Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Port transitions to forwarding
In Rapid PVST+, the correct order of the topology change notification process is: first, the switch sends a proposal message on its designated port (B). The neighbor receives the proposal and synchronizes port roles (C). Then the neighbor sends an agreement message back (D). After agreement, the port transitions to forwarding (A). Finally, the switch propagates the topology change via the TC-while timer (E). This sequence ensures loop-free convergence.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Port transitions to forwarding
Why this is correct
Port transitions to forwarding after the agreement is received; it is the fourth step.
- ✓
Switch sends proposal message on designated port
Why this is correct
Switch sends proposal message on designated port to initiate synchronization; it is the first step.
- ✓
Neighbor receives proposal and synchronizes port roles
Why this is correct
Neighbor receives the proposal and synchronizes its port roles; it is the second step.
- ✓
Neighbor sends agreement message back
Why this is correct
Neighbor sends an agreement message back to confirm synchronization; it is the third step.
- ✓
Switch propagates topology change via TC-while timer
Why this is correct
Switch propagates the topology change via the TC-while timer after the port is forwarding; it is the final step.
