644.View the Exhibit and examine the disk groups created at the time of migrating the database storage
to Automatic Storage Management (ASM).
Why does the FRA disk group initially have more free space even though both DATA and FRA disk groups
are provided with the same size?
A. Because the FRA disk group will not support dynamic rebalancing
B. Because the FRA disk group is not configured to support mirroring
C. Because disks in the FRA disk group are not formatted at this stage
D. Because the FRA disk group will support only a single size of allocation unit
Answer: B
答案解析：
此题没有图，故猜想FRA采用外部冗余，DATA采用normal redundancy (mirroring)。
因此选B。
