Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 2 Sample Questions:
You are developing a SQL Server Integration Services (SSIS) project by using the Project Deployment model. A package in the project extracts data from a Windows Azure SQL Database database. The package is deployed to SQL Server.
The package is not producing the desired results.
You need to generate the .mdmp and .tmp debug files in order to troubleshoot the issues.
What should you do?
- A. Execute the catalog.add_data_tap stored procedure with the package execution_id.
- B. Run the DTEXEC utility with the /Logger option.
- C. Execute the catalog.create_execution_dump stored procedure with the package execution_id.
- D. Run the DTEXEC utility with the /Reporting V option.
Correct Answer: C 🗳️
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 similarity threshold to 0.55.
- B. Change the similarity threshold to 0.40.
- C. Decrease the maximum number of matches per lookup.
- D. Change the Exhaustive property to True.
Correct Answer: A 🗳️
