Which serial 0/0/0 interface state will be shown if no serial cable is attached to the router, but everything else has been correctly configured and turned on?

  • Serial 0/0/0 is up, line protocol is up
  • Serial 0/0/0 is up (looped)
  • Serial 0/0/0 is up (disabled)
  • Serial 0/0/0 is up, line protocol is down
  • Serial 0/0/0 is down, line protocol is down
  • Serial 0/0/0 is administratively down, line protocol is down

Explanation: The show interfaces privileged exec mode command shows the state of the interfaces, along with much other information that related to them. "Serial 0/0/0 is down, line protocol is down" is displayed if there is no cable connected because there is no Layer 1 or Layer 2 activity going on. The interface has been turned on by the use of the no shutdown command, otherwise the "Serial 0/0/0 is administratively down, line protocol is down" message would be displayed, whether a cable has been connected or not.
