A. The ASM compatibility attribute controls t he format of the disk group metadata.

D. The ASM compatibility attribute determines some of t he ASM features that may be used by the Oracle disk group.
E. The ADVM compatibility attribute determines the ACFS features that may be used by the Oracle 10g database.
Correct Answer: ABD
(解析:該題目的意思是一臺服務器上所有版本的所有數據庫都用 ASM,那么這里面就要求按照GI,只要 ASM 實例能夠兼容數據庫軟件,那么不同版本的數據庫都可以使用該 ASM。
答案 AD:disk group compatible.asm 屬性的值確定可以使用磁盤組的 Oracle ASM 實例的最低軟件版本。此設置還影響磁盤上 Oracle ASM 元數據的數據結構格式。
答案 B:disk group compatible.rdbms 屬性的值決定了任何數據庫的最小兼容數據庫初始化參數設置)
