Question

You are configuring an edge router interface with a public IP address for Internet connectivity. The router must obtain the IP address dynamically from the service provider.

Which command is required on interface FastEthernet 0/0 to accomplish this?

A ip default-gateway
B ip route
C ip default-network
D ip address dhcp
E ip address dynamic

Explanation

On Cisco IOS, an interface that should receive its IPv4 address automatically from an ISP uses the interface configuration command ip address dhcp. That command tells FastEthernet 0/0 to act as a DHCP client and learn its address dynamically. The other commands deal with default gateway or routing behavior, not dynamic interface address assignment.
