The administrator wants to have central storage for all of the files to be stored for each VM. Which of the following is used to connect a host to a SAN utilizing a fiber connection?

A VNIC (Virtual Network Interface Card) is a software-defined network adapter within a virtual machine, used for network connectivity, not for physical SAN fiber connections.

A NIC (Network Interface Card) is a hardware component that connects a computer to a computer network, typically Ethernet, and is not designed for Fibre Channel SAN connections.

A Host Bus Adapter (HBA) is a circuit board or integrated circuit adapter that connects a host system, such as a server, to a storage network, most commonly a Fibre Channel SAN. HBAs facilitate high-speed data transfer between the host and the shared storage resources.

A SCSI adapter is primarily used to connect hosts to SCSI-based storage devices, which are typically direct-attached or SAS, not specifically Fibre Channel SANs which use HBAs.
