VTP Interview Questions and Answers
VTP Interview Questions and Answers
The vtp protocol is a fairly complex protocol, but easy to understand and implement once you get to know it. Currently, 3 different versions of the protocol exist, that is, version 1, 2 (adds support for token ring networks) and 3, with the first version being used in most networks.
Despite the variety of versions, it also operates in 3 different modes: server, client and transparent mode, giving us maximum flexibility on how changes in the network effect the rest of our switches. To help keep things simple and in order to avoid confusion, we will work with the first version of the vtp protocol - vtp v1, covering more than 90% of networks.
Below you'll find the 3 modes the vtp protocol can operate on any switch throughout the network:
Vtp server mode
Vtp client mode
Vtp transparent mode
You can delete a specific vlan or all vlans that are configured on a network interface. When you delete all vlans on an interface, the interface is then available to be configured as a regular physical interface.
3. What is the difference between vtp transparent and vtp client mode ?
All server and client switches in the same vtp domain will use the vlan database with the highest revision number. ... Vtp transparent mode, maintains its own vlan definitions in its config file. Vtp transparent mode, though, can pass a vlan database through it, although it doesn't use it itself.
4. Which is the default mode of vtp ?
Server mode
5. What is vtp pruning ?
Vlan trunking protocol (vtp) is used to communicate vlan information between switches in the same vtp domain. Vlan trunking protocol (vtp) pruning is a feature in cisco switches, which stops vlan update information traffic from being sent down trunk links if the updates are not needed.
6. What are two benefits of using vtp in a switching environment?
It maintains vlan consistency across a switched network.
It allows frames from multiple vlans to use a single interface.
It allows vlan information to be automatically propagated throughout the switching environment. ... One of the two switches must be configured as a vtp server.
7. Which vtp mode is capable of creating only local vlans and does not synchronize with other switches in the vtp domain?
7. Which vtp mode is capable of creating only local vlans and does not synchronize with other switches in the vtp domain?
Transparent
