A client accesses a web application named companystore that is running on WebLogic Server.
After adding several items to the shopping cart, the host server crashes. The client is automatically
redirected to another server by a proxy, but the shopping cart is now empty.
Which WebLogic Server feature would you enable to remedy this situation?
A.
Application Persistence
B.
Message Persistence
C.
Session Replication
D.
Dynamic Failover
E.
Stateful Pooling
Explanation:
In order for a cluster to provide high availability it must be able to recover from
service failures.
In clusters that utilize Web servers with WebLogic proxy plug-ins, the proxy plug-in handles
failover transparently to the client. If a server fails, the plug-in locates the replicated HTTP session
state on a secondary server and redirects the client’s request accordingly.
