第8题：

用标准访问控制列表配置只允许212.33.127.0/24子网主机登录到路由表，正确的配置是______。

A．Router(config) #access-list 10 permit 212.33.127.0 255.255.255.0 Router(config) #line vty 0 5 Router(config-line) #access-class 10 in

B．Router(config) #access-list 20 permit 212.33.127.0 0.0.0.255 Router(config) #line vty 0 5 Router(config-line) #access-class 20 out

C．Router(config) #access-list 99 permit 212.33.127.0 0.0.0.255 Router(config) #line vty 0 5 Router(config-line) #access-class 99 in

正确答案：C
解析：表号1～99用于标准访问控制列表，扩展访问控制列表的表号范围为100～199和2000～2699，D项不符合，并且通配符用32位二进制数表示，表示形式与IP地址和子网掩码相同，实际上就是子网掩码的反码，212.33.127.0/24的子网掩码为255.255.255.0，反码为0.0.0.255。因此选C。
