QUESTION: 3
A highly available WebLogic cluster in UNIX is configured for automatic server migration. Node
Managed is configured on both machines to start managed servers.

How should you simulate a managed server failure to test whether automatic server migration is
working?

A. Shut down the managed server from the WebLogic console.
B. Shut down the managed server using the WLST command through Node Manager.
C. Run "kil -9" once to kil the managed server process.
D. Run "kil -9" to kil the managed server process, and run "kil -9" one more time if the
managed server is restarting.

renew their leases. The failed servers wil then be automatical y migrated to the machines in the
majority partition.
