You are editing a SQL Server Integration Services (SSIS) package that contains a task with a sensitive
property.
You need to create a project parameter and configure it so that its value is encrypted when it is deployed
to the SSIS catalog.
Which three steps should you perform in sequence? (To answer, move the appropriate actions from the
list of actions to the answer area and arrange them in the correct order.)
Answer:
NO.2 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.
Answer: B

A SQL Server Integration Services (SSIS) package named DataFeed interacts with an external vendor
data feed.The package is executed several times a day, either as part of other packages' control flow or
by itself.The external data feed is unreliable because network failures and slow response times are
frequent.The package is currently deployed on the file system.
To analyze the reliability of the external data feed, you must collect execution data.Every time the
DataFeed package is executed, the following information must be logged:
Start Time
End Time
Execution Result
Execution Duration
You need to design a logging solution that meets the requirements by using the least amount of
administrative and development effort.
Which three actions should you perform in sequence? (To answer, move the appropriate actions from the
list of actions to the answer area and arrange them in the correct order.)
Answer:

What should you do?
A.Create a time mapping table.
B.Change the level of granularity in both fact tables to be the same.
C.Merge the fact tables.
D.Create a view on the sales table.

all dimensional data from the three original solutions is represented.
What should you do?
A.Create a junk dimension for the geography dimension.
