Which answers list a criterion for choosing which router interfaces need to be configured as a DHCP relay agent? (Choose two answers.)

  • If the subnet off the interface does not include a DHCP server
  • If the subnet off the interface does include a DHCP server
  • If the subnet off the interface contains DHCP clients
  • If the router interface already has an ip address dhcp command

Explanation: A router needs to act as a DHCP relay agent if DHCP clients exist on the connected subnet and there is no DHCP server in that subnet. If a DHCP exists in the subnet, the router does not need to forward DHCP messages to a remote DHCP server (which is the function of a DHCP relay agent). The answer that mentions the ip address dhcp command makes the router interface act as a DHCP client and has nothing to do with DHCP relay agent.
