Question 4
In the HyperMetro active-active data center solution, data centers A and B are deployed. If the storage array in data center A fails, which of the following statements are true? (Multiple Choice)
A. UltraPath automatically disables all paths to data center A and forwards all I/Os to data center B.
B. The storage array in data center B uses a differential bitmap to record newly received I/Os.
C. After the storage array in data center A is recovered, the active-active relationship is automatically restored. Based on the differential bitmap, incremental data is automatically synchronized without affecting upper-layer applications.
D. If the storage array in data center A takes the initiative to power off, a command is sent to the storage array in data center B, asking the storage array to take over services.

Question 5
Which is the correct formula for calculating the file system backup bandwidth?
A. If replication is not required, the formula is as follows: Required bandwidth (without deduplication) = Data amount of full backup -f Backup window -r Bandwidth utilization rate.
B. If replication is required, the formula is as follows: Required bandwidth (with deduplication) = Amount of data to be replicated -r Backup window -r Bandwidth utilization rate.
C. If replication is not required, the formula is as follows: Required bandwidth (with deduplication at the media end) = Data amount of full backup -r Deduplication ratio -r Backup window -f Bandwidth utilization rate.
D. If replication is not required, the formula is as follows: Required bandwidth (with client deduplication) = Data amount of full backup -=- Backup window -f Bandwidth utilization rate.
