What is the purpose of adding a DHCP relay agent on a remote access server?

The purpose of adding a DHCP relay agent on a remote access server is to forward DHCP requests to a DHCP server. This function is crucial in network environments where clients are situated on different subnets than the DHCP server. When a client device needs an IP address, it sends a DHCP request that is broadcasted across the local network. However, broadcast messages cannot cross subnet boundaries.

The DHCP relay agent acts as an intermediary that listens for these requests on the local subnet and then forwards them to the appropriate DHCP server, which may be located on a different subnet. By doing so, it facilitates the process of obtaining IP configuration information for clients located far from the DHCP server, enhancing network efficiency and management.

In contrast, other options do not relate to the specific functionality of a DHCP relay agent. Rebooting the server remotely refers to remote management capabilities, managing user accounts pertains to user authentication and administration, and enabling remote desktop functionality is about allowing remote access to server desktops, none of which relate to the primary role of a DHCP relay agent in the context of IP address assignment.
