Geographically speaking, a ______ links two or more distant sites.

A SAN (Storage Area Network) is a specialized high-speed network for connecting servers to shared storage devices, not a solution for geographic site connectivity.

A PAN (Personal Area Network) covers only a very small area, typically within a few meters of a person, such as Bluetooth connections between personal devices.

A LAN (Local Area Network) is limited to a single building or floor and is not designed to span geographically distant sites.

A CAN (Campus Area Network) connects buildings within a confined campus area and does not extend to geographically distant locations.

A Wide Area Network (WAN) is specifically defined as a network spanning large geographic areas, connecting distant locations such as branch offices across cities or countries using technologies like MPLS or leased lines. This geographic scope is its defining characteristic and distinguishes it from all other listed network types. No other option in the list is designed for connecting truly distant, geographically separate sites.
