Sure, it definitely has drawbacks, but remember that the lab is not real
life.. you are there to "meet the requirements". Don't overthink things,
just do what is asked...

But doesn't turning it off has its own drawbacks???

A Priority of 0 is considered better (higher priority) than 1 and will most
likely take over root priority...
To give a switch the "worst" possible chance of becoming root, set priority
to 65535 for that vlan...
To "ensure" that the switch "never" becomes root, turn off spanning tree for
that vlan....
Just my thoughts..

That might work but if another switch gets added to the STP domain and
your switch has a lower mac-address then it will become the root bridge
assuming that the priority is 65535. I thought I read somewhere that
using 0 will make sure that it will never become a root bridge.

Larry,
I would suggest making the bridge priority 65535, the highest possible
value.
Good luck!
