Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q271-Q276):

NEW QUESTION # 271
Refer to the exhibit.

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

A. The max_age and forward delay parameters can be adjusted to speed up STP convergence process.
B. Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.
C. The transit_delay=5 and bpdu_delay=20 are recommended values, considering hello_timer=2 and specified.
D. Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in
802.1d to speed up STP convergence process.

Answer: A

Explanation:
* In 802.1d STP, convergence is influenced by hello timer, max_age, and forward_delay.
* While hello_timer typically remains at 2 seconds, lowering max_age (default 20s) and forward_delay (default 15s) can speed up convergence.
* Forward_delay controls the time spent in listening and learning states; max_age determines how long a BPDU is considered valid before recalculating topology.
Why other options are incorrect:
* A, B, D: These timers (transit_delay, bpdu_delay, maximum_transmission_halt_delay) are not directly adjustable parameters in 802.1d implementations.
