  • 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13题：

    You are the administrator of a SQL Server 2000 computer. The server contains a database named Acct. You purge the Acct database of old records and perform. a full backup. The database now uses 4 GB of space. The database files are configured as shown in the Acct Properties exhibit.

    The server has two hard disks that are configured as shown in the Server Configuration exhibit.

    The 3 GB transaction log file for the Acct database is stored on drive C. You need to make room for a new database that has a 3 GB data file and a 1 GB transaction log file. You want to optimize database performance on both databases. You also want to minimize administrative overhead.

    What should you do?

    A．Shrink the empty data file on drive E. Place the new data file and the new log file on drive E.

    B．Shrink the empty data file on drive E. Backup and shrink the log file on drive C to 2 GB. Place the new data file on drive E and the new log file on drive C.

    C．Shrink the data file on drive D to 1 GB, and then shrink the data file on drive E to 2 GB. Place the new data file on drive D and the new log file on drive E.

    D．Shrink and delete the data file on drive C, and then shrink the database files on drives D and E so that they are both 2 GB. Place the new data file and the new log file on drive C.


    正确答案：B
    解析：Explanation: We must add a new 3GB database with a 1GB transaction log file. Currently we have database that is using 4GB for data and 3GB for the log file. We should place the log file and the data file on two different physical disks out of performance reasons.

    The command DBCC SHRINKFILE with the EMPTYFILE option can be used to shrink a datafile to empty. The data will be migrated to the other files in the filegroup. We use this method to free 4.5 GB on Drive E. Then we backup the log file on C and reduce it to 2GB. Then we put the database data file on drive (3GB) and put the log file of the new database on drive C (1GB).

    Incorrect answers:
    A: It’s better to put the data file and the log file of the new database on two different physical disks out of performance reasons.

    C: It’s better to put the data file and the log file of the new database on two different physical disks out of performance reasons.

    D: It’s better to put the data file and the log file of the new database on two different physical disks out of performance reasons.
