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

In the context of a Cybersecurity Maturity Model Certification (CMMC) assessment, the roles and responsibilities of individuals involved are clearly delineated to ensure a structured and effective evaluation process. The term "applicable staff" refers to personnel within the Organization Seeking Certification (OSC) who possess specific knowledge or expertise pertinent to the assessment. These individuals are integral to the assessment process as they provide essential information, demonstrate the implementation of security practices, and facilitate the assessment team's understanding of the organization's cybersecurity posture.

In this scenario, the employee serving as the primary system administrator is responsible for managing and maintaining the organization's systems. Given their comprehensive understanding of the system configurations, security controls, and operational procedures, this individual is best categorized as "applicable staff." Their involvement is crucial during the assessment, as they can provide detailed insights, demonstrate compliance measures, and address technical inquiries from the assessment team.

The other options can be delineated as follows:

Analyzer:Typically refers to individuals who analyze data or security incidents, often as part of a security operations center. This role is not specifically defined within the CMMC assessment context.

Inspector:Generally denotes a person who examines or inspects systems and processes, possibly as part of an internal audit or compliance check. This term is not a standard designation within the CMMC assessment framework.

Demonstration staff:While this could imply personnel responsible for demonstrating systems or processes, it is not a recognized role within the CMMC assessment process.

Therefore, the primary system administrator, by virtue of their role and responsibilities, aligns with the "applicable staff" category, playing a pivotal role in facilitating a successful CMMC assessment.

Contractors that handle Covered Defense Information (CDI) are required to report cyber incidents to the Department of Defense within 72 hours of discovery.

Supporting Extracts from Official Content:

DFARS 252.204-7012(c)(1): “When the Contractor discovers a cyber incident that affects a covered contractor information system or the covered defense information residing therein, the Contractor shall conduct a review… and rapidly report the cyber incident to DoD within 72 hours of discovery.”

Why Option C is Correct:

The regulation explicitly specifies 72 hours.

Options A (24 hrs), B (48 hrs), and D (96 hrs) do not align with DFARS requirements.

===========

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.

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.

Interview Selection in CMMC Assessments

During aCMMC assessment, theLead Assessormust work with theOrganization Seeking Certification (OSC)to select personnel for interviews. The goal is to:

✅Verify that personnel understand andperform security-related practices.

✅Ensure that individuals canexplain how they implement CMMC requirements.

✅Gain insight intoactual cybersecurity operationsrather than just documented policies.

The best interviewees are those whodirectly engage with security practicesand canclearly explain how they perform their duties.

Why "Providing Clarity and Understanding" Is Key

CMMC assessmentsrely on interviewsto validate that security practices areimplemented effectively.

Themost valuable intervieweesare those who canexplainhow security measures are appliedin day-to-day operations.

CMMC Assessment Process (CAP)emphasizes that assessors should speak tothose actively involved in security practicesrather than just senior management or policy owners.

Thus,option D is the correct choicebecause the Lead Assessor should prioritizeinterviewing personnel who can clearly explain how CMMC practices are implemented.

Why the Other Answers Are Incorrect

A. Have a security clearance.

❌Incorrect.Security clearance is not a requirementfor CMMC assessments. The focus is onpractical implementation of security controls, not classified work.

B. Be a senior person in the company.

❌Incorrect. Senior executives may not be involved in theactual implementation of security controls. The best interviewees are those whoperform the work, not just oversee it.

C. Demonstrate expertise on the CMMC requirements.

❌Incorrect. Whileunderstanding CMMC is important, expertise alonedoes not guarantee practical knowledgeof security controls. The key is thatinterviewees must provide clarity on how they perform security tasks.

CMMC Official References

CMMC Assessment Process (CAP) Document– Guides interview selection based on personnel who perform security functions.

NIST SP 800-171 & CMMC 2.0– Emphasize that cybersecurity controls must beactively implemented, not just documented.

Thus,option D (Provide clarity and understanding of their practice activities) is the correct answeras per official CMMC assessment guidelines.

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

✅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

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

Understanding the Principle of Least Functionality in the CM Domain

TheConfiguration Management (CM) domainin CMMC 2.0 focuses on maintaining the security and integrity of an organization’s systems through controlled configurations and restrictions on system capabilities.

The principle ofLeast Functionalityrefers to limiting a system’s features, services, and applications to only those necessary for its intended purpose. This principle reduces the attack surface by minimizing unnecessary components that could be exploited by attackers.

Justification for the Correct Answer: Least Functionality (C)

CMMC Practice CM.L2-3.4.6 (Use Least Functionality)explicitly states:

"Employ the principle of least functionality by configuring organizational systems to provide only essential capabilities."

Thegoalis to prevent unauthorized or unnecessary applications, services, and ports from running on the system.

Examples of Implementation:

Disabling unnecessary services, such as remote desktop access if not required.

Restricting software installation to approved applications.

Blocking unused network ports and protocols.

Why Other Options Are Incorrect

A. Least Privilege

This principle (associated with Access Control) ensures that users and processes have only the minimum level of access necessary to perform their jobs.

It is relevant to CMMC PracticeAC.L2-3.1.5 (Least Privilege)but does not define system capabilities.

B. Essential Concern

There is no officially recognized cybersecurity principle called "Essential Concern" in CMMC, NIST, or related frameworks.

D. Separation of Duties

This principle (covered under CMMCAC.L2-3.1.4) ensures that no single individual has unchecked control over critical functions, reducing the risk of fraud or abuse.

While important for security, it does not define essential system capabilities.

Official CMMC and NIST References

CMMC 2.0 Level 2 Assessment Guide – Configuration Management (CM) Domain

CM.L2-3.4.6 mandatesleast functionalityto enhance security by removing unnecessary features.

NIST SP 800-171 (which CMMC is based on) – Requirement 3.4.6

States:"Limit system functionality to only the essential capabilities required for organizational missions or business functions."

NIST SP 800-53 – Control CM-7 (Least Functionality)

Provides detailed recommendations on configuring systems to operate with only necessary features.

Conclusion

Theprinciple of Least Functionality (C)is the basis for defining essential system capabilities in theConfiguration Management (CM) domainof CMMC 2.0. By applying this principle, organizations reduce security risks by ensuring that only the necessary functions, services, and applications are enabled.

Who Do DoD Contractors Report CUI Breaches To?

CMMC v2.0 scoping defines “in-scope” assets for Level 1 (FCI protection) based on whether the asset processes, stores, or transmits FCI . The DoD CMMC Assessment Scope – Level 1 (v2.13) states: “Assets in scope … are all assets that **process, store, or transmit Federal Contract Information (FCI).” It then defines these terms. Critically for this question, Store is defined as when “FCI is inactive or at rest on an asset (e.g., located on electronic media…).”

A flash drive is “electronic media.” If the program manager places contract-relevant FCI onto the flash drive, the flash drive is now an asset that stores FCI (FCI at rest). Under the scoping guidance, that alone is enough to classify it as an in-scope FCI asset for Level 1 purposes, meaning it falls within the Level 1 assessment scope and must be protected by applicable Level 1 requirements.

The other answer choices do not align to the scoping definitions. “Testing FCI” (B) is not one of the scope-determining criteria in the Level 1 scoping guide. “Distributing FCI” (C) is not the formal criterion either (the guide uses Transmit , not “distribute”). Finally, being “properly marked” (D) does not determine whether something is in scope; the decisive factor is whether the asset processes, stores, or transmits FCI.
