282.You are managing an Oracle 11g database with ASM storage, for which the COMPATIBLE initialization parameter is set to 11.1.0. In the ASM instance, the COMPATIBLE.RDBMS attribute for the disk group is set to 10.2 and the COMPATIBLTME.ASM attribute is set to 11.1.

Which two statements are true in this scenario for the features enabled for ASM? (Choose two.)

A. The ASM-preferred mirror read feature is enabled.

B. The ASM supports variable sizes for extents of 1, 8, and 64 allocation units.

C. The ASM disk is dropped immediately from a disk group when it becomes unavailable.

D. The RDBMS always reads the primary copy of a mirrored extent of the ASM disk group.

Answer: AB

您用ASM存储管理Oracle 11g数据库,可COMPATIBLE初始化参数设置为11.1.0。在ASM实例中,用于磁盘组的COMPATIBLE.RDBMS属性设置为10.2,并且COMPATIBLE.ASM属性设置为11.1。
为ASM启用的特性,在此方案中哪两项描述是真实的?
A、ASM首选镜像读取功能被启用。
B、ASM支持用于1个、8个和64个分配单元的区的可变大小。
