Basic STP question

Hi

Please see my attached my network diagram.

Switch 1 is my root bridge for vlans 50, 100 and 200 with spanning tree priority of 0 for all vlans.
I’m running rapid stp on all my three cisco switches.

Between switch 1 and 2 all vlans are allowed over trunk
Between switch 2 and 3 all vlans are allowed over trunk except for vlan 100. This will cause switch 1 to be Root Bridge for vlan 100 and on switch 3 vlan 100 will be root bridge.

Please advise if this is correct.

That is correct.  

I'm assuming this is a theoretical question since in this case switch 3 probably wouldn't have a vlan 100 configured on it.
