   In a Rapid PVST+ topology, a switch has two ports connected to the same segment (another switch). One port is the designated port and the other is in discarding state. What is the role of the discarding port?

   • ADisabled port
   • BBackup port
   • CRoot port
   • DAlternate port

   What does BPDU guard do when it receives a BPDU on a PortFast-enabled port?

   • BIt ignores the BPDU and keeps the port forwarding
   • CIt shuts down the port
   • DIt blocks the port but keeps it administratively up

   What is the purpose of a blocked (alternate) port in Rapid PVST+?

   • ATo connect to end devices such as PCs
   • BTo provide a redundant path that is ready to forward if the current root port fails
   • CTo send BPDUs to the root bridge
   • DTo forward traffic immediately to increase bandwidth

   In Rapid PVST+, what is the role of a designated port?

   • AIt forwards traffic toward the root bridge
   • BIt blocks traffic to prevent loops
   • CIt provides the best path for traffic from the attached segment toward the root bridge
   • DIt listens for BPDUs but does not forward traffic
