Answer: B - WAN, or wide area network, is technology that is used to communicate over a large geographical area. WAN traffic may have to travel hundreds or thousands of miles and pass through several different types of devices, cable, and protocols. Because of this difference, most LAN MAC protocols are connectionless and most WAN communication protocols are connection oriented. Connection-oriented protocols provide reliable transmission because they have the capability of error detection and correction.
