What is the default AU size of an ASM disk group？ What is the maximum AU size in an ASM disk group？（）

A. The ASM rebalance operation will likely consume fewer resources and complete in a shorter amount of time.
B. The ASM rebalance operation will consume fewer resources and complete in a longer amount of time.
C. The ASM rebalance operation will be parallelized and should complete in a shorter amount of time.
D. There is no ASM_POWER_LIMIT setting used in ASM.
E. None of the above.

A. Failed disks are taken offline immediately but are not dropped.
B. Disk data is never lost.
C. By default， the failed disk is not dropped from the disk group ever， protecting you from loss of that disk.
D. The failed disk is automatically reformatted and then resynchronized to speed up the recovery process.
E. Hot spare disks are automatically configured and added to the disk group.

A. SGA
B. Database processes
C. Database datafiles
D. Control files
