Which of the following networks connect to form a WAN?

A wide area network (WAN) is designed to cover large geographical areas and connect multiple local area networks (LANs). Therefore, when two or more LANs connect, they create a WAN. This connection facilitates communication and data sharing across different locations, which is essential for businesses or organizations that operate in multiple sites.

The other options do not effectively define a WAN. Multiple remote clients typically refer to individual devices or users that connect to a network but do not form a network on their own. A single Intranet is a private network designed for internal use within an organization, while a standalone server operates independently and does not connect to other networks in a way that would constitute a WAN. These distinctions emphasize how connecting multiple LANs is crucial for the broader connectivity that defines a WAN.
