QUESTION 235
Drag and Drop Question
You are an ETL Developer for a mortgage company.

The following table shows Stg_Loan sample data:
 
The following table shows Loan sample data:
 
You need to build the ETL package.
What should you do? (To answer, drag the appropriate components to the correct locations in the answer area. Each component may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)
 
Answer:
 

QUESTION 236
You are an ETL developer for a mortgage company. In your application you have to load data from a Microsoft Excel source and an OLE DB source.
The Excel source contains vendor data and has approximately 1000 records.
The OLE DB source contains loan data and has approximately 1,000,000 records.
Sample vendor data (Excel source) is shown in the following table:
 
Sample loan data (OLE DB source) is shown in the following table:
 
The CIO asks you to generate an Excel file with the loan list information for each vendor.
You build a SQL Server 2008 Integration Services (SSIS) package that can generate the Excel files dynamically. The Excel files should have the vendor name as the prefix and the date as the suffix (e.g., VendorA_DDMMYYYY.xlsx).
You get the error message shown in the exhibit. (Click the Exhibit button.)
 
You need to sort both sources in order to merge join the data.
What should you do?

A.    Sort the data in the select statement of the OLE DB source and use Sort transformation after the
Excel source.
B.    Set the IsSorted property to True for OLE DB, sort the data in the select statement of the OLE DB
source, and use Sort transformation after the Excel source.
C.    Set the IsSorted property to True for both the OLE DB and Excel sources.
D.    Use Sort transformation after the OLE DB source and set the IsSorted property to True for the Excel
destination.

Answer: B

QUESTION 237
You develop a SQL Server 2008 Integration Services (SSIS) package.
You need to modify the package to log event data from a text file to the SQL Server database.
Which two actions should you perform?
(Each correct answer presents part of the solution.
Choose two.)

A.    Modify the Flat File Destination.
B.    Modify the log provider.
C.    Move the package file to the new path.
D.    Modify the Connection Manager.

Answer: BD
Explanation:
B: The SQL Server log provider, which writes log entries to the sysssislog table in a SQL Server database.
D: A package typically includes at least one connection manager. A connection manager is a link between a package and a data source that defines the connection string for accessing the data that the tasks, transformations, and event handlers in the package use. Integration Services includes connection types for data sources such as text and XML files, relational databases, and Analysis Services databases and projects.
Note: A log is a collection of information about the package that is collected when the package runs. For example, a log can provide the start and finish time for a package run. A log provider defines the destination type and the format that the package and its containers and tasks can use to log run-time information.
The logs are associated with a package, but the tasks and containers in the package can log information to any package log. Integration Services includes a variety of built-in log providers for logging. For example, Integration Services includes log providers for SQL Server and text files. You can also create custom log providers and use them for logging.
Incorrect:
Not A: The destination is a SQL Server database, not a text file.
References: Integration Services (SSIS) Packages

QUESTION 238
You work for an organization with global operations.
You are responsible for the SQL Server 2008 Integration Services (SSIS) instance.
You develop SSIS packages to load daily and weekly feeds.
These packages are deployed via the SQL Server method.
The servers reside in geographies with a high risk of natural disaster.
You need to implement a disaster recovery plan to back up the SSIS packages for availability.
What should you back up?

A.    The model database
B.    The package folder
C.    The master database
D.    The MSDB database

Answer: D

QUESTION 239
You maintain a SQL Server 2008 Integration Services (SSIS) instance.
You develop a package that creates the temporary table *employee_stgl and then loads the data from an Excel source data flow task into *employee_stgl by using conditional transformation splits. The package then loads the data into a destination table.
When you try to open the package, you get an error that reads,
“Invalid object name #employee_stgl.”
You need to resolve this error message.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.    Set RetainSameConnection to True.
B.    Set RetainSameConnection to False.
C.    Set DelayValidation to True.
D.    Set DelayValidation to False.

Answer: AC
Explanation:
A: ConnectionManagerOleDbClass.RetainSameConnection Property Gets or sets a Boolean that indicates whether the connection manager retains the same connection.
C: DtsContainer.DelayValidation Property
Gets or sets a Boolean that indicates whether validation of the task is delayed until run time.
The default value is false.
Note: Validating the package before it runs is a way of finding some errors before execution starts. However, it processes the package to find errors, and if no errors are found, the package runs. Because this goes through the package two times, validating a package increases the amount of processing for the package, so should be used only when necessary.

QUESTION 240
You maintain a SQL Server 2008 Integration Services (SSIS) instance.
You use the Execute SQL task to create a table in a Control Flow. Following the Execute SQL task is a Data Flow task in which an OLE DB source component uses this table.
The package fails during runtime.
You need to delay the validation of a task in the Control Flow and the OLE DB source in the data flow.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.    Set the DelayValidation property for the Control Flow task to True.
B.    Set the ValidateExternalMetaData property for the OLE DB source to False.
C.    Set the ValidateExternalMetaData property for the OLE DB source to True.
D.    Set the DelayValidation property for the Control Flow task to False.

Answer: AB
Explanation:
The DelayValidation property is available only in executables (e.g., Control Flow tasks, the package itself). The property isn’t available in data flow components. If you want to change the behavior of a specific data flow component, you must set its ValidateExternalMetadata property to False.
