Correct answer & explanation
✓
Non-edge port transitions to forwarding
In Rapid PVST+, a topology change is triggered when a non-edge port transitions to forwarding. The switch then sets the proposal bit on its designated ports, sends a proposal message, and expects an agreement from the downstream switch. After receiving the agreement, the port moves to forwarding and the switch propagates the change by setting the TC flag in BPDUs sent on all designated ports. This ensures rapid convergence.
