Which event delivery optimization option should you enable?

A.    Normal
B.    Custom
C.    Minimize Bandwidth
D.    Minimize Latency

Answer: D
Explanation:
Event Delivery Optimization Options
Normal
This option ensures reliable delivery of events and does not attempt to conserve bandwidth.
It is the appropriate choice unless you need tighter control over bandwidth usage or need forwarded events delivered as quickly as possible. It uses pull delivery mode, batches 5 items at a time and sets a batch timeout of 15 minutes.
Minimize Bandwidth
This option ensures that the use of network bandwidth for event delivery is strictly controlled.
It is an appropriate choice if you want to limit the frequency of network connections made to deliver events. It uses push delivery mode and sets a batch timeout of 6 hours. In addition, it uses a heartbeat interval of 6 hours.
Minimize Latency
This option ensures that events are delivered with minimal delay. It is an appropriate choice if you are collecting alerts or critical events. It uses push delivery mode and sets a batch timeout of 30 seconds.
