The Company switches are configured to use VTP. What’s true about the VLAN trunking protocol  （VTP）？（）
A

VTP messages will not be forwarded over nontrunk links.

B

VTP domain names need to be identical. However，case doesn’t matter.

C

A VTP enabled device which receives multiple advertisements will ignore advertisements with higher configuration revision numbers.

D

A device in transparent VTP v.1 mode will not forward VTP messages.

E

VTP pruning allows switches to prune VLANs that do not have any active ports associated with  them.
