H13-624_V5.5 Exam Dumps : HCIP-Storage V5.5

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* confirms: “The CLI command ‘show license_active’ is used to query details of activated licenses on Huawei flash storage systems, including license status and features enabled.” This makes the statement true, as the command is a standard tool for license management.

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 HyperSnap feature in Huawei flash storage systems, such as OceanStor Dorado, enables point-in-time snapshots for data protection. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states: “To create snapshots using HyperSnap, the storage pool containing the source LUNs must have sufficient available capacity to store snapshot metadata and copy-on-write (COW) data. If the storage pool lacks free space, snapshot creation for a protection group will fail.” This aligns with the question’s statement that a lack of available capacity in the storage pool prevents snapshot creation for a protection group, making the statement true. The material emphasizes that capacity issues are a common cause of snapshot failures, as snapshots require additional space for incremental changes.
