Which of the following connection types should a technician use to connect a server to a SAN?

SATA is a direct-attached storage interface used to connect drives internally within a server or workstation and has no capability for SAN fabric connectivity.

Fibre Channel is a purpose-built, high-throughput networking technology designed specifically for SAN connectivity, operating at speeds of 8, 16, or 32 Gbps over a dedicated FC fabric. Servers use FC Host Bus Adapters (HBAs) to connect to FC switches, which then provide access to SAN storage arrays with predictable, low-latency block-level I/O. FC is the dominant protocol for enterprise SAN environments due to its reliability, performance, and dedicated network isolation from LAN traffic.

SAS is used for direct-attached storage and some storage enclosures but is not the standard protocol for connecting a server to a SAN fabric.

Parallel SCSI is a legacy direct-attached interface with severe cable length limitations and a low device count ceiling, making it entirely unsuitable for SAN connectivity.
