Sub-Objective: Configure, verify and troubleshoot VTP

Multiple Answer, Multiple Choice

Which of the following statements correctly identify the guidelines for configuring VLAN Trunking Protocol (VTP) in a network? (Choose three.)

1. The VTP version must be the same on all switches in a VTP domain.
2. The configuration revision number must be the same on all switches in a VTP domain.
3. The VTP password must be the same on all switches in a VTP domain.
4. The VTP domain name must be the same on all switches in a VTP domain.
5. VLANs configured on clients should exist on the server switch.

Answer:
A. The VTP version must be the same on all switches in a VTP domain.
C. The VTP password must be the same on all switches in a VTP domain.
D. The VTP domain name must be the same on all switches in a VTP domain.

Tutorial:
VTP protocol is used to manage Virtual Local Area Networks (VLANs). VTP can be used to add, delete, modify or rename VLANs on a network. The following are the guidelines that should be followed to configure VTP in the network:

• The VTP version must be the same on all switches in a VTP domain.
• The VTP password must be the same on all switches in a VTP domain.
• The VTP domain name must be the same on all switches in a VTP domain.
• The configuration revision number must be the same on all VTP server switches.
• VLANs configured on the VTP transparent switch should exist on the server switch.

The option stating that the configuration revision number must be the same on all switches in a VTP domain is incorrect. The configuration revision number must be the same on all VTP server switches.

The option stating that VLANs configured on clients should exist on the server switch is incorrect. VLANs configured on the VTP transparent switch should exist on the server switch.
