Huawei Updated H13-624_V5.5 Exam Questions and Answers by neriah

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses performance issue demarcation: “If the latency on the compute side is significantly higher than on the storage side, the issue is likely outside the storage system, such as in the host, network, or application layer. If the storage side showed high latency (e.g., due to disk performance limits), it would be reflected in the STORAGE metrics.” The statement incorrectly attributes the issue to the storage system, as higher compute-side latency points to external factors, making it 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.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* details the low-level design (LLD) mode for Huawei scale-out storage: “In LLD mode, the Storage Deployment Tool (SDT) is used to plan nodes, networks, and clusters, generating a configuration file that guides subsequent installation and deployment.” The SDT ensures precise configuration for complex deployments, making it the correct tool for this task.
