QUESTION 44
You are creating a SQL Server Master Data Services (MDS) mode).
This model is used to store a master list of products. An attribute must be added to the Product entity to define the sales manager responsible for each product.
You need to create an attribute in the Product entity that prevents users from entering invalid sales manager values.

D.    Parent
E.    Explicit
F.    Recursive

Answer: B

QUESTION 45
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.    Decrease the maximum number of matches per lookup.
B.    Change the similarity threshold to 0.55.
C.    Change the Exhaustive property to True.
D.    Increase the maximum number of matches per lookup.

Answer: B
Explanation:
The similarity thresholds can be set at the component and join levels.
The join-level similarity threshold is only available when the transformation performs a fuzzy match between columns in the input and the reference table.
The similarity range is 0 to 1. The closer to 1 the threshold is, the more similar the rows and columns must be to qualify as duplicates.

QUESTION 46
You are designing a data warehouse hosted on SQL Azure.
The data warehouse currently includes the dimllser and dimDistrict dimension tables and the factSales fact table. The dimUser table contains records for each user permitted to run reports against the warehouse, and the dimDistrict table contains information about sales districts.
The system is accessed by users from certain districts, as well as by area supervisors and users from the corporate headquarters.
You need to design a table structure to ensure that certain users can see sales data for only certain districts.
Some users must be permitted to see sales data from multiple districts.
What should you do?

A.    Create a userDistrict table that contains primary key columns from the dimUser and dimDistrict tables.
B.    Partition the factSales table on the district column.
C.    Add a district column to the dimUser table.
D.    For each district, create a view of the factSales table that includes a WHERE clause for the district.

Answer: A

QUESTION 47
Drag and Drop Question
You are creating a sales data warehouse.
When a product exists in the product dimension, you update the product name.
When a product does not exist, you insert a new record.
In the current implementation, the DimProduct table must be scanned twice, once for the insert and again for the update.
As a result, inserts and updates to the DimProduct table take longer than expected.
You need to create a solution that uses a single command to perform an update and an insert. How should you use a MERGE T-SQL statement to accomplish this goal? (To answer, drag the appropriate answer choice from the list of options to the correct location or locations in the answer area. You may need to drag the split bar between panes or scroll to view content.)
