Who is responsible for ensuring that subcontractors have a valid CMMC Certification?

  1. CMMC-AB
  2. OUSDA&S
  3. DoD agency or client
  4. Contractor organization

Answer(s): D

Explanation:

Step 1: Responsibility for Subcontractor Compliance

The prime contractor (contractor organization)is responsible for ensuring thatits subcontractorshave the requiredCMMC certification levelbefore engaging them inDoD contracts that involve FCI or CUI.

This requirement is enforced throughflow-down clausesinDFARS 252.204-7021, which mandates that subcontractors handlingCUImeet the necessaryCMMC Level 2 or Level 3 requirements.


Reference:

DFARS 252.204-7021(CMMC Compliance)

CMMC 2.0 Program Documentation

Step 2: Why Other Answer Choices Are Incorrect

A . CMMC-AB (Incorrect):

TheCyber AB (formerly CMMC-AB)is responsible foraccrediting C3PAOs and managing the assessment process, but it does not enforce subcontractor compliance.

B . OUSDA&S (Incorrect):

TheOffice of the Under Secretary of Defense for Acquisition & Sustainment (OUSD A&S)develops and overseesCMMC policy, but it does not monitor or enforce individual subcontractor compliance.

C . DoD agency or client (Incorrect):

While theDoD sets CMMC requirements, it relies onprime contractors to ensure compliance among their subcontractorsthrough contract flow-down requirements.

Final Confirmation of correct answers:

Prime contractors must ensure their subcontractors have the required CMMC certification level to handle FCI or CUI.

Thus, the correct answer is:D. Contractor organization



How many domains does the CMMC Model consist of?

  1. 14 domains
  2. 43 domains
  3. 72 domains
  4. 110 domains

Answer(s): A

Explanation:

Step 1: Understanding CMMC Domains

TheCMMC Model consists of 14 domains, which are based on theNIST SP 800-171 control familieswith additional cybersecurity practices.

Eachdomaincontainspractices and processesthat define cybersecurity requirements for organizations seeking CMMC certification.

Step 2: List of 14 CMMC Domains

Access Control (AC)

Asset Management (AM)(Introduced in CMMC 2.0 for scoping guidance)

Audit and Accountability (AU)

Awareness and Training (AT)

Configuration Management (CM)

Identification and Authentication (IA)

Incident Response (IR)

Maintenance (MA)

Media Protection (MP)

Personnel Security (PS)

Physical Protection (PE)

Risk Management (RM)

Security Assessment (CA)

System and Communications Protection (SC)

Step 3: Why Other Answer Choices Are Incorrect

B . 43 domains (Incorrect):

The CMMC model does not have43 domains; this number is incorrect.

C . 72 domains (Incorrect):

There are72 practices in CMMC Level 2, but not72 domains.

D . 110 domains (Incorrect):

110 refers to the number of security controls in NIST SP 800-171, which aligns withCMMC Level 2, but these are controls, not domains.

Final Confirmation of correct answers:

The CMMC Model consists of 14 domains based on NIST SP 800-171 control families.

Thus, the correct answer is:A. 14 domains



During the assessment process, who is the final interpretation authority for recommended findings?

  1. C3PAO
  2. CMMC-AB
  3. OSC sponsor
  4. Assessment Team Members

Answer(s): A

Explanation:

According to the CMMC Assessment Process (CAP) and the roles defined within the CMMC Ecosystem, the responsibility for the final determination of assessment findings rests with the C3PAO (Certified Third-Party Assessment Organization).

While the Assessment Team (Lead Assessor and Assessor) performs the legwork--conducting interviews, examining documents, and testing mechanisms--the C3PAO is the legal entity contracted by the OSC (Organization Seeking Certification) to conduct the assessment and issue the recommendation for certification.

Role of the C3PAO: The C3PAO provides the quality assurance and oversight. Once the Assessment Team completes the draft findings, the C3PAO performs a quality or "peer" review to ensure the findings are consistent with CMMC requirements. They hold the final authority over the Recommended Finding (Met, Not Met, or N/A) before it is uploaded to the eMASS (Enterprise Mission Assurance Support Service) or the designated DoD database.

Role of the Cyber AB (formerly CMMC-AB): The Board provides the accreditation for the C3PAOs and manages the ecosystem, but they do not participate in individual assessments or overrule specific technical findings of an assessment unless there is a formal appeal or ethics complaint.

Role of the Assessment Team Members: They collect evidence and make initial determinations, but their findings are subject to the C3PAO's internal quality management system (QMS) review.

Role of the OSC Sponsor: The OSC is the entity being assessed; they have no authority over the interpretation of findings, though they may provide additional evidence during the remediation period.

Reference Documents:

CMMC Assessment Process (CAP) v1.0: Section on "Phase 3: Conduct Assessment" and "Phase 4:

Reporting Results," which details the C3PAO's responsibility for the final package.

C3PAO Authorization Requirements: Outlines the requirement for a quality management review of all assessment findings by the C3PAO before submission to the DoD.



An OSC receives an email with "CUI//SP-PRVCY//FED Only" in the body of the message Which organization's website should the OSC go to identify what this marking means?

  1. NARA
  2. CMMC-AB
  3. DoD Contractors FAQ page
  4. DoD 239.7601 Definitions page

Answer(s): A

Explanation:

Understanding CUI Markings and the Role of NARA

What Does "CUI//SP-PRVCY//FED Only" Mean?

The email containsControlled Unclassified Information (CUI)withspecific categories and dissemination controls.

CUI//SP-PRVCY//FED Onlybreaks down as follows:

CUI Controlled Unclassified Information designation.

SP-PRVCYSpecifiedcategory forPrivacy Information(SP stands for "Specified").

FED Only Restriction forFederal Government use only(not for contractors or the public).

Who Maintains the Official CUI Registry?

TheNational Archives and Records Administration (NARA) oversees the CUI Programand maintains the officialCUI Registry(https://www.archives.gov/cui).

The CUI Registry providesdefinitions, marking guidance, and categoriesfor all CUI labels, including "SP-PRVCY" and dissemination controls like "FED Only."

Why NARA is the correct answer?

NARA is the governing body responsible for defining and managing CUI markings.

Any organization handling CUI shouldrefer to the NARA CUI Registryfor official marking interpretations.

DoD contractors and other organizationsmust comply with NARA guidelines when handling, marking, and disseminating CUI.

Clarification of Incorrect Options:

B . CMMC-AB­ TheCMMC Accreditation Bodymanages certification assessments butdoes not define or interpret CUI markings.

C . DoD Contractors FAQ Page­ The DoD may provide general contractor guidance, butCUI markings are governed by NARA, not an FAQ page.

D . DoD 239.7601 Definitions Page­ This refers to generalDoD acquisition definitions, butCUI categories and markings fall under NARA's authority.


Reference:

NARA CUI Registry(https://www.archives.gov/cui)

Final Answe r: A. NARA



Regarding the Risk Assessment (RA) domain, what should an OSC periodically assess?

  1. Organizational operations, business assets, and employees
  2. Organizational operations, business processes, and employees
  3. Organizational operations, organizational assets, and individuals
  4. Organizational operations, organizational processes, and individuals

Answer(s): C

Explanation:

TheRisk Assessment (RA) domainaligns withNIST SP 800-171 control family 3.11 (Risk Assessment)and is designed to help organizationsidentify, assess, and manage cybersecurity risksthat could impact their operations.

TheRA.3.144 practice(which is a CMMC Level 2 requirement) explicitly states:

"Periodically assess therisktoorganizational operations (including mission, functions, image, or reputation), organizational assets, and individualsresulting from the operation of organizational systems and the associated processing, storage, or transmission of CUI."

This means that OSCs (Organizations Seeking Certification) should regularly evaluate risks to:

Organizational operations(e.g., mission, business continuity, functions)

Organizational assets(e.g., data, IT systems, intellectual property)

Individuals(e.g., employees, contractors, customers affected by security risks)

Thus, the correct answer isC. Organizational operations, organizational assets, and individuals.

Why the Other Answers Are Incorrect

A . Organizational operations, business assets, and employees

Incorrect."Business assets"is not the correct terminology used in CMMC/NIST SP 800-171.
Instead,"organizational assets"is the proper term.

B . Organizational operations, business processes, and employees

Incorrect."Business processes"is not a part of the formal risk assessment requirement. The correct scope includesorganizational assetsandindividuals, not just processes.

D . Organizational operations, organizational processes, and individuals

Incorrect.
While processes are important,organizational assetsmust be considered in the assessment, not just processes.

CMMC Official Reference:

CMMC 2.0 Model (Level 2 - RA.3.144)­ Specifies that risk assessments must coverorganizational operations, organizational assets, and individuals.

NIST SP 800-171 (3.11.1)­ Reinforces the same risk assessment scope.

Thus,option C (Organizational operations, organizational assets, and individuals) is the correct answerbased on official CMMC risk assessment requirements.



In the CMMC Model, how many practices are included in Level 2?

  1. 17 practices
  2. 72 practices
  3. 110 practices
  4. 180 practices

Answer(s): C

Explanation:

How Many Practices Are Included in CMMC Level 2?

CMMC Level 2is designed to alignfullywithNIST SP 800-171, which consists of110 security controls (practices).

This meansall 110 practicesfrom NIST SP 800-171 are required for aCMMC Level 2 certification.

Breakdown of Practices in CMMC 2.0

CMMC Level

Number of Practices

Level 1

17 practices(Basic Cyber Hygiene)

Level 2

110 practices(Aligned with NIST SP 800-171)

Level 3

Not yet finalized but expected to exceed 110

Since CMMC Level 2 mandatesall 110 NIST SP 800-171 practices, the correct answer isC. 110 practices.

Why the Other Answers Are Incorrect

A . 17 practices

Incorrect.17 practicesapply only toCMMC Level 1, not Level 2.

B . 72 practices

Incorrect. There is no CMMC level with72 practices.

D . 180 practices

Incorrect. CMMC Level 2only requires 110 practices, not 180.

CMMC Official Reference:

CMMC 2.0 Model­ Confirms thatLevel 2 includes 110 practicesaligned withNIST SP 800-171.

NIST SP 800-171 Rev. 2­ Outlines the110 security controlsrequired for handlingControlled Unclassified Information (CUI).

Thus,option C (110 practices) is the correct answer, as per official CMMC guidance.



The Audit and Accountability (AU) domain has practices in:

  1. Level 1.
  2. Level 2.
  3. Levels 1 and 2.
  4. Levels 1 and 3.

Answer(s): B

Explanation:

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 1Incorrect

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

B . Level 2Correct

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 2Incorrect

Level 1 does not requireaudit and accountability practices.

D . Levels 1 and 3Incorrect

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

Official Reference 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.



A Level 2 Assessment was conducted for an OSC, and the results are ready to be submitted. Prior to uploading the assessment results, what step MUST the C3PAO complete?

  1. Pay an assessment submission fee.
  2. Complete an internal review of the results.
  3. Notify the CMMC-AB that submission is forthcoming.
  4. Coordinate a final briefing between the Lead Assessor and the OSC.

Answer(s): B

Explanation:

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.

Reference Documents:

CMMC Assessment Process (CAP) v1.0: Section on "Phase 4: Reporting Results," specifically the sub- section on C3PAO Quality Assurance Review.

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