CMMC-CCP Exam Results

The term that describes"the prevention of damage to, protection of, and restoration of computers and electronic communication systems/services, including information contained therein, to ensure its availability, integrity, authentication, confidentiality, and non-repudiation"isCybersecurity.

Step-by-Step Breakdown:✅1. Cybersecurity Defined

Cybersecurityfocuses onprotecting networks, systems, and datafrom cyber threats.

It includes measures to ensure:

Availability(data is accessible when needed).

Integrity(data is accurate and unaltered).

Authentication(verifying users' identities).

Confidentiality(ensuring only authorized access).

Non-repudiation(preventing denial of actions).

The definition in the questionaligns directly with cybersecurity principles, making it the best answer.

✅2. Why the Other Answer Choices Are Incorrect:

(B) Data Security❌

Data securityfocusesspecificallyon protectingstored information(e.g., encryption, access controls), but cybersecurity is broader—it includesnetworks, systems, and communication services.

(C) Network Security❌

Network securityis asubset of cybersecuritythat focuses on protectingnetwork infrastructure(e.g., firewalls, intrusion detection systems).

The definition in the question includesmore than just networks, so cybersecurity is the better choice.

(D) Information Security❌

Information security (InfoSec)is related but broader than cybersecurity.

InfoSeccoversphysical and organizational security(e.g., policies, procedures) in addition todigital protections.

CMMC and NIST SP 800-171 define cybersecurityas the protection ofsystems, networks, and data from cyber threats.

DoD Cybersecurity Definitions(aligned with NIST) confirm that cybersecurity is the term thatbest fits the definition in the question.

Final Validation from CMMC Documentation:

Understanding FAR Clause 52.204-21TheFederal Acquisition Regulation (FAR) Clause 52.204-21is titled"Basic Safeguarding of Covered Contractor Information Systems."This clause establishesminimum cybersecurity requirementsforfederal contractorsthat handleFederal Contract Information (FCI).

Key Purpose of FAR Clause 52.204-21Theprimary objectiveof FAR 52.204-21 is to ensure that contractors applybasic cybersecurity protectionsto theirinformation systemsthat process, store, or transmitFCI. Theseminimum safeguarding requirementsserve as abaseline security standardfor contractors doing business with theU.S. government.

FAR 52.204-21 doesnotrequire contractors to install specific cybersecurity tools (eliminating option A).

Itoutlines only the minimum safeguards, notallcybersecurity controls needed for complete security (eliminating option B).

CMMC certification isnotmandated by this clause alone (eliminating option D).

Instead, it establishesa baseline "standard of care"that all federal contractorsmust followto protectFCI(making option C correct).

Why "Minimum Standard of Care" is Correct?Breakdown of Answer ChoicesOption

Description

Correct?

A. It directs all covered contractors to install the cybersecurity systems listed in that clause.

❌Incorrect–The clause doesnotspecify tools or require specific cybersecurity systems.

B. It describes all of the safeguards that contractors must take to secure covered contractor IS.

❌Incorrect–It only setsminimumrequirements, notall possiblesecurity measures.

C. It describes the minimum standard of care that contractors must take to secure covered contractor IS.

✅Correct – The clause defines basic safeguards as a minimum security standard.

D. It directs covered contractors to obtain CMMC Certification at the level equal to the lowest requirement of their contracts.

❌Incorrect–FAR 52.204-21 doesnot mandateCMMC certification; that requirement comes from DFARS 252.204-7012 and 7021.

Minimum Safeguarding Requirements Under FAR 52.204-21The clause defines15 basic security controls, which align withCMMC Level 1. Some examples include:

✅Access Control– Limit access to authorized users.

✅Identification & Authentication– Authenticate system users.

✅Media Protection– Sanitize media before disposal.

✅System & Communications Protection– Monitor and control network connections.

FAR 52.204-21– Establishes thebasic safeguarding requirementsfor FCI.

CMMC 2.0 Level 1– Directly aligns withFAR 52.204-21 controls.

Official References from CMMC 2.0 and FAR DocumentationFinal Verification and ConclusionThe correct answer isC. It describes the minimum standard of care that contractors must take to secure covered contractor IS.This aligns withFAR 52.204-21 requirementsas abaseline security standard for FCI.

TheCMMC Assessment Guideis the best source for determining the sources of evidence for a given practice because it provides specific guidance on how organizations should implement and demonstrate compliance with CMMC practices. Each CMMC level has its own assessment guide (e.g.,CMMC Assessment Guide – Level 1, Level 2), detailing expected evidence and assessment procedures.

CMMC Assessment Guide (Primary Source for Evidence)

TheCMMC Assessment Guideexplicitly outlines the evidence required to verify compliance with each practice.

It provides detailed instructions on assessment objectives, clarifying what assessors should look for when determining compliance.

The guide breaks down each practice intoassessment objectives, helping organizations prepare appropriate documentation and artifacts.

Other Documents and Why They Are Not the Best Choice:

NIST SP 800-53 (Option A)

WhileNIST SP 800-53provides a comprehensive catalog of security and privacy controls, it does not focus on CMMC-specific evidence requirements.

It serves as a foundational cybersecurity framework but does not define the specific artifacts required for CMMC assessment.

NIST SP 800-53A (Option B)

NIST SP 800-53Aprovides guidance on assessing security controls but is not tailored to the CMMC framework.

It includes general control assessment procedures, but theCMMC Assessment Guideis more precise in defining the evidence needed for CMMC compliance.

CMMC Assessment Scope (Option C)

TheCMMC Assessment Scopedocument outlines which systems, assets, and processes are subject to assessment.

While important for defining boundaries, it does not provide details on specific evidence requirements for each practice.

CMMC Assessment Guide (Level 2) – Section on "Assessment Objectives"

This document details how evidence is collected and evaluated for each CMMC practice.

Example: ForAC.L2-3.1.1 (Access Control – Limit System Access), the guide specifies that assessors should verify documented policies, system configurations, and audit logs.

CMMC Model Overview (Official DoD Documents)

Emphasizes thatCMMC Assessment Guidesare the official reference for determining sources of evidence.

Detailed Justification:References from Official CMMC Documents:Conclusion:TheCMMC Assessment Guideis the most authoritative source for determining the required evidence for a given practice in CMMC assessments. It provides detailed breakdowns of assessment objectives, required artifacts, and verification steps necessary for compliance.

Which NIST SP Defines the Assessment Procedures for CMMC?CMMC Level 2 isdirectly based on NIST SP 800-171, and the assessment procedures used in CMMC assessments are derived fromNIST SP 800-171A.

Step-by-Step Breakdown:✅1. NIST SP 800-171A Defines Assessment Procedures

NIST SP 800-171Ais titled"Assessing Security Requirements for Controlled Unclassified Information (CUI)".

It providesdetailed assessment objectives and test proceduresfor evaluating compliance withNIST SP 800-171 security requirements, whichCMMC Level 2 is fully aligned with.

CMMC Assessors use 800-171Aas abaseline for assessing the effectiveness of security controls.

✅2. Why the Other Answer Choices Are Incorrect:

(A) NIST SP 800-53❌

800-53 defines security controlsfor federal information systems, but it doesnot provide assessment procedures specific to CMMC.

(B) NIST SP 800-53A❌

800-53A provides assessment procedures for 800-53 controls, butCMMC is based on NIST SP 800-171, not 800-53.

(C) NIST SP 800-171❌

800-171 defines security requirements, butit does not provide assessment procedures. Theassessment proceduresare in800-171A.

TheCMMC Assessment Guide (Level 2)explicitly states that assessment procedures are derived fromNIST SP 800-171A.

Final Validation from CMMC Documentation:Thus, the correct answer is:
