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？（）

TEST1 is configured as a VTP server with a different domain name.

TEST1 is not configured to participate in VTP.

TEST1 is configured as a VTP server with the domain name main1.

TEST1 has a lower VTP configuration revision than the current VTP revision.

TEST1 has a higher VTP configuration revision than the current VTP revision.

TEST1 is configured with only VLAN1.
