ITPEC IP October 2018 Question 34
ITPEC IP October 2018 — Question 34 of 100
Only example C requires a WAN. Communication between the Tokyo headquarters and Osaka branch spans geographically separate organizational sites, so their LANs must be connected through a wide-area network. Examples A and B remain within a server room or a university campus LAN.
Answer (d)
Why not others:
- A connects devices through the same local hub
- B accesses a server on the same campus LAN
- lists containing A or B incorrectly classify local communication as wide-area communication
Key rule: A LAN covers a limited local site; a WAN interconnects networks across distant locations such as separate cities or branches.
