Which two statements about VTP are true? (Choose two.)
A. All switches must be configured with the same VTP domain name
B. All switches must be configured to perform trunk negotiation.
C. All switches must be configured with a unique VTP domain name
D. The VTP server must have the highest revision number in the domain
E. All switches must use the same VTP version.
A, D and E are all correct according to Cisco.

VTP Configuration Guidelines
This section provides some guidelines for the configuration of VTP in the network.
All switches have the same the VTP domain name, unless the network design insists for different VTP domains.
Note: Trunk negotiation does not work across VTP domains. Refer to the Data Traffic Blocked between VTP Domains section of Troubleshooting VLAN Trunk Protocol (VTP) for more information.
All switches in a VTP domain must run the same VTP version.
All switches in a VTP domain has the same VTP password, if there is any.
All VTP Server switch(es) should have the same configuration revision number and it should also be the highest in the domain.
When you move a VTP mode of a switch from Transparent to Server, VLANs configured on the VTP Transparent switch should exist on the Server switch.
Cisco says that all switches in a VTP domain must run the same VTP version, but the question and answer “E” don’t mention domain.
Cisco also says all VTP Server switch(es) should have the same configuration revision number and it should also be the highest in the domain.
So to me it looks like the correct answer is A & D
A and E
The VTP versions can be different. The switches will send updates based on teh version they are connect to. Higher can go lower but lower versions cna not go higher
E : is incorrect, Switches running in transparent ignore VTP updates.
They are talking about Software update not switching updates…
I think E is also true.
