问题 Refer to the exhibit． The show vtp status command is executed at a switch that is generating the exhibited output． Which statement is true for this switch?
选项 A、The switch forwards its VLAN database to other switches in the ICND VTP domain．
B、The configuration revision number increments each time the VLAN database is updated．
C、The switch forwards VTP updates that are sent by other switches in the ICND domain．
D、The VLAN database is updated when VTP information is received from other switches．
答案C
解析 VTP是为了动态学习和同步VLAN信息的，但是他的同步和学习都是以域为单位的，只有同一个域中的VLAN信息才可以同步和学习。而VTP的模式有三种：server , client , transparent。其中transparent模式为通明桥的模式，在这种模式下的VLAN的信息是不能被其他设备学习到的，而切这种模式下的设备也不学习其他设备的VLAN信息，他只是转发VLAN的信息，但是不学习。
