Comprehensive and Detailed in Depth Explanation:
The CAP requires verifying evidence currency, documenting gaps like undated screenshots (Option B).
Options A, C, and D misapply CAP evidence rules.
Extract from Official Document (CAP v1.0):
* Section 2.2 - Conduct Assessment (pg. 25):"Document lack of evidence verification, such as dates, as gaps and request additional verification." References:
CMMC Assessment Process (CAP) v1.0, Section 2.2.

Comprehensive and Detailed In-Depth Explanation:
AC.L2-3.1.11 involves "terminating user sessions after defined conditions." Specifications (documented artifacts like policies and plans-B, C, D) define these conditions and are examinable per NIST SP 800-171A.
Mechanisms (A) are technical implementations, not specifications, and are tested, not examined as documents. The CMMC guide distinguishes between examining policies and testing mechanisms.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), AC.L2-3.1.11: "Examine policies and plans; test termination mechanisms."
* NIST SP 800-171A, 3.1.11: "Specifications include policies, not mechanisms." Resources:

Comprehensive and Detailed in Depth Explanation:
Hashing evidence artifacts is the OSC's responsibility to ensure their integrity, not the Lead Assessor's. By performing this task, the Lead Assessor compromises the evidence package's integrity, violating the CoPC's Information Integrity principle. Option A (Professionalism) is not directly breached here. Option B (Confidentiality) is unrelated, as no disclosure occurred. Option C (Objectivity) is unaffected by this action.
Option D is the correct violation.
Extract from Official Document (CoPC):
* Paragraph 3.4(2) - Information Integrity (pg. 7):"Ensure that actions taken do not compromise the integrity of evidence packages, which is the responsibility of the OSC." References:
CMMC Code of Professional Conduct, Paragraph 3.4(2).

Comprehensive and Detailed In-Depth Explanation:
SC.L2-3.13.11 (5-point practice) requires full implementation for certification. Per CAP, a POA&M documents deficiencies but isn't a substitute for completion (A). Options B, C, and D contradict CMMC rules, as partial implementation or POA&M listing doesn't equate to Met status, especially for 5-point practices ineligible for POA&M deferral.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), SC.L2-3.13.11: "Full implementation required."
* CAP v5.6.1: "POA&M not a substitute for Met status."

Comprehensive and Detailed In-Depth Explanation:
CMMC practice AC.L2-3.1.19 requires that organizations "encrypt CUI on mobile devices and mobile computing platforms" to protect sensitive data from unauthorized access. To assess the implementation effectively, you need to interview personnel who have direct knowledge of and responsibility for the encryption measures on mobile devices. Personnel with access control responsibilities for mobile devices are best suited for this, as they are likely involved in configuring, managing, and enforcing encryption policies specific to mobile devices handling CUI. Executives may have a high-level overview but lack technical details. IT helpdesk staff typically handle basic troubleshooting and may not have insight into encryption implementation. HR staff focus on personnel management, not technical security controls. The CMMC Assessment Guide emphasizes interviewing individuals with operational responsibility for the specific control to verify implementation details.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), AC.L2-3.1.19: "Interview: Personnel with information security responsibilities; personnel with mobile device responsibilities; network and system administrators."
* NIST SP 800-171A, 3.1.19: "Interview personnel with responsibilities for encrypting CUI on mobile devices to determine the processes and mechanisms in place." Resources:
