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

C.
TEST1 is not configured to participate in VTP.

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

E.
TEST1 is configured with only VLAN1.

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