Huawei H13-624_V5.5 - HCIP-Storage V5.5

Option A is correct. Huawei’s CLI guide for HyperCDP states that to create a HyperCDP schedule , the command used is create 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 fs is used to add a file system to an existing HyperCDP schedule , not to create the schedule itself.

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

Option D is incorrect. change hyper_cdp_schedule enabled is a modification/enabling-related command, not a creation command. Huawei’s command reference separates create and change operations for HyperCDP schedules.

The SmartMigration feature in Huawei OceanStor Pacific enables data migration between storage resources. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* explains: “The split mode and migration rate of a SmartMigration task can be modified only when the task is in certain stat uses, such as Interrupted, Paused, or Faulty. When the task is in the Migrating status, changes to split mode or migration rate are not allowed, as the system is actively transferring data.” This is because modifying parameters during active migration could disrupt the process or cause data inconsistency. Let’s evaluate:

- Option A: Interrupted allows changes, as the task is stopped.

- Option B: Paused allows changes, as the task is temporarily halted.

- Option C: Faulty allows changes, as the task is not actively running.

- Option D: Migrating does not allow changes, as the task is in progress.

Thus, option D is the status that prevents changes.

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.

This question addresses the behavior of remote replication during a primary/secondary switchover in Huawei flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* explains: “During a primary/secondary switchover in remote replication, the secondary site becomes the primary site and starts accepting write I/Os. The original primary site, if available, becomes the secondary site. Data changes are tracked incrementally, but full synchronization does not occur automatically after the switchover unless explicitly configured or triggered by a fault recovery process.” The question’s statement that “all data will be synchronized” implies an automatic full synchronization, which is not the default behavior. Instead, only incremental changes are synchronized when replication resumes, making the statement false.
