CCFA: CrowdStrike Certified Falcon Administrator

A host is flagged inactive when it stops sending heartbeats to the Falcon cloud, and inactive hosts remain visible in the Host Management and Trash pages for 90 days before being automatically and permanently removed. This 90-day retention is the value taught in the CCFA curriculum and matches both the automated key and the independent solver. The shorter values (15, 45, 120 days) are distractors that do not correspond to the visibility/retention window.
