Which of the following Availability Management activities are considered to be proactive as opposed to reactive? (1) Risk assessment (2) Testing of resilience mechanisms (3) Monitoring of component…

Monitoring is a reactive activity because it responds to availability events as they occur rather than preventing them, so not all three are proactive.

Risk assessment proactively identifies potential threats to availability before they cause disruption, and testing resilience mechanisms proactively validates that failover and recovery capabilities work as designed. Monitoring component availability, while important, is reactive because it detects availability issues as they happen rather than preventing them.

Monitoring (3) is reactive, not proactive, because it detects and reports availability conditions in real time rather than anticipating or preventing failures.

Risk assessment (1) is clearly proactive as it identifies and mitigates risks before incidents occur, so it must be included alongside testing of resilience mechanisms.
