Which of the following is NOT an example of a network configuration?

LAN

WAN

SAN

MAN

Of the options presented in the problem, SAN would be the the exemption of the 4 which is not a network configuration.

LAN or Local Area Network, MAN or Metropolitan Area Network, and WAN or Wide Area Network are examples of a network configuration and are arranged in this solution by their capacity area if they were to be ranked. SAN or Storage Area Network only deals with storage devices and aren't that much connected with the other three presented in the problem.
