A. Configure a core group bridge.

B. Configure a second active coordinator.

C. Decrease the memory on the machine.

D. Move the coordinator to another machine.

A system administrator has added a server cluster as a member of a service integration bus (SIB). The administrator needs to configure one messaging engine for each server in this cluster and to have a failover location for each messaging engine.

What should the administrator do to achieve the required design?
