Free Cyber AB CMMC-CCP Practice Exam with Questions & Answers

In the context of a CMMC Level 2 Assessment, assessors must evaluate the " Institutionalization " of practices, which includes the review of Policies. The validity of a policy document depends on the Organization Seeking Certification (OSC) ' s internal governance and administrative procedures.

Internal Governance (The " Why " ): CMMC does not dictate exactlyhowa company must authorize its policies (e.g., whether a signature must be refreshed immediately upon a personnel change). Instead, the assessor must verify if the document is considered " active " and " authoritative " by the OSC’s own standards.

The Role of the Assessor: As per the CMMC Assessment Process (CAP) and CCP training materials, an assessor cannot unilaterally declare a policy invalid simply because a signatory has left. The assessor must perform " more research " (typically through Interviews or examining Supplemental Documents) to determine the OSC ' s internal rules for policy management.

If the OSC ' s " Policy on Policies " states that a signature is tied to the individual, the document may be expired.

If the OSC ' s rules state that the authority is tied to the role/position (which is common in most corporate governance), the policy remains in effect until it is formally rescinded or updated.

Distinction from other options:

Option A is too restrictive; it assumes a universal rule that doesn ' t exist in the CMMC framework.

Option C is incorrect because a signatory (or formal approval)isoften what gives a policy its " authoritative " status in an audit; ignoring it would be a failure of the Examine method.

Option D is a common business assumption, but an assessor must verify this via the OSC ' s own procedures rather than assuming it is true for every company.

Understanding the Definition of an Agreement in the CMMC-AB Code of Professional Conduct

TheCMMC-AB Code of Professional Conductdefines anagreementasany contract between two legal entities. This includes:

✔Contracts between an OSC and a C3PAOfor CMMC assessments.

✔Service agreements between cybersecurity providers and defense contractors.

✔Any formal, legally binding arrangement related to CMMC compliance.

Why is the Correct Answer " D. Agreement " ?

A. Union → Incorrect

Auniontypically refers to anorganization representing workersand is not used to describe acontractual relationship.

B. Accord → Incorrect

While anaccordcan mean an agreement, it isnot the standard legal term for a binding contractin CMMC documentation.

C. Alliance → Incorrect

Analliancerefers to astrategic partnership, but does not necessarily imply alegally binding contract.

D. Agreement → Correct

TheCMMC-AB Code of Professional Conductdefines anagreementas anylegally binding contract between two entities.

CMMC-AB Licensed Training and Assessment Provider Guidelines

Requires that all engagementsbe governed by a formal agreement (contract) between the parties.

DFARS and CMMC Certification Contracts

States thatOSC-C3PAO relationships must be formalized through a legal agreement.

The correct answer is C because a Licensed Partner Publisher is an ecosystem participant that produces or distributes approved CMMC-related learning or publishing content; it is not the same thing as an Organization Seeking Assessment or a Defense Industrial Base contractor pursuing a CMMC Level 3 certification status. CMMC certification levels apply to organizations handling FCI or CUI in connection with DoD contract performance, not to every training, publishing, or ecosystem-support organization. The CMMC Assessment Process describes CMMC as the DoD initiative for assessing and certifying conformance by companies and organizations in the Defense Industrial Base, specifically to safeguard CUI and FCI processed, stored, or transmitted during DoD contract performance. A publisher may need business validation, authorization, background checks, and approval by the CMMC Accreditation Body or authorized program entity, but requiring CMMC Level 3 certification would be misaligned with the role. Level 3 is an advanced contractor cybersecurity status, not a publishing-partner qualification.

During aCMMC assessment, organizations must provide evidence to demonstrate compliance with requiredpractices and processes. Assessors evaluate this evidence based on two key criteria:

Adequacy– Does the evidence meet the intent of the security requirement?

Sufficiency– Is there enough evidence to reasonably conclude that the practice/process is effectively implemented?

These principles are outlined in theCMMC Assessment Process Guide, which provides a structured approach for evaluating compliance.

Step-by-Step Breakdown:

✅1. Adequacy – Does the evidence fully meet the requirement?

Adequacyrefers to whether the evidence properly demonstrates that the security practice has been implemented as required.

Example: If an organization claims to enforceMulti-Factor Authentication (MFA), an assessor would checksystem configurations, login policies, and user authentication logsto confirm that MFA is actually in use.

✅2. Sufficiency – Is there enough evidence to support the claim?

Sufficiencymeans that there isenough supporting evidenceto prove compliance.

Example: If an organization providesonly one screenshot of an MFA login screen, that alone may not besufficient—additional logs, policies, and user records would help strengthen the case.

Why the Other Answer Choices Are Incorrect:

(B) Adequacy and Thoroughness❌

Thoroughnessis not a defined metric in CMMC evidence evaluation.

The focus is onwhether the evidence meets the requirement (adequacy)and if there isenough of it (sufficiency).

(C) Sufficiency and Thoroughness❌

Thoroughnessis not a recognized term in CMMC compliance validation.

Evidence must beadequate and sufficient, not just thorough.

(D) Sufficiency and Appropriateness❌

Appropriatenessis not a CMMC-defined criterion.

Thecorrect terms used in CMMC assessmentsareAdequacy(Does it meet the requirement?) andSufficiency(Is there enough proof?).

Final Validation from CMMC Documentation:

CMMC Assessment Process Guideexplicitly states that evidence must be evaluated based onadequacyandsufficiencyto confirm compliance with security practices.

The correct answer is C because the CMMC ecosystem treats conflicts of interest as both actual and perceived conflicts. The CMMC Code of Professional Conduct requires CMMC ecosystem members to avoid participating in any activity, practice, or transaction that could result in an actual or perceived conflict of interest. It also requires compliance with conflict-of-interest prohibitions and restricts CMMC ecosystem members from participating in a Level 2 certification process where their prior role or relationship could compromise objectivity.

A conflict of interest exists when professional judgment, independence, or impartiality could be affected, or reasonably appear to be affected, by another interest, relationship, duty, or prior activity. In CMMC, this is especially important because assessment credibility depends on independence between consulting and certification assessment functions. For example, an assessor or C3PAO that previously helped design, implement, or remediate the OSC’s cybersecurity program may have an actual or perceived conflict when later assessing that same OSC. Option A is incorrect because lack of transparency may contribute to a conflict issue, but it is not the definition. Option B is too broad because not every legal violation is a conflict of interest. Option D describes a disclosure problem, not a conflict of interest. Therefore, the best answer is C , a perceived or actual conflict.

===========

In the CMMC 2.0 framework, the " Advanced " level is synonymous with CMMC Level 2 . The model is designed to be cumulative , meaning each higher level incorporates the requirements of the level(s) below it.

Cumulative Structure : For an organization to achieve a Level 2 Certification, it must demonstrate that it meets all 17 practices from Level 1 (Foundational) plus the additional 93 practices introduced at Level 2, totaling 110 practices (aligned with NIST SP 800-171 ).

Access Control (AC) Domain Breakdown :

Level 1 : Contains 4 AC practices (e.g., limiting system access to authorized users).

Level 2 : Contains 22 AC practices total. This includes the original 4 from Level 1 and 18 additional practices (e.g., controlling the use of privileged functions, limiting unsuccessful logon attempts).

Level 3 (Expert) : This level adds even more practices from NIST SP 800-172 . While Level 3 " contains " Level 2, the question asks specifically about what the Advanced Level (Level 2) contains. Therefore, it contains Level 1 and Level 2 practices.

Why other options are incorrect :

Option A : Level 2 is not just Level 1; it includes the additional NIST 800-171 requirements.

Option B : Level 3 practices are part of the " Expert " level, not the " Advanced " level.

Option D : The " Advanced " level (Level 2) does not include the " Expert " (Level 3) practices.

Reference Documents :

CMMC Model Overview (v2.0/v2.1) : Section 3.2, " Level 2: Advanced, " which explicitly states the level consists of the 110 practices from NIST SP 800-171, which includes the Level 1 requirements.

32 CFR Part 170 (CMMC Program Rule) : Defines the mapping of the 14 domains and the cumulative nature of the certification levels.

CMMC Level 2 Assessment Guide : Lists all 22 Access Control practices required for a Level 2 assessment.

Control Reference: CA.L2-3.12.1

CA.L2-3.12.1: " Periodically assess the security controls in organizational systems to determine if the controls are effective in their application. "

This control is derived fromNIST SP 800-171, Requirement 3.12.1, which mandates organizations to performregular security control assessmentsto ensure compliance and effectiveness.

Assessment Criteria & Justification for the Correct Answer:

Evidence Review & Assessment Timeline:

The organization ' s procedureexplicitly statesthat security control assessments must be conductedquarterly(every three months).

Since the Lead Assessor only has access to thefirst-quarter report, the second-quarter report is missing at the time of assessment.

CMMC Audit Requirements:

For an assessor to rate a control asMET, sufficient evidence must bereadily availableat the time of evaluation.

Since the second-quarter report is missingat the time of assessment, the Lead Assessorcannot verify compliancewith the organization ' s own stated frequency of assessment.

Why the Answer is NOT A, C, or D:

A (Sufficient, MET)→Incorrect: The control assessment frequency is quarterly, but the evidence for Q2 is not available. Compliance cannot be confirmed.

C (Sufficient, and re-rate later)→Incorrect: If evidence is not available during the audit, the controlcannot be rated as MET initially. There is no provision in CMMC 2.0 to " conditionally " pass a control pending future evidence.

D (Insufficient, but re-rate later)→Incorrect: Once a control is ratedNOT MET, it staysNOT METuntil a re-assessment is conducted in a new audit cycle. The assessordoes not adjust ratings retroactivelybased on future evidence.

Official CMMC 2.0 References Supporting the Answer:

CMMC Assessment Process (CAP) Guide (2023):

" For a control to be rated as MET, the assessed organization must provide sufficient evidence at the time of the assessment. "

" If evidence is missing or incomplete, the finding shall be rated as NOT MET. "

NIST SP 800-171A (Security Requirement Assessment Guide):

" Evidence must be current, relevant, and sufficient to demonstrate compliance with stated periodicity requirements. "

Since the procedure mandatesquarterly assessments, missing evidence means compliancecannot be validated.

DoD CMMC Scoping Guidance:

" Assessors shall base their determination on the evidence provided at the time of assessment. If required evidence is not available, the control shall be rated as NOT MET. "

Final Conclusion:

Thecorrect answer is Bbecause the required evidence (the second-quarter report) is not availableat the time of assessment, making itinsufficientto validate compliance. The Lead Assessormust rate the control as NOT METin accordance with CMMC 2.0 assessment rules.

For SI.L2-3.14.7 (Identify Unauthorized Use) , the assessment objectives focus on two outcomes: (a) the organization has defined authorized use of the system, and (b) the organization identifies unauthorized use when it occurs. The strongest evidence is therefore evidence that the organization actively monitors systems and can detect and recognize activity outside the defined authorized-use baseline.

In the DoD CMMC Assessment Guide – Level 2 (v2.13) , the “Potential Assessment Methods and Objects” for SI.L2-3.14.7 emphasize artifacts that are directly tied to monitoring and detection—such as a continuous monitoring strategy , system and information integrity policy , procedures addressing system monitoring tools and techniques , and technical monitoring capabilities (e.g., tools/techniques like IDS/IPS , audit record monitoring , and network monitoring ).

These artifacts are exactly what demonstrate that unauthorized use is being identified in practice (alerts, logs, correlation, and review processes) and that authorized use is defined (policies/standards that establish what “authorized” looks like so “unauthorized” can be recognized).

By contrast, risk assessment/response and incident response may be related program elements, but they are not the primary evidence that the organization is continuously detecting unauthorized use. The assessment guide’s focus on monitoring artifacts makes System monitoring the best evidence.

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.
