A government customer has purchased several Huawei OceanStor Pacific series storage devices.

This question addresses the process of adding DPC nodes in Huawei OceanStor Pacific systems. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* states: “To add DPC nodes, engineers can use DeviceManager to either manually add nodes by entering the management IP address or batch import nodes using a template. For manual addition, the management IP address is required to establish communication with the node. For batch import, a template must be downloaded, filled with node details, and uploaded to complete the process. Authentication is required in both modes to ensure secure node addition.” Let’s evaluate:

- Option A: False. Authentication is required for both manual and batch methods to validate node addition.

- Option B: True. The material confirms that the management IP address is required for manual node addition.

- Option C: False. The service IP address is not used for node addition; the management IP is needed.

- Option D: True. The material describes the batch import process as requiring a filled template upload.

Thus, options B and D are true.
