Huawei H13-624_V5.5 Exam With Confidence Using Practice Dumps

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.

The HyperMetro feature in Huawei storage systems, such as OceanStor Dorado, provides active-active data access with arbitration mechanisms to handle site failures. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* details HyperMetro arbitration modes:

- Option A: True. The material states: “In the absence of a quorum server, HyperMetro operates in static priority mode, where the preferred site is designated to win arbitration and continue services during a failure.”

- Option B: True. The material explains: “In static priority mode, if the preferred site fails, the non-preferred site does not automatically take over to avoid split-brain scenarios. Services stop, and manual intervention is required to forcibly start services on the non-preferred site.”

- Option C: False. The material clarifies: “In quorum server mode, the quorum server can be deployed on physical machines or virtual machines, provided it meets the performance and network requirements.” This makes the statement that it can only be deployed on physical machines incorrect.

- Option D: True. The material confirms: “In quorum server mode, if the link between storage systems fails, both systems send arbitration requests to the quorum server to determine which site continues providing services.”

Thus, option C is false.
