) are Level 2 domains.

B. Risk Management (RM), Access Control (AC), and Physical Protection (PE)→ Incorrect.Risk Management (RM) is not part of Level 1.

C. Access Control (AC), Physical Protection (PE), and Identification and Authentication (IA)→Correct.These are thethree domains covered in CMMC Level 1 self-assessments.

D. Risk Management (RM), Media Protection (MP), and Identification and Authentication (IA)→ Incorrect.Risk Management (RM) and Media Protection (MP) are Level 2 domains.

Conclusion

Thecorrect answer is C. Access Control (AC), Physical Protection (PE), and Identification and Authentication (IA), as these are theonly three domains included in a CMMC Level 1 Self-Assessmentaccording toCMMC 2.0 documentation and NIST SP 800-171 mapping.
