Exhibit:
BULK INSERT Ezonexam.dbo.employees
FROM ‘tk\africe\fubar512.txt’
WITH DATAFILETYPE = ‘char’,
FIELD/TERMINATOR = ‘\t’,
ROWTERMINATOR = ‘\n,’
TABLOCK
You work as database administrator at Ezonexam.com. You handle one SQL Server 2000 computer.
How should you improve the performance of the query in the exhibit above?
A. Extend the BULK INSERT statement with the BATCHSIZE option set it to equal to 5 percent of the number of rows to be loaded.
B. Extend the BULK INSERT statement with the BATCHSIZE option set it to equal to 10 percent of the number of rows to be loaded.
C. Extend the BULK INSERT statement with the ROWS_PER_BATCH option set it to equal to 5 percent of the number of rows to be loaded.
D. Extend the BULK INSERT statement with the ROWS_PER_BATCH option set it to equal to 10 percent of the number of rows to be loaded.
E. Insert a line before the BULK INSERT statement that drops the indexes for the customers table. Insert a line after the BULK INSERT statement that recreates the indexes for the customers table.
F. The TABLOCK option should be removed.
G. The ROWTERMINATOR line should be removed.
F 解析：Explanation: The TABLOCK hint increases the number of locks during the adding process. This is the reason why response time are slows down during this process. By removing the TABLOCK hint the default more granular row-level lock will be used. This would decrease the scope of the locks which would result in less waiting jobs and performance would improve.
Note: The BULK INSERT statement is used to copy a data file into a database table or view in a format specified by the user. The BULK INSERT statement accepts the TABLOCK hint, which allows the user to specify the locking behavior. that the BULK INSERT statement should use. TABLOCK specifies that a bulk update table-level lock is taken for the duration of the bulk copy. If TABLOCK is not specified, the default uses row-level locks.
Incorrect Answers:
A, B, C, D: Effect would not be large
E: Some improvement, but not the best answer.
G: Would make the batch to stop working.
第4题：
You are the administrator of a SQL Server 2000 computer. The server is configured as shown in the Database Server Configuration exhibit.
You need to create a new database named Inventory. Employees in your company will use the Inventory database to track inventory data. Users will require immediate responses to queries that help them locate where parts are stored. The tables in the database will be configured as shown in the Database Schema exhibit.
The database will consume 14 GB of disk space. You must configure the data files and transaction log to accelerate query response time.
Which two courses of action should you take? (Each correct answer represents part of the solution. Choose two.)
A. On drive C, create a transaction log.
On drive D, create a data file in the PRIMARY filegroup.
On drive E, create a data file in the SECONDARY filegroup.
B. On each drive, create a transaction log.
On each drive, create a data file in the PRIMARY filegroup.
C. On drive D, create a transaction log.
On drive E, create a data file in the PRIMARY filegroup.
D. On the PRIMARY filegroup, create all tables and all indexes.
E. On the PRIMARY filegroup, create all tables. On the SECONDARY filegroup, create all indexes.
F. On the PRIMARY filegroup, create the Parts table and its indexes.
On the SECONDARY filegroup, create all other tables and their indexes.
A,E 解析：Explanation:
A: The transaction log should be placed on a separate disk. A transaction log would not benefit of two or more disks since it is sequential. Create two data files on two separate physical disks would improve performance.
E: Separating the tables and the indexes improve performance for in particular joins.
Note: With SQL Server 2000 it is possible to create tables or indexes on specific filegroups. This allows us to control where the database's tables and indexes are physically located as filegroups can be placed on different hard drives. Placing tables in one filegroup and the table's nonclustered indexes in another filegroup on different physical disk can improve database performance because it will allow separate threads to access the tables and indexes.
However, a table and its clustered index cannot be separated into different filegroups as the clustered index determines the physical order of the data in the table. Furthermore, the transaction log should be placed on a physically separate disk. The transaction log file is written serially; therefore, using a separate, dedicated disk allows the disk heads to stay in place for the next write operation. This will further improve performance.
Incorrect Answers:
B: To improve performance, the transaction log should not be placed on the same physical disk that the tables or indexes are placed on. The transaction log file is written serially; therefore, placing it on a separate, dedicated disk allows the disk heads to stay in place for the next write operation and thus improves performance.
Furthermore, placing tables in one filegroup and the table's nonclustered indexes in another filegroup on different physical disk can improve database performance because it will allow separate threads to access the tables and indexes. However, a table and its clustered index cannot be separated into different filegroups as the clustered index determines the physical order of the data in the table.
C: The transaction log should be placed on a physically separate disk. The transaction log file is written serially; therefore, using a separate, dedicated disk allows the disk heads to stay in place for the next write operation. This will further improve performance. In this solution, the tables and their indexes are placed on the same disk. This solution thus does not take advantage of the performance improvements that can be realised through the correct utlization of the available hardware.
D: In this solution, the tables and their indexes are placed on the same disk. This solution thus does not take advantage of the performance improvements that can be realised through the correct utlization of the available hardware.
F: Greater performance gains can be realized by placing tables in one filegroup and the table’s nonclustered indexes in another filegroup on different physical disk. This will allow separate threads to access the tables and indexes.
第5题：
You are the administrator of a SQL Server 2000 computer. You create a Data Transformation Services (DTS) package. The package is stored as a local package on the server. The package exports data from an online transaction processing (OLTP) database system to an online analytical processing (OLAP) database system that is located on a second SQL Server 2000 computer.
You want the package to execute automatically each evening at 8:00 P.M. What should you do?
A．Use SQL Server Enterprise Manager to create a new job Create a CmdExec job step that runs the dtsrun utility Schedule the job to run each night at 8:00 P.M.
B．Use SQL Server Enterprise Manager to create a new job Create a Transact-SQL job step to query data from the OLTP database Create a second Transact-SQL job step to launch the DTS package Schedule the job to run each night at 8:00 P.M.
C．Create a batch file that runs the dtsrun utility Use the Microsoft Windows Task Scheduler to run the job each night at 8:00 P.M. Configure the Windows Task Scheduler to use the local system account
D．Move the DTS package to the repository Configure the SQLServerAgent service on the OLAP database server to update the package each night at 8:00 P.M.
解析：Explanation: Transfers can be defined and stored in a DTS package, which can then be run from a command line using the dtsrun utility (DTSRUN.EXE). CmdExec job steps are operating system commands or executable programs ending with .bat, .cmd, .com, or .exe. In this scenario we create a job consisting of a single cmdexec job step which runs the DTS package using the dtsrun utility.
Incorrect answers:
B: Only one job, not two, has to be created at the OLTP database server.
C: If the Task Scheduler is running as the local system account it wouldn’t be able to access the remote OLAP database server.
D: The DTS export package should be run at the OLTP database server, not at the OLAP database server. The DTS package is exported from the OLTP server to the OLAP server.

You are the administrator of a SQL server computer. The server is running SQL Server 6.5 and SQL Server 7.0.
You install a named instance of SQL Server 2000, and then run the SQL server upgrade wizard. On the database selection screen, some of the SQL Server 6.5 databases are not listed.
You cancel the SQL Server upgrade wizard.
You need to ensure that the SQL Server 6.5 databases are listed in the wizard. What should you do?
A．Uninstall SQL Server 7.0, and then rerun the SQL Server upgrade wizard.
B．Run the Microsoft SQL Server-switch application, and then rerun the SQL Server upgrade wizard.
C．Create a data transformation services package that imports the databases from SQL Server 6.5 to SQL Server 2000, and then execute the package.

第7题：
You are the administrator of a SQL server 2000 computer that contains a database named Acct. The database contains 1.5 GB of data. The server has one 9-GB hard disk that is configured as shown in the Exhibit.
You need to import data into the database without adversely affecting database performance. The data will require an additional 2GB of storage space.
What should you do?
A．Add another data file on drive E, and then add the file to the PRIMARY filegroup.
B．Move the transaction log file to drive E, and set the file growth of Acc_Data.mdf by selecting the Unrestricted file growth option.
C．Rebuild all clustered indexes so that they have a fill factor of 100.
D．Compress drive D.
解析：Explanation: We must take precautions so that the import process of 2 GB data will run. We add a new file to drive E, which has 3 GB free disk space. By placing the new file in the primary file group we ensure that new data added to the database will be added to new data file. The primary file group is the default file group and new data is automatically added to it.
Incorrect Answers:
B: Moving the transaction log from Drive D to Drive would free up 800MB. This would leave 1.3GB of free disk space on drive D. But the import process will require another 2GB so we will not have enough free disk space.
C: Rebuilding the clustered indexes with a fill factor of 100 makes that the index pages full. This would degrade performance during the import process due to page splits.
D: Compressing a partition which is used by SQL Server is not a good idea. It would, if at all possible, degrade performance.

第9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.
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.
