A remote technician is notified that a LED light for a server's hard drive is red. Which of the following should the technician check to verify RAID functionality?

Network-based hardware administration is used for remote server management tasks such as power cycling or monitoring, and does not verify RAID array health or functionality.

Access control lists govern user and system permissions on network resources and have no diagnostic relationship to RAID arrays or storage health.

A file system check (such as fsck or chkdsk) inspects the file system structure and underlying storage integrity, surfacing RAID degradation or failure conditions that a red drive LED may indicate. It directly tests whether the RAID array is reading and writing data correctly. The other available options do not provide any mechanism to assess RAID functionality.

A serial cable provides direct out-of-band console access for configuration purposes but offers no built-in method to verify RAID array status or integrity.
