You must replace a failed disk that was dropped from a disk group.
You want the rebalance operation to occur with minimal performance impact.
Which two options exist to achieve this? (Choose two.)
A.
Make sure that the ASM_POWER_LIMIT parameter is set to 1 before rebalancing the disk group.
B.
Increase the value of the DISK_REPAIR_TIME attribute for the disk group.
C.
Use the WAIT clause with the ALTER DISKGROUP command.
D.
Decrease the value of the DISK_REPAIR_TIME attribute for the disk group.
E.
Set the POWER clause to 1 in the ALTER DISKGROUP command.
Correct: A,E
(A=E) The value you specify in the POWER clause defaults to the value of the ASM_POWER_LIMIT initialization parameter.
Wrong C: WAIT allow a script that adds or removes disks to wait for the disk group to be rebalanced before returning control to the user. You can explicitly terminate a rebalance operation running in WAIT mode, although doing so does not undo any completed disk add or drop operation in the same statement. https://docs.oracle.com/cd/B19306_01/server.102/b14200/statements_1006.htm
Wrong B,D: The DISK_REPAIR_TIME disk group attribute specifies how long a disk remains offline before Oracle ASM drops the disk. If a disk is made available before the DISK_REPAIR_TIME parameter has expired, the storage administrator can issue the ONLINE DISK

Correct: A, E
