7. 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? (choose three.)

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.
