d and e is the answer
D and E are correct, however I think the question is poorly phrased. Though RSTP does use only thee port states (forwarding, learning, discarding), it doesn't really transition "through" forwarding.
To Answer Your Question: When considering the transition states in RSTP, the ports transition through Blocking and Learning before reaching the Forwarding state. So, Forwarding is indeed a state that a port can end up in, but it’s not considered a transitional state through which the port moves during the RSTP process. Instead, it’s the final operational state for ports that are actively forwarding traffic. Therefore, the Correct Answer to Your Question: The two states a switch port transitions through while using RSTP (802.1w), aside from discarding, are indeed: A. Blocking D. Learning This is because "Blocking" and "Learning" are the states a port transitions through as it moves towards "Forwarding." "Forwarding" is the endpoint state but not one of the transitional states.
