Correct Answer: DE
For switches within the same MST (Multiple Spanning Tree) region, they must have the same MST configuration revision number, which identifies and tracks changes to the MST configuration. Additionally, they must have the same VLAN-to-instance mapping, which dictates how VLANs are assigned to different spanning tree instances within the MST region. These two configurations are essential to maintain consistency and proper functioning of MSTP in the network.

May 11, 2023Disregard A because the question states the regions match D/E: MST configuration name - This is a user-defined name that identifies the MST region. All switches in the same MST region must have the same configuration name. MST configuration revision number - This number is used to track changes made to the MST configuration. All switches in the same MST region must have the same configuration revision number. VLAN-to-instance mapping - MST maps VLANs to instances.
