Understanding Scoping in CMMC 2.0

TheCMMC 2.0 framework applies to nonfederal systemsthat process, store, or transmitCUI.

Scoping determineswhich system components must comply with CMMC practices.

If a systemprocesses, stores, or transmits CUI, orprovides security for those systems, itmust be included in the assessment scope.

Why the Correct Answer is " D. Nonfederal systems that process, store, or transmit CUI, or that provide protection for the system components " ?

CMMC Applies to Contractors, Not Federal Systems

CMMC isdesigned for Department of Defense (DoD) contractors, notfederal systems.

Federal systems arealready governed by NIST SP 800-53and other regulations.

Scope Includes Systems That Process CUI AND Those That Protect Them

Systemsprocessing, storing, or transmitting CUIare in scope.

Systems thatprovide protection for CUI systems(e.g., firewalls, monitoring tools, security appliances) arealso in scope.

Why Not the Other Options?

A. Federal systems that process, store, or transmit CUI.→Incorrect

CMMCdoes not apply to federal systems.

B. Nonfederal systems that process, store, or transmit CUI.→Partially correct but incomplete

Itexcludes security systemsthat protect CUI assets, whichare also in scope.

C. Federal systems that process, store, or transmit CUI, or that provide protection for the system components.→Incorrect

CMMConly applies to nonfederal systems.

Relevant CMMC 2.0 References:

CMMC Scoping Guide (Nov 2021)– Confirms that CMMCapplies to nonfederal systemsprocessingCUI.

NIST SP 800-171 Rev. 2– Specifies security requirements fornonfederal systemshandling CUI.

DFARS 252.204-7012– Requires DoD contractors to implementNIST SP 800-171onnonfederal systemshandling CUI.

Final Justification:

SinceCMMC applies to nonfederal systems that process CUI or protect those systems, the correct answer isD. Nonfederal systems that process, store, or transmit CUI, or that provide protection for the system components.

The correct answer is C because DFARS 252.204-7012 is explicitly titled “Safeguarding Covered Defense Information and Cyber Incident Reporting.” This clause is one of the core governance and source-document foundations for CMMC because it establishes contractor obligations for protecting covered defense information, including CUI/CDI, on covered contractor information systems. It defines covered contractor information systems as unclassified systems owned or operated by or for a contractor that process, store, or transmit covered defense information. It also requires contractors to provide adequate security and implement NIST SP 800-171 security requirements where applicable. In addition, it requires contractors to rapidly report cyber incidents affecting covered contractor systems or covered defense information, with “rapidly report” defined as within 72 hours of discovery. Options A, B, and D are not the clause titled for safeguarding CDI and cyber incident reporting. DFARS 252.204-7020 relates to NIST SP 800-171 DoD assessment requirements, while DFARS 252.204-7021 addresses CMMC requirements. Reference/topics: DFARS 252.204-7012, CDI/CUI safeguarding, cyber incident reporting, CMMC source documents.

In the CAP v2.0 “preliminary proceedings,” the assessment is “framed” before Phase 1/Phase 2 execution. CAP states the C3PAO works with the OSC’s leadership point(s) of contact (the Affirming Official and/or OSC POC ) “to determine the purview and planning details of the assessment,” explicitly including schedule , personnel , logistics , relevant contractual requirements, and the prospective CMMC Assessment Scope .

Although the question uses the term “OSC sponsor,” the CAP’s official role language is Affirming Official / OSC POC , and the Lead CCA (Lead Assessor) is the assessor counterpart. CAP further explains that the In-Brief Meeting establishes a common understanding of objectives, roles/responsibilities, and the schedule , and the Lead CCA must (at minimum) review the schedule and confirm assessment scope with the OSC.

Option A is incomplete because team assignment is a C3PAO responsibility, but CAP’s “plan” emphasis here is broader framing: availability of personnel/evidence, documentation readiness, timing, and logistics. Option C is incorrect because CAP states C3PAOs are ultimately responsible for managing conflicts of interest and this responsibility cannot be delegated to the assessment team or the OSC. Option D is incorrect because CAP requires evaluation methods and evidence planning activities to be established during Phase 1 planning, not deferred until onsite work.

===========

In the context of a Cybersecurity Maturity Model Certification (CMMC) Level 2 Assessment, specific practices must be evaluated to ensure compliance with established security requirements. One such practice is AC.L2-3.1.19, which mandates the encryption of Controlled Unclassified Information (CUI) on mobile devices and mobile computing platforms.

Step-by-Step Explanation:

Requirement Overview:

Practice AC.L2-3.1.19 requires organizations to " Encrypt CUI on mobile devices and mobile computing platforms. " This ensures that any CUI accessed, stored, or transmitted via mobile devices is protected through encryption, mitigating risks associated with data breaches or unauthorized access.

Assessment of Provided Evidence:

During the assessment, the Organization Seeking Certification (OSC) provided an inventory list encompassing servers, workstations, and network devices. Notably, this list lacks any mention of mobile devices or mobile computing platforms.

Implications of the Omission:

The absence of mobile devices in the inventory suggests that the OSC may not have accounted for all assets that process, store, or transmit CUI. Without a comprehensive inventory that includes mobile devices, it ' s challenging to verify whether the OSC has implemented the necessary encryption measures for CUI on these platforms.

Assessment Determination:

Given the incomplete inventory, the evidence is insufficient to make a definitive scoring determination for practice AC.L2-3.1.19. The OSC must provide a detailed inventory that encompasses all relevant devices, including mobile devices and computing platforms, to demonstrate compliance with the encryption requirements for CUI.

In the CMMC 2.0 framework, the " Advanced " level is synonymous with CMMC Level 2 . The model is designed to be cumulative , meaning each higher level incorporates the requirements of the level(s) below it.

Cumulative Structure : For an organization to achieve a Level 2 Certification, it must demonstrate that it meets all 17 practices from Level 1 (Foundational) plus the additional 93 practices introduced at Level 2, totaling 110 practices (aligned with NIST SP 800-171 ).

Access Control (AC) Domain Breakdown :

Level 1 : Contains 4 AC practices (e.g., limiting system access to authorized users).

Level 2 : Contains 22 AC practices total. This includes the original 4 from Level 1 and 18 additional practices (e.g., controlling the use of privileged functions, limiting unsuccessful logon attempts).

Level 3 (Expert) : This level adds even more practices from NIST SP 800-172 . While Level 3 " contains " Level 2, the question asks specifically about what the Advanced Level (Level 2) contains. Therefore, it contains Level 1 and Level 2 practices.

Why other options are incorrect :

Option A : Level 2 is not just Level 1; it includes the additional NIST 800-171 requirements.

Option B : Level 3 practices are part of the " Expert " level, not the " Advanced " level.

Option D : The " Advanced " level (Level 2) does not include the " Expert " (Level 3) practices.

Reference Documents :

CMMC Model Overview (v2.0/v2.1) : Section 3.2, " Level 2: Advanced, " which explicitly states the level consists of the 110 practices from NIST SP 800-171, which includes the Level 1 requirements.

32 CFR Part 170 (CMMC Program Rule) : Defines the mapping of the 14 domains and the cumulative nature of the certification levels.

CMMC Level 2 Assessment Guide : Lists all 22 Access Control practices required for a Level 2 assessment.

The correct answer is D because the HQ Organization represents the legal entity associated with the contract obligation to deliver products or services. In assessment scoping, it is critical to separate the overall legal contracting entity from the specific Host Unit or operational segment that processes, stores, or transmits FCI or CUI. A Host Unit is the assessed operational environment or business unit within the organization where the relevant contract work and information handling occur. A Supporting Organization/Unit provides people, processes, or technology that support the Host Unit but is not the prime legal entity delivering the contractual product or service. A Commercial and Government Entity Code, or CAGE code, is an identifier associated with the entity; it is not itself the legal entity. CAP guidance requires the C3PAO to confirm the specific corporate legal entity being assessed and to solicit the associated CAGE code or codes. That distinction points to the HQ Organization as the contractual legal entity, while the CAGE code is only the identifier used to associate the entity with DoD systems. Reference/topics: CAP scoping, HQ Organization, Host Unit, CAGE code, legal entity confirmation.

The Certified Third-Party Assessment Organization (C3PAO) enters into a contractual relationship with the OSC. As part of that contract, the C3PAO maintains a non-disclosure agreement (NDA) to protect sensitive and proprietary information reviewed during the assessment.

Supporting Extracts from Official Content:

CAP v2.0, Roles and Responsibilities (§2.8): “The C3PAO maintains a non-disclosure agreement with the OSC to protect all sensitive information disclosed during the assessment.”

Why Option B is Correct:

Only the C3PAO contracts directly with the OSC and is bound to protect assessment data.

NIST, The Cyber AB (formerly CMMC-AB), and OUSD A & S do not enter NDAs directly with OSCs.

References (Official CMMC v2.0 Content):

CMMC Assessment Process (CAP) v2.0, Section on OSC–C3PAO agreements.

===========

Under the official CMMC Assessment Process (CAP) v2.0 , the OSC contracts directly with a C3PAO to arrange a Level 2 certification assessment, including the practical scope-of-work elements (timing, logistics, and the terms of performance). CAP v2.0 explicitly states that “The C3PAO shall execute a written contractual agreement for the CMMC Level 2 certification assessment with the OSC” and further clarifies that neither the Cyber AB nor DoD are parties to that contract.

Because the C3PAO is the assessment organization that conducts the certification assessment, it is also the entity the OSC coordinates with during the pre-assessment activities that shape the engagement and scope. CAP v2.0 places key Phase 1 responsibilities on the C3PAO/Lead CCA, including validating the OSC’s assessment scope against applicable scoping requirements and coordinating access to evidence and personnel needed for Phase 2.

By contrast, OUSD provides DoD-level oversight/policy, RPOs and the Cyber AB support the ecosystem, but they do not form the contractual relationship for a specific Level 2 certification assessment. CAP v2.0 is unambiguous that the contract (and any mutually agreed scope-of-work terms) is between the OSC and the C3PAO .

Understanding NIST SP 800-88 Rev. 1 and Media Sanitization

TheNIST Special Publication (SP) 800-88 Revision 1, Guidelines for Media Sanitization, provides guidance onsecure disposalof data from various types of storage media to prevent unauthorized access or recovery.

Three Categories of Data Disposal in NIST SP 800-88 Rev. 1

Clear

Useslogical techniquesto remove data from media, making it difficult to recover usingstandard system functions.

Example:Overwriting all datawith binary zeros or ones on a hard drive.

Applies to:Magnetic media, solid-state drives (SSD), and non-volatile memorywhen the media isreused within the same security environment.

Purge

Usesadvanced techniquesto make data recoveryinfeasible, even with forensic tools.

Example:Degaussinga magnetic hard drive orcryptographic erasure(deleting encryption keys).

Applies to:Media that is leaving organizational control or requires a higher level of assurance than " Clear " .

Destroy

Physicallydamages the mediaso that data recovery isimpossible.

Example:Shredding, incinerating, pulverizing, or disintegratingstorage devices.

Applies to:Highly sensitive data that must be permanently eliminated.

Why " A. Clear, Purge, Destroy " is Correct?

B. Clear, Redact, Destroy (Incorrect)– " Redact " is a term used for document sanitization,notdata disposal.

C. Clear, Overwrite, Purge (Incorrect)– " Overwrite " is a method within " Clear, " but it isnot a top-level categoryin NIST SP 800-88.

D. Clear, Overwrite, Destroy (Incorrect)– " Overwrite " is a sub-method of " Clear, " but " Purge " is missing, making this incorrect.

Conclusion

The correct answer isA. Clear, Purge, Destroy, as these are thethree official categoriesof data disposal inNIST SP 800-88 Revision 1.

Understanding the Role of Configuration Management (CM) in CMMC 2.0

TheConfiguration Management (CM) domainin CMMC 2.0 ensures that systems aresecurely configured and maintainedto prevent unauthorized or unnecessary changes that could introduce vulnerabilities. One key requirement in CM is torestrict, disable, or prevent the use of nonessential programsto reduce security risks.

Relevant CMMC 2.0 Practice:

CM.L2-3.4.1 – Establish and enforce security configuration settings for information technology products employed in organizational systems.

This practicerequires organizations to control system configurations, including the removal or restriction ofnonessential programs, functions, ports, and servicestoreduce attack surfaces.

The goal is tominimize exposure to cyber threatsby ensuring only necessary and approved software is running on the system.

Why is the Correct Answer CM (D)?

A. Access Control (AC) → Incorrect

Access Control (AC) focuses onmanaging user permissions and accessto systems and data, not restricting programs.

B. Media Protection (MP) → Incorrect

Media Protection (MP) deals withprotecting and controlling removable media(e.g., USBs, hard drives) rather than software or system configurations.

C. Asset Management (AM) → Incorrect

Asset Management (AM) is aboutidentifying and tracking IT assets, not configuring or restricting software.

D. Configuration Management (CM) → Correct

CM explicitly coverssecuring system configurationsbyrestricting nonessential programs, ports, services, and functions, making it the correct answer.

CMMC 2.0 References Supporting this Answer:

CMMC 2.0 Practice CM.L2-3.4.1(Security Configuration Management)

Requires organizations toenforce security configuration settingsandremove unnecessary programsto protect systems.

NIST SP 800-171 Requirement 3.4.1

Supportssecure configuration settingsandrestricting unauthorized applicationsto prevent security risks.

CMMC 2.0 Level 2 Requirement

This practice is aLevel 2 (Advanced) requirement, meaningorganizations handling Controlled Unclassified Information (CUI)must comply with it.
