Refer to the exhibit.

You want to enable these three actions:
* Enable the fa0/1 router's interface to obtain its interface IP address dynamically from a DHCP server.
* Enable the router to configure the next hop ip address of the default route automatically based on the DHCP response.
* Enable the router to act as the DHCP server for other clients connected to the router fa0/2 interface.
