On what switch ports should PortFast be enabled to enhance STP stability?
- all end-user ports
- only ports that attach to a neighboring switch
- all trunk ports that are not root ports
- only ports that are elected as designated ports
Explanation: PortFast will immediately bring an interface configured as an access or trunk port to the forwarding state from a blocking state, bypassing the listening and learning states. If configured on a trunk link, immediately transitioning to the forwarding state could lead to the formation of Layer 2 loops.
