What is the purpose of a default gateway on a host ?

  • A.To assign IP addresses to the host
  • B.To forward traffic destined for networks outside the local one
  • C.To translate domain names into IP addresses
  • D.To encrypt outgoing packets

Answer: D

Correct answer: To forward traffic destined for networks outside the local one

When a host finds that a destination address does not lie on its own subnet, it sends the packet to the default gateway, normally the local router, to be routed onward. Assigning addresses is the work of DHCP and name resolution that of DNS.
