Pass the Cyber AB CMMC CMMC-CCP Questions and answers with ExamsMirror

Under DFARS and CMMC requirements, the prime contractor is responsible for ensuring its subcontractors meet the required CMMC level. Neither the DoD, The Cyber AB, nor OUSD A&S directly manages subcontractor certification.

Supporting Extracts from Official Content:

DFARS 252.204-7021: “The contractor shall ensure that its subcontractors have the appropriate CMMC level certification for the information they will handle.”

Why Option D is Correct:

Compliance responsibility flows through the contractor supply chain.

CMMC-AB (The Cyber AB) accredits assessors but does not police subcontractors.

OUSD A&S sets policy, not enforcement at contract level.

DoD agencies only require compliance at award/contract oversight level.

===========

During aCMMC assessment, assessors rely on interviews to validate the implementation of cybersecurity practices within anOrganization Seeking Certification (OSC). Ensuringconfidentiality and non-attributionallows employees to speak freely without fear of retaliation or bias, leading to more accurate and candid responses.

Step-by-Step Breakdown:

CMMC Assessment Process and the Role of Interviews

TheCMMC Assessment Guide(Level 2) states thatinterviews are a key methodto verify compliance with security controls.

Employees may hesitate to provide truthful information if they fear negative consequences.

To obtain accurate information, assessors must create an environment where team members feel safe.

Ensuring Non-Attribution for Accurate Responses

DoD Assessment Methodologyhighlights thatinterviewees should remain anonymousin reports.

Non-attribution reduces the risk of OSC leadership influencing responses or retaliating against employees.

Employees are more likely to provideaccurateandhonestdescriptions of their responsibilities when confidentiality is guaranteed.

Why the Other Answer Choices Are Incorrect:

(A) Interview groups of people to get collective answers:

Group interviews may limit honest responses due topeer pressure or management presence.

Employees mayhesitate to contradictsupervisors or peers in a group setting.

(B) Understand that testing is more important than interviews:

While testing (e.g., reviewing logs, configurations, and security settings) is crucial, interviews providecontexton how security practices are implemented and followed.

Interviewscomplementtesting rather than being less important.

(D) Let team members know the questions prior to the assessment:

Advanced notice may allow employees toprepare rehearsed answers, which might not reflect actual practices.

This couldreduce the effectivenessof the interview process.

Final Validation from CMMC Documentation:

TheCMMC Assessment Process Guideand DoDAssessment Methodologyemphasize the importance of confidentiality in interviews to ensure accuracy.Non-attribution protects employees and ensures assessors get honest, unfiltered answers.

Thus, the correct answer is:

C. Ensure confidentiality and non-attribution of team members.

CMMC Level 2 requires full implementation of the 110 security requirements specified in NIST SP 800-171 Rev. 2, Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations. These practices form the foundation for safeguarding CUI across defense contractor systems.

NIST SP 800-53 is a broader catalog of security controls for federal systems, not specific to CUI in the defense contractor environment.

48 CFR 52.204-21 establishes basic safeguarding requirements for Federal Contract Information (FCI) and corresponds to CMMC Level 1.

DFARS 252.204-7012 defines safeguarding and incident reporting obligations but does not enumerate the specific security practices required.

Thus, Level 2 practices are aligned to NIST SP 800-171.

Reference Documents:

CMMC Model v2.0 Overview, December 2021

NIST SP 800-171 Rev. 2

ThePhysical Protection (PE) domaininCMMC 2.0 Level 1includes the requirementPE.L1-3.10.3, which mandates that organizationsescort visitors and monitor their activity.

Breaking Down the Scenario:

TheCMMC Assessment Teamarrives at the OSC.

Thereceptionist acknowledges their arrival but does not verify credentials or escort themto the appropriate location.

Failing to verify visitor identity and failing to escort them is a violation of PE.L1-3.10.3.

Analysis of the Given Options:

A. PE.L1-3.10.3: Escort visitors and monitor visitor activity→✅Correct

This requirement ensures that visitorsdo not have unsupervised access to sensitive areas.

The receptionistshould have checked credentials and escorted the assessment team.

B. PE.L1-3.10.5: Control and manage physical access devices→❌Incorrect

This requirement refers to managingkeys, access badges, and security devices, which isnot the issue in this scenario.

C. PS.L2-3.9.1: Screen individuals prior to authorizing access to organizational systems containing CUI→❌Incorrect

This control applies to personnel screeningsbefore granting access to CUI systems, not physical visitor access.

D. PS.L2-3.9.2: Ensure that organizational systems containing CUI are protected during and after personnel actions such as terminations and transfers→❌Incorrect

This requirement deals withoffboarding employees and ensuring they no longer have system access. It isnot relevant to visitor escorting.

Official References Supporting the Correct Answer:

CMMC 2.0 Level 1 - PE.L1-3.10.3 (Physical Protection)

Requires organizations toescort visitors and monitor visitor activityat facilities containingFCI or CUI.

NIST SP 800-171 Rev. 2, Control 3.10.3

States thatvisitors must be escorted and monitored at all timesto prevent unauthorized access.

Conclusion:

Since the receptionist failed to verify credentials and escort the visitors, this violatesPE.L1-3.10.3.

✅Correct Answer: A. PE.L1-3.10.3: Escort visitors and monitor visitor activity

TheAudit and Accountability (AU) domainis one of the14 familiesof security requirements inNIST SP 800-171 Rev. 2, which is fully adopted byCMMC 2.0 Level 2.

Analysis of the Given Options:

A. Level 1→Incorrect

CMMCLevel 1only includes17 basic FAR 52.204-21 safeguarding requirementsand does not coverAudit and Accountability (AU)practices.

B. Level 2→Correct

TheAU domain is required at Level 2, which aligns withNIST SP 800-171.

CMMC 2.0 Level 2includes110 security controls, among whichAU-related controlsfocus on logging, monitoring, and accountability.

C. Levels 1 and 2→Incorrect

Level 1 does not requireaudit and accountability practices.

D. Levels 1 and 3→Incorrect

CMMC 2.0 only has Levels 1, 2, and 3, andAU is present in Level 2, making Level 3 irrelevant for this answer.

Official References Supporting the Correct Answer:

NIST SP 800-171 Rev. 2 (Audit and Accountability - Family 3.3)

TheAU domainconsists of security controls3.3.1 – 3.3.8, focusing on audit log generation, retention, and accountability.

CMMC 2.0 Level 2 Practices (Aligned with NIST SP 800-171)

AU practices (Audit and Accountability) are only required at Level 2.

Conclusion:

TheAU domain applies only to CMMC 2.0 Level 2, making the correct answer:

✅B. Level 2.

Step 1: Define Roles – CCP and CCA

CCP (Certified CMMC Professional):

Entry-level certification in the CMMC ecosystem.

Supports assessment activities under the supervision of a CCA.

May assist in consulting roles outside of formal assessments.

CCA (Certified CMMC Assessor):

Certified tolead assessmentsunder the CMMC model.

Requiredfor conductingLevel 2 formal assessments.

Can be part of a C3PAO assessment team or lead it.

Source: CMMC Assessment Process (CAP) v1.0, Section 2.3 – Assessment Team Composition

“Level 2 assessments must be led by a Certified CMMC Assessor (CCA), who may be supported by one or more CCPs.”

✅Step 2: Citizenship Requirements

CAP v1.0 – Appendix B: Team Composition and Clearance Requirements

“All team members performing Level 2 assessments must be U.S. citizens when handling CUI, regardless of role.”

But forsupporting team members who do not handle CUIor inFCI-only scoping, there is no automatic exclusion based on citizenship.

So:

TheCCA leadsthe team.

CCPs can be team membersregardless of citizenship,unless restricted by contract or CUI handling needs.

❌Why the Other Options Are Incorrect

A. The CCP leads the Level 2 Assessment Team…

✘Incorrect. CCPscannot leadLevel 2 assessments.

B. The CCA leads… includes 3 CCP with US Citizenship.

✘Incorrect. Citizenship is requiredonly when handling CUI, not a universal requirement.

D. The CCP leads…

✘Again, CCPs donot have the authority to leadformal CMMC assessments.

Only aCertified CMMC Assessor (CCA)may lead aLevel 2 Assessment Team, and theymay include CCPs, evennon-U.S. citizens, if citizenship is not a requirement based on contractual or data sensitivity scope.

Anorganization seeking helpto address security gaps—such asphysical access control deficiencies—needs acertified professional who can provide implementation supportwithoutbeing involved in the actual CMMC assessment.

Role of a Registered Practitioner (RP)

A Registered Practitioner (RP)is a CMMC-certified individualwho provides consulting and implementation supportto organizations butdoes not perform assessments.

RPs work independently from C3PAOsand canassist in fixing gapsin security controlsbeforeorafteran assessment.

Since RPs are not assessors, they can provide direct remediation supportwithout any conflict of interest.

Why "B. RP of an Organization Not Part of the Assessment" is Correct?

The OSC needs assistance in implementing security controls(not assessment).

An RP is trained and authorized to provide remediation and advisory services.

Conflict of interest rules prevent the assessing C3PAO from providing implementation support.

Why Other Answers Are Incorrect?

A. CCA of the C3PAO performing the assessment (Incorrect)

ACertified CMMC Assessor (CCA)is responsible for conducting the assessmentonly.

TheC3PAO performing the assessment cannot also provide remediationdue to aconflict of interest.

C. Practitioner of the Organization Performing the Assessment LTP (Incorrect)

The assessmentLead Technical Practitioner (LTP)cannot provide remediation support for an OSC they are assessing.

D. DoD Contract Official of the Organization Performing the Assessment (Incorrect)

DoD Contract Officialsoversee contract compliance butdo not provide cybersecurity implementation support.

Conclusion

The correct answer isB. RP of an organization not part of the assessment, asonly independent RPs can assist with remediation and implementation support.

The CAP makes clear that evidence collected during the assessment is evaluated for both adequacy (does the evidence align with the requirement) and sufficiency (is there enough evidence to make a confident determination).

Supporting Extracts from Official Content:

CAP v2.0, Evidence Collection Guidance: “Evidence must be evaluated for adequacy… and for sufficiency, to ensure enough information is available to support the assessor’s determination.”

Why Option A is Correct:

Evidence is assessed based on two qualities only: adequacy and sufficiency.

“Thoroughness” and “appropriateness” are not official CAP terms for evidence evaluation.

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).

Understanding Ethical Responsibility in the CMMC Ecosystem

Ethics in theCMMC ecosystemis ashared responsibilitybetween theCMMC Accreditation Body (CMMC-AB)and itsmembers. TheCMMC-AB Code of Professional Conductoutlines ethical obligations forassessors, consultants, and other ecosystem participantsto ensure integrity, fairness, and professionalism.

Key Ethical Responsibilities Include:

CMMC-AB ensures the accreditation process remains fair, unbiased, and ethical.

CMMC ecosystem members (assessors, consultants, and organizations) are responsible for upholding ethical practices in assessments and implementations.

Ethical violations can result indisciplinary actions, revocation of certification, or legal consequences.

Why is the Correct Answer "CMMC-AB and Members of the CMMC Ecosystem" (C)?

A. DoD and CMMC-AB → Incorrect

TheDoD oversees CMMC implementation, butit is not responsible for the ethical conduct of CMMC assessments.

B. OSC and Sponsors → Incorrect

TheOrganization Seeking Certification (OSC)is responsible for compliance but doesnot oversee ethics in the CMMC ecosystem.

C. CMMC-AB and Members of the CMMC Ecosystem → Correct

Ethics is explicitly stated as ajoint responsibility of the CMMC-AB and its ecosystem membersin official CMMC guidance.

D. Members of the CMMC Ecosystem and Lead Assessors → Incorrect

Lead Assessors are part of theCMMC ecosystem, butCMMC-AB is the governing body responsible for ethical oversight.
