ITPEC IP October 2021 — Question 31 of 100
Communication between the Kyoto sales office and the Tokyo head office requires a WAN. The two LANs are located in different cities, so a wide area network is needed to connect them over the geographic distance.
Answer (d)
Why not others:
- file sharing among devices within one Osaka office uses its local LAN
- Bluetooth between a PC and printer in one house is a short-range personal area connection
- devices connected through a hub inside one server room are on a local network
Key rule: A LAN covers a limited local site, while a WAN interconnects networks across distant offices, cities, or regions.
