Refer to the exhibit. Switch A is connected to two MSTP domains for the first time.
This error is observed on Switch A.
%SPANTREE-2-PVSTSIM_FAIL:
Blocking designated port Fa0/1:
Inconsistent superior PVST BPDU received on VLAN 10
How can this error be resolved?
A. Map VLAN 10 into an appropriate instance on Switch A.
B. Remove the 1ST root from MST Region 2.
C. Configure PVST+ to allow MST Region 1 to the root for VLAN 10.
D. Map VLAN 10 to instance 0 in all MST regions.
probably it was reported incorrectly, and the image is useless, but https://community.cisco.com/t5/switching/mst-with-a-pvst-cst-root/td-p/1228551 says that, in cisco implementation, the root MUST be within the MST region, so I’d answer C
THere’s no way to understand this question
