Question: Under what condition is the (now deprecated) notification for a change in alarm severity generated by the MnS (Management Network Service) producer, according to 3GPP fault management principles?
Option 1: When the perceivedSeverity of an existing AlarmRecord changes to "CLEARED" or any other value.
Option 2: When a new AlarmRecord is created with a perceivedSeverity other than "CLEARED".
Option 3: When the perceivedSeverity of an existing AlarmRecord changes, excluding changes to the value "CLEARED".
Option 4: Only when the perceivedSeverity changes from "CLEARED" to another severity level.
Explanation: This is correct because, as per the given context, the notification in question is specifically generated when there's a change in the perceivedSeverity of an existing AlarmRecord, with the explicit exception of changes to the "CLEARED" state. This aligns with standard fault management practices where severity updates (excluding clearance) trigger notifications for timely response.
