Free Practice Questions for Cyber AB CMMC-CCP Exam

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.

Understanding CMMC Assessment Procedures

ACMMC assessment procedureconsists of:

Assessment Objective– Defines what is being evaluated and the expected outcome.

Assessment Methods– Specifies how the evaluation is conducted (e.g.,examination, interviews, testing).

Assessment Objects– Identifies what is being evaluated, such as policies, systems, or people.

Why the Correct Answer is "C"?

Assessment Objectivesincludedetermination statementsthat describe the expected outcome for each CMMC security practice.

These statements define whether a practice has beenadequately implementedbased ondocumented evidence and assessment findings.

TheCMMC Assessment Process (CAP) GuideandNIST SP 800-171Aspecify that each practice has a determination statement guiding assessment decisions.

Why Not the Other Options?

A. Specifications and mechanisms→Incorrect

These belong toassessment objects, which refer to the systems, policies, and mechanisms being evaluated.

B. Examination, interviews, and testing→Incorrect

These areassessment methods, which describe how assessorsverifycompliance (e.g., through interviews or testing).

D. Exercising assessment objects under specified conditions→Incorrect

This refers toassessment testing, which is a method, not an assessment objective.

Relevant CMMC 2.0 References:

CMMC Assessment Process (CAP) Guide– Describes determination statements as the core of assessment objectives.

NIST SP 800-171A– Defines determination statements as a key element of evaluating security controls.

Final Justification:

Since anassessment objectiveincludes adetermination statementthat describes whether a practice is implemented properly, the correct answer isC.

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.

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.

When preparing forCMMC compliance, organizations must ensure that theirnetwork configurations align with required cybersecurity controls. Ifnetwork administratorsdisagree on certain configurations, the mostobjective and accurateway to resolve the disagreement is by referencingofficial CMMC guidanceandNIST SP 800-171 requirements, which form the foundation of CMMC Level 2.

Step-by-Step Breakdown:

CMMC Assessment Guides as the Primary Reference

TheCMMC Assessment Guides (Level 1 & Level 2)provide clearinterpretationsof security practices.

Theyexplain how each practice should be implemented and assessedduring certification.

NIST SP 800-171 as the Compliance Baseline

CMMC Level 2is based directly onNIST SP 800-171, which outlines the110 security controlsrequired for protectingControlled Unclassified Information (CUI).

Network configurations must complywith NIST-defined security requirements, including:

Access Control (AC) – Ensuring least privilege principles.

Audit and Accountability (AU) – Logging and monitoring network activity.

System and Communications Protection (SC) – Secure network design and encryption.

Why the Other Answer Choices Are Incorrect:

(A) Consult with the CEO of the company:

ACEO is not necessarily a cybersecurity expertand may not be familiar with CMMC technical requirements.

Technical compliance decisions should be based onCMMC and NISTframeworks, not executive opinions.

(C) Go with the network administrator's ideas with the least stringent controls:

Choosingless stringent controls increases security riskand could lead toCMMC non-compliance.

(D) Go with the network administrator's ideas with the most stringent controls:

While security is important,more stringent controlsmay introduceoperational inefficienciesorunnecessary coststhat are not required for compliance.

The correct approach is to implement what is required by CMMC and NIST SP 800-171, no more and no less.

Final Validation from CMMC Documentation:

TheCMMC Assessment GuidesandNIST SP 800-171 Rev. 2areofficial sourcesthat provide the most reliable guidance on compliance.

CMMC Level 2 is entirely based on NIST SP 800-171, making it the definitive source for resolving security disagreements.

Thus, the correct answer is:

B. Consult the CMMC Assessment Guides and NIST SP 800-171.

Understanding Configuration Management (CM) in CMMC Level 2

InCMMC Level 2, theConfiguration Management (CM) domainis critical for ensuring that systems aresecurely configured, maintained, and monitoredto prevent unauthorized changes. One key aspect of CM is managinguser-installed software, which can introducesecurity risksif not properly controlled.

The correct approach to managinguser-installed softwarealigns withCM.3.068fromNIST SP 800-171, which requires organizations to:

✅Establish and enforce configuration settingsto ensure security.

✅Monitor and control user-installed softwareto prevent unauthorized or insecure applications from running on organizational systems.

Why "Controlled and Monitored" is Correct?

The CCP (Certified CMMC Professional) conducting theinterviewshould focus on whether theuser-installed softwareiscontrolled and monitoredto align withCMMC Level 2 requirements. This means verifying:

Approval processesfor user-installed software.

Monitoring mechanisms(e.g., system logs, audits) to track software changes.

Policies that restrict unauthorized installationsto prevent security risks.

Breakdown of Answer Choices

Option

Description

Correct?

A. Controlled and monitored

✅Ensures compliance with CM.3.068, verifying that user-installed software ismanaged securely.

✅Correct

B. Removed from the system

Software isnot always removed—only unauthorized or risky software should be.

❌Incorrect

C. Scanned for malicious code

While scanning isimportant(covered in SI.3.218), it isnot the primary focusof Configuration Management.

❌Incorrect

D. Limited to mission-essential use only

While limiting software is useful,monitoring and controllingis the key security measure.

❌Incorrect

Official Reference from CMMC 2.0 Documentation

NIST SP 800-171, CM.3.068– "Control and monitor user-installed software."

CMMC 2.0 Level 2 Requirements– Directly aligned withNIST SP 800-171 security controls.

Final Verification and Conclusion

The correct answer isA. Controlled and monitored, as perCM.3.068inNIST SP 800-171andCMMC 2.0documentation.

Per the CMMC Assessment Process (CAP), when planning an assessment, the Lead Assessor must coordinate with the Organization Seeking Certification (OSC) to select interview participants who can provide clarity and understanding of their practice activities. The intent is to interview individuals directly involved with and knowledgeable about the processes and practices under review, rather than selecting personnel based solely on rank, clearance, or formal expertise in CMMC.

This ensures the assessment is evidence-based and grounded in how practices are actually performed within the OSC.

Reference Documents:

CMMC Assessment Process (CAP), v1.0

A Restricted Information System (IS) is defined as an asset that cannot meet modern security controls but is still needed for contract performance. These systems may be declared out of scope if they are properly isolated, mitigated, and documented. A legacy Windows 95 computer meets the definition of a restricted IS.

Supporting Extracts from Official Content:

CMMC Scoping Guide (Level 2): “Restricted IS assets are those that cannot reasonably apply security requirements due to legacy or operational constraints. They are not assessed but must be identified and protected by alternative methods.”

Why Option B is Correct:

The Windows 95 system is an example of a restricted IS, so it can be scoped out.

Option A is incorrect — the asset is not handling CUI in this case.

Option C is incorrect — government property designation does not define scope.

Option D is incorrect — while it is “legacy,” it is not classified as OT; the correct CMMC term is restricted IS.

===========

1. Understanding Basic Safeguarding Requirements for FCI in CMMC Level 1

Federal Contract Information (FCI) is defined as information provided by or generated for the government under a contract that isnot intended for public release.

CMMCLevel 1is designed to ensurebasic safeguardingof FCI, aligning with15 security requirementsfound inFAR 52.204-21 (Basic Safeguarding of Covered Contractor Information Systems).

Contractors handlingonly FCImust meetCMMC Level 1, which alignsdirectlywith the safeguarding requirements set inFAR 52.204-21.

2. FAR 52.204-21 and Its Role in CMMC Level 1 Compliance

FAR 52.204-21establishes the baseline cybersecurity controls that contractors must implement to protectFCI.

The15 basic safeguarding requirementsinclude:

Limiting information accessto authorized users.

Identifying and authenticating usersbefore allowing system access.

Protecting transmitted FCIfrom unauthorized disclosure.

Monitoring and controlling connectionsto external systems.

Applying boundary protectionand cybersecurity measures.

Sanitizing mediabefore disposal.

Updating security configurationsto reduce vulnerabilities.

Providing physical securityprotections.

Controlling physical accessto systems that process FCI.

Enforcing multi-factor authentication (MFA) where applicable.

Patching vulnerabilitiesin software and hardware.

Limiting the use of removable media.

Creating and retaining system audit logs.

Performing risk-based security assessments.

Developing an incident response plan.

These 15 practices form thefoundationof CMMCLevel 1 Self-Assessment, ensuring contractorsmeet minimum cybersecurity expectationsfor handling FCI.

3. Why the Other Options Are Incorrect

B. 22 CFR 120-130:

This refers toInternational Traffic in Arms Regulations (ITAR), which controls the export of defense-related articles and services,notFCI safeguarding requirements.

C. DFARS 252.204-7011:

This clause refers toalternative line item structuresand does not pertain to cybersecurity or safeguarding FCI.

D. DFARS 252.204-7021:

This clause enforcesCMMC requirementsbut doesnot definebasic safeguarding controls. It requires compliance with CMMC but does not specify the foundational requirements (which come fromFAR 52.204-21for Level 1).

4. Official CMMC 2.0 Reference & Study Guide Alignment

TheCMMC 2.0 model documentationconfirms that Level 1 is focused on the15 practices from FAR 52.204-21.

TheDoD’s official CMMC Assessment Guidefor Level 1 explicitly states that meeting FAR 52.204-21 is therequirement for passing a Level 1 Self-Assessment.

TheCMMC 2.0 Scoping Guideclarifies that contractors handling onlyFCIand seekingLevel 1 certificationmust implementonly FAR 52.204-21security controls.

Final Confirmation:

The correct answer isA. FAR 52.204-21, as it directly governs the basic safeguarding ofFCIand is the foundational requirement for aLevel 1 Self-Assessmentin CMMC 2.0.

Step 1: Define CUI (Controlled Unclassified Information)

CUI is information thatrequires safeguarding or dissemination controlspursuant to and consistent with applicable law, regulations, and government-wide policies, butis not classifiedunder Executive Order 13526 or the Atomic Energy Act.

✅Step 2: Authority over CUI — NARA’s Role

NARA – National Archives and Records Administration, specifically theInformation Security Oversight Office (ISOO), is thegovernment-wide executive agentresponsible for implementing the CUI program.

Source:

32 CFR Part 2002 – Controlled Unclassified Information (CUI)

Executive Order 13556 – Controlled Unclassified Information

CUI Registry – https://www.archives.gov/cui

NARA:

Maintains theCUI Registry,

Issuesmarking and handling guidance,

DefinesCUI categoriesand their authority under law or regulation,

Trains and informs Federal agencies and contractors on CUI policy.

❌Why the Other Options Are Incorrect

B. NIST

✘NIST (National Institute of Standards and Technology) developstechnical standards(e.g., SP 800-171), but it doesnot define or mark CUI. It helps secure CUI once it’s identified.

C. CMMC-AB (now Cyber AB)

✘The Cyber AB is theCMMC ecosystem’s accreditation body, not a government agency, and hasno authority over CUI classification or marking.

D. Department of Homeland Security (DHS)

✘While DHS mayhandle and protect CUI internally, it is not the executive agent for the CUI program.

NARAis theofficial U.S. government authorityresponsible for defining, categorizing, and marking CUI via theCUI Registryand associated policies underExecutive Order 13556.
