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4题：

You are the administrator of a SQL Server 2000 computer. The server contains a database that stores financial data. You want to use Data Transformation Services packages to import numeric data from other SQL server computers. The precision and scale values of this data are not defined consistently on the other servers.

You want to prevent any loss of data during the import operations. What should you do?

A．Use the ALTER COLUMN clause of the ALTER TABLE statement to change data types in the source tables. Change the data types so that they will use the lowest precision and scale values of the data that will be transferred.

B．Use the ALTER COLUMN clause of the ALTER TABLE statement to change data types in the destination tables. Change the data types to reflect the highest precision and scale values involved in data transfer.

C．Set a flag on each DTS transformation to require an exact match between source and destination columns.

D．Set the maximum error count for each DTS transformation task equal to the number of rows of data you are importing. Use an exception file to store any rows of data that generate errors.

E．Write Microsoft ActiveX script. for each DTS transformation. Use the script. to recast data types to the destinations precision and scale values.


正确答案：B
解析：Explanation: The ALTER COLUMN clause of the ALTER TABLE statement can be used to change the definition of a column and can be used to alter the precision and scale values of the data types. The destination precision should be changed so no data would be lost. The transformation to a data type with higher precision is automatic and would not require any coding.

Note: The precision of the data type refers to the number of digits in a number while the scale is the number of digits to the right of the decimal point in a number. Thus the number 702.85 has a precision of 5 and a scale of 2. The default maximum precision of numeric and decimal data types is 38.

Incorrect Answers:
A: The ALTER COLUMN clause of the ALTER TABLE statement can be used to change the definition of a column and can be used to alter the precision and scale values of the data types. However, we want to prevent any loss of data therefore we need to ensure that the data being imported correlates with the definition of the destination column. If it does not, any constraint that might exist on the destination column will prevent the data from being inserted.

C: Setting DTS transformation to require an exact match between source and destination columns refers to the data in the columns.

D: When the a maximum error count value for a DTS transformation task specifies the sum of row-level errors detected by the Transform. Data task and batch failures. When the Max error count value is exceeded, DTS task execution is terminated. Because rows containing errors detected by the DTS transformation task are discarded before batch submission, these errors do not trigger nor count as batch failures. Errors caught at the destination will fail the batch and add one to the error count regardless of how many rows are in the batch.

E: Recasting data types to the destinations precision could result in loss of data. The destination precision should be changed so no data would be lost.

Note: The capabilities of a Data Transformation Service package can be extended by using
Microsoft ActiveX scripts that implement the objects, properties, methods, and collections of the DTS object model. With ActiveX scripts the data can be formatted and transformed as it is copied from its source to the destination location.

An ActiveX script. transformation applies to tasks that work on the source data on a row-by-row basis and can be used to replace a two-digit state code in the source data with the legal abbreviation of the state in the destination data; set columns to a default of spaces, validate important columns in the source data and skip records that contain invalid data to prevent them from being copied to the destination, and alter the precision and scale values of data as the data copied from the source to the destination.

第5题：

You are the administrator of a SQL Server 2000 computer. Your company uses the server to store service contract information for its customers.

You are also the administrator of Oracle relational database management system (RDBMS) server.

This server is used to store your company’s financial information. The financial information is updated frequently throughout the day.

You need to create a series of reports that combine the service contract information and the financial information. These reports will be updated several times a day.

You want to create reports on the SQL Server computer by using the minimum amount of disk space.

What should you do?

A．Set up SQL server replication to replicate the data from the oracle server to the SQL server computer.

B．Set up the oracle server as a linked server. Create a view that joins the service contract information and the financial information.

C．Set up data transformation services (DTS) package that imports and transforms the database from the oracle server to the SQL server computer. Use SQL server agent to execute the DTS package throughout the day as needed.

D．Set up Microsoft ActiveX script. that connects to the oracle server and imports the financial information into SQL server temporary table. Create a view that joins the service contract information and the temporary table.


正确答案：B
解析：Explanation: SQL Server 2000 permits the creation of links to OLE DB data sources called linked servers. After linking to an OLE DB data source, it is possible to reference rowsets from the OLE DB data sources as tables in Transact-SQL statements and to pass commands to the OLE DB data sources and include the resulting rowsets as tables in Transact-SQL statements.

Each distributed query can reference multiple linked servers and can perform. either update or read operations against each individual linked server. A single distributed query can perform. read operations against some linked servers and update operations against other linked servers. The Microsoft OLE DB Provider for Oracle allows distributed queries to query data in Oracle databases.

Incorrect Answers:
A: Replication allows for the coping, distribution, and modification of data across an enterprise. This involves the copying of database data from one server to another. This is not the best solution in this scenario as this will require frequent replication because the reports must be updated several times a day.

C: Data Transformation Services is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.

D: Microsoft ActiveX scripts can be used to add functionality to Data Transformation Services packages, which is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.

第6题：

You are the administrator of SQL Server 2000 computer named FABSQL2K01. You create a Data Transformation Services package that contains definition for two transform. data tasks.

The tasks gets data from two text files named Customers and Sales. The DTS package is configured as shown in the exhibit.

You do not want the DTS package to add any data to the server unless both transform. data tasks complete successfully.

You select the use transactions check box of DTS package and the Join transaction of present check box of both transform. data tasks. You then select the fail package on step failure check box of both transform. data tasks.

You want to use the DTS package to import data from the text files to the server. You want to ensure that changes are committed if all imported data is successfully transformed.

What should you do?

A．Select the commit on successful completion check box of the DTS package.

B．Select the commit transaction on successful completion of this step check box of the customers transform. data task.

C．Select the commit transaction on successful completion of this step check box of the sales transform. data task.

第7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.


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8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9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.

第10题：

You are the administrator of a SQL Server 2000 computer. Your company purchased an accounting application from a vendor. The application stores its data in a database named Accounting on the server. The tables in this database contain columns that function as primary keys, but PRIMARY KEY and FOREIGN KEY constraints are not used.

You need to replicate data from this database to another SQL Server computer. This server will use the replicated data to generate reports. Most reports will run each month, but the accounting department needs to have the ability to run reports at any time. Reports should be accurate through the last full working day.

You cannot make any changes to the database, but you need to implement replication. Which two actions should you take? (Each correct answer presents part of the solution. Choose two)

A．Implement merge replication.

B．Implement snapshot replication.

C．Implement transactional replication.

D．Schedule replication to run continuously.

E．Schedule replication to run during off-peak hours.


正确答案：BE
解析：Explanation:
B: Snapshot replication is the best solution since we will not be making changes to the Accounting database but need to replicate data from the database to another SQL Server computer and as the accounting department needs to have the ability to run reports that only need to be accurate through the last full working day.

E: Only one snap-shot replication would be necessary per day, and to make as little impact on the daily use of the server this replication should be scheduled during off-peak hours.

Note: SQL Server 2000 provides three types of replication that can be used in distributed applications. These are snapshot replication, transactional replication and merge replication. Each type provides different capabilities.

Snapshot replication is the process of copying and distributing data and database objects exactly as they were at the time the snapshot was taken. Snapshot replication does not require continuous monitoring of changes because changes made to published data are not propagated to the Subscriber incrementally. Subscribers are updated with a complete data set and not individual transactions. As snapshot replication replicates an entire data set at one time, it may take longer to propagate data modifications to Subscribers. This type of replication in helpful in situations when data is mostly static and does not change often; it is acceptable to have copies of data that are out of date for a period of time; replicating small volumes of data; and when sites are often disconnected and high latency (the amount of time between when data is updated at one site and when it is updated at another) is acceptable.

In transactional replication, an initial snapshot of data is propagated to Subscribers, and then when data modifications are made at the Publisher, the individual transactions are captured and propagated to Subscribers. SQL Server 2000 monitors INSERT, UPDATE, and DELETE statements, and changes to stored procedure executions and indexed views. SQL Server 2000 stores the transactions affecting replicated objects and then it propagates those changes to Subscribers continuously or at scheduled intervals. Transaction boundaries are preserved. Transactional replication is used when data modifications must be propagated to Subscribers, often as they occur; transactions must be atomic; subscribers are mostly connected to the Publisher and when the application will not tolerate high latency for Subscribers receiving changes.

Merge replication allows various sites to work autonomously and merge data modifications made at multiple sites into a single, uniform. result at a later time. The initial snapshot is applied to Subscribers and then SQL Server 2000 tracks changes to published data at the Publisher and at the Subscribers. The data is synchronized between servers either at a scheduled time or on demand. Updates are made independently at more than one server, so the same data may have been updated by the Publisher or by more than one Subscriber. Therefore, conflicts can occur when data modifications are merged. This type of replication is helpful when multiple Subscribers need to update data at various times and propagate those changes to the Publisher and to other Subscribers; Subscribers need to receive data, make changes offline, and synchronize changes later with the Publisher and other Subscribers; the application latency requirement is either high or low, and when site autonomy is critical.

Incorrect Answers:
A: No data at the second server will not be changed so there is no need to use merge replication.

C: We don’t need the accuracy of transactional replication. In this scenario high latency is permissible as the reports must be accurate only through the last full working day.

Note: Transactional replication is used when data modifications must be propagated to Subscribers, often as they occur; transactions must be atomic; subscribers are mostly connected to the Publisher and when the application will not tolerate high latency for Subscribers receiving changes.

D: As the reports must be accurate through the last full working day, it not necessary to run replication continuously. Running replication continuously will place locks on the destination database, which would hamper the performance of queries and actions run against the destination database.
