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? 

Answer options:

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 "kill -9" once to kill the managed server process.
D. Run "kill -9" to kill the managed server process, and run "kill -9" one more time if the managed server is restarting.

A

Note: * It is recommended that you shutdown WebLogic Server instances through the Administration Console. * If automatic server migration is enabled, the servers are required to contact the cluster leader and renew their leases periodically. Servers will shut themselves down if they are unable to renew their leases. The failed servers will then be automatically migrated to the machines in the majority partition.
