The network contains an Active Directory domain named contoso.com that has three Active
Directory sites named Site1, Site2,and Site3. The New York office is located in Site1. The
Chicago office is located in Site2. The Atlanta office is located in Site3. There is a local IT
staff to manage the servers in each site. The current domain controllers are configured as shown in the following table.
