What do you need to enable on the router to support a single DHCP server in a routed network?

• A. Dynamic routing
• B. BOOTP forwarding
• C. IP forwarding
• D. Network Address Translation

Answer: (B)

To support a single DHCP server in a routed network, enabling BOOTP forwarding is essential. DHCP (Dynamic Host Configuration Protocol) is fundamentally built upon the BOOTP (Bootstrap Protocol) specifications, which means BOOTP forwarding plays a critical role in facilitating DHCP requests from clients to the DHCP server across different segments of a routed network. When a DHCP client broadcasts a request for an IP address, these broadcasts are limited to the local subnet. However, if the DHCP server is located on a different subnet, the router needs to be configured to forward these broadcast requests. BOOTP forwarding allows the router to listen for DHCP (or BOOTP) requests and subsequently forward those requests to the designated DHCP server, allowing the clients in various subnets to receive IP address assignments. Dynamic routing, IP forwarding, and Network Address Translation serve different roles in network operations but do not specifically address the requirement of forwarding DHCP packets between clients and servers over different network segments. Therefore, enabling BOOTP forwarding is the appropriate action to ensure DHCP communication is maintained across routed networks.
