A server supports a maximum of six hot-swap hard drives. It currently has four drives installed. The administrator has a bare hard drive on hand as a cold spare. Which of the following parts would…

A SATA cable is required to physically connect the bare drive to the server's internal storage controller or backplane port, which transitions it from a cold spare (stored off-system) to a hot spare (installed, recognized, and available for automatic failover). Without this cable, the drive cannot be detected by the system or designated as a hot spare by the RAID controller. The cable is the single missing component that makes the drive active inside the chassis.

A drive tray is a mounting carrier used in dedicated hot-swap bay enclosures; it is not required when installing a drive via a direct internal SATA cable connection to an available controller port.

A SAS interposer is an adapter that allows SATA drives to seat in SAS backplane slots; it is not needed for a straightforward SATA cable connection to an available port.

A redundant controller provides fault tolerance for the storage controller itself and is not a prerequisite for physically installing and connecting a single drive as a hot spare.
