Which of the Following Statements About Management Ports on C72

Which of the following statements about management ports on C72 nodes are correct? (Choose all that apply.)

A) When the OceanStor 9000 cluster contains only C72 nodes and the number of C72 nodes is not smaller than three, each controller module A of the first three nodes provides one NIC0 port as the management port.
B) When the C72 nodes and the non-C72 nodes are deployed together, you can select C72 nodes to provide independent management network ports.
C) When the C72 nodes and the non-C72 nodes are deployed together and applied to object storage service, only the node that provides independent management network ports can serve as an object storage management node.
D) When deploying a storage cluster, you need to separately assign an IP address to port NIC0 on the C72 node in the cluster.
