Does anyone have a good answer to this question? I happen to agree that one cannot determine which path would be blocked on switch D.
For example: if the link between switch D and switch C was 100Mbp, the link between switch D & A was 1000Mbps, and the link between switch A & E was 1000Mbps, wouldn't STP block on the 100Mbps link?
To me, the answer given is a bit vague. Just because switch A's link to switch E is the root port, doesn't mean the traffic has to follow that path.
Can someone please give a more detailed reason why traffic would follow the A-E-C-D path versus the A-D path?
