Answer: C

Explanation:

By default, a switch will have a domain name of NULL and no password. If the switch hears a VTP advertisement it will automatically learn the VTP domain name, VLANs, and the configuration revision number. Summary advertisements sent out every 300 seconds and every time a change occurs on the VLAN database.

Contained in a summary advertisement:

VTP version

Domain name

Configuration revision number

Time stamp
