Your network is configured as shown in the exhibit. "Engineering! and Salesl have DHCP installed up them." All the servers are Windows 2000 Server computers that use TCP/IP as the only network protocol. The sales department uses one subnet and has servers named Salesl and Sales2. The engineering department uses another subnet and has servers named Engineeringl and Engineering2. Salesl and Engineeringl are configured to act as DHCP servers. The router that joins the two subnets is not RFC 1542 compliant and does not support DHCP/BOOTP relay. You want to allow Salesl and Engineeringl to support client computers on each other's subnets.

Your network contains 10 domain controllers, 10 member servers, and approximately 1,000 client computers. All the servers run Windows 2000 Server, and all the client computers run Windows 2000 Professional. Two of the domain controllers act as DNS servers. Users of client computers use file sharing to grant access to files stored locally. The network has 10 subnets and uses TCP/IP as the only network protocol. You want to configure the network so that all computers can resolve the addresses of all other computers by using DNS. Client computers must be able to register and resolve addresses if a server fails. How should you configure the DNS servers?
