Question 651 - H13-624 discussion
After testing, the bandwidth of the two data centers of the customer is 155Mbit/s, the peak write bandwidth of an application is 9.8MB/s, and the average The write bandwidth is 300KB/s, the average write I/O size is 4KB., and the bandwidth utilization rate is 70%. Colleagues choose active and standby synchronous remote replication for disaster recovery Scheme, the scheme:
A.
Not feasible, 200Mbit/s is required to calculate the bandwidth.
B.
Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the bandwidth utilization rate must be >80%.
C.
Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the write I/O size must be less than 2KB.
D.
Feasible, because the conditions meet the requirements of the primary and standby synchronous remote replication disaster recovery program.
