Which two commands never trigger an implicit rebalancing within the disk group?. (Choose two.)
Correct Answer: A,C
Explanation/Reference: Explanation: Altering Disk Groups You can use the ALTER DISKGROUP SQL statement to alter a disk group configuration. You can add, resize, or drop disks while the database remains online. Whenever possible, multiple operations in a single ALTER DISKGROUP statement are recommended. Grouping operations in a single ALTER DISKGROUP statement can reduce rebalancing operations. Oracle ASM automatically rebalances when the configuration of a disk group changes. By default, the ALTER DISKGROUP statement does not wait until the operation is complete before returning. Query the V$ASM_OPERATION view to monitor the status of this operation. add_disk_clause Use this clause to add one or more disks to the disk group and specify attributes for the newly added disk. Oracle ASM automatically rebalances the disk group as part of this operation. drop_disk_clause Use this clause to drop one or more disks from the disk group. DROP DISK The DROP DISK clause lets you drop one or more disks from the disk group and automatically rebalance the disk group. When you drop a disk, Oracle ASM relocates all the data from the disk and clears the disk header so that it no longer is part of the disk group. The disk header is not cleared if you specify the FORCE keyword.
