Spanning tree sim - confused

[contiva]

I'm having a mental block with Q S.22 ( spanning tree sim). if host A needs to contact Server 1 and given the information in the topology - surely the link between Switch D & Switch A would be up?

Without link costs there are multiple permutations - am I missing something from this question.....

Either A-D or C-D could be blocked, likewise A-B or B-C could be blocked..

please convince me A-E-C-D is the correct answer  ???

thanks in advance

ok - packet tracer has convinced me - the real route is A-E-C-D.........

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?
