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.

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.
