Which parameter should you specify to control the speed of the rebalancing activity?

You are maintaining the SALES database. You have added a new disk to a disk group. Automatic
Storage Management performs the rebalancing activity. You want to speed up the rebalancing
activity.
Which parameter should you specify to control the speed of the rebalancing activity?

A.
ASM_POWER_LIMIT

B.
ASM_DISKSTRING

C.
ASM_DISKGROUPS

D.
INSTANCE_TYPE

Explanation:
You should use the ASM_POWER_LIMIT parameter to control the speed of the rebalancing
activity. To ensure that rebalancing operations do not interfere with the ongoing user I/O, the
ASM_POWER_LIMIT parameter controls the speed of rebalancing operations. The value for the
ASM_POWER_LIMIT parameter ranges from 0 to 11. The default value of 1 indicates low
overhead. This is a dynamic parameter; therefore, you can set this to a low value during the day
and to a higher value overnight whenever a disk rebalancing operation must occur. You can also
control the speed of rebalancing by specifying a POWER clause in an ALTER DISKGROUP
statement or when rebalancing. The option stating that the ASM_DISKSTRING parameter is used
to control the speed of rebalancing is incorrect. The ASM_DISKSTRING parameter specifies one
or more strings, which are operating system dependent, to limit the disk devices that can be used
to create disk groups.
The option stating that the ASM_DISKGROUPS parameter is used to control the speed of
rebalancing is incorrect. The ASM_DISKGROUPS parameter specifies a list containing the names
of the disk groups that will be automatically mounted by the ASM instance at startup or by the
ALTER DISKGROUP ALL MOUNT; statement. The option stating that the INSTANCE_TYPE

parameter is used to control the speed of rebalancing is incorrect. The INSTANCE_TYPE
parameter identifies the instance as an ASM instance or non-ASM instance. For an ASM instance,
this parameter must be set to a value of ASM.
