Câu 2: H13-624-V5-5: HCIP-Storage V5.5

The deduplication and compression features of Huawei converged storage systems are widely used in actual production scenarios, especially in virtual desktop infrastructure (VDI) and database scenarios. Which of the following statements is false about data deduplication and compression?

1. A. In the adaptive deduplication and compression process, if the system detects that the fingerprints are different of the bytes are different after byte-by-byte comparison, the system compresses the data blocks. — đáp án hiện tại
2. B. During inline deduplication, the system checks whether the fingerprint exists in the fingerprint library. If yes, the system determines that the block is an old block.
3. C. During similarity-based deduplication in the background, the background analyzes the similarity-based deduplication opportunity table and performs similarity-based deduplication on data blocks with the same Similar Fingerprint (SFP).
4. D. Backup storage supports deduplication and compression of file systems. For LUNs, only deduplication is supported.
