A university interconnects multiple buildings using fiber-optic cabling. Which type of network is being used?

A storage area network (SAN) is a specialized network that provides access to consolidated, block-level data storage. SANs are typically used in data centers to enhance storage devices’ accessibility and performance, rather than interconnecting buildings like a CAN does. Therefore, this option does not apply to the context of connecting university buildings.

A wide area network (WAN) covers a broad geographic area, often connecting multiple local area networks (LANs) across cities or countries. Although a WAN can interconnect buildings over large distances, it is not typically limited to a single campus environment like a CAN, making it an incorrect choice for this scenario.

A metropolitan area network (MAN) connects networks within a city or a large campus but is more extensive than a CAN. While it could theoretically serve a university that spans a city, the question specifically indicates multiple buildings, which falls more appropriately under the definition of a CAN than a MAN.
