Refer to the exhibit. The VLAN-to-MST mapping is shown. (Assume SW1 acts as root for all possible MST instances.)
spanning-tree mst configuration name MST?
revision 2?
instance 0 vlan 1-200,301-4094 instance 1 vlan 201-300
!
If this topology is deployed, which action is required for traffic to flow on VLAN 200 and 300?
A. Map VLAN 300 to instance 0.
B. Map VLAN 200 to instance 2.
C. Move instance 0 root to SW2.
D. Move instance 1 root to SW2.
E. Map both VLANs to instance 2.
Instance 0 is treated different than other instances.. referred to as “IST”

Can someone explain me this question? if the goal is to have vlan 200 and 300 on separate links, the correct answer is D (or C… it is the same). creating a new instance 2 will not help (it will be rooted at SW1 like the others)
