A firm's office in one country and its office in another country are connected by a carrier circuit. Which network type is that circuit?
Select an answer to reveal the explanation.
Short Explanation
The two offices are far enough apart to need a carrier, and they are not in the same building or the same city block. You call that circuit a wide area network. A headset bubble, one office switch, or a disk fabric is a different kind of network.
Full Explanation
A wide area network connects sites across long distances, typically through a carrier. Offices in two countries on a carrier circuit match a WAN. A personal area network is the short space around one person. Two countries are far outside it. A local area network is one limited place, such as a single office. A carrier circuit between countries is not inside one building. A storage area network carries storage traffic. A general link between offices is not reserved for disks. Exam caveat: the firm can still run a LAN inside each office. The circuit between the countries is the WAN, even if each end hands off to a local switch. Operational check: trace the carrier circuit on the diagram between the two countries and confirm each office routes to the other over it. Mark the carrier circuit ID on the diagram between the two countries. Ping a host in the other country over that circuit after the routes are in. Document which router at each office faces the carrier.
