Oracle 11G OCP 1Z0-053 50

（50）Examine the following command:

ALTER DISKGROUP data MOUNT FORCE;

In which scenario can you use the above command to mount the disk group?

A. when ASM disk goes offline

B. when one or more ASM files are dropped

C. when some disks in a disk group are offline

D. when some disks in a failure group for a disk group are rebalancing

答案：（C）

解析：

《Automatic Storage Management Administrator's Guide》 4.10.1

Oracle ASM對於ALTER DISKGROUP命令提供了MOUNT FORCE選項,在正常或high redundancy模式下，

甚至在磁碟組的有些磁碟不可用的情況下, 來mount ASM磁碟組.

沒有MOUNT FORCE選項,如果磁碟組具有損壞或丟失的磁碟,mount磁碟組會失敗.
