CMMC-CCP Exam Dumps - Cyber AB CMMC Questions and Answers

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.

C3PAO Authorization Requirements: Outlines the requirement for a quality management review of all assessment findings by the C3PAO before submission to the DoD.

DoDI 5200.48 specifies that Authorized Holders of CUI are responsible for applying appropriate CUI markings. An authorized holder is an individual who has lawful government purpose access to the information. This ensures that responsibility for correctly marking information rests with those who create or handle the material, not only with original classification authorities (which apply to classified information, not CUI).

Step 1: Understanding CMMC Level 1 Self-Assessment Scope

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.

Step 2: Why the Thermostat is in Scope

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.

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.

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.

Step 1: Understand the Assessment Phases (CAP v1.0)

TheCMMC Assessment Process (CAP)outlines a structured lifecycle for assessments, including:

Plan and Prepare Phase– Develop the assessment plan (before the assessment starts).

Conduct Assessment Phase– Execute the actual assessment activities.

Report Results Phase– Finalize and deliver the assessment outcomes.

CAP v1.0 – Section 3.5 (Conduct Assessment):

“The assessment team collects, examines, and evaluates evidence to determine if practices are MET or NOT MET.”

✅Step 2: Why “Collect and Examine Evidence” Is the Primary Activity

During the“Conduct Assessment” phase, the main activity is to:

Collect evidence(documentation, interviews, testing),

Validate adequacy and sufficiency,

Score practicesas MET/NOT MET.

This is thecore responsibilityof assessorswhile conductingan assessment.

❌Why the Other Options Are Incorrect

A. Develop assessment plan

✘This occurs in thePlan and Preparephasebeforeconducting the assessment.

C. Verify readiness to conduct assessment

✘Readiness verification is part ofpre-assessment activities, not during the assessment itself.

D. Deliver recommended assessment results

✘This is done during theReport Resultsphase after the assessment has been conducted.

Theprimary activity performed during the actual executionof a CMMC assessment iscollecting and examining evidenceto determine compliance with practices.

The correct answer is A because the first ethical response to observing a possible Code of Professional Conduct violation is proportionate, professional, and corrective—not punitive or investigative. A CMMC professional must preserve objectivity, professionalism, and accountability while avoiding escalation beyond the facts. Privately requesting clarification allows the professional to confirm whether the observed behavior is truly a violation rather than a misunderstanding. Offering to help rectify the violation supports remediation while maintaining professional respect and confidentiality. Option B is too aggressive because the DoD contract representative is not the first point for routine ecosystem conduct correction. Option C is inappropriate because a CMMC professional does not have authority to conduct a private investigation into another ecosystem member. Option D is also premature because a corrective action review to the CMMC-AB would normally follow unresolved, material, or reportable misconduct, not a first observation that may be clarified or corrected. The ethical principle is disciplined escalation: address the matter directly and professionally first, preserve evidence if needed, and escalate only if the conduct is confirmed, material, or unresolved. Reference/topics: CMMC-AB Code of Professional Conduct, professionalism, objectivity, accountability, ethical escalation.

The correct answer is B because FedRAMP is a federal authorization program for cloud services, not a self-assessment framework for ordinary IT contractors and not a program for on-premise products. In the CMMC context, FedRAMP becomes especially important when a contractor uses an external cloud service provider to store, process, or transmit covered defense information or CUI. DFARS 252.204-7012 requires the contractor to ensure that the cloud service provider meets security requirements equivalent to the FedRAMP Moderate baseline when covered defense information is handled in an external cloud service. FedRAMP itself also maintains a marketplace of certified cloud services, authorizing agencies, and recognized assessors. Therefore, the target participants are cloud service providers offering cloud products and services that need federal authorization or recognition. Options A and C incorrectly frame FedRAMP as a contractor self-assessment model. Option D is wrong because FedRAMP is focused on cloud service offerings, not traditional on-premise products or services. Reference/topics: FedRAMP, cloud service providers, DFARS 252.204-7012, external cloud services, FedRAMP Moderate baseline.

According to the CMMC Scoping Guidance, Level 1, the fundamental definition of an FCI Asset is any asset that performs at least one of three primary functions with Federal Contract Information (FCI). These functions are consistently defined across both Level 1 and Level 2 documentation as Processing, Storing, or Transmitting.

Process: In this scenario, the sales representative is " entering FCI data into various fields. " The act of inputting, manipulating, or editing data within an application (the spreadsheet) is the definition of processing.

Store: Because the spreadsheet is on the laptop, the data resides on the laptop ' s hard drive or memory. This constitutes storing.

Transmit: While the prompt focuses on the data entry, a laptop is an endpoint designed to move data across a network (email, cloud uploads, or server saves). In the context of CMMC scoping, assets that handle protected information are categorized by their capability and role in the data lifecycle, which includes transmitting.

Why other options are incorrect:

Options B and D: These include the word " organize. " While organizing data is a task a human performs, it is not a formal technical term used in the CMMC or NIST SP 800-171/FAR 52.204-21 definitions to categorize asset functions.

Option A: This option omits " store. " Since the spreadsheet exists on the laptop, storage is a primary function being utilized.

Reference Documents:

CMMC Scoping Guidance, Level 1 (Version 2.0): Section 2.0, which defines FCI Assets as assets that " process, store, or transmit FCI. "

FAR 52.204-21 (Basic Safeguarding of Covered Contractor Information Systems): The regulatory source for Level 1, which applies to systems that " process, store, or transmit " federal contract information.

CMMC Assessment Guide, Level 1: Introduction and Scoping sections, reinforcing the triad of data handling functions.

CAP v2.0 makes “assessment readiness” a formal gate in Phase 1 (Conduct the Pre-Assessment) . The purpose of Phase 1 is for the C3PAO to evaluate whether the OSC has adequately prepared for the assessment of its Level 2 security requirements. If evidence submitted ahead of the assessment is found to be insufficient such that the OSC is not prepared to proceed, CAP describes an Adverse Determination of Assessment Readiness : the Lead CCA should inform the Affirming Official and provide a written explanation for recommending the assessment be suspended —without giving remedial advice.

CAP then addresses what happens next: if the OSC decides to cancel or postpone the assessment, both parties should settle affairs per the agreement (including return of proprietary information), and they may discuss revisiting the assessment when the OSC is fully prepared. This maps directly to “Postpone the assessment” as the best answer.

The other options don’t match CAP’s prescribed handling. CAP does not require notifying the Cyber AB for routine evidence insufficiency (A). “Cancel” (B) is an OSC decision path, but CAP explicitly calls out postponement/suspension as the appropriate procedural response to lack of readiness. “Contact the C3PAO for guidance” (D) is unnecessary framing here because the assessor/Lead CCA is acting on behalf of the C3PAO under CAP’s Phase 1 readiness determination and suspension process.

NIST SP 800-88 Rev. 1 is the authoritative guide for media sanitization. It defines three categories of data disposal: Clear, Purge, and Destroy.

Supporting Extracts from Official Content:

NIST SP 800-88 Rev. 1: “Media sanitization techniques are divided into three categories: Clear, Purge, and Destroy.”

Why Option A is Correct:

“Clear, Purge, Destroy” are the exact three categories named.

Redact and Overwrite are not categories; Overwriting is a technique that may fall under Clear.
