ITPEC IP April 2021 Question 34
ITPEC IP April 2021 — Question 34 of 100
A WAN connects geographically separated locations, often by using a telecommunications carrier's network service. An organization can link its head office, branches, and data centers across cities or regions into one wide-area network.
Answer (c)
Why not others:
- an Internet-based VPN is one possible way to construct a WAN, not the general definition
- a WAN can connect locations within one country as well as across countries
- the certified brand for interoperable IEEE 802.11 devices is Wi-Fi
Key rule: LAN describes a limited local area; WAN spans separated sites through carrier or other long-distance network services.
