VLAN Trunking Protocol is a Cisco protocol that propagates the definition of VLANs over the local area network.
Which two statements are true? (Choose two.)
A . When Cisco switches are started from scratch, they are in server mode and their domain is set to null.
B . VTP transparent mode forwards VTP packets and can act as a client or a server.
C . VTP requires trunk mode interfaces to propagate.
D . VTP config revision increases based on switch uptime.
E . VTP requires access mode interfaces to propagate.
Answer: AC
Explanation:
When a new switch is added to the network, by default it is configured with no VTP domain name or password, but in VTP server mode. If no VTP Domain Name has been configured, it assumes the one from the first VTP packet it receives. Since a new switch has a VTP configuration revision of 0, it will accept any revision number as newer and overwrite its VLAN information if the VTP passwords match.
