A company has purchased multiple Huawei OceanStor Pacific series devices to deploy the remote replication...

A is true. Huawei’s replication-cluster management documentation states that for capacity reduction, the number of nodes to be removed from a replication cluster must be greater than or equal to 4 . This matches the intent of the statement.

B is false. Huawei provides a Change Name operation for replication clusters, which shows that the replication cluster name can be changed . Therefore, the statement saying the name cannot be changed is incorrect.

C is false. Huawei states that the replication network cannot use the same subnet as other networks , and the replication network also does not share network ports with other networks . Therefore, saying it can share the same subnet is incorrect.

D is true. Huawei’s documentation for changing a replication cluster IP address states that when different replication ports on the same node use IP addresses in the same network segment , the original policy-based route must be deleted before a new policy-based route is configured .
