A customer is having performance problems and needs to understand how to resolve these
performance issues. Their environment runs a single Java Virtual Machine (JVM).
How can clustering help with the performance issues?

A.
Clustering provides a means to spread some of the workload across multiple heap spaces.

B.
Clustering speeds garbage collection by having more garbage collectors to purge the
application space.

C.
Clustering creates multiple TCP/I P ports for a single JVM to allow for more connections to the
application.

D.
Clustering provides failover so that the failure of an overburdened application server can be met
by a hot standby cluster member.
