题目

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.

参考答案和解析
正确答案：A
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.

第1题：

You are the administrator of several SQL Server 2000 computers. A data Transformation Services (DTS) package uses native OLE DB providers to transfer data between the servers. Connection details for the servers are specified in .udl files. The .udl files are frequently updated as connection details change.

You want to distribute the DTS package as a file to developers in your company. You want to make sure connection details are available to developers who receive the DTS package.

Which two tasks should you perform? (Each correct answer presents part of the solution. Choose two)

A．Enable the Always read properties from UDL file option in the Connection Properties dialog box.

B．Disable the Always read properties from UDL file option in the Connection Properties dialog box.

C．Delete the .udl files and store connection details in the registry by using system data source names.

D．Delete the .udl files, and store connection details in the registry by using user data source names.

E．Make the .udl files available on a network share.


正确答案：AE
解析：Explanation:
A: To make the connection information available for the developers we must enable the Always read properties from UDL file option.

E: We provide the developers with access to the .udl file by placing the .udl files in a network share and setting appropriate share and NTFS permissions.

Note: In SQL Server 2000, DTS packages can use Microsoft Data Link (.udl) files to create OLE DB connections and resolve the connections in run time. With this feature we can encapsulate the connection properties from a DTS package into a separate file and can edit the connection string in a .udl file instead of the connection properties in a DTS package in situations where connection information such as the server name, login, or even the OLE DB provider may change.

When specifying a data link connection, we must first specify whether to load an existing .udl file or create a data link to save with DTS Designer. If we want to use a .udl file rather than saving the data link with DTS Designer, we can create one either from Windows Explorer or during the data link configuration process in DTS Designer. We must then click Microsoft Data Link in the Data Source list of the Connection Properties dialog box and check the Always read properties from UDL file check box. In this scenario, the .udl file is already specified.

Incorrect Answers:
B: If we clear the Always read properties from UDL file option in the Connection Properties dialog box, we would have to edit the connection properties through the Data Transformation Services (DTS) package. This would increase administrative effort.

C: We cannot delete the .udl files and instead store the connection details in the registry by using system data source names as the connection details change regularly.

D: We cannot delete the .udl files, and instead store connection details in the registry by using user data source names as the connection details change regularly.

第3题：

You are the database administrator for a retail company. The company owns 270 stores. Every month, each store submits approximately 2,000 sales records, which are loaded into a SQL Server 2000 database at the corporate headquarters.

A Data Transformation Services (DTS) package transforms the sales records, as they are loaded. The package writes the transformed sales records to the Sales table, which has a column for integer primary key values. The IDENTITY property automatically assigns a key value to each transformed sales record.

After loading this month's sales data, you discover that a portion of the data contains errors. You stop loading data, identify the problem records, and delete those records from the database.

You want to reuse the key values that were assigned to the records that you deleted. You want to assign the deleted key values to the next sales records you load. You also want to disrupt users' work as little as possible.

What should you do?

A．Export all records from the Sales table to a temporary table. Truncate the Sales table, and then reload the records from the temporary table.

B．Export all records from the Sales table to a text file. Drop the Sales table, and then reload the records from the text file.

C．Use the DBCC CHECKIDENT statement to reseed the Sales table's IDENTITY property.

D．Set the Sales table's IDENTITY_INSERT property to ON. Add new sales records that have the desired key values.


正确答案：C
解析：Explanation: DBCC CHECKIDENT is used to check the current identity value for the specified table. It can be set to correct the identity value by specifying the RESEED option with DBCC CHECKIDENT.

Note: Example:
Assume that we have a table called test with an identity column with seed (1,1) and 1000 rows and that we delete row 901 to 950. We could then issue the command
DBCC CHECKIDENT (test, reseed, 900)

And load the 50 missing rows. These rows would get the values 901, 902, …,950 in the identity column.
We should then set the identity value to 1000 again:
DBCC CHECKIDENT (test, reseed, 1000)

So that the next new row will have identity 1001.

Incorrect Answers:
A: Exporting the data from the Sales table and then reloading the data will not correct errors contained in the table as these errors will also be exported as they are part of the data already in the table.
B: Exporting the data from the Sales table and then reloading the data will not correct errors contained in the table as these errors will also be exported as they are part of the data already in the table.

D: The SET IDENTITY_INSERT command allows explicit values to be inserted into the identity column of a table. To reuse the old key values from the rows that was deleted would require manual commands and would be awkward. This is not the best solution.

第6题：

You are a database administrator in the Los Angeles branch office of a specialty foods supplier. A mainframe. database at the headquarters contains all company data. Each branch office contains a SQL Server 2000 computer that imports regional data from the mainframe. database.

The server in Los Angeles contains a Data Transformation Services (DTS) package that uses OLE DB to connect to the company's mainframe. database. The DTS package extracts and transforms data about buyers and products for that region. The DTS package then writes the data to the SQL Server database in Los Angeles.

You need to configure a SQL Server computer for the new branch office in Sydney. You want to copy the Los Angeles package and modify it so that it writes data to the SQL Server database in Sydney.

You use the DTS Designer to modify the DTS package so that it imports regional data from the mainframe. database to the server in Sydney. The modified DTS package runs successfully on the server in Los Angeles. You save this DTS package to the server in Sydney, but the server in Sydney cannot connect to the mainframe. database.

You want to enable the server in Sydney to connect to the mainframe. database. What should you do?

A．Change the connection properties in the DTS package so that the package uses new login credentials to connect to the mainframe. database.

B．Modify the workflow in the DTS package so that the server in Sydney is included.

C．On the server in Sydney, install an OLE DB provider for the mainframe. database.

D．On the server in Sydney, delete and then re-create the DTS package.


正确答案：C
解析：Explanation: OLE DB is an API that allows COM applications to use data from OLE DB data sources, which includes data stored in different formats. An application uses an OLE DB provider to access an OLE DB data source. An OLE DB provider is a COM component that accepts calls to the OLE DB API and performs the necessary processing required by request against the data source. In this scenario the OLE DB source is the company's mainframe. database, which contains all company data. As each branch office contains a SQL Server 2000 computer that imports regional data from the mainframe. database, all existing and future branch office SQL Server 2000 servers will require an OLE DB provider to access the company's mainframe. database.

Incorrect Answers:
A: The DTS package requires an OLE DB provider to access an OLE DB data source. It needs this provider to connect to the company's mainframe. database. Resetting the connection properties in the DTS package so that the package uses new login credentials to connect to the mainframe. database will not provide the DTS package with the required access to the mainframe. database.

B: A separate DTS package must be created for the Sydney branch office. This DTS package must extract data from the company's mainframe. computer that is relevant to the branch office in Sydney. The existing DTS package used to extract data from the company's mainframe. for the Los Angeles SQL Server 2000 server can be modified to serve the same function for the Sydney office.

D: Re-creating the DTS package on the SQL Server 2000 server in the branch office in Sydney is unnecessary the that SQL Server 2000 server would still require an OLE DB provider to access the company’s mainframe. database. It would require less administrative effort to modify the existing DTS package.

第7题：

You are the administrator of a SQL Server 2000 computer. The server contains confidential information about contracts on which your company has placed bids.

Company policy requires that bid information be removed permanently from the database one year after the bid closes. You need to comply with this policy and minimize server overhead.

What should you do?

A．Create a Data Transformation Services (DTS) package to remove bids that have a closing data older than one year.

B．Create a trigger to delete any bids that have a closing data older than one year. Bind the trigger to the bids table for all INSERT, UPDATE, and DELETE events.

C．Create a stored procedure to delete any bids that have a closing data order than one year. Use SQL server agent to schedule the stored procedure to run every night.

D．Create a view that contains a WHERE clause to exclude bids that have a closing date older than one year.

第8题：

You are the administrator of a SQL Server 2000 computer. The server contains a Data Transformation Services (DTS) package that queries multiple databases and writes the results to a text file. You run this package by using a Microsoft Windows batch file. The batch file uses the dtsrun utility to execute the DTS package.

You want to ensure that connection properties, such as login names and passwords, cannot be read or modified by users. Which two actions should you take? (Each correct answer represents part of the solution. Choose two.)

A．Save the DTS package so that it has an owner password.

B．Save the DTS package so that it has a user password.

C．Encrypt the DTS package details in the command line of the dtsrun utility.

D．Store the DTS package in the Meta. Data Services repository.

E．Store the DTS package as a Microsoft Visual Basic file.


正确答案：AC
解析：Explanation: In this scenario we will use a windows batch file with the owner password for maximum security.

A: When running the Dtsrun utility on a package you must either specify a user password or a package password. Specify a password for the package to protect sensitive user name and server password information in the package from unauthorized users with owner password. If the package has an owner password, the data is encrypted with the standard encryption API. This protects protect sensitive user name and server password information in the package from unauthorized user.
.
C: You can encrypt the command prompt options to be executed by the DTS Run utility, allowing you to create an encrypted dtsrun command for later use. This will ensure that login names, password and other command line options cannot be read or modified by users.

Note: When a package is saved to SQL Server or as a structured storage file, DTS package passwords can be assigned to the package. These passwords are used in addition to the Windows Authentication or SQL Server Authentication passwords to connect to an instance of SQL Server.

There are two types of DTS package passwords that can be set: an owner password and a user password. If an owner password is set, the package user needs the password to edit or run the package and if a user password is set, the package users with access to the user password can run the package.

Incorrect Answers:
B: There is no need to create a user password. The package will be run with an owner password. The owner password will be protected since the command options are encrypted.

D: The Meta. Data Services repository is the storage container for the meta. data used by Analysis Services. Meta. data is stored in tables in a relational database and is used to define the parameters and properties of Analysis server objects. DTS package information can be saved to Meta. Data Services. This saves meta. data information about the databases referenced in the package, which can be viewed though the DTS Browser.

E: When a DTS package is saved as a Visual Basic file, these files can be used as templates, or starting points, for user-implemented Visual Basic packages. The generated code sets all properties of all objects referenced in the package to the initial values they will have when package execution begins. This includes those that are set to their default values.

You are the administrator of two SQL Server 2000 computers. One of these servers contains a 4-GB database named marketing. You want to remove the marketing database from one server and add it to the other as quickly as possible.

What should you do?

A．Detach the database from the original server by using the sp_detach_db stored procedure. Copy the database and the transaction log files to the new server, and attach them by using the sp_attach_db stored procedure.

B．Use the DTS export wizard to transfer all database objects from the original server to the new server. Drop the database from the original server.

C．Run a full backup of the database on the original server. Create a new database named marketing on the new server. Restore the backup in the new marketing database. Drop the database from the original server.

D．Shut down the original server. Copy the database and the transaction log files to the new server. Use the DISK INIT and DISK REFIT statements to attach the data file to the new server. Drop the database from the original server.
