  2. Each leaf switch is connected to each spine switch.
  3. Each leaf switch is connected to two spine switches, making a loop.
  4. Each leaf switch is connected to a central leaf switch, then uplinked to a core spine switch.

Answer(s): B



What is the primary effect of the spanning-tree portfast command?

  1. It immediately enables the port in the listening state.
  2. It immediately puts the port into the forwarding state when the switch is reloaded.
  3. It enables BPDU messages.
  4. It minimizes spanning-tree convergence time.

Answer(s): D

What occurs when PortFast is enabled on an interface that is connected to another switch?

  1. Root port choice and spanning-tree recalculation are accelerated when a switch link goes down.
  2. After spanning-tree converges, PortFast shuts down any port that receives BPDUs.
  3. VTP is allowed to propagate VLAN configuration information from switch to switch automatically.
  4. Spanning-tree fails to detect a switching loop increasing the likelihood of broadcast storms.

Answer(s): D

Explanation:

Enabling the PortFast feature causes a switch or a trunk port to enter the STP forwarding-state immediately or upon a linkup event, thus bypassing the listening and learning states.
Note: To enable portfast on a trunk port you need the trunk keyword “spanning-tree portfast trunk”
