What should Dorene do to configure the DHCP relay agent effectively after specifying the DHCP server IP?

To configure the DHCP relay agent effectively, it is essential to ensure that it listens for DHCPDISCOVER packets on a network interface. This step is crucial because the DHCPDISCOVER packets are the initial messages sent by clients looking for a DHCP server to obtain an IP address and other network configuration details. By correctly configuring the relay agent to listen for these packets, the relay can effectively process incoming requests from clients and forward them to the specified DHCP server. This functionality allows devices on different subnets to communicate with the DHCP server, enabling network configuration management across a broader range of devices.

In contrast, simply rebooting the remote access server does not directly contribute to the configuration of the DHCP relay agent itself. Also, forwarding authentication requests to a RADIUS server focuses more on authentication aspects and does not pertain to the DHCP relay functionality. Finally, while adding a DHCP relay agent for IPv6 is relevant for environments that require IPv6 support, it does not address the configuration process for forwarding DHCP requests for IPv4 clients, which is typically the primary concern in many networks.
