Important Cyber AB CMMC-CCP Exam Questions

Answer: C

Explanation:

Understanding the C3PAO Assessment Methodology

ACertified Third-Party Assessment Organization (C3PAO)is an entity authorized by theCMMC Accreditation Body (CMMC-AB)to conduct officialCMMC Level 2 assessmentsfor organizations seeking certification.

Key Requirement: CMMC Assessment Process (CAP)

C3PAOs must follow theCMMC Assessment Process (CAP), which outlines:

Theassessment methodologyfor evaluating compliance.

Evidence collectionprocedures (interviews, artifacts, testing).

Assessment scoring and reportingrequirements.

Guidance for assessorson executing standardized assessments.

Why 'CMMC Assessment Process' is Correct?

ISO 27001 (Option A)is an international standard forinformation security managementbut isnot the basis for CMMC assessments.

NIST SP 800-53A (Option B)providessecurity control assessments for federal systems, but CMMC assessments arebased on NIST SP 800-171.

GAO Yellow Book (Option D)is agovernment auditing standardused forfinancial and performance audits, not cybersecurity assessments.

CMMC Assessment Process (CAP) (Option C) is the correct answerbecause it defines how C3PAOs conduct CMMC assessments.

Official Reference from CMMC 2.0 Documentation

CMMC Assessment Process Guide (CAP)-- GovernsC3PAO assessment execution.

CMMC 2.0 Model Documentation-- RequiresC3PAOs to follow CAP proceduresfor assessments.

Final Verification and Conclusion

The correct answer isC. CMMC Assessment Process, as it is theofficial methodology all C3PAOs must follow when conducting CMMC assessments.

Answer: B

Explanation:

Understanding the Official CUI Registry

TheControlled Unclassified Information (CUI) Registryis theauthoritative sourcefor all federal agencies'CUI categories and indices. It is maintained by theNational Archives and Records Administration (NARA)and provides:

Acomprehensive listof CUI categories and subcategories.

Details onwho can handle, store, and share CUI.

Guidance onCUI marking and safeguarding requirements.

Why 'Official CUI Registry' is Correct?

TheOfficial CUI Registryis theonly federal resourcethat listsall CUI categories and agencies that use them.

32 CFR Section 2002(Option A) definesCUI policiesbut doesnotprovide a full listing of CUI categories.

Executive Order 13556(Option C) established theCUI Programbut doesnotmaintain an active list of categories.

The 'Official CMMC Registry' (Option D) does not exist---CMMC is a security framework, not a CUI classification system.

Breakdown of Answer Choices

Option

Description

Correct?

A . 32 CFR Section 2002

Incorrect--Defines CUI program rules butdoes not listcategories.

B . Official CUI Registry

Correct -- The registry contains the full list of CUI categories.

C . Executive Order 13556

Incorrect--Established the CUI program butdoes not maintain a category list.

D . Official CMMC Registry

Incorrect--No such registry exists; CMMC is a cybersecurity framework, not a CUI classification system.

Official Reference from CMMC 2.0 and Federal Documentation

National Archives (NARA) CUI Registry-- The authoritative source forall federal agency CUI categories.

32 CFR 2002-- Provides CUIpolicy guidancebut refers agencies to theOfficial CUI Registryfor classification.

Final Verification and Conclusion

The correct answer isB. Official CUI Registry, as it is theonly official source listing all federal agencies' CUI indices and categories.

Answer: C

Explanation:

DFARS clause 252.204-7012 establishes the safeguarding of Covered Defense Information (CDI), which aligns with CUI categories. The clause specifies that the DoD is responsible for determining whether information is Controlled Unclassified Information (CUI) and marking it accordingly before sharing it with contractors. Contractors do not make determinations about what constitutes CUI; they are responsible for safeguarding information once it is received and marked as CUI.

CMMC Model v2.0 Overview, December 2021

Answer: A

Explanation:

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.

Reference (Official CMMC v2.0 Content and Source Documents):

NIST SP 800-88 Rev. 1, Guidelines for Media Sanitization.

===========

Answer: D

Explanation:

This question aligns to the CMMC requirement to control information posted or processed on publicly accessible information systems, which appears in the CMMC Model Overview as AC.L1-3.1.22 (Control Public Information) and maps to FAR 52.204-21(b)(1)(iv) and NIST SP 800-171 Rev. 2 / r2 requirement 3.1.22.

NIST explains that publicly accessible systems are typically those accessible to the public without identification or authentication, and that individuals authorized to post nonpublic information (including CUI/FCI and proprietary information) are designated. It also emphasizes controlling what gets posted and ensuring nonpublic information is not exposed.

The most direct technical way to ''limit individuals who are authorized to post or process information'' is to implement role-based administrative access (least privilege) to the website/CMS/admin console---granting publish/edit privileges only to approved roles (e.g., ''Web Publisher,'' ''Content Approver''), and keeping all other users read-only or without access to posting functions. This directly enforces the requirement by using access control to restrict who can post/process content on the public system.

Options B and C are helpful procedural/administrative controls, but the question asks for technical means. Option A (cookies) does not control authorization to post; it's not an access control mechanism. Therefore, D is best.
