Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 189

A new network that consists of several switches has been connected together via trunking interfaces. If all switches currently have the default VTP domain name
"null", which statement describes what happens when a domain name is configured on one of the switches?

Answer options

• A. The switch with the non-default domain name restores back to "null" upon reboot.
• B. Switches with higher revision numbers does not accept the new domain name.
• C. VTP summary advertisements are sent out of all ports with the new domain name.
• D. All other switches with the default domain name become VTP clients.

Correct answer:

Explanation

The correct answer is C because when a new VTP domain name is configured, VTP summary advertisements containing this new name are sent out to inform other switches. Option A is incorrect as the switch does not revert back to 'null' upon reboot. Option B is wrong because switches with higher revision numbers can still accept changes if they fall below the current revision. Option D is incorrect because switches with the default domain name do not automatically become VTP clients; they remain in their current state unless configured otherwise.
