You work for the city’s Department of Motor Vehicles (DMV). There are five DMV locations spread out across the city that you have been asked to connect with a network. You have created a list of requirements for this network, including that it must be wired and support at least 1 Gbps of bandwidth. Which of the following network types would MOST likely be used for the DMV to connect their internal networks across the city securely?
- PAN
- WAN
- MAN
- LAN
Answer : MAN
Overall explanation : A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan or city area. This is the most appropriate choice based on the requirements provided. MAN is a term applied to the interconnection of local area networks (LANs) or campus area networks (CANs) across a city into a single larger network. A MAN is larger than a CAN or LAN but smaller than a WAN. A local area network (LAN) is a network where all the nodes or hosts participating in the network are directly connected with cables or short-range wireless media. A wide area network (WAN) is a network that spans multiple geographic locations such as the internet. Wide area networks are often established with leased telecommunication circuits. A personal area network (PAN) is a close-range network that is usually based on Bluetooth or NFC for communications between personal devices, such as smartphones, laptops, printers, and other peripheral devices.
