The following single-choice descriptions that do not belong to the features of the horizontally extended file storage function are:
Correct Answer: A
Question 97
Assume a government customer purchased several Huawei scale-out storage devices for service deployment. An engineer needs to configure file services in standard protocol scenarios. Which of the following actions does not need to be performed by the engineer during the configuration?
Correct Answer: A
Configuring file services in Huawei scale-out storage systems, such as OceanStor Pacific, involves specific steps for standard protocols like NFS or CIFS. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* states: "To configure file services, the engineer must create a converged storage pool to allocate resources, create namespaces for organizing file systems, and enable file services on the relevant nodes. The Distributed Parallel Client (DPC) is optional and used for high- performance parallel file access, not a requirement for standard protocol scenarios." Let's evaluate: - Option A: Not required. DPC is not mandatory for standard file service protocols. - Option B: Required. A converged storage pool is needed to provide storage capacity. - Option C: Required. Namespaces organize file service resources. - Option D: Required. Enabling file services on nodes activates the protocols. Thus, option A is the action not needed.

Question 98
During the use of Huawei flash storage, an engineer wants to calculate the valid write bandwidth of disks. Which of the following formulas can calculate disk valid write bandwidth?
Correct Answer: C
The valid write bandwidth calculation for Huawei flash storage accounts for data disks in a RAID configuration. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* explains: "The valid write bandwidth of disks is calculated as the write bandwidth of a single disk multiplied by the number of disks, adjusted by the ratio of data disks to total disks to account for RAID overhead (e.g., parity disks). The formula is: Valid write bandwidth = Write bandwidth of a single disk × Number of disks × (Number of data disks / Total number of disks)." Let's evaluate: - Option A: Incorrect. This formula is for read bandwidth and uses system disks, not data disks. - Option B: Incorrect. It does not account for RAID overhead, which reduces effective bandwidth. - Option C: Correct. Matches the documented formula for valid write bandwidth. - Option D: Incorrect. Port bandwidth is unrelated to disk write bandwidth calculations. Thus, option C is correct.

Question 99
Which one of the following descriptions about the unified namespace is incorrect?
Correct Answer: A
Question 100
The IntoTier feature is also called automatic hierarchical storage, which stores files on storage devices with the same performance according to file attributes, and Realize the automatic migration of files between storage devices.
