<P>what is the VTP function of this particularswitch?</P><P>这题是考察VTP的各种模式(服务端 客户端 透传)的功能。并考察了一些交换机的常识!</P><P>Server Mode:创建,修改,删除,接收(即学习和保存)VLAN信息.</P><P>Client Mode:接收VLAN信息.不能创建,修改,删除VLAN信息,存放在哪要看交换机型号。</P><P>Transparent:作为中继,透明地传输VLAN信息,自己不参与进去。</P><P>题中有VTP Operating Mode: Client 表明它了它的模式,因此只能学习和保存。</P><P>题中还有<FONT color=#3809f7>Maximum VLANs supported locally: 64</FONT> 可见它是Catalyst1900的交换机,因此runningconfig=startconfig,A答案用到save VTP configuration in the running configuration.</P><P>E答案VTP is not saved to NVRAM是错的,因为<FONT color=#3300ff>1900交换机只有NVRAM,它的runningconfig就保存在NVRAM中</FONT>,这是一个交换机常识。其他有些交换机就不是保存在NVRAM中了。</P><P>B答案是典型的Server mode的功能;C答案是Transparent mode的功能;D答案是由于题中提到VTP Pruning Mode: Disabled<BR>VTP V2 Mode: Disabled<BR>VTP Traps Generation: Disabled,而来混淆选题者,VTP协议默认总是开着的!<BR><BR></P>
