A company purchases two sets of Huawei's scale-out file storage, which are deployed in the production data center and the disaster recovery data center respectively. The storage administrator needs to create a replication zone channel between the two storage systems. Which of the following option descriptions is correct?

The bandwidth of the two data centers tested by the customer is 155Mbit/s, the peak write bandwidth of an application is 9.8MB/s, the average written bandwidth is 300KB/s, the average write I/O size is 4KB, and the bandwidth utilization rate is 70%. Colleagues choose the primary and standby synchronous remote replication disaster recovery solution

Colleagues customized Huawei's primary and backup disaster recovery solution for the customer. The customer already has a set of OceanStor 2600TV2 and a third-party storage system. The two sets of equipment are placed in two data centers to implement the primary and backup disaster recovery. The solution is?

Suppose that you allocate 20 GB to a thin LUN, write 30 GB to the LUN, and then delete 25 GB data from it.
How large is the thin LUN now?

When planning the back-end storage network IP address of the OceanStor 9000 IB networking deployment plan, you need to plan 2 back-end storage IP addresses and 1 temporary IP address for each node.
