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.

答案：B

文中不是说Not Prun吗？为什么选B

如果SWITCHA上没有VLAN107的流量就会被修剪的。这个VLAN被SPANNING-TREE给BLOCK了

比较一下输出信息，可用的里面有107，spanning-tree里面没有107，就是说被剪了。
