Question: Under what condition is a "Comment Added" notification generated by a Management and Network Service (MnS) producer in relation to an Alarm List?
Option 1: When a new AlarmInformation instance is created in the AlarmList.
Option 2: When a Comment instance is added to an existing AlarmInformation instance in the AlarmList, provided the MnS producer supports the setComment operation.
Option 3: Upon removal of a Comment from an AlarmInformation instance within the AlarmList.
Option 4: During periodic updates of all AlarmInformation instances in the AlarmList.
Explanation: This is correct because, as specified, the "Comment Added" notification is triggered specifically when a new Comment instance is linked to an existing AlarmInformation instance. Moreover, this functionality is contingent upon the MnS producer’s support for the setComment operation, ensuring seamless management and orchestration of alarm comments. This highlights the importance of conditional support for specific operations in telecom network management.
