H13-624_V5.5 Exam Dumps : HCIP-Storage V5.5

SPC (Storage Performance Council) benchmarks are discussed in the *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: “SPC-1 tests random I/O workloads, such as OLTP, database, and email scenarios, while SPC-2 tests sequential large I/O access, such as video streaming or backups.” Let’s evaluate:

- Option A: Incorrect. SPC-2 is for sequential large I/Os, not random small I/Os (which is SPC-1).

- Option B: Incorrect. SPC-1 is for random I/Os, not sequential large I/Os.

- Option C: Correct. SPC-2 is designed for sequential large I/O access scenarios.

- Option D: Incorrect. SPC-1, not SPC-2, tests OLTP, database, and email scenarios.

Thus, option C is true.

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.
