问题 What will happen if a private IP address is assigned to a public interface connected to an ISP?
选项 A、        Addresses in a private range will be not routed on the Internet backbone．
B、        Only the ISP router will have the capability to access the public network．
C、        The NAT process will be used to translate this address in a valid IP address．
D、        Several automated methods will be necessary on the private network．
E、        A conflict of IP addresses happens, because other public routers can use the same range．
答案A
解析 私有地址被分配到连接到ISP的公网端口上，将会发生什么？
内部网络使用了私有地址，如果不使用nat的话我们是没办法访问外部网络的。因为公共网络不会给私有地址路由
