Using Automatic Private IP Addressing
The Windows 2000 implementation of TCP/IP supports a new mechanism for automatic address assignment of IP addresses for simple LAN-based network configurations. This addressing mechanism is an extension of dynamic IP address assignment for LAN adapters, enabling configuration of IP addresses without using static IP address assignment or installing the DHCP Service.

For the Automatic Private IP Addressing (APIPA) feature to function properly on a computer running Windows 2000, you must configure a network LAN adapter for TCP/IP and click Obtain An IP Address Automatically in the Internet Protocol (TCP/IP) Properties dialog box.

The following steps outline how APIPA assigns an IP address:

Windows 2000 TCP/IP attempts to find a DHCP server on the attached network to obtain a dynamically assigned IP address.

In the absence of a DHCP server during startup (for example, if the server is down for maintenance or repairs), the client cannot obtain an IP address.

APIPA generates an IP address in the form of 169.254.x.y (where x.y is the client's unique identifier) and a subnet mask of 255.255.0.0. If the address is in use, APIPA selects another IP address and, if necessary, reselects addresses up to 10 times.

Windows 2000 Server 推荐的最小内存数量为多少？

解答：

　　这是一道非常容易让人出错的题目，容易出错的地方就在于不是问你系统支持的最小内存的数量，而是问推荐的最小内存数量，所以，很多人往往会选择128，而这就正中了考题的圈套了，所以说，国外的职业 资格 认证考试表面看起来似乎很板，不会玩什么花样，实际上却一直都在跟你斗心眼，千万要注意呀！

正确答案：B

在这里有一个迷惑人的地方，Training Kit 写的是推荐 网络 中最低128MB内存， 微软 官方公布的是：Windows 2000 Server 的需求条件，内存，推荐为最低256MB(也支持128MB)，对于这点，经过确认，确实应该以官方公布为准，考生需要特别注意此点。
