IP Connectivity

Which command must be entered so that the default gateway is distributed automatically when DHCP is configured on a router?

  • A dns-server
  • B default-router
  • C ip helper-address
  • D default-gateway
Explanation

On a Cisco router acting as a DHCP server, the default-router command is configured under the DHCP pool to advertise the clients’ default gateway through DHCP. The other commands serve different purposes: dns-server supplies DNS information, ip helper-address forwards client broadcasts to a remote DHCP server, and default-gateway does not define the gateway value handed out by the router’s DHCP pool.
