An administrator is upgrading the backup server from a single tape drive to a SCSI tape library. The library has been unpackaged, mounted, and the library drivers installed. Which of the following…

After mounting the library and installing its drivers, the missing physical link is the SCSI cable that runs between the tape library's SCSI port and the SCSI host bus adapter (HBA) already present in the backup server. The SCSI cable carries both data and control signals between the two devices and is the essential component needed to complete the physical connection.

The SCSI interface adapter is a built-in component of the tape library itself and is already present when the unit is unpackaged; it does not need to be separately acquired.

SCSI termination is a configuration requirement for the SCSI bus, but a termination card is not what connects the library to the server; the cable is the connection medium.

iSCSI is a protocol that encapsulates SCSI commands over IP/Ethernet networks and uses standard Ethernet cables, not the physical SCSI interface used by the tape library described.
