Which Two Events Will Cause the Vtp Revision Number on a Vtp Server to Change? (Choose Two.)
The VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol that allows for the synchronization of VLAN information across a network. One key aspect of VTP is the revision number, which is used to determine the most recent VLAN database update. The VTP revision number changes under specific circumstances. Let’s explore two events that can cause the VTP revision number on a VTP server to change.
1. Adding, Modifying, or Deleting VLANs: Whenever a VTP server adds, modifies, or deletes VLANs in its database, the revision number increases. This change ensures that all VTP clients receive the updated VLAN information.
2. Promoting a VTP Client to VTP Server: When a VTP client is promoted to a VTP server, it must have a higher revision number than the current VTP server. This change ensures that the newly promoted VTP server has the most recent VLAN information.
FAQs:
1. What happens if the VTP revision number on a VTP server is lower than the VTP client’s revision number?
If the VTP revision number on a VTP server is lower than the VTP client’s revision number, the VTP server will update its VLAN database with the latest information from the VTP client.
2. Can a VTP client modify the VLAN database?
No, a VTP client is not allowed to modify the VLAN database. It can only receive and propagate VLAN information from VTP servers.
3. How does VTP ensure VLAN database consistency across the network?
VTP ensures VLAN database consistency by synchronizing updates across VTP servers. The revision number helps identify the most recent VLAN information.
4. What happens if two VTP servers with the same revision number are connected?
If two VTP servers with the same revision number are connected, the server with the highest VLAN configuration revision number will become the primary server, while the other will become the secondary server.
5. Can VTP pruning affect the revision number?
No, VTP pruning does not affect the revision number. It only helps optimize bandwidth usage by preventing unnecessary VLAN traffic from being sent across trunks.
6. Does the VTP revision number change if a VTP server is removed from the network?
No, removing a VTP server from the network does not change the revision number. The revision number only changes when specific events, such as adding or modifying VLANs, occur.
7. Can the VTP revision number be manually configured?
No, the VTP revision number is automatically managed by the VTP protocol. Manually configuring the revision number can cause inconsistencies and conflicts in the VLAN database.
