After configuring new data VLANs 1020 through 1030 on the VTP server, a network engineer notices that none of the VTP clients are receiving the updates. What is the problem?

A. The VTP server must be reloaded.

B. The VTP version number must be set to version 3.

C. After each update to the VTP server, it takes up to 4 hours propagate.

D. VTP must be stopped and restarted on the server.

E. Another switch in the domain has a higher revision number than the server.






 

Suggested Answer: B

VTP version 3 supports these features that are not supported in version 1 or version 2:
✑ Enhanced authenticationYou can configure the authentication as hidden or secret. When hidden, the secret key from the password string is saved in the
VLAN database file, but it does not appear in plain text in the configuration. Instead, the key associated with the password is saved in hexadecimal format in the running configuration. You must reenter the password if you enter a takeover command in the domain. When you enter the secret keyword, you can directly configure the password secret key.
✑ Support for extended range VLAN (VLANs 1006 to 4094) database propagation. VTP versions 1 and 2 propagate only VLANs 1 to 1005. If extended
VLANs are configured, you cannot convert from VTP version 3 to version 1 or 2.
