考题 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 COMPATIBLE.ASM attribute is set to 11.1.Which two statements are true in this scenario for the features enabled for ASM? ()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.
