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

The software installation process for Huawei OceanStor Pacific scale-out storage systems is detailed in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let’s evaluate each option:

- Option A: True. The material states: “For block service installation with converged compute and storage nodes, each node requires at least 20 vCPUs to support management and data processing tasks.”

- Option B: True. The material confirms: “In converged deployments, the disk quantity difference between any two nodes in a storage pool must not exceed 2 or 30% of the disk count on the node with the most disks to ensure balanced performance.”

- Option C: False. The material explains: “Wizard-based software installation automates node addition, network configuration, and control cluster creation via DeviceManager, reducing manual steps. Engineers do not need to perform these tasks manually before installing the OceanStor Pacific software.” This makes the statement incorrect.

- Option D: True. The material notes: “DPC installation requires a minimum of 20 GB of memory on compute nodes to ensure stable operation.”

Thus, option C is false.

The HyperCDP (Continuous Data Protection) feature in Huawei all-flash storage, like OceanStor Dorado, provides high-frequency snapshots. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states:

- Option A: True. “HyperCDP snapshots can be used for data analysis, application testing, and backup, as they provide consistent point-in-time copies.”

- Option B: True. “After a HyperCDP snapshot is created, write requests to the source LUN use copy-on-write (COW) technology, storing new data in a new storage pool location and updating the source LUN’s pointer.”

- Option C: False. The material clarifies: “HyperCDP snapshots can be directly mapped to hosts as read-only LUNs, without requiring file system sharing, for accessing point-in-time data.”

- Option D: False. “HyperCDP is optimized for high-density snapshots with low memory overhead, using metadata structures rather than full file system objects.”

Thus, options A and B are true.

Disk replacement in Huawei OceanStor Pacific 9950 is covered in the *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: “SmartKit guides disk replacement, requiring engineers to complete pre-processing steps, such as isolating the faulty disk and verifying redundancy, before proceeding with removal and installation.” Let’s evaluate:

- Option A: Incorrect. The material does not specify a 60-second wait after disconnecting the disk; it emphasizes immediate removal after pre-processing.

- Option B: Correct. The material confirms that SmartKit prompts for pre-processing (e.g., disabling the disk) before replacement.

- Option C: Incorrect. There is no 10-minute limit for heat dissipation concerns; the focus is on quick replacement to minimize reconstruction time.

- Option D: Incorrect. No specific 10-second interval is required to prevent disk damage; the material advises prompt insertion after removal.

Thus, option B is true.
