Question: In a Fault Management scenario, when the `perceivedSeverity` field of an `alarmRecord` changes to a value other than CLEARED, which notification will be sent to subscribed MnS consumers if AlarmList.administrativeState=UNLOCKED?
Option 1: notifyChangedAlarm
Option 2: notifyClearedAlarm
Option 3: notifyCorrelatedNotificationChanged
Option 4: notifyAckStateChanged
Explanation: According to the specified behavior for Fault Management, when the `perceivedSeverity` field of an `alarmRecord` changes and the new value is not CLEARED (indicating an active alarm with a severity level), a `notifyChangedAlarm` notification is sent to each subscribed MnS consumer. This ensures that consumers are updated on changes to alarm severities, facilitating timely responses to network issues.
