Why do event management systems use device-generated events (that is, TRAP, syslog) instead
of poll-based?
A.
because alarms are considered events in most NMS systems
B.
because devices maintain their own current alarm state
C.
because there would be a delay between polling cycles that prevents alarm management in
near-real time
D.
because alarm management is generally poll-based and is not event-based
E.
because poll-based systems require acknowledgments and retransmission capability
