Adaface Sample Weblogic Questions

We set up a multi-cluster architecture, with 2 geographically separated clusters (cluster-1 and cluster-2). It will provide cross-cluster WAN HTTP session failover. cluster-1 is located in France and the cluster-2 is located in California and is connected via a slow interconnect. The client request passes through a Global load balancer which load balances the request to local load balancers which eventually pass the load to WebLogic Server instances in the cluster. 4 WebLogic Server instances will be running on each cluster distributed on 2 physical machines, 2 WebLogic instances per physical machine. A database is configured on each cluster for HTTP Session state failover between the clusters. What will happen if all the servers hosted in the France cluster crash in the middle of an http session update?

A. The session will be regenerated on the California cluster without any session data loss, and a new primary server will be created using the secondary session data.
            
            B. The session will be regenerated on the California cluster but there could be a loss of session data; a new primary server will be created using the last known secondary session data.
            
            C. The session will not be regenerated on any cluster; the user will be redirected to the California cluster to create a new session.
            
            D. The session will be regenerated if the primary server on the France cluster is restarted.
            
            E. Both B and D
