Wow- I would say MAC if we were talking VLAN's (to & from port decisions),
but I'm guessing the "Cost Of The Attached Link," must be driving you toward
a protocol answer. I didn't think STP worked exactly in this way (maybe I
need to refresh). Anywho- don't spend your morning on this question. It's
a brain teaser @ best. Bits & data will continue to pass whether you know
this or not. The question is way too specific& up for grabs (IMHO) to be a
test question, but I will research it too :o)
