• Question 61:

  Refer to the exhibit.

  

  This network is running legacy STP 802.1 d. Assuming "hello_timer" is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?

  A. Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in 802.1d to speed up STP convergence process.

  B. The max_age and forward delay parameters can be adjusted to speed up STP convergence process.

  C. The transit_delay=5 and bpdu_delay=20 are recommended values, considering hello_timer=2 and specified diameter.

  D. Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.

  Correct Answer: B
