Cyber AB CMMC-CCP Online Access

CMMC Level 2is designed to alignfullywithNIST SP 800-171, which consists of110 security controls (practices).

This meansall 110 practicesfrom NIST SP 800-171 are required for aCMMC Level 2 certification.

How Many Practices Are Included in CMMC Level 2?Breakdown of Practices in CMMC 2.0CMMC Level

Number of Practices

Level 1

17 practices(Basic Cyber Hygiene)

Level 2

110 practices(Aligned with NIST SP 800-171)

Level 3

Not yet finalized but expected to exceed 110

Since CMMC Level 2 mandatesall 110 NIST SP 800-171 practices, the correct answer isC. 110 practices.

A. 17 practices❌Incorrect.17 practicesapply only toCMMC Level 1, not Level 2.

B. 72 practices❌Incorrect. There is no CMMC level with72 practices.

D. 180 practices❌Incorrect. CMMC Level 2only requires 110 practices, not 180.

Why the Other Answers Are Incorrect

CMMC 2.0 Model– Confirms thatLevel 2 includes 110 practicesaligned withNIST SP 800-171.

NIST SP 800-171 Rev. 2– Outlines the110 security controlsrequired for handlingControlled Unclassified Information (CUI).

CMMC Official ReferencesThus,option C (110 practices) is the correct answer, as per official CMMC guidance.

Step 1: Understand the Definitions of Evidence Evaluation CriteriaTheCMMC Assessment Process (CAP)introduces two key criteria for evaluating evidence:

Adequacy– Does the evidencealign with the practice?

Sufficiency– Is the evidencecomprehensive enoughin terms ofcoverage across systems, users, and scope?

CAP v1.0 – Section 3.5.4:

“Evidence must be evaluated for bothadequacy(is it the right evidence?) andsufficiency(is there enough of it across all in-scope assets and areas?) to score a practice as MET.”

✅Step 2: Applying to the ScenarioIn the question, the Lead Assessor is asking the team toverify that evidence is sufficient across:

Domains

Practices

Host Units

Supporting Organizations

Enclaves

➡️ This is adirect reference to sufficiency, which evaluates whether thebreadth and depthof evidence is enough to make an informed judgment that the control is truly implemented across theentire assessed environment.

A. Adequacy✘ Adequacy refers to therelevanceof the evidence to the specific practice — not itscoverageacross scope.

B. Capability✘ Not a term used in evidence validation within CMMC CAP documentation.

D. Objectivity✘ While objectivity is important, it refers to theunbiased nature of assessment activities, not to theextent of evidence coverage.

❌Why the Other Options Are Incorrect

When an assessor evaluates whether the evidence is broad enough across all necessary systems, units, and enclaves to score a practice as MET, they are evaluatingsufficiency— one of the two core criteria for evidence validity in a CMMC assessment.

What is Required in the CMMC Assessment Kickoff and Opening Briefing?Before starting aCMMC assessment, theLead Assessormust present anopening briefingto ensure that theOrganization Seeking Certification (OSC)understands the assessment process.

Step-by-Step Breakdown:✅1. Overview of the Assessment Process

The Lead Assessormust explain the CMMC assessment methodology, including:

Theassessment objectives and scope

How theassessment team will review security controls

What to expectduring interviews, testing, and document review

This ensurestransparency and alignmentbetween the assessors and the OSC.

✅2. Why the Other Answer Choices Are Incorrect:

(A) Gathering Evidence❌

Evidence collection is part of the assessment butnot the primary topic of the opening briefing.

(B) Review of the OSC's SSP❌

While theSSP is a key document, reviewing it is part of the assessment,not the kickoff briefing.

(D) Examination of the artifacts for sufficiency❌

Artifact review happens laterin the assessment process,not during the kickoff.

TheCMMC Assessment Process Guidestates that theopening briefing must include an overview of the assessment process, ensuring the OSC understands the expectations and methodology.

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

✅C. Overview of the assessment process.

Understanding the CMMC-AB Code of Professional ConductTheCybersecurity Maturity Model Certification Accreditation Body (CMMC-AB), now referred to asThe Cyber AB, establishes aCode of Professional Conduct (CoPC)for all individuals involved in CMMC assessments, includingCertified Assessors (CAs), Certified Professionals (CPs), and C3PAOs (Certified Third-Party Assessment Organizations).

Thecore principlesoutlined in theCMMC-AB Code of Professional Conductinclude:

Responsibility

CMMC professionals must takefull accountabilityfor their actions, ensuring that assessments are conducted withintegrity and professionalism.

They mustadhere to all ethical and regulatory requirementsestablished by The Cyber AB and the DoD.

Confidentiality

CMMC professionals mustprotect sensitive information, includingControlled Unclassified Information (CUI)andFederal Contract Information (FCI).

They are required toadhere to non-disclosure agreements (NDAs)and avoid improper information sharing.

Information Integrity

All reports, findings, and recommendations in CMMC assessments must beaccurate, unbiased, and truthful.

Assessors mustavoid conflicts of interestand ensure that all data provided in an assessment isverifiable and free from misrepresentation.

Answer A (Incorrect): "Classification" is not a primary principle of the CMMC-AB CoPC. The focus is on protectingCUI and FCI, not on classification procedures.

Answer B (Incorrect): "Objectivity" is important, but it is not explicitly listed as one of the three core principles in theCMMC-AB Code of Professional Conduct.

Answer C (Incorrect): "Classification" is not a guiding principle in the CoPC.

Answer D (Correct):The Code of Professional Conduct explicitly emphasizes responsibility, confidentiality, and information integrity.

The correct answer isD. Responsibility, Confidentiality, and Information Integrity.

These principlesensure that all CMMC professionals maintain ethical standards and uphold the integrity of the certification process.
