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

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.

This question addresses issues with enabling object services in Huawei OceanStor Pacific 9550 systems, as covered in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. The material outlines prerequisites for enabling object services, including time synchronization. Let’s evaluate:

- Option A: Possible cause. The material states: “Manual time adjustments on cluster nodes can cause inconsistencies in conflict handling, preventing object services from being enabled.”

- Option B: Possible cause. The material notes: “Lack of NTP synchronization or use of different NTP sources can lead to time discrepancies, causing object service failures.”

- Option C: Not a cause. The material clarifies: “Namespaces with the same name under the same account are allowed in OceanStor Pacific, as they are managed uniquely per tenant or bucket.” This does not prevent object service enablement.

- Option D: Possible cause. The material confirms: “Inconsistent NTP clocks between the storage cluster and client can disrupt object service operations, as time synchronization is critical for protocols like S3.”

Thus, option C is not a possible cause.

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.
