QUESTION 227
Which two commands display IP Source Guard bindings? (Choose two.)
A. show ip source binding
B. show ip dhcp binding
C. show ip verify source
D. show ip dhcp snooping database
E. show ip guard source
Correct Answer: AC

查看 IP Source Guard 的绑定条目
- 题目问的不严谨，或者答案有问题，应该一个是查看条目，一个是查看配置
- show ip source binding（正确答案）
- show ip verify source （只能查看接口配置）
- show ip dhcp snooping binding (考试如果有这个选项就选他，条目和 show ip source binding 一模一样 )
