Refer to the exhibit. If the IP addresses of the default gateway router and the DNS server are correct, what is the configuration problem?
- The default-router and dns-server commands need to be configured with subnet masks.
- The DNS server and the default gateway router should be in the same subnet.
- The IP address of the DNS server is not contained in the excluded address list.
- The IP address of the default gateway router is not contained in the excluded address list.
In this configuration, the excluded address list should include the address that is assigned to the default gateway router. So the command should be ip dhcp excluded-address 192.168.10.1 192.168.10.9.
