In a customer’s network， VLAN Trunking Protocol （VTP） is running with a domain named main1. VLANs 1，2，3，4，5，10，20 are active on the network. Suddenly the whole network goes down. No traffic is being passed on VLANs 2，3，4，5，10，20， however traffic passes on VLAN 1 and indicates all switches are operational. Right before the network problem occurred， a switch named TEST1 was added to the network.
What three configuration issues on TEST1 could be causing the network outage？（）
A.TEST1 is configured as a VTP server with a different domain name.
B.TEST1 is not configured to participate in VTP.
C.TEST1 is configured as a VTP server with the domain name main1.
D.TEST1 has a lower VTP configuration revision than the current VTP revision.
E.TEST1 has a higher VTP configuration revision than the current VTP revision.
F.TEST1 is configured with only VLAN1.
