An Application's Peak Write Throughput Is 10 MB/s, Average Write

Multiple Choice

An application's peak write throughput is 10 MB/s, average write throughput is 280 KB/s, average write I/O size is 4 KB, and the network bandwidth utilization rate is 70%. If OceanStor V3 storage systems are used to implement data disaster recovery based on asynchronous replication, Synchronization Method is set to Timed wait when synchronization begins, and the value of Interval is 4 hours, the expected duration to synchronize data is no more than 1 hour. So the minimum network throughput should be (_) .

A) 1600 KB/s
B) 400 KB/s,
C) 15 MB/s
D) 10 MB/s
