• Question 486:

  Which two statements are true about STP and RSTP? (Choose two.)

  A. STP uses a proposal-and-agreement handshake on point-to-point links instead of timers.

  B. In RSTP, root ports and edge ports transition to the forwarding state immediately, without exchanging messages with other switches.

  C. In RSTP, a TCN is generated when a port transitions to the discarding state.

  D. In STP, the forwarding delay timer and maximum age timer define the convergence delay.

  Correct Answer: BD
