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.
