Which of the following statements is true regarding the MST configuration revision number?

The statement that the MST configuration revision number can be any number as long as it matches on all switches is accurate. In the Multiple Spanning Tree (MST) protocol, the revision number plays a crucial role in determining the active configuration across the switches in a network. Each instance of MST is identified by its configuration revision number alongside the MST configuration name.

When switches share the same MST configuration name and revision number, they recognize each other’s configurations as valid and can effectively communicate within the same spanning tree. If the revision number differs across switches, it may lead to inconsistent spanning tree topology, which can cause unwanted network behavior like loops or failures.

The other statements contain inaccuracies: it is not limited to a range from 1 to 10, it is not intended to remain constant if changes occur, and it is not specific to each VLAN but rather to the overall MST region. Understanding that the revision number must be consistent across all switches is essential in maintaining a stable and correctly functioning MST environment.
