An administrator notes that after a recent power outage, some open files were corrupted on one affected file server. Which of the following items should the administrator consider to determine the cau

Server memory (RAM) is volatile and its contents are lost upon power outage, but it doesn't cause corruption of files stored on disk; corruption would arise from data that was supposed to be written to disk but wasn't.

A faulty or depleted RAID controller battery prevents the write cache from flushing data to disks during a power outage, leading to loss of data in transit and potential corruption of open files that were not yet committed to stable storage.

A server's processor issues typically manifest as performance problems or system crashes, not specific file corruption directly attributable to a power outage on disk subsystems.

NIC teaming configuration relates to network redundancy and bandwidth, and has no direct impact on data integrity or persistence during a power loss event.
