QUESTION 59
Refer to the exhibit. Which statement describes the effect that the Router1 configuration has on devices in
the 172.16.16.0 subnet when they try to connect to SVR-A using Telnet or SSH?
A. Devices will not be able to use Telnet or SSH.
B. Devices will be able to use SSH, but not Telnet.
C. Devices will be able to use Telnet, but not SSH.
D. Devices will be able to use Telnet and SSH.
Answer: B
Explanation/Reference:
题目考查的是ACL用法,首先我们看图示
要控制的是172网段 也就是F0/0 是in方向
f0/1 应该是out方向 也就是从左到右的数据
通过此图 我们看出list 100 为fa0/0的in方向
而list101 是f0/1的in方向 所以对172网段不会生效
生效的是list 100
我们只要看list 100 就可以选出答案 可以SSH
而20格式不正确,应该将eq放在目的地址后面才会起作用。所以可以SSH但是不能telnet 这句话有点不能理解 希望高手解答。。。
