XYZ Corporation employs 40,000 people, with their own associated IP addresses, and operates over 400 servers, including email (SMTP and POP3), FTP, Web, and DHDP at two locations: one in Muncie, Indiana, the other about 20 miles away in Hartford City. Dual T1 lines, for total aggregate bandwidth of 3.088 Mbps, link the two sites, and each site contains roughly half of the employees and servers. Perforce, each site operates on multiple, separate subnets inside a single Class B address that the company owns. Make a case for setting up a single, separate DNS server at each location, explaining how each might back up the other, and what benefits this might provide for XYZ Corporation users. Explain how the relative speed of the 100BaseT LANs used at each location compares to accessing the WAN link between the two sites.
