Clients on a subnet are unable to obtain addresses automatically from a server located on a different subnet. As a network administrator, what configuration change should you make on the router to allow the clients to receive addresses from the server?
Configure a helper address on the router to forward client requests to the server.
Enable proxy ARP on the router interface connected to the clients.
Enable Network Address Translation (NAT) on the router.
Configure a static route to the server's subnet on the router.
Configuring a helper address on the router enables it to forward broadcast requests, such as those for Dynamic Host Configuration Protocol (DHCP), from clients to the server on a different subnet. Routers do not forward broadcasts by default, so without this configuration, the DHCP requests cannot reach the server. Configuring a static route does not handle broadcast traffic. Enabling Network Address Translation (NAT) modifies addresses for traffic passing through the router but doesn't forward DHCP broadcasts. Enabling proxy ARP allows the router to respond to Address Resolution Protocol (ARP) requests on behalf of other devices but doesn't help in forwarding DHCP requests across subnets.
