QUESTION 427
Which statement about access lists that are applied to an interface is true?
A. you can apply multiple access lists with the same protocol or in different…
B. you can config one access list,per direction,per layer 3 protocol
C. you can place as many access lists as you want on any interface
D. you can apply ony one access list on any interface
Answer: D
我感觉这个应该按照题库上的选择,因为访问控制列表和前缀列表都是在最底层用于抓路条目,上层可针对抓到的路由条目做策略!
前缀列表可以更精确的抓路由条目,而ACL可以根据路由信息做筛选,所以说“per layer 3 protocol”可以说的通。
D选项中you can apply ony one access list on any interface的on any interface 说的有些不严谨!
