When configuring a routed port on a Cisco multilayer switch, which configuration task is needed to
enable that port to function as a routed port?

A.
Enable the switch to participate in routing updates from external devices with the router
command in global configuration mode.

B.
Enter the no switchport command to disable Layer 2 functionality at the interface level.

C.
Each port participating in routing of Layer 3 packets must have an IP routing protocol assigned
on a per-interface level.

D.
Routing is enabled by default on a multilayer switch, so the port can become a Layer 3 routing
interface by assigning the appropriate IP address and subnet information.

Explanation:
To disable Layer 2 functionality at the interface level the command no switchport is used. This
command switches the port status from switched to routed.
