JN0-649 Exam - Question 33


Which three MSTP parameters must match on all switches in the same MST region? (Choose three.)

Show Answer
Correct Answer: CDE

The three MSTP parameters that must match on all switches in the same MST region are the revision number, MSTI-to-VLAN mapping, and configuration name. The revision number identifies the version of the MST configuration and must be consistent across all switches in the region. The MSTI-to-VLAN mapping ensures that all switches map VLANs to MST instances in the same way, maintaining a consistent view of the network topology. The configuration name is a user-defined name that identifies the MST region, and it must be the same on all switches within the region to ensure they are part of the same MST region.

C,D,E is correct: The three MSTP parameters that must match on all switches in the same MST region are: MST Configuration Name: This is a user-defined name that identifies the MST region. All switches in the same region must have the same configuration name. MST Configuration Revision: This is a numeric value that identifies the version of the MST configuration. All switches in the same region must have the same revision number. VLAN-to-Instance Mapping: This is a mapping of VLANs to MST instances. All switches in the same region must have the same VLAN-to-instance mapping. These parameters ensure that all switches in the MST region have a consistent view of the network topology and prevent loops and other configuration inconsistencies.
