Which two states are the port states when RSTP has converged? (choose two)
Answer: A D
RSTP only has 3 port states that are discarding, learning and forwarding. When RSTP has converged there are only 2 port states left: discarding and forwarding but the answers don’t mention about discarding state so blocking state (answer A) may be considered the best alternative answer
blocking too is not correct and useless in such state it must be discarding
Look like this question had difference answer from many sources, which one is correct?
I think B and D! Because RSTP has three types of port states: discarding, learning and forwarding.”disabled” is nonsense…
If it’s learning then it’s not converged.
B – no…
A and D.
STP (802.1D) RSTP (802.1w)
•The port is in the blocking state, which means discarding in a stable topology.
Yesterday i passed 200-120 and this question was in my exam with available answers such as:
So, right answers is A and D.
Looks like Cisco fixed it.
Answer is B & D. In RSTP a number of port states now come under ‘Discarding’.
A. blocking -> Discarding
C. disabled -> Discarding
E. listening -> Discarding.
So the only 2 RSTP port states listed are B & D. B doesnt sounds right in a converged network, however, according to Cisco the ‘Learning’ state is present in an Active topology (ie converged?):
