Cyber AB CMMC-CCP - Certified CMMC Professional (CCP) Exam

Step 1: Understand the “CA” Domain – Security Assessment

TheCA (Security Assessment)domain includes practices related to:

Planning security assessments,

Performing periodic reviews,

Managing plans of action and milestones (POA & Ms).

These practices derive fromNIST SP 800-171, specifically:

CA.2.157– Develop, document, and periodically update security plans,

CA.2.158– Periodically assess security controls,

CA.2.159– Develop and implement POA & Ms.

✅Step 2: Review CMMC Levels

Level 1 (Foundational):

Implements only the17 practicesfromFAR 52.204-21

Doesnot include the CA domain

Level 2 (Advanced):

Implements110 practicesfromNIST SP 800-171, including CA.2.157–159

First levelwhereSecurity Assessment (CA)practices are required

Level 3:

Not yet finalized but intended to include selected controls fromNIST SP 800-172

❌Why the Other Options Are Incorrect

A. Level 1

✘No CA domain practices are present at Level 1.

C. Level 3 / D. Level 4

✘These levels build on CA practices but do not represent thestarting point.

TheSecurity Assessment (CA)domain practices begin atCMMC Level 2, as part of the implementation ofNIST SP 800-171.

Scoping Requirements in CMMC Assessments

TheCMMC 2.0 Scoping GuideandCMMC Assessment Process (CAP) Documentclearly define what should be included in the scope of an assessment.

The assessment scope must cover:

All assets that process, store, or transmit FCI/CUI

Security Protection Assets (ESP)– these assets help protect FCI/CUI, such as firewalls, endpoint detection systems, and encryption mechanisms.

Thus, thecorrect scope includes both:

✅FCI/CUI Assets(Data storage, processing, or transmission assets)

✅Security Protection Assets (ESP)(Firewalls, security tools, etc.)

Why the Other Answers Are Incorrect

A. All assets documented in the business plan

❌Incorrect.Business plans may include assets unrelated to FCI/CUI, making this scopetoo broad. Only assets relevant to FCI/CUI should be assessed.

B. All assets regardless if they do or do not process, store, or transmit FCI/CUI

❌Incorrect. CMMC doesnotrequire organizations to include assets thathave no connection to FCI/CUI.

C. All entities, regardless of the line of business, associated with the organization

❌Incorrect.Only the assets relevant to FCI/CUI or security protection should be assessed. Unrelated business divisions (like a non-federal commercial division) areout-of-scope.

CMMC Assessment Process (CAP) Document

Thus,option D (All assets processing, storing, or transmitting FCI/CUI and security protection assets) is the correct answeras per official CMMC assessment scoping requirements.

Planning and preparing for aCMMC assessmentinvolves collaboration between theassessorand theOrganization Seeking Certification (OSC)to determine scope, required evidence, and logistics. This planning process isdynamicand must adapt as new information emerges.

Why the Correct Answer is "D"?

Assessment Scope and Requirements May Change

As assessors gather evidence and analyze the environment,new details about assets, networks, and security controlsmay require adjustments to the assessment plan.

TheCMMC Assessment Process (CAP) Guideemphasizes that assessmentrequirements and scope should be continuously reviewed and updatedto reflect real-time findings.

Assessors Follow an Adaptive Approach

DuringCMMC assessments, organizations may discover additionalFCI or CUI assets, which can change the required security practices to be evaluated.

Assessors shouldrevise the assessment approach accordinglyrather than strictly following an initial, unchangeable plan.

Why Not the Other Options?

A. Scoping an assessment is easy and worry-free→Incorrect

Scoping is acritical and complex processthat requires careful evaluation of the OSC’s information systems and assets.

CMMC Scoping Guidestates thatidentifying in-scope assets is crucial and requires significant effort.

B. The initial plan cannot be changed once agreed upon→Incorrect

Theinitial assessment plan is a starting point, butit must be flexiblebased on real-time findings.

CMMC CAP Guideemphasizescontinuous refinementduring the assessment process.

C. There is a determined amount of time that the OSC's point of contact has to submit evidence and rough order-of-magnitude→Incorrect

While there aretimelines, the key focus is ensuring thatall necessary evidence is gathered accuratelyrather than rushing to meet a strict deadline.

Relevant CMMC 2.0 References:

CMMC Assessment Process (CAP) Guide– States that assessment requirements and planning should be updated as additional information is gathered.

CMMC Scoping Guide (Nov 2021)– Explains that assessors must continually refinein-scope assets and requirementsthroughout the process.

Final Justification:

Assessment planning is a dynamic process.Assessors must continuously review and update the requirements and planas new information emerges, makingDthe correct answer.

Understanding IA.L1-3.5.1 (Identification and Authentication Requirements)

TheCMMC 2.0 Level 1practiceIA.L1-3.5.1aligns withNIST SP 800-171, Requirement 3.5.1, which mandates that organizationsidentify system users, processes acting on behalf of users, and devicesto ensure proper access control.

To comply with this requirement, anOrganization Seeking Certification (OSC)must maintain documentation that demonstrates:

A unique identifier (username) for each system user

Mapping of system accounts to specific individuals

Identification of devices and automated processes that access systems

Why "C. User names associated with system accounts assigned to those individuals" is Correct?

This documentation directly satisfies IA.L1-3.5.1because it showshow system users are uniquely identified and linked to specific accountswithin the environment.

Alist of users and their assigned accountsconfirms that the organization has a structured method oftracking access and authentication.

It allows auditors to verify thateach user has a distinct identityand that access control mechanisms are properly applied.

Why Other Answers Are Incorrect?

A. Procedures for implementing access control lists (Incorrect)

While access control lists (ACLs) are relevant for authorization, they do notidentify users or devicesspecifically, making them insufficient as primary evidence for IA.L1-3.5.1.

B. List of unauthorized users that identifies their identities and roles (Incorrect)

Identifying unauthorized users does not fulfill the requirement of trackingauthorizedusers, devices, and processes.

D. Physical access policy stating "All non-employees must wear a special visitor pass or be escorted" (Incorrect)

This pertains tophysical security, not system-baseduser identification and authentication.

Conclusion

The correct answer isC. User names associated with system accounts assigned to those individuals, as thisdirectly satisfies the identification requirement of IA.L1-3.5.1.

Under the Cybersecurity Maturity Model Certification (CMMC) 2.0, a Plan of Action (POA) is a critical document that outlines the specific actions a contractor needs to take to remediate cybersecurity deficiencies. While POAs serve as a roadmap for achieving compliance with required controls, the inclusion of certain elements is standardized.

Key Elements of a Plan of Action (POA)

According to the CMMC guidelines and NIST SP 800-171, which underpins many CMMC requirements, a POA typically includes:

Completion Dates: Identifies target deadlines for resolving deficiencies.

Milestones to Measure Progress: Includes interim steps or markers to ensure progress is monitored over time.

Ownership or Accountability: Clearly assigns responsibility for each action item to specific personnel or teams.

What is Generally NOT Part of a POA?

Budget requirements to implement the plan's remediation actions (Option D) are generally not included in a POA. While budgeting is critical for ensuring the plan's success, it is considered a part of the broaderproject management or resource planning process, not the POA itself. This distinction is intentional to keep the POA focused on actionable items rather than resource allocation.

Supporting Reference

NIST SP 800-171A, Appendix D: Provides an overview of POA components, emphasizing the prioritization of corrective actions, responsibility, and measurable outcomes.

CMMC Level 2 Practices (Aligned with NIST SP 800-171): Specifically, the focus is on actions, timelines, and accountability rather than financial planning.

By excluding budget details, the POA remains a tactical document that supports immediate action and compliance tracking, separate from financial considerations.

CMMC Assessment Process (CAP) and CMMC Code of Professional Conduct emphasize that conflicts of interest (COI) must be disclosed and managed transparently. A Certified CMMC Professional (CCP) is required to:

Inform their organization,

Disclose the COI to the affected stakeholders, and

Take reasonable steps to minimize the impact.

What they must NOT do is conceal it from the Assessment Team Lead or others. Concealing a COI violates the CMMC Code of Professional Conduct and compromises the integrity of the assessment.

Reference Documents:

CMMC Assessment Process (CAP), v1.0

CMMC Code of Professional Conduct, CMMC-AB

Under NIST SP 800-171, Personnel Security (PS) family, requirement PS.L2-3.9.1, organizations must screen individuals prior to granting access to CUI. The screening is intended to evaluate conduct, integrity, and loyalty to ensure that individuals can be trusted with sensitive information.

Supporting Extracts from Official Content:

NIST SP 800-171 Rev. 2, PS.L2-3.9.1: “Screen individuals prior to authorizing access to organizational systems containing CUI… Screening is intended to assess an individual’s conduct, integrity, judgment, loyalty, and reliability.”

CMMC Level 2 Assessment Guide (Personnel Security practices): confirms that screening covers conduct, integrity, and loyalty.

Why Option C is Correct:

The key attributes explicitly listed are conduct, integrity, and loyalty.

Options A and B describe subjective or informal measures, not compliance criteria.

Option D uses terms not aligned with the official requirement.

What Happens in Phase 4 of the CMMC Assessment Process?

Phase 4 of theCMMC Assessment Process (CAP)is theFinal Reporting and Decision Phase. During this phase, theLead Assessormust:

Review all assessment findings

Determine the Organization Seeking Certification’s (OSC) eligibility for certification

Make a recommendation to the C3PAO (Certified Third-Party Assessment Organization)

Key Responsibilities of the Lead Assessor in Phase 4:

Ensure that the OSC hasmet the required practices and processes.

Confirm that anydeficiencieshave been corrected or appropriately documented.

Recommendwhether the OSC is eligible for certificationbased on assessment results.

Since theLead Assessor must determine and recommend the OSC’s eligibilityto the C3PAO, the correct answer isB. Eligibility.

Why the Other Answers Are Incorrect

A. Ability

❌Incorrect. While assessing an OSC’s ability to meet CMMC requirements is part of the process, the final determination in Phase 4 is abouteligibilityfor certification.

C. Capability

❌Incorrect. Capability refers to an organization'stechnical and operational readiness. The Lead Assessor is making a recommendation oneligibility, not just capability.

D. Suitability

❌Incorrect. Suitability is not a defined term in theCMMC CAP processfor final assessment recommendations. The correct term iseligibility.

CMMC Official References

CMMC Assessment Process (CAP) Document– Specifies that the Lead Assessor must determine and recommend theeligibilityof the OSC in Phase 4.

CMMC 2.0 Model– Defines the assessment process, including certification decision-making.

Thus,option B (Eligibility) is the correct answer, as per official CMMC guidance.

This question aligns to the CMMC requirement to control information posted or processed on publicly accessible information systems , which appears in the CMMC Model Overview as AC.L1-3.1.22 (Control Public Information) and maps to FAR 52.204-21(b)(1)(iv) and NIST SP 800-171 Rev. 2 / r2 requirement 3.1.22 .

NIST explains that publicly accessible systems are typically those accessible to the public without identification or authentication , and that individuals authorized to post nonpublic information (including CUI/FCI and proprietary information) are designated . It also emphasizes controlling what gets posted and ensuring nonpublic information is not exposed.

The most direct technical way to “limit individuals who are authorized to post or process information” is to implement role-based administrative access (least privilege) to the website/CMS/admin console—granting publish/edit privileges only to approved roles (e.g., “Web Publisher,” “Content Approver”), and keeping all other users read-only or without access to posting functions. This directly enforces the requirement by using access control to restrict who can post/process content on the public system.

Options B and C are helpful procedural/administrative controls , but the question asks for technical means . Option A (cookies) does not control authorization to post; it’s not an access control mechanism. Therefore, D is best.

In the context of the Cybersecurity Maturity Model Certification (CMMC) Assessment Process, understanding the roles of various entities associated with an Organization Seeking Certification (OSC) is crucial during the planning phase. When a Certified Third-Party Assessment Organization (C3PAO) staff reviews these entities for a CMMC Level 2 Assessment, it's essential to distinguish between internal components and external participants.

Step-by-Step Explanation:

Definition of the HQ Organization:

The HQ Organization refers to the entire legal entity delivering services under the terms of a Department of Defense (DoD) contract. This entity is responsible for ensuring compliance with CMMC requirements.

Identification of External Entities:

External entities encompass people, processes, and technology that are not part of the HQ Organization but support its operations. These entities participate in the assessment process due to their involvement in handling Controlled Unclassified Information (CUI) or Federal Contract Information (FCI) related to the DoD contract.

Role of Supporting Organizations/Units:

According to the CMMC Assessment Process documentation, Supporting Organizations are defined as "the people, procedures, and technology external to the HQ Organization that support the Host Unit." These external entities are integral to the operations of the Host Unit but are not encompassed within the HQ Organization's immediate structure.

Assessment Implications:

While Supporting Organizations/Units play a vital role in supporting the Host Unit, they do not receive a separate CMMC Level certification unless an enterprise assessment is conducted. In such cases, the assessment would encompass both the HQ Organization and its Supporting Organizations to ensure comprehensive compliance across all associated entities.
