A customer support center employs 10,000 people with their own associated IP addresses, and operates over 250 servers, including e-mail servers, FTP servers, Web servers, and DHCP at the three locations:

• New York City, New York
• Atlantic City, New Jersey
• Wilmington, Delaware

Dual T1 lines, for a total aggregate bandwidth of six Mbps, link the three sites, and each site contains roughly third of the employees as well as the servers. Per force, each site operates on multiple, separate subnets inside a single Class B address that the company owns.

Based on your understanding of the above scenario, write report in a Microsoft Word document that answers the following:

• Make a case for setting up a single, separate DNS server at each location and explain how each is a backup disaster recovery (DR) for the other.
• What benefits does the above DR strategy provide the employees at the other locations?
• Explain how the relative speed of the 100 Base T local area networks (LANs) used at each location compares to accessing the wide area network (WAN) link between the two sites.
