WANs are used to connect networks over large geographical areas such as to which?

• A. An ISP
• B. A single room
• C. A campus building
• D. A home network

Answer: (A)

Wide Area Networks connect networks over large geographic distances, enabling inter-network communication across cities, regions, or countries. To move data across such distances, WANs rely on carrier networks and Internet service providers that provide the long-haul transport between sites. That’s why connecting to an Internet service provider is the best fit for WAN usage: it supplies the wide-area connectivity that links different networks together and to the broader Internet.

A single room, a campus building, and a home network are all typically local or campus networks, designed for smaller, localized coverage rather than spanning large distances.
