NEW QUESTION 43
You made changes to a VLAN, but the changes were not propagated to the other switches in the VTP domain.
You enter a show vtp command at the switch where the changes were made, which displays the following output:
What should you do to solve this problem?
- A. Upgrade the VTP version to version 2.
- B. Upgrade the VTP version to version 3.
- C. Change the VTP operating mode to server.
- D. Disable VTP pruning.
Answer: C
Explanation:
The output of the show vtp command shows that the VTP operating mode is transparent mode. This means that you can make VLAN changes on the switch, but they will only affect that switch. Changes will not be propagated to other switches in the Layer 2 network. You will need to change the operating mode to server if you want to VLAN changes to be propagated to other switches.
To change the VTP operating mode to server, you would enter the vtp server global command as shown:
switch1#(config) vtp server
You should not disable VTP pruning. This will have no effect on the propagation. You must change the mode of the switch.
You should not upgrade the VTP version to version 2 or version 3. This will have no effect on the propagation.
You must change the mode of the switch.
Objective:
Layer 2 Technologies
Sub-Objective:
Configure and verify trunking
