Originally introduced by Netscape Communications,(1)are a general mechanism which HTFP Server side applications, such as CGI(2), can use to both store and retrieve information on the HTTP(3)side of the connection. Basically, Cookies can be used to compensate for the(4)nature of HTTP. The addition of a simple, persistent, client-side state significantly extends the capabilities of WWW-based(5).

第1题：
You are the administrator of several SQL Server 2000 computers. You want to retrieve information from an archived inventory database. You have a full tape backup of the database. The backup’s header information shows that the backup uses the SQL_Latin1_General_CR437_BIN collation.
However, the existing SQL server computers in your office are configured to use the
SQL_Latin1_General_CP1_CI_AS collation.
You do not want to join tables in the inventory database with tables in other databases. You need to restore the inventory database to a SQL Server 2000 computer by using the least amount of administrative effort.
What should you do?
A．Use the rebuildm utility to rebuild the system database on an existing SQL server computer. Configure all the databases on that server to use the SQL_Latin1_General_CR437_BIN collation. Restore the inventory database to the server.
B．Restore the inventory database to an existing SQL server computer. Accept the SQL_Latin1_General_CR437_BIN collation for that database.
C．Install a new named instance of SQL Server 2000 on an existing SQL Server 2000 computer. Configure the named instance to use the SQL_Latin1_General_CR437_BIN collation. Restore the inventory database to the named instance.
D．Install SQL Server 2000 on a new computer. Configure the new server to use the SQL_Latin1_General_CR437_BIN collation. Restore the inventory database to the new server.

第2题：
［A］creatively ［B］originally ［C］authentically ［D］initially
正确答案：A本题考查通过上下文选择适当的副词的能力。空格处的副词修饰的动作是use real-estate assets in and around train stations（利用车站内部及周围的房地产）。由上下文可知，该举动是有创造性的，所以才会引起人们的关注，因此［A］项creatively“创造性地”正确。originally“最初，原先 ，新颖地”,如The apartment was decorated quite originally（这套公寓装饰的十分别致）；authentically“确实地，真正地，逼真地”，其形容词形式为authentic，如 DiMaggio was an authentic folk hero（迪马乔是一位真正的民间英雄）；initially“最初，开头”，如His response was initially adamant（他的反应开始很强硬）。

第4题：
You are the database administrator for an accounting company. You are installing SQL Server 2000 on a new Microsoft Windows 2000 Server computer. The computer will run two client/server database applications that your company has purchased. Each application uses a separate database.
During the installation, you specify SQL_Latin1_General_CP1_CI_AI as the default collation for the SQL server computer. After completing the installation, you discover that one of the new applications, named Financials, is sorting information incorrectly.
You contact the application vendor and discover that the Financials application requires the SQL_Latin1_CP437_BIN collation. You need to configure the correct collation for the applications without diminishing the performance of the SQL Server computer.
What should you do?
A．Rerun the SQL Server Setup and specify the SQL_Latin1_General_CP437_BIN collation.
B．Run the rebuildm utility and specify the SQL_Latin1_General_CP437_BIN collation.
C．Use the ALTER DATABASE statement to specify the SQL_Latin1_General_CP437_BIN collation for the Financials database.
D．Use the ALTER TABLE statement to specify the SQL_Latin1_General_CP437_BIN collation for each table in the Financials database.
