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

During aCMMC assessment, organizations must provide evidence to demonstrate compliance with requiredpractices and processes. Assessors evaluate this evidence based on two key criteria:

Adequacy– Does the evidence meet the intent of the security requirement?

Sufficiency– Is there enough evidence to reasonably conclude that the practice/process is effectively implemented?

These principles are outlined in theCMMC Assessment Process Guide, which provides a structured approach for evaluating compliance.

Step-by-Step Breakdown:✅1. Adequacy – Does the evidence fully meet the requirement?

Adequacyrefers to whether the evidence properly demonstrates that the security practice has been implemented as required.

Example: If an organization claims to enforceMulti-Factor Authentication (MFA), an assessor would checksystem configurations, login policies, and user authentication logsto confirm that MFA is actually in use.

✅2. Sufficiency – Is there enough evidence to support the claim?

Sufficiencymeans that there isenough supporting evidenceto prove compliance.

Example: If an organization providesonly one screenshot of an MFA login screen, that alone may not besufficient—additional logs, policies, and user records would help strengthen the case.

(B) Adequacy and Thoroughness❌

Thoroughnessis not a defined metric in CMMC evidence evaluation.

The focus is onwhether the evidence meets the requirement (adequacy)and if there isenough of it (sufficiency).

(C) Sufficiency and Thoroughness❌

Thoroughnessis not a recognized term in CMMC compliance validation.

Evidence must beadequate and sufficient, not just thorough.

(D) Sufficiency and Appropriateness❌

Appropriatenessis not a CMMC-defined criterion.

Thecorrect terms used in CMMC assessmentsareAdequacy(Does it meet the requirement?) andSufficiency(Is there enough proof?).

Why the Other Answer Choices Are Incorrect:

CMMC Assessment Process Guideexplicitly states that evidence must be evaluated based onadequacyandsufficiencyto confirm compliance with security practices.

Final Validation from CMMC Documentation:

Interview Selection in CMMC AssessmentsDuring aCMMC assessment, theLead Assessormust work with theOrganization Seeking Certification (OSC)to select personnel for interviews. The goal is to:

✅Verify that personnel understand andperform security-related practices.

✅Ensure that individuals canexplain how they implement CMMC requirements.

✅Gain insight intoactual cybersecurity operationsrather than just documented policies.

The best interviewees are those whodirectly engage with security practicesand canclearly explain how they perform their duties.

CMMC assessmentsrely on interviewsto validate that security practices areimplemented effectively.

Themost valuable intervieweesare those who canexplainhow security measures are appliedin day-to-day operations.

CMMC Assessment Process (CAP)emphasizes that assessors should speak tothose actively involved in security practicesrather than just senior management or policy owners.

Why "Providing Clarity and Understanding" Is KeyThus,option D is the correct choicebecause the Lead Assessor should prioritizeinterviewing personnel who can clearly explain how CMMC practices are implemented.

A. Have a security clearance.❌Incorrect.Security clearance is not a requirementfor CMMC assessments. The focus is onpractical implementation of security controls, not classified work.

B. Be a senior person in the company.❌Incorrect. Senior executives may not be involved in theactual implementation of security controls. The best interviewees are those whoperform the work, not just oversee it.

C. Demonstrate expertise on the CMMC requirements.❌Incorrect. Whileunderstanding CMMC is important, expertise alonedoes not guarantee practical knowledgeof security controls. The key is thatinterviewees must provide clarity on how they perform security tasks.

Why the Other Answers Are Incorrect

CMMC Assessment Process (CAP) Document– Guides interview selection based on personnel who perform security functions.

NIST SP 800-171 & CMMC 2.0– Emphasize that cybersecurity controls must beactively implemented, not just documented.

CMMC Official ReferencesThus,option D (Provide clarity and understanding of their practice activities) is the correct answeras per official CMMC assessment guidelines.

Assets that store, process, or transmit FCI or CUI are always in scope for CMMC. If a server with a cloud provider is used for long-term storage of FCI, that server is considered in scope because it directly holds covered data.

Supporting Extracts from Official Content:

CMMC Scoping Guide for Level 1: “Assets that store, process, or transmit FCI are in scope.”

CMMC Scoping Guide for Level 2: confirms the same rule applies for CUI.

Why Option A is Correct:

The server stores FCI, making it automatically in scope.

Option B is incorrect because long-term storage does not make an asset out of scope.

Option C is incorrect — Level 1 (FCI) does not require a Level 2 certified provider.

Option D is incorrect because encryption does not remove scope requirements.

===========

In CMMC scoping terminology, an HQ Organization is the entity legally responsible for contract performance and delivery of products or services.

Supporting Extracts from Official Content:

CMMC Scoping Guide: “HQ Organization is the legal entity responsible for the performance and delivery of contract requirements.”

Why Option D is Correct:

The HQ Org is legally accountable, while Host Units (option A/B) are subordinate entities.

Option C refers to shared services, not the HQ.
