What is used to minimize the negative impact of an event?

A monitoring action plan specifies the predefined actions to be taken when a particular event or threshold is detected. These actions are designed to be automatic or semi-automatic responses aimed at restoring the service to a normal state or preventing further degradation. By defining these responses in advance, organizations can ensure a swift and effective reaction that directly minimizes the negative impact of the event on business operations and service quality.

A. An event correlation is a technique to analyze and link multiple events together; it does not, by itself, minimize impact.
B. A rule set is used to filter, categorize, and prioritize events for processing, which is a step before taking action to minimize impact.
C. A health model defines the normal operational state of a CI, helping to detect deviations (events), but it is not the plan for action.
