which server will this user be redirected to?

Consider a cluster of four servers: ServerA, ServerB, ServerC, and ServerD.
The cluster hosts a web application and is accessed using a proxy pug-in. This web application is
configured to use in-memory session replication.
A user is directed to ServerA. An HTTP session is established on ServerA and is also replicated to
ServerC. If ServerA subsequently fails, which server will this user be redirected to?

A.
none; the user will receive an error message

B.
ServerB

C.
ServerC

D.
ServerD

E.
Any other available server

Explanation:
To support automatic failover for servlet and JSP HTTP session states, WebLogic
Server replicates the session state in memory. WebLogic Server creates a primary session state
on the server to which the client first connects, and a secondary replica on another WebLogic
Server instance in the cluster. The replica is kept up-to-date so that it may be used if the server
that hosts the servlet fails. The process of copying a session state from one server instance to
another is called in-memory replication.
