5. 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.
Answer: CEF
