The scale-out storage system supports cabinet-level security. That is, N data blocks and M parity blocks are stored in different cabinets. If M nodes or M disks are faulty, the system can still read and write data without service interruption or data loss. If M cabinets are faulty, services may be interrupted.
Correct Answer: A
The statement describes the reliability mechanism of Huawei's scale-out storage systems, such as the OceanStor Pacific series, which employ cabinet-level security to enhance data availability. According to the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*, scale-out storage systems use distributed architectures with N data blocks and M parity blocks stored across different cabinets to ensure redundancy. This design leverages erasure coding (EC) or similar mechanisms to tolerate faults. The material explicitly states: "In a scale-out storage system, N+M redundancy ensures that if up to M nodes or M disks fail, the system can reconstruct data withoutinterruption or loss. However, if M cabinets fail, the system may lose the ability to access sufficient parity or data blocks, potentially interrupting services." This confirms that the system can handle M node or disk failures without issue, but M cabinet failures may disrupt services due to the loss of distributed data or parity blocks. Therefore, the statement is true.

smarttier
H13-624_V5.5 Exam Question 28
Assume a bank customer purchased several Huawei flash storage devices for deploying the document Imaging service. This service mainly involves random large I/Os, more read operations than write operations, and many metadata operations, with obvious hot and cold data characteristics.
Correct Answer: B
H13-624_V5.5 Exam Question 29
The backup and archiving scenario mainly involves sequential read of large I/Os, where there are more read I/Os than write I/Os and hot data areas are obvious. The service characteristics of this scenario are the same as those of the database OLAP scenario.
Correct Answer: A
H13-624_V5.5 Exam Question 30
When delivering Huawei all-flash projects, Huawei engineers introduced the HyperCDP feature of flash storage to customers. Which of the following statements are true about this feature?
Correct Answer: A,B
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.
