What command will you type to enable a switch's interface to be a routed interface instead of a switched interface?

(A) routed interface
(B) enable interface
(C) no switch interface
(D) no switchport

no switchport is the correct answer. To make a switch interface a routed interface instead of a switched interface just use the no switchport subcommand on the physical interface. To make the port stop acting like a switch port and instead act like a router port, use the no switchport command on the interface.
