NO.4 You are developing a SQL Server 2008 Integration Services (SSIS) data flow that extracts data from
two sources.
Each source database is located on a different server. Each source is based on a SELECT statement that
uses an ORDER BY clause.
The data flow is as shown in the following diagram.
When the paths from the two sources are connected to a Merge Join component, the following error
message is displayed:
"Data Flow Task: The input is not sorted. The 'input "Merge Join Left Input" (80)' must be sorted."
You need to ensure that data from each query is included in each row in the data flow. You want to
achieve this goal by using minimum amount of execution time.
What should you do?
A. Add a Sort transformation for each data flow.
B. Add an OLE DB Command transformation for each data flow.
C. Update the sorting properties in each source component.
D. Replace the Merge Join transformation with a Union All transformation.
Answer: C

NO.5 You design a SQL Server 2008 Integration Services (SSIS) package that contains several data flows.
You need to monitor the data that passes through each path in the data flow by using the Business
Intelligence Development Studio. You also need to ensure that data flow logic is retained.
What should you do?
A. Use the Data Viewer tool.
B. Use the Data Profiling task.
C. Use the Audit transformation.
D. Use breakpoints in the Script component.
Answer: A

NO.6 You implement a SQL Server 2008 Integration Services (SSIS) package.
The package contains the following components:
¡¤A Foreach Loop container for the Collection property as shown in the following exhibit. (Click the Exhibit
button.)
¡¤A Foreach Loop container for the Variable Mapping
property as shown in the following exhibit. (Click the
Exhibit button.)
¡¤A String variable named FileName
¡¤A String variable named DirectoryPath
You need to update the package so that the DirectoryPath variable returns the directory path for the file
path stored in the FileName variable.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Set the RaiseChangedEvent property of the User::FileName variable to True.
B. Set the EvaluateAsExpression property of the User::DirectoryPath variable to True.
C. Add a Script task to the OnPostExecute event handler of the Foreach Loop container.
D. Set the Expression property of the User::DirectoryPath variable to the following expression.
SUBSTRING( @[User::FileName], 1, LEN( @[User::FileName] ) -
FINDSTRING( REVERSE( @[User::FileName] ), "\\", 1 ))
E. Set the Expression property of the User::FileName variable to the following expression.
SUBSTRING( @[User::FileName], 1, LEN( @[User::FileName] ) -
FINDSTRING( REVERSE( @[User::FileName] ), "\\", 1 ))

NO.9 You design a SQL Server 2008 Integration Services (SSIS) package. The package extracts data from
flat files and loads this data to a SQL Server 2008 database.
The package contains two Boolean variables named @IsWeekday and @IsHoliday. When the package is
executed on week days, the @IsWeekday variable is set to True. When the package is executed on
holidays, the @IsHoliday variable is set to True. You need to implement the following business logic in the
control flow of the package:
¡¤When the @IsWeekday variable is set to True, the Perform Weekday Processing Data Flow task is
executed.
¡¤When the @IsWeekday variable is set to False, the Perform Weekend Processing Data Flow task is
executed.
¡¤When the @IsHoliday variable is set to True, the Perform Holiday Processing Data Flow task is
executed.
Which control flow logic should you implement?
A.
B.
C.
D.
