Which three statements about VTP features are true?（choose three）
A. When properly configured,VTP minimizes VLAN misconfigurations and configuration inconsistencies
B. Each broadcast domain on a switch can have its own unique VTP domain
C. VTP works at Layer 3 of the OSI model and requires that a management VLAN IP address be
configured.
D. When properly configured,VTP maintains VLAN configuration consistency and accelerates trunk link
negotiation.
E. VTP pruning is used to increase available bandwidth in trunk links
F. Client,server,and transparent are valid VTP modes
G. To configure a switch to be part of two VTP domains,each domain must have its own passwords

主要是D 和G 的解释，为什么不对？

d:解析，说加快trunk链路协议协商 什么意思？

G：主要是一个交换机可以配置多个vtp Domain 吗？怀疑

一台交换机当然可以配置多个VTP啦，交换机是根据domain来区分自己属于那个 区域的。像你数百台交换机的时候，你不可能要求所有交换机都学同样的vlan吧，那就化多个vtp来指定哪些交换机需要学哪些vlan~~

e选项应该说有两条以上trunk 链路的时候，可以分配不同的VLAN走不同的链路，变相增加了可用带宽。
