| What is the purpose of VTP? |
|
Definition
| To make the management of VLANs easier by allowing switches to learn about VLANsfrom each other. |
|
|
Term
| What sort of link between switches is needed to transmit VTP advertisements? |
|
Definition
|
|
Term
| What are the three VTP modes that a switch could take? |
|
Definition
| Server, client and transparent. |
|
|
Term
| What name is given to a group of switches that share VLAN information using VTP? |
|
Definition
|
|
Term
| Which VTP modes allow switches to save VLAN information in the vlan database? |
|
Definition
| Server mode switches store VLAN information for their domain. Transparent modeswitches store information about their own VLANs. |
|
|
Term
| Which VTP versions can be used on a Catalyst 2950 switch, and which is the defaultversion? |
|
Definition
| Versions 1 and 2 can be used. Version 1 is the default. There is a version 3 that can beused on some switches, but no on the Catalyst 2950. |

Term
| How is a VTP domain identified? |
|
Definition
|
|
Term
| Which command is commonly used to display information about VTP? |
|
Definition
|
|
Term
| How is a VTP message encapsulated? |
|
Definition
| It is encapsulated inside an Ethernet frame that is tagged using 802.1Q or ISL. |
|
|
Term
| What destination MAC address is used for VTP messages? |
|
Definition
| The multicast address 01-00-0C-CC-CC-CC |
|
|
Term
| What does a server switch do to the configuration revision number when a new VLAN is added? |
|
Definition
|
|
Term
| What is the purpose of including the configuration revision number in a VTP advertisement? |
|
Definition
| It shows the receiving switch whether the advertisement contains more up to dateinformation than the information that it already has. |
|
|
Term
| Which type of VTP advertisement contains information about VLANs? |
|
Definition
| The subset advertisement. |
|
|
Term
| A transparent switch receives a summary advertisement. What does it do? |
|
Definition
| It will forward the summary advertisement to other switches but ignore its contents. |
|
|
Term
| Which modes of switch will allow you to create new VLANs? |
|
Definition
| Server switches (for the domain) and Transparent switches (for local use only). |
|
|
Term
| Is it possible to have more than one server switch on a domain? |
|
Definition
| Yes. It is a good idea to have more than one server. If there was only one server and it failed, then the VLAN information would be lost. |
|
|
Term
| Is a transparent switch able to obtain VLAN information when it reboots? |
|
Definition
| If the switch has any VLANs configured then they will be saved in the switch’s ownVLAN database, and they will be retrieved. The switch stays in transparent mode(assuming that the configuration has been saved.) |
|
|
Term
| Does any VLAN configuration have to be carried out on a client switch? |
|
Definition
| Switchports need to be assigned to VLANs. This is not done centrally, but is done oneach switch. |
|
|
Term
| What is the effect of giving the vtp pruning command on a server switch? |
|
Definition
| VTP pruning is enabled for the whole domain. VLAN flood traffic will be sent only whereit is needed – in the direction of devices on that VLAN. |
|
|
Term
| What happens to the vtp configuration revision number of a switch if you change its vtp domain name? |
|
Definition
| It is reset to the default value of 0. |
|
|
Term
| Why might you want to change the domain name of a switch temporarily before adding it to an existing VTP domain? |
|
Definition
| If the new switch has a configuration revision number of 0 then there is no danger of thenew switch altering the VLAN information in the VTP domain and updating it with the wrong information. |
|
|
Term
| Which should you do first on a server, configure the VTP domain name or create the VLANs? |
|
Definition
| Configure the domain name first because this will remove existing VLANs. |
|
|
Term
| Which command will make a switch into a VTP client? |
|
Definition
|
|
Term
| If VTP is not working correctly, what should you check? |
|
Definition
| VTP Version. It needs to be the same on all switches in the domain.Domain name. Is it exactly the same on all switches? VTP Password if any. Is it exactly the same on all switches? Check that there is at least one server. Better to have at least two.If you recently added a new switch, had its revision number been set to 0? |
|
|
Term
| Is it possible to have a VTP domain where all the switches are in server mode? |
