A network administrator correctly configures a DHCP server that is serving JumpStart and non-JumpStart clients. One of the DHCP clients asks for an IP address. It does NOT ask for any other parameters such as subnet mask, router, and encapsulated vendor options.

A variable must be modified in the /etc/default/dhcpagent file on the client to configure the DHCP client’s dhcpagent to request additional networking information from the DHCP server.
