Which term denotes a network that spans a metropolitan region and interconnects multiple LANs?

• A. Metropolitan Area Network (MAN)
• B. Multicast
• C. Modem
• D. Masquerading

Answer: (A)

Metropolitan Area Network describes a network that spans a metropolitan region and interconnects multiple LANs. It sits between a local area network, which covers a single site, and a wide area network that can span large distances. A MAN is built to link several campuses, buildings, or office networks within a city, delivering higher-speed connectivity across the metro area—often using fiber and Metro Ethernet or MPLS technologies. That geographic scope is exactly what the question asks for: a network that interconnects multiple LANs across a city.

Multicast is a data-delivery method to reach a group of hosts, not a type of network. A modem is a device that modulates and demodulates signals to enable connectivity over telephone lines, not a network category. Masquerading refers to NAT-like address translation or deception techniques, not a network scope.
