Title : TS:MS SQL Server 2008.Business Intelligence Dev & Maintenan


1. 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.
Answer: A

2. 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

3. 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 Mappings 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 ))
Answer: BD

4. You modify a SQL Server 2008 Integration Services (SSIS) packagE.The package extracts data from a text file and loads this data to a SQL Server 2008 table as shown in the following two exhibits.
You need to update the package to extract data from multiple text files of the same directory.
Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)
A.Add a variable to the package.
B.Add a variable to the data flow task.
C.Add a Foreach Loop container to the package.
D.Add a For Loop container to the package.
E.Add an expression to the Flat File Source component.
E.Add an expression to the Flat File connection manager.
Answer: ACF

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

6. You design a SQL Server 2008 Integration Services (SSIS) data flow that inserts data from a source query to a destination table.
You need to insert only those rows that do not already exist in the destination tablE.What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A.Use the Merge transformation.
B.Use the Lookup transformation.
C.Use the Union All transformation.
D.Use the Merge Join transformation.
E.Use the Fuzzy Lookup transformation.
E.Use the Fuzzy Grouping transformation.
Answer: BD

7. You are developing a SQL Server 2008 Integration Services (SSIS) data flow that loads data to a SQL Server 2008 database.
You need to ensure that the data flow updates the existing records in the SQL Server database by using data from the rows in your data flow.
Which data flow component should you use?
A.SQL Server Destination
B.OLE DB Destination
C.OLE DB Command Transformation
D.Data Conversion Transformation
Answer: C

8. You are designing a SQL Server 2008 Integration Services (SSIS) packagE.The package includes a Data Flow task that copies several million rows. The data flow requires a match against a reference table that contains 10,000 rows. Each row in the reference table will be used during the data flow.
You need to ensure that the data flow executes in the minimum amount of time.
Which data flow component should you select?
A.a Fuzzy Lookup transformation
B.a Lookup transformation along with the Full cache option
C.a Lookup transformation along with the No cache option
D.a Lookup transformation along with the Partial cache option
Answer: B
