题目如下：

题库里说选c。但是SW2的vtp operation mode是client啊。也就E勉强算对吧。

求解...

虽然似乎client, 但当它启动时，会发送一次汇总信息。Server是会接受，如果这个汇总信息有更高的Revision Number.
在书 （ccnp switch 642-813 Official Certification Guide）英文版中有写到：
It might seem intuitive that a switch acting as a VTP server could come online with
a higher configuration revision number and wreak havoc on the whole domain. You should
also be aware that this same thing can happen if a VTP client comes online with a higher
revision, too!
Even though it seems as if a client should strictly listen to advertisements from servers, a
client can and does send out its own advertisements. When it first powers up, a client sends
a summary advertisement from its own stored database. It realizes that it has a greater revision
number if it receives an inferior advertisement from a server. Therefore, it sends out a
subset advertisement with the greater revision number, which VTP servers will accept as
more up-to-date information.
