How does ClusterXL Unicast mode handle new traffic?

A.
The pivot machine receives and inspects all new packets, and synchronizes the connections
with other members.

B.
Only the pivot machine receives all packets. It runs an algorithm to determine which member
should process the packets.

C.
All members receive all packets. The SmartCenter Server decides which member will process
the packets. Other members simply drop the packets.

D.
All cluster members process all packets, and members synchronize with each other.
