1) Wilkes Environmental Group requires help in developing its corporate WAN. (It plans to completely substitute its legacy hodgepodge of the connections and services.) Headquartered in the Baton Rouge, Louisiana, the firm also has large, regional offices in Seattle, Phoenix, and Boston. These offices require a way in order to exchange the email and the large files. Most of firm’s 500 engineers and technical specialist spend at least half their time on the road and while mobile, they require uploading the data to their regional offices. While other times, they work from the home and require fast and the reliable connections to their regional offices. Explain at least two appropriate WAN technologies for each of the Wilke’s three connectivity situations: mobile user-to-office, office to office, and home-to-office. State the options do you recommend above all and also explain why?
