Comprehensive and Detailed in Depth Explanation:
The CAP lists OSC-related inputs for ROM (Options A, C, D), but team education (Option B) is irrelevant to this estimate.
Extract from Official Document (CAP v1.0):
* Section 1.5 - Assessment Planning (pg. 16):"ROM inputs include OSC location, size, complexity, and readiness." References:

MP.L2-3.8.4 requires that CUI markings follow the media, meaning when electronic documents are printed, the original markings must carry over to the hard copy. Distribution lists or colored stamps are not specifically required.
Extract:
"Mark media containing CUI with the CUI designation indicators as required. When converting CUI from one medium to another, the original markings must be retained." Thus, the assessor should expect to see the original markings carried onto the printouts.

Comprehensive and Detailed In-Depth Explanation:
CMMC practice IA.L2-3.5.5 - Identifier Reuse requires organizations to "prevent reuse of identifiers for a defined period." The objectives are: [a] defining a period after which inactive identifiers are disabled, and [b] defining a period before reuse is allowed. The OSC meets both:
* Disables unused identifiers after 6 months (objective [a]),
* Prevents reuse for 12 months (objective [b]).
The scenario provides no evidence of deficiencies (e.g., reuse occurring before 12 months), and the process is automated and documented, fully satisfying the practice. Per the DoD Scoring Methodology, IA.L2-3.5.5 is a
1-point practice, scoring Met (+1) when fully implemented (B). Options C and D use incorrect point values (no 2-point or 5-point practices match this), and Not Met (A) requires evidence of failure.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), IA.L2-3.5.5: "Verify [a] a period is defined for disabling inactive identifiers, and [b] a period is defined preventing reuse."
* DoD Scoring Methodology: "1-point practice: Met = +1, Not Met = -1."
* NIST SP 800-171A, 3.5.5: "Examine policy and configs for defined disablement and reuse periods." Resources:

Comprehensive and Detailed in Depth Explanation:
The CAP requires documenting discrepancies between documented and actual processes as evidence gaps and assessing all evidence (Option B). Option A ignores documentation, Option C is premature, and Option D is consulting, which is not allowed.
Extract from Official Document (CAP v1.0):
* Section 2.2 - Conduct Assessment (pg. 25):"Document discrepancies between documented procedures and actual processes as evidence gaps and assess based on all findings." References:
CMMC Assessment Process (CAP) v1.0, Section 2.2.

The CMMC Assessment Process (CAP) states that deficiency correction is not permitted during the assessment. Practices must be evaluated based on their implementation at the time of assessment. If the OSC corrects deficiencies after assessment activities have begun, the changes cannot be considered in the scoring.
Extract:
"Deficiency correction during the assessment is not permitted. Practices are scored based on evidence available at the time of assessment activities." Thus, the correct next step is to score the practice as NOT MET.
