A network administrator enters the spanning-tree portfast bpduguard default command. What is the result of this command being issued on a Cisco switch?

  • Any switch port will be error-disabled if it receives a BPDU.
  • Any trunk ports will be allowed to connect to the network immediately, rather than waiting to converge.
  • Any switch port that has been configured with PortFast will be error-disabled if it receives a BPDU.
  • Any switch port that receives a BPDU will ignore the BPDU message.
Answers Explanation & Hints:

The spanning-tree bpduguard default command will enable BPDU guard on all switch ports that have PortFast-enabled. This will put the port in an error-disabled state if a BPDU from another switch is received on a PortFast-enabled interface.
