Explanation

An FC (Fibre Channel) HBA (Host Bus Adapter) is a specialized interface card installed in a server that enables it to communicate with Fibre Channel storage arrays - making C (Server and fiber array) correct. It acts as the bridge between the server's internal bus and the Fibre Channel fabric, giving the server block-level access to SAN storage.

Why the distractors are wrong:

• A is wrong because FC HBAs do not connect to IP Storage Arrays (e.g., iSCSI arrays); those require a standard NIC or iSCSI HBA, not an FC HBA. FC HBAs also don't link two storage arrays together.
• B is wrong because server-to-server communication uses standard network adapters (NICs), not FC HBAs, which are purpose-built for storage connectivity.
• D is wrong because IP-SAN (iSCSI-based) arrays communicate over TCP/IP and use NICs or iSCSI-specific adapters - FC HBAs only speak the Fibre Channel protocol, not IP.

Memory tip: Think of the acronym - FC (Fibre Channel) HBA connects to FC storage. If the target device uses "IP" in its name, it's not FC territory. FC = fiber storage only.
