You develop a SQL Server Integration Services (SSIS) package that imports SQL Azure data into a data
warehouse every night.
The SQL Azure 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.
Change the similarity threshold to 0.55.
C.
Change the similarity threshold to 0.40.
D.
Increase the maximum number of matches per lookup.

QUESTION 33
Drag and Drop Questions
You are developing a SQL Server Integration Services (SSIS) package to insert new data into a data mart.
The package uses a Lookup transformation to find matches between the source and destination. The data flow has the following requirements:
– New rows must be inserted.
– Lookup failures must be written to a flat file.
In the Lookup transformation, the setting for rows with no matching entries is set to Redirect rows to no match output.
You need to configure the package to direct data into the correct destinations.
How should you design the data flow outputs? (To answer, drag the appropriate transformation from the list of answer options to the correct location in the answer area.)
