Answers
Suggested answer: C

Explanation:

Controller enclosures in Huawei OceanStor series storage systems are equipped with battery backup units (BBUs) which provide backup power when the external power supply fails. This ensures that any data in the controller's cache can be synchronized to the disks in the disk enclosures before the power is cut. BBUs will be in a standby state when the power input is normal. If the BBUs become faulty, the service system will not be interrupted.
