Refer to the Exhibit.
Scenario : A multi-cluster architecture, with two geographically separated clusters (WAN-1 and
WAN-2), is being created. It will provide cross-cluster WAN HTTP session failover. The WAN-1
cluster is located in London and the WAN-2 cluster is located in New York 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. Four WebLogic Server instances will be running on each cluster distributed on two
physical machines, two WebLogic instances per physical machine. A database is configured on
each cluster for HTTP Session state failover between the clusters.
If the admin server for New York cluster crashes, what will be the effect on inter-cluster
communication between the two sites?
A.
There’s no effect on the inter-cluster communication between the two sites
B.
JDBC session flushing between two sites will be affected and will only be restarted on the
Admin server reboot.
C.
Intra-cluster multicasting will be affected and inter-cluster communication will slow down
between the sites.
D.
The Managed Servers will lose session stickiness and the server Health state will be changed
to suspend.
E.
Both c and d
