You are in the process of planning a deployment in which a single WebLogic cluster will host a
web application. There are several options to consider.
Which is not a valid decision?
A.
Proxyplug-inorhardwareload balancer
B.
Configured or dynamic cluster
C.
ReplicatedorpersistentHTTP sessions
D.
Unicast or multicast communication
E.
Single or multiple domains
E
NOT VALID and good anwser is : E
VALID ARE : A/ B/ C/ D/
Proxy plug-in : existing
Explanation : Load Balancing with a Proxy Plug-in
The WebLogic proxy plug-in maintains a list of WebLogic Server instances that host a clustered servlet or JSP, and forwards HTTP requests to those instances on a round-robin basis. This load balancing method is described in Round Robin Load Balancing.
Hardware LB : Load Balancer Configuration Requirements
If you choose to use load balancing hardware instead of a proxy plug-in, it must support a compatible passive or active cookie persistence mechanism, and SSL persistence.

Active Cookie Persistence

I am not 100% sure .. but I think you cannot create a single Weblogic Cluster un more than 1 domain … so answer is E
A
Proxy plug-in or hardware load balancer is not necessary for single cluster
I think about it and change my opinion, the correct is E.
Even though the single cluster, the “Single or multiple domains” is more correct.
I think is E because a cluster can be in multiple domains. But is true, I have questions about A too.
I choice “E”
