Question: Under what conditions is an Alarm Record maintained in the AlarmList by the MnS (Management System) producer, considering both perceivedSeverity and ackState?
Option 1: Only when perceivedSeverity is "CLEARED" and ackState is "ACKNOWLEDGED".
Option 2: When perceivedSeverity is not "CLEARED", or when perceivedSeverity is "CLEARED" regardless of ackState.
Option 3: Exclusively when perceivedSeverity is not "CLEARED" and ackState is "UNACKNOWLEDGED".
Option 4: When perceivedSeverity is not "CLEARED", or when perceivedSeverity is "CLEARED" but ackState is not "ACKNOWLEDGED" and alarm acknowledgement by the consumer is supported.
Explanation: This option correctly combines both conditions for maintaining an active alarm record as per the specifications. An alarm remains active (and its record is maintained) if either its perceived severity is not yet cleared, or if it has been cleared but not acknowledged by the consumer, with the additional requirement that acknowledgement support by the consumer is necessary in the latter case. This ensures the MnS producer keeps track of all unresolved issues, whether pending clearance or awaiting acknowledgement after clearance.
