What are the advantages of variable extent size support for large ASM files?（）
A
It improves resync operations when the disk comes online after being taken offline for maintenance purposes.
B
It improves performance in the extended cluster configuration by reading from a local copy of an extent.
C
Fewer extent pointers are needed to describe the file and less memory is required to manage the extent maps in the shared pool.
D
This feature enables faster file opens because of the reduction in the amount of memory that is required to store file extents.
