Assume a financial customer purchases several Huawei scale-out storage devices for service deployment.

Huawei scale-out storage, like OceanStor Pacific, uses multiple network planes. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* states:

- Option A: True. “The internal management network handles communication for deployment, upgrades, resource configuration, alarms, and certificate updates.”

- Option B: False. “In DPC scenarios, the back-end storage network is used for internal communication between storage nodes and OSDs, not for DPC-to-OSD data transfer, which occurs over the service network.”

- Option C: True. “The management network connects to the customer’s management infrastructure for system administration.”

- Option D: True. “The service network interfaces with applications via S3, HDFS, NFS, CIFS, and POSIX.”

Thus, option B is false.
