QuestionQ1

Ethernet Switching and Spanning Tree

Which three MSTP parameters must be identical on every switch within the same MST region?

Choose three
  • A forwarding delay
  • B bridge priority
  • C revision number
  • D MSTI-to-VLAN mapping
  • E configuration name
Explanation

MST region membership requires switches to use the same MST configuration name, revision number, and MSTI-to-VLAN mapping. These values form the MST configuration identifier used to determine whether switches belong to the same region.
