slightly different in each data mart.
You need to design a consolidated dimensional structure that will be easy to maintain while ensuring that
all dimensional data from the three original solutions is represented.
What should you do?

NO.4 You are reviewing the design of an existing fact table named factSales, which is loaded from a SQL
Azure database by a SQL Server Integration Services (SSIS) package each day.The fact table has
approximately 1 billion rows and is dimensioned by product, sales date, and sales time of day.
The database administrator is concerned about the growth of the database.Users report poor reporting
performance against this database.Reporting requirements have recently changed and the only
remaining report that uses this fact table reports sales by product name, sale month, and sale year.No
other reports will be created against this table.
You need to reduce the report processing time and minimize the growth of the database.
What should you do?
A.Partition the table by product type.
B.Create a view over the fact table to aggregate sales by month.
C.Change the granularity of the fact table to month.
D.Create an indexed view over the fact table to aggregate sales by month.

NO.7 DRAG DROP
A new SQL Server Integration Services (SSIS) project is deployed to the SSIS catalog.
To troubleshoot some data issues, you must output the data streaming through several data flows into text
files for further analysis.You have the list of data flow package paths and identification strings of the
various task components that must be analyzed.
You need to create these output files with the least amount of administrative and development effort.
Which three stored procedures should you execute 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.8 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
