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

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 *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* outlines troubleshooting principles: “Basic troubleshooting principles include prioritizing high-severity alarms, analyzing external factors (e.g., network or host issues) before internal storage issues, and addressing network alarms before network element (NE) alarms to rule out connectivity issues.” Let’s evaluate:

- Option A: Correct principle. Network alarms are analyzed first to exclude external connectivity issues.

- Option B: Not a principle. The material does not prioritize general alarms over specific ones; it focuses on severity and context.

- Option C: Correct principle. Higher-severity alarms are addressed first to mitigate critical issues.

- Option D: Correct principle. External factors are checked before internal storage issues.

Thus, option B is not a basic troubleshooting principle.

This statement is true. Huawei’s HyperClone documentation states that reverse synchronization is supported only when the secondary LUN capacity is greater than or equal to the primary LUN capacity. In this question, the secondary LUN is 20 GB and the primary LUN is 10 GB, so the capacity condition for reverse synchronization is met.

Huawei also states that during reverse synchronization, the capacity of the primary LUN cannot be expanded. This directly matches the second part of the statement.
