Reveal correct answer
Correct answer: D
Explanation
In Cisco's VLAN Trunking Protocol (VTP), the configuration revision number is a mechanism used to track and manage updates to VLAN information within a VTP domain. Each VTP switch in the domain maintains its configuration revision number, which is a numeric value associated with the VLAN database. When a VTP switch makes changes to its VLAN database, it increments its configuration revision number. During VTP advertisement exchanges, switches compare their configuration revision numbers. If a switch receives a VTP advertisement with a higher configuration revision number than its own, it updates its VLAN database with the new information. This ensures that the VLAN database is consistent across all switches within the domain, preventing inconsistencies and reducing the risk of VLAN misconfigurations. The configuration revision number plays a crucial role in VTP's ability to propagate and synchronize VLAN information across the network efficiently.Discussion
