Wilke's Environmental Group, a large organization that provides environmental services such as water quality monitoring and geological surveys to businesses and government agencies across the nation, seeks your help in designing its corporate WAN. It plans to completely replace its legacy hodgepodge of connections and services. Headquartered in Baton Rouge, Louisiana, the firm also has large, regional offices in Seattle, Phoenix and Boston.
Required:
? The offices need a way to exchange e-mails and large files.
? Most of the firms's 500 engineers and Technical Specialists spend at least half their time on the road and while mobile, they need to upload data to their regional offices.
? At other times, they work from home and need fast and reliable connections to their regional offices.
The IT manager makes it clear that the environmental services business is booming and so you should not necessarily seek economical solutions.

3.1.1.1 Office-to office (10)
3.1.1.2 Mobile user- to office (10)
