Which of the following expansion cards should be installed in a server to allow the server to connect to a SAN via a fiber channel?

SATA is a local storage interface standard used to connect internal hard drives and SSDs directly to a motherboard, not a SAN.

iSCSI is a storage protocol that runs over standard Ethernet networks, not Fiber Channel, and requires a NIC or dedicated iSCSI adapter rather than an HBA.

SCSI is a parallel interface standard for locally attached storage devices and does not provide Fiber Channel SAN connectivity.

An HBA is a dedicated expansion card that provides a Fiber Channel interface, allowing a server to communicate with a SAN fabric. It contains the necessary ports, controllers, and drivers to establish high-speed, low-latency Fiber Channel connections to shared storage. Without an HBA, a server has no physical means to attach to a Fiber Channel SAN.
