Free Cyber AB CMMC-CCP Exam Dumps June 2026

In the context of the Cybersecurity Maturity Model Certification (CMMC) 2.0, particularly at Level 2, organizations are required to implement stringent controls to protect Controlled Unclassified Information (CUI). This includes adhering to specific practices related to media protection and physical security.

Media Protection (MP):

MP.L2-3.8.1 -- Media Protection:Organizations must protect (i.e., physically control and securely store) system media containing CUI, both paper and digital. This ensures that sensitive information is not accessible to unauthorized individuals.

Defense Innovation Unit

MP.L2-3.8.3 -- Media Disposal:It is imperative to sanitize or destroy information system media containing CUI before disposal or release for reuse. This practice prevents potential data breaches from discarded or repurposed media.

Defense Innovation Unit

Physical Protection (PE):

PE.L2-3.10.2 -- Monitor Facility:Organizations are required to protect and monitor the physical facility and support infrastructure for organizational systems. This includes ensuring that areas where CUI is processed or stored are secure and access is controlled.

Defense Innovation Unit

Application to the Scenario:

Given that the Organization Seeking Certification (OSC) operates within a shared, multi-tenant building and utilizes a common conference room for assessments, the following considerations are crucial:

Reviewing the Evidence File:The evidence file, which contains CUI, should be reviewed on a secure, authorized device to prevent unauthorized access or potential data leakage.

Printing the Evidence File:If printing is necessary, ensure that the printer is located in a secure area, and the printed documents are retrieved immediately to prevent unauthorized viewing.

Making Notes:Any notes derived from the evidence file should be treated with the same level of security as the original document, especially if they contain CUI.

Disposal of Printed Materials:After the assessment, all printed materials and notes containing CUI must be destroyed using a cross-cut shredder. Cross-cut shredding ensures that the information cannot be reconstructed, thereby maintaining confidentiality.

Options A and D are inadequate as they involve leaving sensitive information in unsecured locations, which violates CMMC physical security requirements. Option B, while secure in terms of digital handling, does not address the proper disposal of any physical copies that may have been made. Therefore, Option C is the best practice, aligning with CMMC 2.0 guidelines by ensuring that all physical media containing CUI are properly reviewed, securely stored during use, and thoroughly destroyed when no longer needed.

Understanding High-Level Scoping in a CMMC AssessmentDuringHigh-Level Scoping, aCertified Third-Party Assessment Organization (C3PAO)determines thepeople, processes, and technologythat are within scope for theCMMC Level 1 or Level 2 assessment.

Supporting Organization/Unitsrefer to thespecific groups, departments, or teamsthat handleControlled Unclassified Information (CUI)orFederal Contract Information (FCI)and are responsible for applyingCMMC security practices.

These units aredirectly involved in the contract's executionand are included in the CMMC assessment scope.

Key Term: Supporting Organization/Units

A . Host Unit Incorrect

This term is not used inCMMC assessment scoping.

B . Branch Office Incorrect

Abranch officemay or may not be in scope; scoping is based onwhether the unit handles CUI or FCI, not its physical location.

C . Coordinating Unit Incorrect

No official CMMC term refers to a 'Coordinating Unit.'

D . Supporting Organization/Units Correct

This termcorrectly describes the entities that apply security controls for the contract and are within the CMMC assessment scope.

Why is the Correct Answer 'D. Supporting Organization/Units'?

CMMC Assessment Process (CAP) Document

Specifies that theC3PAO must identify and document the units responsible for security compliance.

DoD CMMC 2.0 Guidance on Scoping

Requires theassessment team to define the people, processes, and technology that fall within the scopeof the assessment.

CMMC 2.0 Reference Supporting This Answer:

Understanding the Principle of Least Functionality in the CM DomainTheConfiguration 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.

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.

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.

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.

Justification for the Correct Answer: Least Functionality (C)Why Other Options Are

IncorrectOfficial CMMC and NIST ReferenceConclusionTheprinciple 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 is Responsible for Marking CUI?According toDoDI 5200.48 (Controlled Unclassified Information (CUI)), the responsibility for marking CUI falls on theauthorized holder of the information.

Definition of an Authorized Holder

PerDoDI 5200.48, Section 3.4, anauthorized holderis anyone who has beengranted accessto CUI and is responsible for handling, safeguarding, and marking it according toDoD CUI policy.

The authorized holder may be:

ADoD employee

Acontractorhandling CUI

Anyorganization or individual authorizedto access and manage CUI

DoD Guidance on CUI Marking Responsibilities

DoDI 5200.48, Section 4.2:

The individual creating or handling CUImust apply the appropriate markings as per the DoD CUI Registry guidelines.

DoDI 5200.48, Section 5.2:

Themarking responsibility is NOT limited to a specific positionlike an Information Disclosure Official or a high-level DoD office.

Instead, it is theresponsibility of the person or entity generating, handling, or disseminatingthe CUI.

Why the Other Answer Choices Are Incorrect:

(A) DoD OUSD (Office of the Under Secretary of Defense):

The OUSD plays apolicy-setting rolebut doesnot directly mark CUI.

(C) Information Disclosure Official:

This role is responsible forpublic release of information, but marking CUI is the duty of theauthorized holdermanaging the data.

(D) Presidential authorized Original Classification Authority (OCA):

OCAs classifynational security information (Confidential, Secret, Top Secret), not CUI, which isnot classified information.

Step-by-Step Breakdown:Final Validation from DoDI 5200.48:PerDoDI 5200.48, authorized holders are explicitly responsible for marking CUI, making this the correct answer.
