QUESTION NO: 118
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.

QUESTION NO: 120
A switch that is to be added to the production network has been preconfigured (trunks, VLANs, VTP, and STP) and was tested in your lab. After installing the switch into the network, the entire network went down. What might explain what happened?
A. The new switch happened to be running Cisco Catalyst operating system, while the other network switches were running Cisco IOS Software.
B. The configuration revision of the new switch was higher than the configuration revision of the production VTP domain.
C. The link costs on the new switch are set to a high value, causing all ports on the new switch to go into a forwarding mode and none into blocking mode, thereby causing a spanning-tree loop.
D. The ports connecting to the two switches have been configured incorrectly. One side has the command switchport mode access and the other switchport mode trunk.
Answer: B
