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.4 You are designing a data warehouse for a software distribution business that stores sales by software
title.It stores sales targets by software category.Software titles are classified into subcategories and
categories.Each software title is included in only a single software subcategory, and each subcategory is
included in only a single category.The data warehouse will be a data source for an Analysis Services
cube.
The data warehouse contains two fact tables:
factSales, used to record daily sales by software title
factTarget, used to record the monthly sales targets by software category
Reports must be developed against the warehouse that reports sales by software title, category and
subcategory, and sales targets.
You need to design the software title dimension.The solution should use as few tables as possible while
supporting all the requirements.
What should you do?
A.Create three software tables, dimSoftware, dimSoftwareCategory.and dimSoftwareSubcategory and a
fourth bridge table that joins software titles to their appropriate category and subcategory table records
with foreign key constraints.Direct the cube developer to use key granularity attributes.
B.Create three software tables, dimSoftware, dimSoftwareCategory, and
dimSoftwareSubcategory.Connect factSales to all three tables and connect factTarget to
dimSoftwareCategory with foreign key constraints.Direct the cube developer to use key granularity
attributes.
C.Create one table, dimSoftware, which contains Software Detail, Category, and Subcategory
columns.Connect factSales to dimSoftware with a foreign key constraint.Direct the cube developer to use
a non-key granularity attribute for factTarget.
D.Create two tables, dimSoftware and dimSoftwareCategory.Connect factSales to dimSoftware and
factTarget to dimSoftwareCategory with foreign key constraints.Direct the cube developer to use key
granularity attributes.

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:
NO.12 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.13 You are designing a data warehouse hosted on SQL Azure.The data warehouse currently includes the
dimUser 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.Add a district column to the dimUser table.
B.Partition the factSales table on the district column.
C.Create a userDistrict table that contains primary key columns from the dimUser and dimDistrict tables.

named Quotes.The table has no indexes and consists of seven columns:
[ID]
[QuoteDate]
[Open]
[Close]

[Low]
[Volume]
Each of the following queries must be able to use a columnstore index:
SELECT AVG ([Close]) AS [AverageClose] FROM Quotes WHERE [QuoteDate] BETWEEN '20100101'
AND '20101231'.
SELECT AVG([High] - [Low]) AS [AverageRange] FROM Quotes WHERE [QuoteDate] BETWEEN

NO.15 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.
