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

This question addresses issues with enabling object services in Huawei OceanStor Pacific 9550 systems, as covered in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. The material outlines prerequisites for enabling object services, including time synchronization. Let’s evaluate:

- Option A: Possible cause. The material states: “Manual time adjustments on cluster nodes can cause inconsistencies in conflict handling, preventing object services from being enabled.”

- Option B: Possible cause. The material notes: “Lack of NTP synchronization or use of different NTP sources can lead to time discrepancies, causing object service failures.”

- Option C: Not a cause. The material clarifies: “Namespaces with the same name under the same account are allowed in OceanStor Pacific, as they are managed uniquely per tenant or bucket.” This does not prevent object service enablement.

- Option D: Possible cause. The material confirms: “Inconsistent NTP clocks between the storage cluster and client can disrupt object service operations, as time synchronization is critical for protocols like S3.”

Thus, option C is not a possible cause.

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.

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.
