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.2 You develop and deploy a SQL Server Integration Services (SSIS) package.
The package is stored in the file system.
You need to execute the package without importing it to the SSIS server.
What should you use to execute the package? (Each correct answer presents a complete
solution.Choose all that apply.)
A.catalog.start_package
B.dtexec
C.SQL Server Management Studio
D.SQL Server Agent

NO.3 You are designing an enterprise star schema that will consolidate data from three independent data
marts.One of the data marts is hosted on SQL Azure.
Most of the dimensions have the same structure and content.However, the geography dimension is
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?
A.Create a junk dimension for the geography dimension.
B.Implement change data capture.
C.Create a conformed dimension for the geography dimension.
D.Create three geography dimensions.

NO.4 You are implementing the indexing strategy for a fact table in a data warehouse.The fact table is
named Quotes.The table has no indexes and consists of seven columns:
[ID]
[QuoteDate]
[Open]
[Close]
[High]
[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
'20100101' AND
'20101231'.
SELECT SUM([Volume]) AS [SumVolume] FROM Quotes WHERE [QuoteDate] BETWEEN '20100101'
AND '20101231'.
You need to ensure that the indexing strategy meets the requirements.The strategy must also minimize
the number and size of the indexes.
What should you do?
A.Create one columnstore index that contains [ID], [Close], [High], [Low], [Volume], and [QuoteDate].
B.Create three coiumnstore indexes:
One containing [QuoteDate] and [Close]
One containing [QuoteDate], [High], and [Low]
One containing [QuoteDate] and [Volume]
C.Create one columnstore index that contains [QuoteDate], [Close], [High], [Low], and [Volume].
D.Create two columnstore indexes:
One containing [ID], [QuoteDate], [Volume], and [Close]
One containing [ID], [QuoteDate], [High], and [Low]

A SQL Server Integration Services (SSIS) project has been deployed to the SSIS catalog.The project
includes a project Connection Manager to connect to the data warehouse.The SSIS catalog includes two
Environments:
Development
QA
Each Environment defines a single Environment Variable named ConnectionString of type string.The
value of each variable consists of the connection string to the development or QA data warehouses.
You need to be able to execute deployed packages by using either of the defined Environments.
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.6 You are developing a project that contains multiple SQL Server Integration Services (SSIS)
packages.The packages will be deployed to the SSIS catalog.One of the steps in each package accesses
an FTP site to download sales transaction data.
You create project parameters to store the username and password that are used to access the FTP site.
You need to ensure that the username and password values are encrypted when they are deployed.
What should you do?
A.set the Sensitive property of the parameters to True.
B.Set the ProtectionLevel property of the package to EncryptSensitiveWithUserKey.
C.Change the parameters to package parameters.
D.Change the project to the Legacy Deployment model.

NO.7 You are developing a SQL Server Integration Services (SSIS) project that copies a large amount of
rows from a SQL Azure database.The project uses the Package Deployment Model.This project is
deployed to SQL Server on a test server.
You need to ensure that the project is deployed to the SSIS catalog on the production server.
What should you do?
A.Open a command prompt and run the dtexec /dumperror /conn command.
B.Create a reusable custom logging component and use it in the SSIS project.
C.Open a command prompt and run the gacutil command.
D.Add an OnError event handler to the SSIS project.
E.Open a command prompt and execute the package by using the SQL Log provider and running the
dtexecui.exe utility.
F.Open a command prompt and run the dtexec /rep /conn command.
G.Open a command prompt and run the dtutil /copy command.
H.Use an msi file to deploy the package on the server.
I.Configure the SSIS solution to use the Project Deployment Model.
J.Configure the output of a component in the package data flow to use a data tap.
K.Run the dtutil command to deploy the package to the SSIS catalog and store the configuration in SQL
Server.

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
