The CMMC Assessment Process (CAP) defines four methods: Examine, Interview, Test, and Observe.
* Interview Method: Involves discussions with personnel to gather evidence about the implementation of practices.
* In this case, the CCA is discussing with the system administrator to understand processes, which clearly aligns with the Interview method.
Extract:
"Interview: The assessor uses discussions with personnel to obtain evidence about how practices are implemented within the OSC's environment." Reference: CMMC Assessment Guide - Level 2; CMMC Assessment Process (CAP).

Comprehensive and Detailed in Depth Explanation:
The CAP prioritizes data security in virtual assessments, requiring documentation of techniques, risks, mitigations, and protection measures for sensitive information like CUI and FCI. Option A (training) is secondary to security documentation. Option C (scheduling) is logistical, not a security priority. Option D (encryption) is important but part of broader protection measures under Option B, which is the highest priority per CAP.
Extract from Official Document (CAP v1.0):
* Section 1.6.3 - Virtual Data Collection (pg. 21):"The highest priority is recording the use of virtual data collection techniques, including risks, mitigations, and how CUI, FCI, and OSC proprietary information will be managed and protected." References:

Comprehensive and Detailed Explanation:
The CMMC Assessment Process (CAP) outlines a phased approach, with Phase 1 (Plan and Prepare) requiring the Lead Assessor to determine the feasibility of conducting the assessment afterreceiving the final scope and documentation. This step involves validating the scope's accuracy and ensuring resources and conditions are adequate before proceeding. Option B skips this critical planning step. Option C misplaces the C3PAO's role, as the Lead Assessor validates the scope, not the C3PAO. Option D is a subsequent task but not the immediate next step. A is correct per the CAP sequence.
Reference:
CMMC Assessment Process (CAP) v1.0, Section 2.1 (Phase 1: Plan and Prepare), p. 7: "The Lead Assessor determines the feasibility of conducting the assessment based on the provided scope."

AC.L2-3.1.21 requires that the use of portable storage devices be restricted and explicitly authorized. The described process covers labeling and limiting use but does not include documented management authorization.
Extract:
"Restrict the use of portable storage devices on external systems. Authorization for use must be formally documented and approved by management." Thus, the missing element is recorded management authorization.

Comprehensive and Detailed in Depth Explanation:
NIST SP 800-171A defines Assessment Objects as items assessed (specifications, mechanisms, activities, individuals). "Examine" (Option D) is an assessment method, not an object, per NIST and CMMC guidelines.
Options A, B, and C are valid objects, making Option D the correct answer.
