Which one of the following statements correctly describes a characteristic of WANs?
WANs can be built by connecting multiple LANs via wired or wireless links.
A Wide Area Network (WAN) spans a large geographic area and is typically formed by interconnecting many smaller Local Area Networks (LANs).
The links joining these LANs can be wired (leased lines, optical fibre) or wireless (microwave, satellite), so a WAN is not tied to any single medium.
WANs can be public or private, are not limited to a 1 to 2 km radius (that describes a LAN), and are not exclusively wireless.
Hence, the answer is WANs can be built by connecting multiple LANs via wired or wireless links.
