Cyber AB Updated CMMC-CCP Exam Questions and Answers by alessandro

TheCMMC Scoping Guide for Level 2outlines thatCUI assetsinclude systems, applications, and services thatstore, process, or transmitControlled Unclassified Information (CUI). These are the three core functions that defineCUI handlingwithin anOrganization Seeking Certification (OSC).

Step-by-Step Breakdown:✅1. CUI Assets Defined in CMMC

Stored:CUI is saved on hard drives, cloud storage, or databases.

Processed:CUI is actively used, modified, or analyzed by applications and users.

Transmitted:CUI is sent between systems via email, file transfers, or network communication.

✅2. Why the Other Answer Choices Are Incorrect:

(A) Received and transferred❌

Whilereceiving and transferring CUIis part of handling CUI, it does not fully cover all CUI asset responsibilities.

(C) Entered, edited, manipulated, printed, and viewed❌

These arespecific actionswithinprocessingbut do not coverstorage or transmission, which are also required for CMMC scoping.

(D) Located on electronic media, on system component memory, and on paper❌

While CUI can exist inelectronic and physical forms, CMMC scoping focuses onhow CUI is actively managed (stored, processed, transmitted)rather than where it physically resides.

TheCMMC Level 2 Scoping Guideconfirms thatCUI Assets are categorized based on their role in storing, processing, or transmitting CUI.

NIST SP 800-171also defines these three functions as key components of CUI protection.

Final Validation from CMMC Documentation:

TheCybersecurity Maturity Model Certification (CMMC) 2.0is primarily based on two key National Institute of Standards and Technology (NIST) Special Publications:

NIST SP 800-171– "Protecting Controlled Unclassified Information (CUI) in Nonfederal Systems and Organizations"

NIST SP 800-172– "Enhanced Security Requirements for Protecting Controlled Unclassified Information: A Supplement to NIST Special Publication 800-171"

NIST SP 800-171

This document is thecore foundationof CMMC 2.0 and establishes the security requirements for protectingControlled Unclassified Information (CUI)in non-federal systems.

The 110 security controls fromNIST SP 800-171 Rev. 2are mapped directly toCMMC Level 2.

NIST SP 800-172

This supplement includesenhanced security requirementsfor organizations handlinghigh-value CUIthat faces advanced persistent threats (APTs).

These enhanced requirements apply toCMMC Level 3under the 2.0 model.

B. DFARS, FIPS 100, and NIST SP 800-171→Incorrect

WhileDFARS 252.204-7012mandates compliance withNIST SP 800-171,FIPS 100 does not existas a relevant cybersecurity standard.

C. DFARS, NIST, and Carnegie Mellon University→Incorrect

CMMC is aligned with DFARS and NIST but isnot developed or directly influenced by Carnegie Mellon University.

D. DFARS, FIPS 100, NIST SP 800-171, and Carnegie Mellon University→Incorrect

Again,FIPS 100 is not relevant, andCarnegie Mellon Universityis not a defining entity in the CMMC framework.

CMMC 2.0 Scoping Guide (2023)confirms thatCMMC Level 2 is entirely based on NIST SP 800-171.

CMMC 2.0 Level 3 Draft Documentationexplicitly referencesNIST SP 800-172for enhanced security requirements.

DoD Interim Rule (DFARS 252.204-7021)mandates that organizations meetNIST SP 800-171 for CUI protection.

Reference and Breakdown:Eliminating Incorrect Answer Choices:Official CMMC 2.0 References Supporting the Answer:Final Conclusion:The CMMC 2.0 model is derivedsolely from NIST SP 800-171 and NIST SP 800-172, makingAnswer A the only correct choice.

ACMMC Level 2 Assessmentis conducted by aC3PAO (Certified Third-Party Assessment Organization)to determine whether theOrganization Seeking Certification (OSC)meets all required110 NIST SP 800-171 controls.

Before submitting the results, theC3PAO must complete a final briefing between the Lead Assessor and the OSCto review findings and clarify any concerns.

A. Pay an assessment submission fee→Incorrect

There is no mandatory submission fee for assessment results.Fees apply to the assessment process, not submission.

B. Complete an internal review of the results→Incorrect

While internal reviews are encouraged, they arenot a required step before submissionin CMMC assessment procedures.

C. Notify the CMMC-AB that submission is forthcoming→Incorrect

TheC3PAO submits results to the CMMC-AB through the CMMC eMASS system, but prior notification isnot a required procedural step.

D. Coordinate a final briefing between the Lead Assessor and the OSC→Correct

According toCMMC Assessment Process (CAP) guidelines, theLead Assessor must conduct a final briefing with the OSCbefore submitting the results.

This briefing ensures transparency, provides OSC with insight into the findings, and allows for final clarifications.

CMMC Assessment Process (CAP) v1.0

Requires afinal briefing between the Lead Assessor and the OSC before submitting assessment results.

CMMC-AB and C3PAO Process Requirements

TheLead Assessor must communicate final findings with the OSC before submission to CMMC-AB.

Analysis of the Given Options:Official References Supporting the Correct Answer:Conclusion:The correct answer is:

✅D. Coordinate a final briefing between the Lead Assessor and the OSC.

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

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.

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.

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