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

In the context of the Cybersecurity Maturity Model Certification (CMMC) 2.0, particularly at Level 2, organizations are required to implement stringent controls to protect Controlled Unclassified Information (CUI). This includes adhering to specific practices related to media protection and physical security.

Media Protection (MP):

MP.L2-3.8.1 – Media Protection:Organizations must protect (i.e., physically control and securely store) system media containing CUI, both paper and digital. This ensures that sensitive information is not accessible to unauthorized individuals.

Defense Innovation Unit

MP.L2-3.8.3 – Media Disposal:It is imperative to sanitize or destroy information system media containing CUI before disposal or release for reuse. This practice prevents potential data breaches from discarded or repurposed media.

Defense Innovation Unit

Physical Protection (PE):

PE.L2-3.10.2 – Monitor Facility:Organizations are required to protect and monitor the physical facility and support infrastructure for organizational systems. This includes ensuring that areas where CUI is processed or stored are secure and access is controlled.

Defense Innovation Unit

Application to the Scenario:

Given that the Organization Seeking Certification (OSC) operates within a shared, multi-tenant building and utilizes a common conference room for assessments, the following considerations are crucial:

Reviewing the Evidence File:The evidence file, which contains CUI, should be reviewed on a secure, authorized device to prevent unauthorized access or potential data leakage.

Printing the Evidence File:If printing is necessary, ensure that the printer is located in a secure area, and the printed documents are retrieved immediately to prevent unauthorized viewing.

Making Notes:Any notes derived from the evidence file should be treated with the same level of security as the original document, especially if they contain CUI.

Disposal of Printed Materials:After the assessment, all printed materials and notes containing CUI must be destroyed using a cross-cut shredder. Cross-cut shredding ensures that the information cannot be reconstructed, thereby maintaining confidentiality.

Options A and D are inadequate as they involve leaving sensitive information in unsecured locations, which violates CMMC physical security requirements. Option B, while secure in terms of digital handling, does not address the proper disposal of any physical copies that may have been made. Therefore, Option C is the best practice, aligning with CMMC 2.0 guidelines by ensuring that all physical media containing CUI are properly reviewed, securely stored during use, and thoroughly destroyed when no longer needed.

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-AssessmentCMMC 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.

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).

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.

Official CMMC 2.0 Documentation ReferencesBreakdown of Answer ChoicesConclusionThecorrect 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.

Step 1: Understand the Assessor’s Role and Chain of ResponsibilityDuring a CMMC assessment, the assessor ispart of the team organized by a C3PAO (Certified Third-Party Assessment Organization). If the assessor determines thatevidence is insufficient or inadequate, they arenot authorizedto act independently in terms of halting or postponing the assessment.

Source Reference: CMMC Assessment Process (CAP) v1.0 – Section 3.5.4 & 3.5.6

"If the Assessment Team identifies gaps in the sufficiency or adequacy of evidence, they must work with the Lead Assessor and C3PAO to determine the appropriate course of action."

The C3PAO is responsible for overseeing the assessment lifecycle.

If evidence isnot adequate, the assessor mustescalate within their organization(i.e., to the Lead Assessor or C3PAO point of contact) to:

Request clarifications from the OSC,

Determine if additional evidence can be requested,

Decide on continuing, pausing, or modifying the assessment schedule.

✅Step 2: Why Contacting the C3PAO Is the Correct Action

A. Notify the CMMC-AB✘ Incorrect. The Cyber AB (formerly CMMC-AB) isnot involved in operational aspectsof assessments. They do not manage day-to-day assessment decisions.

B. Cancel the assessment✘ Incorrect. An assessorcannot unilaterally cancelan assessment. Only theC3PAO, in consultation with all parties, may take such action.

C. Postpone the assessment✘ Incorrect. Postponements are logistical decisions that must be managed through theC3PAO, not an individual assessor.

❌Why the Other Options Are Incorrect

When an assessor determines that the evidence submitted by an OSC is inadequate or insufficient to meet a CMMC practice, thecorrect and required course of action is to consult with the C3PAO. The C3PAO will provide guidance or coordinate appropriate next steps.

Understanding CUI Protection ResponsibilitiesControlled 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.

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.

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.

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

CMMC Level 1applies toFederal Contract Information (FCI)systems.

Any system or device that is connected to an FCI-handling network is within the assessment scopebecause it canintroduce vulnerabilitiesinto the environment.

TheWi-Fi-enabled thermostat is connected to the FCI network, meaning it haspotential accessto sensitive contract-related data.

PerCMMC Scoping Guidance, this type of device is classified as aRestricted Information System (Restricted IS)—devices that do not store, process, or transmit FCI but areconnected to networks that do.

Restricted IS must be accounted for in the self-assessment scope to ensure they do not compromise security controls.

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.

What is Required in the CMMC Assessment Kickoff and Opening Briefing?Before starting aCMMC assessment, theLead Assessormust present anopening briefingto ensure that theOrganization Seeking Certification (OSC)understands the assessment process.

Step-by-Step Breakdown:✅1. Overview of the Assessment Process

The Lead Assessormust explain the CMMC assessment methodology, including:

Theassessment objectives and scope

How theassessment team will review security controls

What to expectduring interviews, testing, and document review

This ensurestransparency and alignmentbetween the assessors and the OSC.

✅2. Why the Other Answer Choices Are Incorrect:

(A) Gathering Evidence❌

Evidence collection is part of the assessment butnot the primary topic of the opening briefing.

(B) Review of the OSC's SSP❌

While theSSP is a key document, reviewing it is part of the assessment,not the kickoff briefing.

(D) Examination of the artifacts for sufficiency❌

Artifact review happens laterin the assessment process,not during the kickoff.

TheCMMC Assessment Process Guidestates that theopening briefing must include an overview of the assessment process, ensuring the OSC understands the expectations and methodology.

Final Validation from CMMC Documentation:Thus, the correct answer is:

✅C. Overview of the assessment process.

In the context of the Cybersecurity Maturity Model Certification (CMMC) 2.0, the remediation review process is a critical phase where identified deficiencies from an initial assessment are addressed. The Lead Assessor, representing a Certified Third-Party Assessment Organization (C3PAO), plays a pivotal role in this process.

Role of the Lead Assessor in Remediation Reviews:

Validation of Remediation Efforts:

Objective:Ensure that the Organization Seeking Certification (OSC) has effectively addressed and corrected all deficiencies identified during the initial assessment.

Process:The Lead Assessor reviews the evidence provided by the OSC to confirm that each previously unmet practice now meets the required standards. This involves examining updated policies, procedures, system configurations, and other relevant artifacts.

Delta Assessment Remediation Package Submission:

Definition:A delta assessment focuses on evaluating only the components or practices that were previously found non-compliant or deficient.

Responsibility:After validating the remediation efforts, the Lead Assessor compiles a remediation package that includes:

Detailed documentation of the deficiencies identified in the initial assessment.

Evidence of the corrective actions taken by the OSC.

Findings from the reassessment of the remediated practices.

Internal Quality Review:This remediation package is then submitted for the C3PAO's internal quality review process. The purpose of this review is to ensure the accuracy, completeness, and consistency of the assessment findings before finalizing the certification decision.

Rationale for Selecting Answer C:

Alignment with CMMC Assessment Process:The submission of a delta assessment remediation package for internal quality review is a standard procedure outlined in the CMMC Assessment Process. This step ensures that all remediated items are thoroughly evaluated and validated, maintaining the integrity of the certification process.

Clarification of Incorrect Options:

Option A:"Help OSC to complete planned remediation activities."

Explanation:The Lead Assessor's role is to assess and validate the OSC's compliance, not to assist in the implementation or completion of remediation activities. Providing such assistance could lead to a conflict of interest and compromise the objectivity of the assessment.

Option B:"Plan two consecutive remediation reviews for an OSC."

Explanation:The standard process involves conducting a single remediation review after the OSC has addressed the identified deficiencies. Planning multiple consecutive remediation reviews is not a typical practice and could indicate a lack of proper remediation planning by the OSC.

Option D:"Validate that practices previously listed on the POA&M have been removed on an updated Risk Assessment."

Explanation:While it's essential to ensure that deficiencies are addressed, the primary focus of the Lead Assessor during a remediation review is to validate the implementation of remediated practices. Updating the Risk Assessment is the responsibility of the OSC's internal risk management team, not the Lead Assessor.

Understanding Evidence Sufficiency in CMMC Level 2 AssessmentsDuring aCMMC Level 2 Assessment, theLead Assessormust determine whether the evidence collected for each practice issufficientto support an assessment finding. This aligns with theCMMC Assessment Process (CAP) Guide, which requires assessors to evaluate:

Examinations– Reviewing documents, configurations, and system records.

Interviews– Speaking with personnel to confirm implementation and understanding.

Testing– Observing security controls in action to validate effectiveness.

To determine whether evidence issufficient, the assessor ensures that it:

Directly supports the assessment objective.

Demonstrates that the practice is consistently implemented.

Can be independently verified.

Sufficiencyrefers to whetherenoughevidence has been collected to make an accurate determination about compliance.

Option A (Adequacy)is incorrect because adequacy relates tothe qualityof evidence, while sufficiency focuses on whetherenoughevidence exists.

Option C (Process Mapping)is incorrect because process mapping is used for understanding workflows but is not an assessment verification method.

Option D (Assessment Scope)is incorrect because defining the scope happensbeforeevidence collection, during the planning phase.

CMMC Assessment Process (CAP) Guide – Section 3.6 (Determining Sufficiency of Evidence)

CMMC Level 2 Assessment Guide – Evidence Collection and Evaluation

Why Option B (Sufficiency) is CorrectOfficial CMMC Documentation ReferencesFinal VerificationSince theLead Assessor is ensuring enough evidence is available to verify compliance, the correct answer isOption B: Sufficiency.

Understanding Policy Validation in CMMC AssessmentsDuring a CMMC assessment, policies must be evaluated based on:

Who has the authority to approve and enforce them

Whether they are current and implemented effectively

The validity of a policydoes not solely depend on the signatorybut rather onhow the organization assigns authority for policy creation, approval, and enforcement.

Some organizations assignauthority to a specific person, meaning anew signatory may be requiredwhen leadership changes.

Others assign authority to aposition/title(e.g., CISO, IT Director), in which casea new signature may not be requiredas long as the role remains responsible for policy enforcement.

The assessment teammust review the organization's policy management processto determine if the policy remains valid despite leadership turnover.

Key Considerations in Policy Validation:Thus,the correct answer is B, as additional research is needed to confirm whether the organization's policy is tied to the individual or the position.

A. The signatory is the authority to implement and enforce the policy, and since that person is no longer with the company, the policy is not valid.❌Incorrect. This assumes thatauthority is always tied to a person, which is not always the case. Some organizations delegate authorityto a position, not an individual.

C. The signatory does not validate or invalidate the policy. For the purpose of this assessment, ensuring that the policy is current and is being implemented by the individuals who are performing the work is sufficient.❌Incorrect. While implementation is crucial,the authority behind the policy must also be validatedper CMMC documentation requirements.

D. The authority to implement and enforce lies with the position, not the person. As long as that position's authority and responsibilities have not been removed from implementing that domain, it is still a valid policy.❌Incorrect. This assumes thatauthority is always assigned to a position, which is not universally true. More research is required to confirm this.

Why the Other Answers Are Incorrect

CMMC Assessment Process (CAP) Document– Outlines the importance of verifying the authority and enforcement of policies.

NIST SP 800-171 (3.12.1 - Security Policies and Procedures)– Requires that policies be maintained and enforced by appropriate personnel.

CMMC Official ReferencesThus,option B (More research on the company policy is needed) is the correct answer, as per official CMMC policy validation guidance.
