The question addresses the configuration process for storage pools in Huawei OceanStor Dorado 18000 series systems. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* clarifies: “To create storage pools, an engineer configures the physical disks or disk domains, which serve as the foundation for storage resources. LUNs and LUN groups are created after the storage pool is established, as LUNs are logical divisions of the pool’s capacity. Mapping LUN groups to host groups is a subsequent step to enable host access.” The statement in the question incorrectly suggests that LUNs, LUN groups, and mappings must be configured before creating storage pools, which reverses the actual process. Storage pools are a prerequisite for LUN creation, not the other way around, making the statement false.

The SmartEncryption feature in Huawei OceanStor Pacific ensures data security. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* explains:

- Option A: True. “For DPC or NFS reads, self-encrypting disks (SEDs) retrieve authentication keys from the key management server, decrypt ciphertext, and return plaintext to the protocol layer.”

- Option B: True. “SmartEncryption supports encrypted writes and decrypted reads via NFS, CIFS, HDFS, and S3 protocols.”

- Option C: False. “SmartEncryption encrypts data at the storage layer. Clients using NFS, CIFS, or DPC write data that is automatically encrypted by the system before storage, not written as plaintext.”

- Option D: True. “OceanStor Pacific uses SEDs for disk-level encryption, ensuring all service data is encrypted.”

Thus, option C is false.
