QUESTION 614
1 s/ Q- T5 e; aWhich two commands display the VLANs that are present in the VLAN database? (Choose two.)
A. show running-config
B. show vlan database
C. show vlan brief
D. show vlan
8 n- ~5 I. B* w$ {2 lE. show vlan id
Correct Answer: AD


  Z2 ~8 {# r1 r: v我觉得应该选C 和 D， 因为show running-config 只能包含 vtp transparent模式下的VLAN信息， 其他模式是不包含在running-config里的。
另外show vlan brief是可以显示所有VLAN信息的， 只是没有详细信息。

感谢您的回复。

题目是： display the VLANs， 我觉得没有问到VLAN的具体信息。

4 [! e8 g) J2 @2 W况且如果不是transparent模式的话，show run是看不到vlan信息的。
