Huawei H13-624_V5.5 Exam With Confidence Using Practice Dumps

This question tests knowledge of the reliability features of the Huawei OceanStor Pacific series, as covered in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let’s evaluate each option:

- Option A: False. The training material states: “OceanStor Pacific uses advanced erasure coding (EC) and multi-copy technologies for data reliability, moving beyond traditional disk-level RAID modes.” While RAID-like concepts may be used internally, the system primarily relies on distributed EC or replication, not traditional RAID, making this statement inaccurate.

- Option B: True. The material confirms: “Kunpeng processors integrate multiple chip functions, reducing points of failure and enhancing hardware reliability.” This is a correct statement.

- Option C: True. The material notes: “Link aggregation ensures transmission link redundancy, with automatic switchover or isolation for faulty or subhealthy links, maintaining service continuity.” This is accurate.

- Option D: False. The material clarifies: “Multi-copy technology ensures data redundancy across nodes, but it does not implement intra-node RAID. If a node fails, reliability depends on inter-node copies or EC, and it is not necessarily higher than EC mechanisms, which are optimized for distributed systems.” This makes the statement false, as it misrepresents the technology and its comparative reliability.

Thus, options A and D are false.

Option C is false. Huawei’s CSI documentation states that the CSI Controller runs independently in a Pod in Deployment mode , not StatefulSet mode . Huawei also says it is used to interact with storage and create/delete resources on the storage side. So the incorrect part is the StatefulSet mode description.

Option A is true. Huawei explains that Kubernetes sidecar components register and monitor Kubernetes objects and invoke the CSI Driver when needed , and the Huawei CSI Driver implements those calls on Huawei storage.

Option B is true. Huawei states that Huawei storage communicates with the Huawei CSI plug-in through RESTful to provide NAS/SAN storage resource services .

Option D is true. Huawei states that the CSI Node component is deployed in DaemonSet mode on all worker nodes and is used for node-side operations such as mounting and unmounting storage resources.
