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

The correct answer is C because the CMMC physical protection requirement focuses on protecting areas where in-scope information systems, equipment, and controlled environments are located. CMMC Level 2 requirement PE.L2-3.10.3, Escort Visitors , requires the organization to “escort visitors and monitor visitor activity.” The official CMMC Level 2 Assessment Guide states that the assessment objectives include determining whether visitors are escorted, visitor activity is monitored, physical access audit logs are maintained, and physical access devices are controlled and managed. The same guide explains that individuals with permanent physical access authorization credentials are not considered visitors, and that audit logs can be used to monitor visitor activity.

For CMMC purposes, the key issue is whether the visitor could physically access organizational systems, equipment, FCI, CUI, or the respective operating environment. A general corporate area that is outside the controlled environment may not require the same escort rule unless it provides access to in-scope assets. However, the controlled environment must be protected from unauthorized physical access. Therefore, visitors should be escorted in the controlled environment, where FCI/CUI systems or related assets may be present. Option A is incorrect because CMMC requires visitor escorting. Option B reverses the protection priority. Option D is overly broad for this question because it does not distinguish between a general corporate area and the controlled environment defined in the DAP.

Understanding Evidence Sufficiency in CMMC Level 2 Assessments

During aCMMC Level 2 Assessment, theLead Assessormust determine whether the evidence collected for each practice issufficientto support an assessment finding. This aligns with theCMMC Assessment Process (CAP) Guide, which requires assessors to evaluate:

Examinations– Reviewing documents, configurations, and system records.

Interviews– Speaking with personnel to confirm implementation and understanding.

Testing– Observing security controls in action to validate effectiveness.

To determine whether evidence issufficient, the assessor ensures that it:

Directly supports the assessment objective.

Demonstrates that the practice is consistently implemented.

Can be independently verified.

Why Option B (Sufficiency) is Correct

Sufficiencyrefers to whetherenoughevidence has been collected to make an accurate determination about compliance.

Option A (Adequacy)is incorrect because adequacy relates tothe qualityof evidence, while sufficiency focuses on whetherenoughevidence exists.

Option C (Process Mapping)is incorrect because process mapping is used for understanding workflows but is not an assessment verification method.

Option D (Assessment Scope)is incorrect because defining the scope happensbeforeevidence collection, during the planning phase.

Final Verification

Since theLead Assessor is ensuring enough evidence is available to verify compliance, the correct answer isOption B: Sufficiency.

The Lead Assessor has the authority to make the final determination in situations where assessors cannot agree on a rating. CAP specifies that the Lead Assessor ensures consistency, resolves disputes, and provides the authoritative interpretation during the assessment process. Escalation to the CMMC-AB or Quality Assurance would only occur in rare post-assessment review cases, not during an active assessment.

Step 1: Understanding CMMC Level 1 Self-Assessment Scope

CMMC Level 1applies toFederal Contract Information (FCI)systems.

Any system or device that is connected to an FCI-handling network is within the assessment scopebecause it canintroduce vulnerabilitiesinto the environment.

Step 2: Why the Thermostat is in Scope

TheWi-Fi-enabled thermostat is connected to the FCI network, meaning it haspotential accessto sensitive contract-related data.

PerCMMC Scoping Guidance, this type of device is classified as aRestricted Information System (Restricted IS)—devices that do not store, process, or transmit FCI but areconnected to networks that do.

Restricted IS must be accounted for in the self-assessment scope to ensure they do not compromise security controls.
