You are the database administrator of a SQL Server 2000 computer. The server contains your company's Accounts database. Hundreds of users access the database each day.Because you have had power interruptions in the past, you want to protect the physical integrity of the Accounts database. You do not want to slow down server operations.What should you do?

A) Create a database maintenance plan to check database integrity and make repairs each night. B) Enable the torn page detection database option for each database.
C) Disablewrite caching on all disk controllers. D) Ensure that write caching disk controllers have battery backups.

Q:

You are an administrator of a SQL Server 2000 computer. The server contains a database that stores inventory data. Another database administrator has created a number of scheduled jobs to maintain the inventory database. Each weeknight the following jobs occur.


- A BULK INSERT job imports data at 10:00 P.M
- Indexes are rebuilt at 10:15 P.M
- Data integrity checks are performed at 10:30 P.M
- A differential backup is performed at 10:45 P.M
- A DBCC SHRINKDATABASE job runs at 11:00 P.M.


You notice that the final job often fails and returns the following error message: "Server: Msg 3140, Level 16, State 3. Could not adjust the space allocation for file  'inventory_data'."You need to ensure that the final job runs without errors.

What should you do?

A) Modify the DBCC SHRINKDATABASE job so that it uses DBCC SHRINKFILE statement to shrink each file individually. B) Create a new DBCC SHRINKFILE job to shrink the inventory_data file. Schedule the new job to run at the same time as the DBCC SHRINKDATABASE job.
C) Increase the time between the differential backup and the DBCC SHRINKDATABASE job. D) Increase the time between the data integrity checks and the differential backup.
 
Answer & Explanation Answer: C) Increase the time between the differential backup and the DBCC SHRINKDATABASE job.

Explanation:

The DBCC SHRINKDATABSE cannot be executed until the previous job step, the differential backup, has been completed. We should increase the time between these two job steps, or even better configure the last job step to run only after the differential backup has been completed.

 

Note: The DBCC SHRINKDATABASE statement shrinks data files on a per-file basis but shrinks log files as if all the log files existed in one contiguous log pool. The target size for the data and log files cannot be smaller than the minimum size of a file that was specified when the file was originally created, or the last explicit size set with a file size changing operation such as the ALTER DATABASE statement with the MODIFY FILE option or the DBCC SHRINKFILE statement.

Q:

You are the administrator of a SQL Server 2000 computer. You configure SQL Server to perform C2 auditing. Audit logs are saved in the C:MSSQLAudit folder.The server functions normally for several days, but then the MSSQLServer service shuts down without warning. You cannot restart the service.You need to restart the MSSQLServer service. What should you do?

A) Start the MSSQLServer service manually by using the -m startup option. B) Start the MSSQLServer service manually by using the -s startup option.
C) Set the SQLServerAgent service's startup method to Disabled. Start the MSSQLServer service. D) Delete the audit logs from the C:\MSSQL\Audit folder. Start the MSSQLServer service.
 
Answer & Explanation Answer: D) Delete the audit logs from the C:\MSSQL\Audit folder. Start the MSSQLServer service.

Explanation:

SQL Server functioned for several days but now it is impossible to start it.
The most likely cause is the size of the auditing log files. The maximum file size for the audit log is fixed at 200 megabytes (MB). When the audit log file reaches 200 MB, a new file will be created and the old file handle will be closed. If the directory fills up, then the instance of Microsoft SQL Server is stopped. The system administrator needs to either free up disk space for the audit log before restarting the instance of SQL Server or restart the instance of SQL Server

Note 1: SQL Server Agent monitors itself and the SQL Server service.
SQL Server Agent can restart the local instance of SQL Server if it has terminated for reasons other than a typical shutdown.

Note 2: Start the MSSQLServer service manually by using the -f startup option would start the service with minimal configuration. It could be used when some configuration errors have been made and the MSSQLServer service isn't able to start.

Q:

You are the administrator of a SQL Server 2000 computer. The server contains a database named FinanceData that is used by a client/server application. Each employee has a SQL Server login that the application uses to access the server.Your company hires a new employee named Andrew. You create a SQL Server login named Andrew. You also create a database user named Andrew in the database and grant the database user full permissions in the database.Whenever Andrew runs the client/server application, he receives the following error message: "Invalid object name." Andrew also reports that he cannot access the database by using the application.You need to ensure that Andrew can use the application. Which Transact-SQL statement should you execute?

A) EXEC sp_defaultdb 'Andrew','FinanceData' B) GRANT ALL ON FinanceData TO Andrew
C) EXEC sp_addlogin 'Andrew' D) EXEC sp_grantdbaccess 'FinanceData','Andrew'GOsp_addrolemember 'db_datareader','Andrew'
 
Answer & Explanation Answer: A) EXEC sp_defaultdb 'Andrew','FinanceData'

Explanation:

Error 208 produces the message 'Invalid object name' and occurs when an object that does not exist in the current database is referenced. If the object exists in another database, we must use the USE statement to explicitly switch the context to the correct database or we must qualify the object name with the database name. A third option is to use the sp_defaultdb stored procedure. This stored procedure is used to change the default database for a login. When a client connects with SQL Server, the default database defined for its login becomes the current database without an explicit USE statement. The default database can be defined when the login is added with
sp_addlogin. When executing sp_addlogin the master database is the default database if a database is not specified. In this scenario a SQL Server 2000 login and a user account has been created for Andrew and he has been given database access and the required permissions.

Q:

You are the database administrator for a financial services company. Employees enter data 24 hours a day into a SQL Server 2000 database. These employees report slower response times when new account information is gathered from branch offices and added to the database. You currently use the following BULK INSERT statement to add the account information.BULK INSERT finance.dbo.customersFROM 'd:bulkaccts143_10142000.txt'WITH DATAFILETYPE = 'char', FIELDTERMINATOR = 't', ROWTERMINATOR = 'n', TABLOCK You want to ensure that response times do not slow when new account information is added to the database. What should you do?

A) Add the BATCHSIZE option to the BULK INSERT statement, and then set the option equal to 10 percent of the number of rows to be loaded. B) Add the ROWS_PER_BATCH option to the BULK INSERT statement, and then set the option equal to 10 percent of the number of rows to be loaded.
C) Drop the indexes for the Customers table before the data load, and then re-create the indexes after the data load is complete. D) Remove the TABLOCK option from the BULK INSERT statement.
 
Answer & Explanation Answer: D) Remove the TABLOCK option from the BULK INSERT statement.

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.

Q:

You create an ASP.NET application to provide corporate news and information to XYZ’s employees. The application is used by employees in New Zealand.


Default.aspx has a Web Form label control named currentDateLabel. The Page.Load event handler for Default.aspx included the following line of code:
currentDateLabel.Text = DateTime.Now.ToString(“D”)


You need to ensure that the data is displayed correctly for employees in New Zealand. What should you do?

A) In the Web.config file for the application, set the culture attribute of the globalization element to en-NZ. B) In the Web.config file for the application, set the uiCulture attribute of the globalization element to en-NZ.
C) In Visual Studio .NET, set the responseEncoding attribute in the page directive for Default.aspx to UTF-8. D) In Visual Studio .NET, save the Default.aspx page for both versions of the application by selecting Advanced Save Options from the File menu and selecting UTF-8.
 
Answer & Explanation Answer: A) In the Web.config file for the application, set the culture attribute of the globalization element to en-NZ.

Explanation:

The culture attribute of the globalization element specifies the default culture for processing incoming Web requests.

 

Incorrect Answers:

 

B: The uiculture attribute of the globalization specifies the default culture for processing locale dependent resource searches. It does not apply in this scenario.

 

C, D: The UTF8Encoding Class class encodes Unicode characters using UCS Transformation Format, 8-bit form (UTF-8). This encoding supports all Unicode character values and surrogates. However, it does not help in displaying data in New Zealand format.
