Refer to the exhibit.
The company wants to use MSTP to handle loop suppression and Layer 2 resiliency. Which
design should the network architect recommend to meet this requirement?
A.
Establish a different MSTP region in each distribution segment. Use the Common and Internal
Spanning Tree (CIST) across the core and between distribution segments.
B.
Route traffic at the distribution layer. Establish different MSTP regions, each of which uses a
different pair of distribution switches as the redundant root bridges.
C.
Extend the MSTP region across the topology. Use the core switches as redundant root bridges
for the IST. Use each pair of distribution switches as redundant root bridges for a different
instance.
D.
Extend the MSTP region across the topology. Use the core switches as redundant root bridges
for all instances in the region,
Answer is B.
Taken from the Study Guide:
“If you are working with a three-tier topology, implement routing at the distribution layer. The pair of distribution switches then acts as the MSTP Root.”

Only B. You should minimize STP domain as much as possible. Distr-Core must route traffic, not switch
