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

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.

The cache write policy for Huawei scale-out storage, like OceanStor Pacific, is critical for performance-sensitive applications like video surveillance. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* states: “For video surveillance, which involves sequential large I/O writes, the write-back cache policy is recommended to maximize performance by buffering writes and reducing disk I/O latency. Write-through, which writes directly to disks, is less suitable due to higher latency.” The statement’s insistence on write-through for high-performance video surveillance is incorrect, as write-back is preferred, making the statement false.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* describes DME IQ: “DME IQ is a cloud-based management service that supports uploading performance logs and Disk Health Analysis (DHA) logs from Huawei flash storage. DHA logs include routine disk run data, such as health status and I/O statistics, used for predictive maintenance.” This confirms the statement is true.
