Refer to the exhibit.
The network operations center has received a call stating that users in VLAN 107 are unable
to access resources through router 1. What is the cause of this problem?
A.
VLAN 107 does not exist on switch A.
B.
VTP is pruning VLAN 107.
C.
VLAN 107 is not configured on the trunk.
D.
Spanning tree is not enabled on VLAN 107.
Explanation:
In this example, VLAN 7, 101, 106, and 107 are being pruned. VLAN 107 is being pruned
incorrectly in this case. By disabling VTP pruning, VLAN 107 should be able to once again
gain access to the network resources.
