B: The Administration Server uses the machine definition in conjunction with the Node Manager application to start remote WebLogic Server instances.
E: By default, WebLogic Server attempts to create session state replicas on a different machine than the one that hosts the primary session state. You can further control where secondary states are placed using replication groups. A replication group is a preferred list of clustered servers to be used for storing session state replicas.
Using the WebLogic Server Console, you can define unique machine names that will host individual server instances. These machine names can be associated with new WebLogic Server instances to identify where the servers reside in your system.
Machine names are generally used to indicate servers that run on the same machine.
