Huawei H13-624_V5.5 Practice Exam Questions & Answers

Huawei scale-out storage, like OceanStor Pacific, uses multiple network planes. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* states:

- Option A: True. ''The internal management network handles communication for deployment, upgrades, resource configuration, alarms, and certificate updates.''

- Option B: False. ''In DPC scenarios, the back-end storage network is used for internal communication between storage nodes and OSDs, not for DPC-to-OSD data transfer, which occurs over the service network.''

- Option C: True. ''The management network connects to the customer's management infrastructure for system administration.''

- Option D: True. ''The service network interfaces with applications via S3, HDFS, NFS, CIFS, and POSIX.''

Thus, option B is false.

The valid write bandwidth calculation for Huawei flash storage accounts for data disks in a RAID configuration. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* explains: ''The valid write bandwidth of disks is calculated as the write bandwidth of a single disk multiplied by the number of disks, adjusted by the ratio of data disks to total disks to account for RAID overhead (e.g., parity disks). The formula is: Valid write bandwidth = Write bandwidth of a single disk Number of disks (Number of data disks / Total number of disks).'' Let's evaluate:

- Option A: Incorrect. This formula is for read bandwidth and uses system disks, not data disks.

- Option B: Incorrect. It does not account for RAID overhead, which reduces effective bandwidth.

- Option C: Correct. Matches the documented formula for valid write bandwidth.

- Option D: Incorrect. Port bandwidth is unrelated to disk write bandwidth calculations.

Thus, option C is correct.

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.

Option A is correct.Huawei's CLI guide for HyperCDP states that tocreate a HyperCDP schedule, the command used iscreate hyper_cdp_schedule general. Huawei explicitly notes that when creating a file system HyperCDP schedule, you set the type to file in this command.

Option B is incorrect.add hyper_cdp_schedule fsis used toadd a file system to an existing HyperCDP schedule, not to create the schedule itself.

Option C is incorrect.create fs_hyper_cdp generalis used tocreate HyperCDP for a file system, not to create the schedule object itself. The question specifically asks for the command to create aHyperCDP schedule.

Option D is incorrect.change hyper_cdp_schedule enabledis a modification/enabling-related command, not a creation command. Huawei's command reference separatescreateandchangeoperations for HyperCDP schedules.

This question addresses the behavior of remote replication consistency groups in Huawei storage systems, such as OceanStor Dorado or Pacific series. According to the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*, a consistency group ensures that multiple remote replication tasks operate as a single unit to maintain data consistency across LUNs or volumes. The material states: ''In a remote replication consistency group, if one replication task fails (e.g., due to a link failure or configuration issue), the entire consistency group is affected, and other tasks do not continue running normally. The system suspends all tasks in the group to preserve data consistency until the faulty task is resolved or manually split.'' This ensures that dependent data sets remain synchronized. Therefore, the statement that other tasks run normally without waiting for the faulty task is false, as the consistency group halts all tasks to maintain integrity.
