What are the two options that describe the effects of the spanning-tree portfast command? (Choose two.)

  • If the switch port is configured with PortFast, it waits 15 seconds before transitioning from a blocking to forwarding state.
  • Enabling PortFast on trunks that connect to other switches improves convergence.
  • If a switch port is configured with PortFast, it is an access port that immediately transitions from a blocking to forwarding state.
  • Portfast enables the port to bypass the listening and learning states of STP.
  • Portfast bypasses the learning state and moves immediately into blocking.
Answers Explanation & Hints:

The portfast feature is enabled on a specific access port with the spanning-tree portfast command. One of the benefits of the STP portfast feature, is that the access ports bypass the earlier 802.1D STP states (learning and listening) and forward traffic immediately.
