   In Rapid Spanning Tree Protocol (RSTP), what is the purpose of the proposal/agreement handshake?

   • ATo elect a new root bridge
   • BTo update the MAC address table
   • CTo rapidly transition a port to forwarding without waiting for timers
   • DTo detect a loop in the network

   A network administrator is troubleshooting a spanning tree issue in a network that runs classic STP. A new switch is connected to the network, and the administrator notices that the new switch's ports are stuck in the listening state for longer than expected. What is the most likely cause?

   • AThe new switch has a lower bridge priority than the root bridge.
   • BThe max age timer is set too low on the new switch.
   • CThe forward delay timer is set too high on the new switch.
   • DThe new switch is not receiving BPDUs from the root bridge.

   A network administrator is troubleshooting a problem in an RSTP network. After a link failure, the network converges, but the administrator notices that some MAC addresses are not reachable for a few seconds after convergence. The administrator suspects that the MAC address table on a switch is not being flushed properly. What is the most likely cause of this issue?

   • AThe switch has a large MAC address table and needs more time to flush entries.
   • BThe switch is running classic STP instead of RSTP.
   • CThe MAC aging timer on the switch is set too high.
   • DThe switch that detected the link failure did not send a topology change notification.

   How does an RSTP edge port behave differently from a non-edge port?

   • AIt transitions directly to forwarding without going through the learning state
   • BIt is always a root port
   • CIt sends BPDUs more frequently
   • DIt is automatically protected from root bridge election
