This lesson develops practical capability in CMMC Model, Levels, Domains, Practices, Assessment Ecosystem, and Accountability for PECB CMMC Foundations (PECB). Activities reflect a defense supplier defining its CMMC boundary and preparing people, processes, technology, and evidence for assessment, so decisions are judged through observable evidence, accountable ownership, and accepted outcomes.
The instructor demonstrates cMMC Model, Levels, Domains, Practices, Assessment Ecosystem, and Accountability within a defense supplier defining its CMMC boundary and preparing people, processes, technology, and evidence for assessment, records each material decision in CMMC model and responsibility map, and contrasts the accepted state with the controlled exception where the CUI boundary excludes an unmanaged collaboration service.
Complete a controlled exercise focused on cMMC Model, Levels, Domains, Practices, Assessment Ecosystem, and Accountability. Establish the expected outcome, produce CMMC model and responsibility map, introduce the case where the CUI boundary excludes an unmanaged collaboration service, apply a reversible correction, and rerun the original acceptance checks.
When the CUI boundary excludes an unmanaged collaboration service, separate the visible symptom from its governing requirement, verify source evidence and recent changes, test one reversible hypothesis, and update CMMC model and responsibility map only after the corrected state passes normal and boundary checks.
Learners can apply CMMC Model, Levels, Domains, Practices, Assessment Ecosystem, and Accountability, explain the choices made, and defend the result using CMMC model and responsibility map.
