Which network type interconnects multiple LANs?

• A. WAN (Wide Area Network)
• B. LAN (Local Area Network)
• C. VPN (Virtual Private Network)
• D. MAN (Metropolitan Area Network)

Answer: (A)

A Wide Area Network is designed to connect multiple Local Area Networks across large geographic distances. It links separate LANs from different buildings, campuses, or cities using routing and various transmission media (like leased lines, MPLS, or broadband Internet) so data can travel between sites as if they’re one giant network. Local Area Networks stay confined to a single location, Metropolitan Area Networks cover a city-wide area but not across long distances, and Virtual Private Networks provide secure connections over public networks rather than being the network type that inherently ties multiple LANs together. So, the network type that interconnects multiple LANs is a Wide Area Network.
