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

SmartDedupe and SmartCompression are data reduction technologies in Huawei all-flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* provides details:

- Option A: True. The material states: “Post-process compression involves writing data to storage media first, then reading it back for compression during idle periods.”

- Option B: True. The material confirms: “Inline deduplication divides data into blocks and calculates fingerprints to identify duplicates before writing.”

- Option C: False. The material clarifies: “Similarity-based deduplication, whether inline or background, requires dividing data into blocks to calculate fingerprints for similarity detection. Direct calculation without block division is not supported.” This makes the statement incorrect.

- Option D: True. The material notes: “Backup storage supports deduplication and compression for file systems to optimize space usage.”

Thus, option C is false.

This question addresses the behavior of remote replication consistency groups in Huawei storage systems, such as OceanStor Dorado or Pacific series. According to the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*, a consistency group ensures that multiple remote replication tasks operate as a single unit to maintain data consistency across LUNs or volumes. The material states: “In a remote replication consistency group, if one replication task fails (e.g., due to a link failure or configuration issue), the entire consistency group is affected, and other tasks do not continue running normally. The system suspends all tasks in the group to preserve data consistency until the faulty task is resolved or manually split.” This ensures that dependent data sets remain synchronized. Therefore, the statement that other tasks run normally without waiting for the faulty task is false, as the consistency group halts all tasks to maintain integrity.
