I'd read the question again and ensure what I thought it said and then how I
interpretted what it said. If there was still confusion I'd explain to the
proctor a few things I knew and why I think I knew them to be that way.
Now if we've practiced this scenario a few times, understand why spanning
tree must function as, know what the root of spanning-tree is, should
be, and is not, and finally know whether or not any sort of redundancy is
required... we might not need to ask the proctor any more.
