You have added a CDC Source component to the data flow to read changed data from the source system.
You need to add a data flow transformation to redirect rows for separate processing of insert, update, and delete operations.
Which data flow transformation should you use?
- A. Merge
- B. Audit
- C. Pivot
- D. CDC Splitter
Correct Answer: A 🗳️
Explanation: Only visible for TestBraindump members. You can sign-up / login (it's free).

- B. Install ADOMD.NET.
- C. Run the DQSInstaller.exe command.
- D. Run the Configuration component in the Data Quality Client.
Correct Answer: C 🗳️
You are designing a SQL Server Integration Services (SSIS) data flow to load sales transactions from a source system into a data warehouse hosted on Windows Azure SQL Database. One of the columns in the data source is named ProductCode.
Some of the data to be loaded will reference products that need special processing logic in the data flow.
You need to enable separate processing streams for a subset of rows based on the source product code.
Which Data Flow transformation should you use?
- A. Source Assistant
- B. Conditional Split
- C. Script Task
- D. Multicast
Correct Answer: C 🗳️
Explanation: Only visible for TestBraindump members. You can sign-up / login (it's free).
You develop a SQL Server Integration Services (SSIS) package that imports Windows Azure SQL Database data into a data warehouse every night.
The Windows Azure SQL Database data contains many misspellings and variations of abbreviations. To import the data, a developer used the Fuzzy Lookup transformation to choose the closest-matching string from a reference table of allowed values. The number of rows in the reference table is very large.
If no acceptable match is found, the Fuzzy Lookup transformation passes a null value. The current setting for the Fuzzy Lookup similarity threshold is 0.50.
Many values are incorrectly matched.
You need to ensure that more accurate matches are made by the Fuzzy Lookup transformation without degrading performance.
What should you do?
- A. Change the Exhaustive property to True.
- B. Decrease the maximum number of matches per lookup.
- C. Change the similarity threshold to 0.40.
- D. Change the similarity threshold to 0.55.
Correct Answer: D 🗳️
