When configuring a routed port on a Cisco multilayer switch, which of these is a required configuration task that you must perform to enable that port to function as a routed port? Select the best response.
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.
