Question:
A host on the 10.10.100.0/24 LAN is not being assigned an IPv4 address by an enterprise DHCP server with the address 10.10.200.10/24. What is the best way for the network engineer to resolve this problem?

• Issue the command ip helper-address 10.10.200.10 on the router interface that is the 10.10.100.0/24 gateway.
• Issue the command default-router 10.10.200.10 at the DHCP configuration prompt on the 10.10.100.0/24 LAN gateway router.
• Issue the command ip helper-address 10.10.100.0 on the router interface that is the 10.10.200.0/24 gateway.
• Issue the command network 10.10.200.0 255.255.255.0 at the DHCP configuration prompt on the 10.10.100.0/24 LAN gateway router.

Explanation: The DHCP server is not on the same network as the hosts, so DHCP relay agent is required. This is achieved by issuing the ip helper-address command on the interface of the router that contains the DHCPv4 clients, in order to direct DHCP messages to the DHCPv4 server IP address.
