Explanation

Triage is the process that evaluates and classifies events to determine whether they rise to the level of an incident - it involves assessing severity, scope, and impact to decide how (or whether) to escalate and respond.

Why the distractors are wrong:

  • A (Threat intelligence reviews) provide context about known threats and adversaries but don't classify individual events as incidents.
  • C (Business Impact Analysis) is a planning activity used to identify critical business functions and recovery priorities - it's done before incidents occur, not during event classification.
  • D (End-user reporting) is an input that may surface potential events, but reporting alone doesn't classify anything; that determination requires triage.

Memory tip: Think of triage like an ER nurse deciding who needs a doctor vs. who can wait - events pile up constantly, and triage is the gatekeeping step that separates noise from real incidents.
