Understanding the "Verify Evidence and Record Gaps" Activity in a CMMC Assessment During aCMMC Level 2 Assessment, theAssessment Teamfollows a structured methodology toverify evidenceand determine whether theOrganization Seeking Certification (OSC)has met all required practices.
One of the key activities in this process is " Verify Evidence and Record Gaps " , which ensures that the assessment findings accurately reflect any missing or inadequate compliance evidence.
Step-by-Step Breakdown:
#1. Primary Intent: Identifying Gaps Between Required and Collected Evidence TheAssessment Teamcompares the evidence provided by the OSC against theCMMC practice requirements.
If evidence ismissing, insufficient, or inconsistent, assessors mustdocument the gapand describe what is lacking.
This ensures that compliance deficiencies are clearly identified, allowing the OSC to understand what must be corrected.
#2. How This Process Works in a CMMC Assessment
Assessorsreview collected documentation, system configurations, policies, and interview responses.
They verify that the evidencematches the expected implementationof a practice.
If gaps exist, they arerecordedfor discussion and potential remediation before assessment completion.
#3. Why the Other Answer Choices Are Incorrect:
(A) Map test and demonstration responses to CMMC practices.#
Incorrect:While mapping evidence to CMMC practices is part of the assessment, theprimary intentof the " Verify Evidence and Record Gaps " step is toidentify deficiencies, not just mapping responses.
(B) Conduct interviews to test process implementation knowledge.#
Incorrect:Interviews are a method used during evidence collection, but they arenot the primary focusof the verification and gap analysis step.
(C) Determine the one-to-one relationship between a practice and an assessment object.# Incorrect:The assessment teamreviews multiple sources of evidencefor each practice, and some practices require multiple assessment objects. The goal isnot a strict one-to-one mappingbut rathera holistic validation of compliance.
Final Validation from CMMC Documentation:
TheCMMC Assessment Process Guidestates that " Verify Evidence and Record Gaps " is the step where assessorscompare expected evidence against what has been provided and document discrepancies. This ensurestransparent assessment findings and remediation planning.
Thus, the correct answer is:
D). Identify and describe differences between what the Assessment Team required and the evidence collected.

Understanding CMMC 2.0 Incident Response Practices
TheIncident Response (IR) domaininCMMC 2.0 Level 2aligns withNIST SP 800-171, Section 3.6, which defines requirements forestablishing and maintaining an incident response capability.
Why "A. IR.L2-3.6.1: Incident Handling" is Correct?
The documentation provideddescribes an incident response capability that includes preparation, detection, analysis, containment, recovery, and user response activities.
IR.L2-3.6.1specifically requires organizations toestablish an incident handling processcovering:
Preparation
Detection & Analysis
Containment
Eradication & Recovery
Post-Incident Response
Why Other Answers Are Incorrect?
B). IR.L2-3.6.2: Incident Reporting (Incorrect)
Incident reporting focuses on reporting incidents to external parties (e.g., DoD, DIBNet),which isnot what the provided documentation describes.
C). IR.L2-3.6.3: Incident Response Testing (Incorrect)
Incident response testing ensures that the response process is regularly tested and evaluated,which isnot the primary focus of the documentation provided.
D). IR.L2-3.6.4: Incident Spillage (Incorrect)
Incident spillage specifically refers to CUI exposure or handling unauthorized CUI incidents,which isnot the scenario described.
Conclusion
The correct answer isA. IR.L2-3.6.1: Incident Handling, as the documentationattests to the establishment of an incident response capability.

CMMC Assessment Process (CAP) Guide

Under the official CMMC Assessment Process (CAP) v2.0 , the OSC contracts directly with a C3PAO to arrange a Level 2 certification assessment, including the practical scope-of-work elements (timing, logistics, and the terms of performance). CAP v2.0 explicitly states that "The C3PAO shall execute a written contractual agreement for the CMMC Level 2 certification assessment with the OSC" and further clarifies that neither the Cyber AB nor DoD are parties to that contract.
Because the C3PAO is the assessment organization that conducts the certification assessment, it is also the entity the OSC coordinates with during the pre-assessment activities that shape the engagement and scope.
CAP v2.0 places key Phase 1 responsibilities on the C3PAO/Lead CCA, including validating the OSC's assessment scope against applicable scoping requirements and coordinating access to evidence and personnel needed for Phase 2.
By contrast, OUSD provides DoD-level oversight/policy, RPOs and the Cyber AB support the ecosystem, but they do not form the contractual relationship for a specific Level 2 certification assessment. CAP v2.0 is unambiguous that the contract (and any mutually agreed scope-of-work terms) is between the OSC and the C3PAO .

The correct answer is D because the HQ Organization represents the legal entity associated with the contract obligation to deliver products or services. In assessment scoping, it is critical to separate the overall legal contracting entity from the specific Host Unit or operational segment that processes, stores, or transmits FCI or CUI. A Host Unit is the assessed operational environment or business unit within the organization where the relevant contract work and information handling occur. A Supporting Organization/Unit provides people, processes, or technology that support the Host Unit but is not the prime legal entity delivering the contractual product or service. A Commercial and Government Entity Code, or CAGE code, is an identifier associated with the entity; it is not itself the legal entity. CAP guidance requires the C3PAO to confirm the specific corporate legal entity being assessed and to solicit the associated CAGE code or codes. That distinction points to the HQ Organization as the contractual legal entity, while the CAGE code is only the identifier used to associate the entity with DoD systems.
