Which two recommendations should you make to speed up the rebalance operation if this type of failure happens again?

You administer an online transaction processing (OLTP) system whose database is stored
in Automatic Storage Management (ASM) and whose disk group use normal redundancy.
One of the ASM disks goes offline, and is then dropped because it was not brought online
before DISK_REPAIR_TIME elapsed. When the disk is replaced and added back to the disk
group, the ensuing rebalance operation is too slow. Which two recommendations should
you make to speed up the rebalance operation if this type of failure happens again?

A.
Increase the number of DBWR_IO_SLAVES in the ASM instance.

B.
Increase the value of the ASM_POWER_LIMIT parameter.

C.
Set the DISK_REPAIR_TIME disk attribute to a lower value.

D.
Specify the statement that adds the disk back to the disk group.

E.
Increase the number of ASMB processes.
