Suggested answer: C

Explanation:

Before an XtremIO X1 cluster can start, it is required that the Battery Backup Units (BBUs) are charged to at least 70%. This ensures that there is sufficient power reserve to maintain data integrity and allow for safe shutdown procedures in case of an unexpected power loss. The BBUs provide power to the Storage Processors and other critical components during an outage, allowing them to complete any in-progress operations and commit data to SSDs1.

The startup process checks the BBU charge level and will only proceed if the minimum charge requirement is met. This is a safety feature designed to protect the system and the data it holds. If the BBUs are not adequately charged, the system will not start, preventing potential data loss or corruption that could occur if the system were to lose power without the ability to properly shut down1.
