Got it,fellas, #9099, (sounds like a secret agent code or something). Of
course, I'll be hanging out here trying to return the favors. Thanks to all
who responded with suggestions and a willingness to brain storm!

I think turning it off all together is the wrong answer. Just like in OSPF
if
they say never become the DR, they dont mean to turn off OSPF, just set the
priority to 0. They need to rephrase the question because as someone said I
can
always change all the other switches on the lan to the same priority and you
will become root if you now have the lowest mac, so again no guarantee you
wont
be root which is what they are asking you for and thus leaves the question
open.
