What is the best implementation solution?

As the technical lead for your project, you have been asked to recommend a new solution to

handle frequently increasing loads on your applications. The Weblogic 12.1.2 domain
currently runs with two clusters of three servers with request being filtered and passed by a
proxy server that users the round –robin algorithm. However, the load sometimes exceeds
the maximum capacity of all these servers combined but your domain lacks in scalability.
What is the best implementation solution?

A.
Addathird cluster and spread existing serverinstances across the clusters.

B.
Modify the proxy serverload balancing algorithm to weightbased.

C.
Configure dynamicclusters and specify the number of serverinstances you anticipate at
needing at peak load.

D.
Tune work managers to optimize work.

E.
Replace the softwareload balancer with a hardware load balancer.
