An EJB application is targeted to a cluster. Remote EJB clients can therefore take advantage of
WebLogic Server’s load balancing and failover capabilities.
However, a proxy server exists between the clients and the cluster, which performs IP address
translation. Which cluster attribute should you modify to ensure that load balancing and failover
work correctly?
A.
Multicast Address
B.
Persistent Store
C.
Cluster Address
D.
Migration Basis
E.
Replication Channel
Explanation:
Note:
Updating Proxy Service Configurations for an Expanded Cluster
If your AquaLogic Service Bus configuration includes one or more proxy services that use JMS
endpoints with cluster addresses, then you must also perform the following procedure using the
AquaLogic Service Bus Console after adding the new managed server to the cluster:
The proxy services are now configured for operation in the extended domain.

C
B 🙁
Which answer is B or C?
A
If the multicast address is not set correctly, then the cluster members won’t be able to communicate with each other, thus load balancing and failover features won’t work correctly either.
I think the answer is C. Unicast address could be used for failover.
C
C is correct, I passed exam with 100% score
