Refer to the exhibit. The administrator wants to enable port security on an interface on switch S1, but the command was rejected. Which conclusion can be drawn?

  • The interface must be initially configured with the switchport mode trunk command.
  • The interface needs to be configured initially with an IP address.
  • The interface needs to be previously configured with the no shutdown command.
  • The interface must be initially configured with the switchport mode access command.

Explanation: To enable port security, use the switchport port-security interface configuration command on an access port. By default, Layer 2 switch ports are set to dynamic auto (trunking on); therefore, the port must be initially configured as an access port before port security can be enabled.
