  • 第1题：

    要禁止内网中IP地址为198.168.46.8的PC访问外网，正确的ACL规则是(11)。

    A．access-list 1 permit ip 192.168.46.00.0.0.255 any access-list 1 deny ip host 198.168.46.8 any

    B．access-list 1 permit ip host 198.168.46.8 any access-list 1 deny ip 192.168.46.00.0.0.255 any

    C．access-list 1 deny ip 192.168.46.00.0.0.255 any access-list 1 permit ip host 198.168.46.8 any

    D．access-list 1 deny ip host 198.168.46.8 any access-list 1 permitip 192.168.46.00.0.0.255 any


    正确答案：D
    D 解析：这是一道要求掌握标准访问控制列表的具体应用的理解题。本题的解答思路如下。
    最简单的访问控制列表就是标准访问控制列表。它是通过使用IP包中的源IP地址进行过滤，使用访问控制列表号1～99宋创建相应的ACL。其具体的语法格式如下：

    例如，access-list 1 deny ip host 198.168.46.8 any配置语句可将所有来自198.168.46.8地址的数据包丢弃。对于标准访问控制列表而言，可以省略默认的关键词host。换言之，语句access-list 1 deny ip host 198.168.46.8 any与语句access-list 1deny中198.168.46.8 any是等价的。
    当然也可以用网段来表示ip地址＞，以实现对某个网段的数据包的过滤。例如，access-list 1 permit ip 192.168.46.00.0.0.255 any配置语句，允许所有来自198.168.46.0/24网段内所有计算机的数据包通过防火墙。其中，0.0.0.255是子网掩码255.255.255.0的反向掩码。

    正确答案：(5) B
    (5) B 解析：访问控制列表(ACL)用于过滤流入和流出路由器接口的数据包。它是一种基于接口的控制列表，可根据网络管理员制定的访问控制准则来控制接口对数据包的接收和拒绝，从而提高网络的安全性。
    IP访问控制列表是一个连续的列表，至少由一个“permit(允许)”语句和一个或多个“deny(拒绝)”语句组成。ACL列表用名字(name)或表号(number)标识和引用。配置IP访问控制列表的首要任务就是使用命令“access-list”定义一个访问控制列表。在配置过滤规则时，需要注意的是ACL语句的顺序。因为路由器接口执行哪一条ACL是按照配置的访问控制列表中的条件语句(准则)，从第1条开始按顺序执行的。数据包只有在跟前一个判断条件不匹配时，才能跟交给ACL的下一个条件语句进行比较。可见，ACL语句的先后顺序非常重要。例如，只封禁一台地址为192.168.1.230的主机的access-list正确配置示例如下：
    access-list 110 deny ip host 192.168.1.230 any
    access-list 110 deny ip any host192.168.1.230
    access-list 110 permit ip any any
    如果将“access-list 110 permit ip any any”放在ACL规则的最前面(见选项A)，则其后两条deny语句将不起作用，即不能按照预期的应用需求正确地控制数据包的接收与拒绝。
    选项C的ACL规则中，缺少“permit(允许)”语句，它将封禁全网所有的通信。
    选项D的ACL规则将封禁地址为192.168.1.230的主机对外的单向通信，允许其他主机或路由器访问 192.168.1.230的主机。
