Free Huawei H13-624_V5.5 Practice Exam with Questions & Answers | Set: 2

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* describes the tools used for Huawei storage system deployment: “The Storage Deployment Tool (SDT) is designed to streamline software installation for Huawei storage systems. SDT collects and evaluates compatibility information in a one-stop manner and supports batch installation of UltraPath, the multipathing software, enhancing installation efficiency.” The SDT automates and simplifies deployment tasks, making it the correct tool for this description.

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.

The question focuses on the running statuses of remote replication pairs in Huawei’s flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* details the remote replication feature and its statuses. The material states: “When the pair running status is ‘Normal,’ the remote replication pair is fully synchronized, meaning data between the primary and secondary LUNs is consistent, and synchronization is complete.” This matches option C.

- Option A: Incorrect. The training material indicates that if a pair is deleted from one site, causing inconsistency, the status may not necessarily change to “To be recovered.” Instead, it may require manual intervention or reconfiguration, and “To be recovered” is typically associated with link failures or incomplete synchronization, not deletion.

- Option B: Incorrect. The “Split” status occurs when the pair relationship is interrupted, but it can be due to manual intervention or automatic triggers (e.g., link failure). The parenthetical “not manually” is misleading, as the material does not restrict “Split” to non-manual causes.

- Option D: Incorrect. The “To be synchronized” status indicates that the pair is preparing for synchronization but is not yet consistent. There is no requirement to manually disconnect the pair for single LUN service needs, as the system can operate with the primary LUN independently during this state.

Thus, option C is the only accurate statement based on official documentation.

This question tests knowledge of the Huawei OceanStor Dorado series architecture, as covered in the *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)*. Let’s evaluate each option:

- Option A: True. The material confirms: “The back-end shared interface module of OceanStor Dorado 18000 is inserted into the enclosure, allowing simultaneous access to disk enclosures by all controllers in the engine.”

- Option B: True. The material states: “Dorado V6 series and converged storage products adopt the PCIe Scale-Out architecture for high-performance interconnects.”

- Option C: False. The material specifies: “OceanStor Dorado 18000 uses 100 Gbit/s RDMA shared interface modules for cross-engine expansion, supporting full interconnection between 8, 12, and 16 controllers.” The claim of 200 Gbit/s RDMA is incorrect, as 100 Gbit/s is the standard for Dorado 18000.

- Option D: True. The material notes: “OceanStor Dorado 18000 supports up to 28 interface modules and uses a 100 Gbit/s RDMA network for intra-engine mirroring and cross-engine interconnection.”

Thus, option C is false due to the incorrect RDMA speed.
