Question
You are managing an Oracle Database 11g ASM instance with a disk group dg01 having three disks. One of the disks in the disk group becomes unavailable because of power failure. You issued the following command to change the DISK_REPAIR_TIME attribute from 3.6 hours to 5 hours:
ALTER DISKGROUP dg01 SET ATTRIBUTE *disk_repair_time' = '5h'; To which disks in the disk group will the new value be applicable?

Explanation
Check out the answer options, it is tricky. The NOT OFFLINE disks equals ONLINE disks. Refer to Set the DISK_REPAIR_TIME Disk Group Attribute Appropriately. 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 command and Oracle ASM resynchronizes the stale data from the mirror side. In Oracle Database 11g, the online disk operation does not restart if there is a failure of the instance on which the disk is running. You must reissue the command manually to bring the disk online.
