This have been discussed a few times before on this list.
The two options are the two you have listed. The first is I believe the
answer they are looking for although it does not guarantee 100% that the cat
will not become the root. The other option is not a very smart move although
a lot of the things we do in these labs are not very smart.
The best answer is ask the proctor if you get something like this in the
actual lab. If it's not the real lab then it doesn't matter which option you
take as long as you know both options and the pros/cons of each one.

Hi,
Please help me with the answer for this question: Ensure that a Catalyst
5000 switch never becomes the root bridge for a given vlan.
I see two possible answers because I find the question ambiguous. Does it
mean 'the vlan can still run spanning tree without ever becoming the root',
or 'the vlan does will no longer run spanning tree'?
1. Set the spantree bridge-priority for the vlan to the highest possible
value.
!
set spantree priority 65535 <vlan#>
!
2. Disable spantree altogether for the vlan.
!
set spantree disable <vlan#>
!
Thanks.
