ITPEC IP October 2019 Question 33
ITPEC IP October 2019 — Question 33 of 100
A WAN connects geographically separated sites, often by using communication services supplied by a network operator. A company can use it to link a head office with branches across cities, regions, or countries.
Answer (c)
Why not others:
- a VPN is one technology that can create a private connection but is not the definition of every WAN
- a WAN can connect distant regions within one country as well as different countries
- (d) describes Wi-Fi certification for interoperable IEEE 802.11 products
Key rule: LAN describes a limited local area; WAN describes connectivity across geographically separated locations.
