What’s true about the VLAN trunking protocol (VTP)?

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

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.

Explanation:
VTP messages are only transmitted across trunk links.
If the receiving switch is in transparent mode, the configuration is not changed. Switches in
transparent mode do not participate in VTP. If you make VTP or VLAN configuration
changes on a switch in transparent mode, the changes are not propagated to the other
switches in the network.
Incorrect Answers:
B: The VTP domain name is case sensitive and it must be identical with the domain name
configured on the VTP server.
C: This is incorrect because if a VTP client receives an advertisement with a higher revision
number, it won’t ignore it. In fact, the advertisement with a higher revision level takes
precedence when the switch is configured in client mode.
E: VTP pruning enhances network bandwidth use by reducing unnecessary flooded traffic,
such as broadcast, multicast, unknown, and flooded unicast packets. VTP pruning increases
available bandwidth by restricting flooded traffic to those trunk links that the traffic must use
to access the appropriate network devices. It does not prune the individual VLANs.
