考题
单选题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？ （）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 aperinterface 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.
