Question 4
You have been tasked with deploying and targeting a new application to every server in a WebLogic cluster. Some servers are running on machines that have access to a common shared file system, while other servers do not have that same access. Currently, the default deployment staging mode for all servers in the cluster is set to STAGE however, you wish to avoid having the AdminServer automatically copy the application to the servers (in that cluster) with shared file system access. Which two approaches would satisfy the above requirement? (Choose two.)
A.
The machines that host the cluster should have similar processing power, disk space, and memory.
A.
Change the default deployment staging mode for all servers to EXTERNAL_STAGE, and then copy the application to all servers.
B.
The cluster should include at least one configurable server.
B.
Change the default deployment staging mode for the servers with access to the shared file system to NO_STAGE, then copy the application to the shared file system.
C.
The cluster should use unicast communication.
C.
Change the staging mode of the application to EXTERNAL_STAGE when you are deploying it to the cluster.
D.
All servers in the cluster should be assigned to the same WebLogic machine.
D.
Leave the default deployment staging mode for all servers as STAGE, but copy the application to the shared file system prior to deployment.
