第1题:

You are the administrator of a SQL Server 2000 computer in your company's personnel department. Employee data is stored in a SQL Server 2000 database. A portion of the database schema is shown in the exhibit.

You want to create a text file that lists these data columns in the following format title, FirstName, LastName, WorkPhone, PositionName, DepartmentName.

You want to create the text file as quickly as possible. You do not expect to re-create this file, and you want to avoid creating new database objects if possible.

What should you do?

A.Use the bcp utility to export data from each table to a separate text file. Use format files to select the appropriate columns. Merge the data from each text file into a single text file.

B.Create a view that joins data from all three tables include only the columns you want to appear in the text file. Use the bcp utility to export data from the view.

C.Create a SELECT query that joins the data from the appropriate columns in the three tables. Add an INTO clause to the query to create a local temporary table. Use the bcp utility to export data from the local temporary table to a text file.

D.Create a SELECT query that joins the data from the appropriate columns in the three tables. Add an INTO clause to the query to create a global temporary table. Use the bcp utility to export data from the global temporary table to a text file.

第6题:

You are the administrator of a SQL Server 2000 computer. The server contains database named Sales. Users report that they cannot add new data to the database. You examine the properties of the database. The database is configured as shown in the Sales Properties exhibit.

You examine drive E. The hard disk is configured as shown in the Local Disk Properties exhibit.

You want the users to be able to add data, and you want to minimize administrative overhead. What should you do?

A.Increase the maximum file size of Sales_Data to 1,500MB.

B.Use the DBCC SHRINKDATABASE statement.

C.Set automatic file growth to 10 percent.

D.Create another data file named Sales_Data2 in a new SECONDARY filegroup.


正确答案:A
解析:Explanation: By examining the first exhibit we see that the database has reached its maximum size of 1001 MB. The data file is located on drive E and the second exhibit shows us that there is enough free space on that disk to increase the maximum size of the data file to 1,500 MB.

Incorrect Answers:
B: DBCC SHRINKDATABASE could possibly shrink the database and new records could be added for a while, but it would just be a temporary solution.

C: The database is already set to automatic file growth, but it has reached the maximum size.

D: The primary file has reached it maximum size. A secondary filegroup would help if it was set to the default file group. New data would still be added to the primary filegroup which is at its maximum size.
