Q33. Which are true about Exalogic support for WebLogic Server applications? (Choose two) 

A. WebLogic Server uses a parallel muxer with smaller packet sizes to reduce processing overhead. 

B. Replication of servlet session/state for failover is a great example of where WebLogic has been further engineered to take advantage of theExalogicplatform 

C. WebLogic Server uses SDP over InfiniBand for data transfer between servers in a cluster. 

D. A single muxer is used for intra-cluster data transfer as it can more effectively utilize the bandwidth provided by InfiniBand. 

Answer: B,C 

Explanation: 

Replication of servlet session/state for failover is a great example of where WebLogic has been furtherengineered to take advantage of theExalogicplatform. In addition, WebLogic Server uses SDP overInfiniBand for data transfer between servers in a cluster.
