nadine is the systems administrator for a network with a single subnet. The subnet uses 192.168.1.0 with a mask of 255.255.255.0. The network has 10 servers running Windows Server. Srv1 currently provides both DHCP and DNS services. Nadine wants to increase the fault tolerance for her DHCP servers. She installs a new server, Srv11, and configures it for DHCP. She configures a scope on Srv11 to match the scope on Srv1 and then excludes half of the addresses in the scope on Srv1 and the other half of the addresses on the Srv11. Nadine decides to test her solution and shuts down Srv1. As a test, she forces a workstation to release its IP address and request a new one. She finds that the workstation has the IP address 169.254.0.15 with a mask of 255.255.0.0. What should Nadine do to fix the problem?
