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.
Explanation: 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.
