（B）Use the crsct1 set log res "resource_name=debugging_level2" command.

（C）Set the environment variable _USR_ORA_DEBUG=1 and then stop and restart the resource that requires resource debugging data to be collected.

（D）Use the cluvfy comp command for the specific resource within a component.

（A）All ASM Disks belonging to a disk group should have the same hardware specifications and storage attributes for optimal performance.

（B）All ASM Disks belonging to a disk group should be of the same size for optimal performance.

（C）Data files, redo logs, and RMAN backup pieces must be stored in different ASM disk groups for optimal performance.
