  • 第1题:

    随着Internet迅速发展,公网IP地址短缺已成为一个十分突出的问题。为了解决这一问题,出现了多种解决方案。而使用路由器的NAT/NAPT(Network Address Translation/Network Address Port Translation)功能是其中一种解决方法。

    如图5-1所示,某企业通过租用ISP的线路(获得的公网IP网段为:218.94.86.0/29,除去两个互联的IP地址),实现企业的电子商务。其中,有一对外的Web服务器(内网IP地址为192.168.0.100/24),一OA服务器(内网IP地址为192.168.0.101/24)。

    以下是本端路由器的配置摘要,请解释其中部分语句的含义(“//”后为注释内容)。

    version 11.2 //版本

    !

    hostname RouterCOM //路由器名称

    !

    interface Seria10 //串口0

    ip address 218.94.86.2 255.255.255.248 //串口0的ip地址

    ip nat outside (1)

    !

    interface FastEthernet 0 //快速以太口0

    ip address 192.168.0.1 255.255.255.0 //快速以太口0的ip地址

    ip nat inside (2)

    !

    access-list 1 permit 192.168.0.0 0.0.0.255 (3)

    !

    ip nat pool natpool 218.94.86.5 218.94.86.6 netmask 255.255.255.248

    (4)

    ip nat inside source static 192.168.0.100 218.94.86.3 (5)

    ip nat inside source statiC 192.168.0.101 218.94.86.4

    ip nat inside source list 1 pool natpool overload (6)

    ……(略)

    end

  • 第3题:

    The number of home users and small businesses that want to use the Internet is ever increasing. The shortage of addresses is becoming a serious problem. A quick solution to this problem is called network address translation(NAT).NAT enables a user to have a large set of addresses( )and one address, or a smallset of addresses,externally. The traffic inside can use the large set; the traffic( ), the small set. To separate the addresses used inside the home or business and the ones used for the Internet, the Internet authorities have reserved three sets of addresses as ( ) addresses. Any organization can use an address out of this set withoutpermission from the Internet authorities. Everyone knows that these reserved addresses are for private networks.They are ( ) inside the organization, but they are not unique globally. No router will (请作答此空) a packet that has one of these addresses as the destination address.The site must have only one single connection to the global Internet through a router that runs the NAT software.

    A.reject
    B.receive
    C.deny
    D.forward
