Canyon College plans to offer night classes for business school students, paralegal students, and nurses, in five remote cities. Their plan is to have professors offer the classes from the main site, and to use video conferencing and multimedia options at the remote sites. At the main site, they have a TCP/IP Ethernet network. The remote sites, which are not yet set up, will also have TCP/IP Ethernet networks. The Canyon College director of information technology is asking you to recommend two WAN options to connect the remote sites to the main campus, and to provide a rationale for the options you recommend.
Prepare a sample network diagram, and indicate your recommended options.
