H13-624_V5.5 Huawei HCIP-Storage V5.5 Free Practice Exam Questions (2026 Updated)

This statement is false . Huawei’s official OceanStor Dorado networking documentation states that quorum links must be established on GE, 10GE, or 25GE networks, but not on a Fibre Channel network . Therefore, it is incorrect to say that only 10GE can be used and that 25GE cannot be used .

Huawei’s SmartIO interface module documentation also explicitly states that 10 Gbit/s and 25 Gbit/s SmartIO interface modules can be used for HyperMetro quorum links . This directly confirms that 25GE is supported for quorum networking. Fibre Channel, however, is not supported for quorum links.

So the correct judgment is:

10GE → supported

25GE → supported

Fibre Channel → not supported

Hence, the overall statement is FALSE .

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses Oracle database troubleshooting: “To locate Oracle alert log files, commands like ‘show parameter background_dump_dest’ (SQL*Plus) and ‘CRS_HOME/bin/diagcollection.sh’ (Oracle Grid Infrastructure) can query or collect log paths. The ‘ioscan -funC disk’ command (HP-UX) lists disk devices, which may indirectly help identify storage paths.” However, “db2support outpath -d db_name -c” is specific to IBM DB2 databases, not Oracle, making it irrelevant for querying Oracle alert log paths. Thus, option D cannot be used.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* describes user roles in Huawei flash storage systems: “The administrator role is a built-in role with full privileges, including managing users, performing system upgrades, changing the system time, powering off the device, and restarting the device.” This role is designed for comprehensive system management, confirming that the statement is true.

The Distributed Parallel Client (DPC) in Huawei OceanStor Pacific systems enables parallel file access. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* explains: “When adding DPC nodes, engineers can manually add nodes using DeviceManager by entering the management IP address of the node, not the service IP address. The management IP is used to establish control plane communication for node integration.” The service IP address is used for data access by clients, not for node creation or management tasks. Therefore, the statement that the engineer can add a node using the service IP address is false.

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 statement describes the reliability mechanism of Huawei’s scale-out storage systems, such as the OceanStor Pacific series, which employ cabinet-level security to enhance data availability. According to the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*, scale-out storage systems use distributed architectures with N data blocks and M parity blocks stored across different cabinets to ensure redundancy. This design leverages erasure coding (EC) or similar mechanisms to tolerate faults. The material explicitly states: “In a scale-out storage system, N+M redundancy ensures that if up to M nodes or M disks fail, the system can reconstruct data without interruption or loss. However, if M cabinets fail, the system may lose the ability to access sufficient parity or data blocks, potentially interrupting services.” This confirms that the system can handle M node or disk failures without issue, but M cabinet failures may disrupt services due to the loss of distributed data or parity blocks. Therefore, the statement is true.

This statement is true . The available Huawei exam-reference source for this exact question marks the correct answer as TRUE , indicating that when link bandwidth is too low or concurrent processing capability is insufficient , the active-active service may become faulty , while the remote backup service is not affected .

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses host-side performance issues: “Outdated HBA drivers or insufficient concurrent HBAs can cause high host latency. Upgrading the HBA driver to the latest version ensures compatibility and performance. Adjusting the multipathing software’s load balancing algorithm to min-task optimizes I/O distribution across paths, reducing latency.” Let’s evaluate:

- Option A: Incorrect. HBA vendor software may query settings, but modifying concurrent HBAs is typically a firmware or driver-level task, not a standard management software function.

- Option B: Correct. Upgrading the HBA driver resolves compatibility and performance issues.

- Option C: Correct. The min-task algorithm balances I/O to minimize queuing delays.

- Option D: Incorrect. Cache prefetch policies affect storage-side performance, not host-side latency caused by HBA issues.

Thus, options B and C are the correct measures.

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.

The HyperSnap feature in Huawei flash storage systems, such as OceanStor Dorado, enables point-in-time snapshots for data protection. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states: “To create snapshots using HyperSnap, the storage pool containing the source LUNs must have sufficient available capacity to store snapshot metadata and copy-on-write (COW) data. If the storage pool lacks free space, snapshot creation for a protection group will fail.” This aligns with the question’s statement that a lack of available capacity in the storage pool prevents snapshot creation for a protection group, making the statement true. The material emphasizes that capacity issues are a common cause of snapshot failures, as snapshots require additional space for incremental changes.

This question tests knowledge of disk status indicators in Huawei OceanStor Pacific 9950 systems. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* provides details on disk module indicators: “A steady yellow location indicator on a main storage disk module indicates that the disk is faulty or about to fail. This status signals that the disk requires attention, such as replacement, to prevent data loss or service disruption.” The material further clarifies the following for other options:

- Option A: Incorrect. A blinking yellow indicator, not a steady one, typically indicates that the disk is being located (e.g., via DeviceManager or CLI).

- Option B: Incorrect. A steady green indicator signifies that the disk is running properly.

- Option C: Incorrect. A powered-off disk would have no indicator light or a specific power-off signal, not a steady yellow light.

Thus, option D accurately describes the disk’s status.

The software installation process for Huawei OceanStor Pacific scale-out storage systems is detailed in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let’s evaluate each option:

- Option A: True. The material states: “For block service installation with converged compute and storage nodes, each node requires at least 20 vCPUs to support management and data processing tasks.”

- Option B: True. The material confirms: “In converged deployments, the disk quantity difference between any two nodes in a storage pool must not exceed 2 or 30% of the disk count on the node with the most disks to ensure balanced performance.”

- Option C: False. The material explains: “Wizard-based software installation automates node addition, network configuration, and control cluster creation via DeviceManager, reducing manual steps. Engineers do not need to perform these tasks manually before installing the OceanStor Pacific software.” This makes the statement incorrect.

- Option D: True. The material notes: “DPC installation requires a minimum of 20 GB of memory on compute nodes to ensure stable operation.”

Thus, option C is false.

The SmartMigration feature in Huawei OceanStor Dorado enables seamless data migration between LUNs, as detailed in the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*. Let’s analyze each option:

- Option A: True. The material states: “SmartMigration between heterogeneous storage systems relies on SmartVirtualization to take over the source LUN, ensuring compatibility and seamless migration.”

- Option B: True. The material confirms: “The target LUN capacity must be greater than or equal to the source LUN capacity to accommodate all data during migration.”

- Option C: True. The material notes: “A LUN already mapped to an application server cannot be used as the target LUN for SmartMigration, as it would disrupt existing mappings.”

- Option D: False. The material explains: “The migration rate affects system resources. Setting the highest migration rate under heavy host service load can degrade performance due to resource contention. The rate should be adjusted based on load to minimize impact.” This makes the statement false, as high migration rates are not recommended during heavy loads.

Thus, option D is false.
