Huawei Certified ICT Professional – Storage v5.5 (HCIP-Storage) — Question 6

A financial customer has purchased two OceanStor Dorado 18000 series storage devices for service deployment. To ensure service data reliability, an engineer configures the HyperSnap feature on the storage devices. Which of the following commands can the engineer use to change the snapshot rollback rate on the command line interface (CLI)?

Answer options

• A. change snapshot speed
• B. change snapshot flowctrl
• C. show qos snapshot_flowctrl_lun
• D. change snapshot deactivate

Correct answer: B

Explanation

The correct command to adjust the snapshot rollback rate is 'change snapshot flowctrl', as it directly modifies the flow control settings for snapshots. The other options either do not pertain to changing the rollback rate or are incorrect commands that do not exist in the CLI context for this operation.
