C. when one of the disks in a disk group is accidentally unplugged

D. when one or more file directory paths are accidentally deleted from an ASM disk group

E. when all the ASM disk groups for the ASM instance are lost

Answer: A,C,E

解析：元數(shù)據(jù)的用途是恢復(fù)磁盤(pán)組，如果磁盤(pán)組里面的磁盤(pán)出現(xiàn)損壞，應(yīng)該是物理的損壞則會(huì)導(dǎo)致該磁盤(pán)組無(wú)法工作，需要用到元數(shù)據(jù)恢復(fù)。如果是邏輯的從磁盤(pán)組中刪除磁盤(pán)，則不會(huì)到賬磁盤(pán)組無(wú)法工作，無(wú)需用到元數(shù)據(jù)，所以答案 D 是錯(cuò)誤的。
