CCIE Data Center (legacy) — Question 83

Which statement about VTP bombing is true?

Answer options

• A. It occurs because of configuration mismatch on VTPv3 switches. This problem can be avoided using a confirmation management tool.
• B. It occurs when switches with different VTP versions are connected together. This situation may occur when a new switch is plugged into a stable VTP domain. The MAC address table of the new switch overrides the MAC address table of stable switches causing interruption of service.
• C. It occurs when a client connects to a switch and launches a distributed denial of service attack against the VTP domain. This attack is possible only ifthe client knows the VTP password.
• D. It occurs when a server with a higher revision number and a wrong VTP database is inserted into the VTP domain. This situation may occur when a new switch plugged into a stable VTP domain. The incorrect database is propagated to the domain and the earlier stable database is overwritten. D

Correct answer:

Explanation

The correct answer is D, as VTP bombing involves the introduction of a switch with a higher revision number that has a flawed VTP database, which then overwrites the existing stable database in the domain. Options A and C describe unrelated scenarios, while B incorrectly attributes the issue to different VTP versions rather than focusing on the revision number and database integrity.
