Which of the following best describes an HBA?

An HBA is a hardware adapter that connects a host to a storage area network to enable block-level I/O. It serves as the interface for storage traffic, presenting storage to the operating system as SCSI devices and handling Fibre Channel or iSCSI protocols. This description matches what an HBA does: it links the host to the SAN and enables block storage access. The other options describe a storage device, backup software, or a file-level network protocol, none of which capture the function of an HBA.
