The Administration Server of a domain falls due to a hardware failure. The hardware is beyond
repair.
Before the failure you prepared a “backup admin server”. You go through your planned recovery
process and are successful. The Administration Server is now running on different hardware. The
managed servers of the domain automatically reconnect to the admin server.
Select the two statements that are true.
A.
Files of deployed applications are available to the backup admin server from the same relative
location as they were to the original admin server.
B.
At the time of the failure ,the backup admin server was running in “Standby” mode on
differenthardware in the same network.
C.
When the admin server failed, you must have shut down and restarted the managed servers,
otherwise they could not have reconnected to the failed admin server.
D.
The backup admin server isany one of the running managed servers. You select one of the
managedservers, stop it, set its “administration” flag, andrestartitas the admin server of the
domain.
E.
The backup admin server must be running at the same DNS name or IP address as the
original.
Correct answer: B, E
A and E, application files must be available in the same relative location.
B and E.
for B: https://docs.oracle.com/cd/E50629_01/wls/WLACH/taskhelp/startstop/StartManagedServersInSTANDBY.html
E is the most possible option due to “The managed servers of the domain automatically reconnect to the admin server”

Can Admin Server be in STANDBY or just managed?
A & E
My vote is for A&E.
For B, if this is a correct answer, it implies that you have no way of recovering if you don’t have a standby admin server already running in standby mode. I do not believe this to be true.
B & E , Admin server can be started in Standby mode.
A & E :
Make your application files available to the new Administration Server by copying them from backups or by using a shared disk :
