Which of the following statements is true about the Forward Delay timer of STP?
A.
Reduce the interval for sending BPDUs.
B.
Improve the STP convergence speed.
C.
Improve the configuration BPDU lifetime, ensuring that the configuration BPDUs can be forwarded to more switches.
D.
Prevent temporary loops.
E.
Delay is required when a port transitions between Blocking and Disabled.
The Answer Is:
D
This question includes an explanation.
Explanation:
The Forward Delay timer in STP helps prevent temporary loops by setting a delay for ports transitioning through Listening and Learning states before reaching the Forwarding state. This wait period ensures that all switches have updated topology information, reducing the risk of broadcast storms or loops​.
