All of the switches are running Rapid Spanning Tree Protocol (RSTP). Link 1 fails. Switch 2 needs to select a
new root port and begins to send messages to Switch 3 and Switch 4. What happens?

A.
Switch 3 and Switch 4 disable their ports to Switch 2, isolating Switch 2 from the network to prevent loops.

B.
Switch 3 and Switch 4 go through a waiting period and convergence process that takes about a minute.

C.
Switch 3 and Switch 4 accept Switch 2 as their root, causing them to disable their links to Switch 1.

D.
Switch 3 and Switch 4 initiate a negotiation with Switch 2, which allows convergence to occur in about a
second.
