The correct answer is D. It is feasible because the conditions meet the requirements of the master-slave synchronous. See the full explanation below for the reasoning.
Question
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, the average write bandwidth is 300KB/s, the average write I/O size is 4KB, and the bandwidth utilization rate is 70%, my colleague chooses the active- standby synchronous remote replication disaster recovery solution, the solution:
Options
- ANot feasible, the calculated bandwidth requires 200Mbit/s.
- BNot feasible, the master-slave synchronous remote replication disaster recovery solution requires
- CNot feasible, the active-standby synchronous remote replication disaster recovery solution
- DIt is feasible because the conditions meet the requirements of the master-slave synchronous
