Q71. 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

Which type of attribute should you create?
A. Recursive
B. Explicit
C. Domain-based

Q73. DRAG DROP
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:
✑ Test
✑ Production
Each Environment defines a single Environment Variable named ConnectionString of type string. The value of each variable consists of the connection string to the test or production data warehouses.
You need 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:
Explanation:
Box 1:
Box 2:
Box 3:
We need to add references to the Test and Production environments to the project. Then we can map the variables in the project to the environment variables defined in the environments.
When you execute a package in a project that references multiple environments (Test and Production in this case), we can select which environment the package runs under.
Q74. You are writing a SQL Server Integration Services (SSIS) package that transfers data from a legacy system.
Data integrity in the legacy system is very poor. Invalid rows are discarded by the package but must be logged to a CSV file for auditing purposes.
You need to establish the best technique to log these invalid rows while minimizing the amount of development effort.
What should you do?
A. Add a data tap on the output of a component in the package data flow.
B. Deploy the package by using an msi file.
C. Run the package by using the dtexecui.exe utility and the SQL Log provider.
D. uses the dtutil /copy command.
E. Deploy the package to the Integration Services catalog by using dtutil and use SQL Server to store the configuration.
F. Create an OnError event handler.
G. uses the Project Deployment Wizard.
H. Use the gacutil command.
I. Create a reusable custom logging component.
J. Run the package by using the dtexec /rep /conn command.
K. Run the package by using the dtexec /dumperror /conn command.
Answer: A

Q75. DRAG DROP
You are building a SQL Server Integration Services (SSIS) package to load product data sourced from a SQL Azure database to a data warehouse. Before the product data is loaded, you create a batch record by using an Execute SQL task named Create Batch. After successfully loading the product data, you use another Execute SQL task named Set Batch Success to mark the batch as successful.
You need to create and execute an Execute SQL task to mark the batch as failed if either the Create Batch or Load Products task fails.
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.)

Q76. You are developing a SQL Server Integration Services (SSIS) package that imports data into a data warehouse.
You add an Execute SQL task to the control flow. The task must execute a simple INSERT statement.
The task has the following requirements:
•The INSERT statement must use the value of a string package variable. The variable name is StringVar.
•The Execute SQL task must use an OLE DB Connection Manager.
In the Parameter Mapping tab of the Execute SQL task, StringVar has been added as the only parameter.
You must configure the SQLStatement property of the Execute SQL task. Which SQL statement should you use?
A. INSERT INTO dbo.Table (variablevalue) VALUES (@StringVar)
B. INSERT INTO dbo.Table (variablevalue) VALUES ($Project::StringVar)
C. INSERT INTO dbo.Table (variablevalue) VALUES (?)
D. INSERT INTO dbo.Table (variablevalue) VALUES ($Package::StringVar)
Answer: C
Q77. You are developing a SQL Server Integration Services (SSIS) project with multiple packages to copy data to a Windows Azure SQL Database database.
An automated process must validate all related Environment references, parameter data types, package references, and referenced assemblies. The automated process must run on a regular schedule.
You need to establish the automated validation process by using the least amount of administrative effort.
What should you do?
A. Use an event handler for OnError for the package.
B. Use an event handler for OnError for each data flow task.
C. Use an event handler for OnTaskFailed for the package.
D. View the job history for the SQL Server Agent job.
E. View the All Messages subsection of the All Executions report for the package.
F. Store the System::SourceID variable in the custom log table.
G. Store the System::ServerExecutionID variable in the custom log table.
H. Store the System::ExecutionInstanceGUID variable in the custom log table.
I. Enable the SSIS log provider for SQL Server for OnError in the package control flow.
J. Enable the SSIS log provider for SQL Server for OnTaskFailed in the package control flow.
K. Deploy the project by using dtutil.exe with the /COPY DTS option.
L. Deploy the project by using dtutil.exe with the /COPY SQL option.
M. Deploy the .ispac file by using the Integration Services Deployment Wizard.
N. Create a SQL Server Agent job to execute the SSISDB.catalog.validate_project stored procedure.
O. Create a SQL Server Agent job to execute the SSISDB.catalog.validate_package stored procedure.
P. Create a SQL Server Agent job to execute the
SSISDB.catalog.create_execution and SSISDB.catalog.start_execution stored procedures.
Q. Create a table to store error information. Create an error output on each data flow destination that writes OnError event text to the table.
R. Create a table to store error information. Create an error output on each data flow destination that writes OnTaskFailed event text to the table.
Answer: N

Q79. HOTSPOT
You are developing a SQL Server Integration Services (SSIS) package. An Execute SQL task in the package checks product stock levels and sets a package variable named InStock to TRUE or FALSE depending on the stock level found.
After the successful execution of the Execute SQL task, one of two data flow tasks must run, depending on the value of the InStock variable.
You need to set the precedence constraints.
Which value for the evaluation operation should you use? (To answer, select the appropriate option for the evaluation operation in the answer area.)

Q80. DRAG DROP
You are developing a SQL Server Integration Services (SSIS) package.
The package contains several tasks that must repeat until an expression evaluates to FALSE.
You need to add and configure a container to enable this design.
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:
Explanation:
Box 1: Open the Control Flow designer of the package. Box 2: Add and edit a For Loop container.
Box 3: Configure the EvalExpression property.
Note:
* You create the control flow in a package by using the control flow designer.
Integration Services includes three types of containers that you can use in a control flow.
/ Foreach Loop container
/ For Loop container
/ Sequence container
* For Loop Container
The For Loop container defines a repeating control flow in a package. The loop implementation is similar to the For looping structure in programming languages. In each repeat of the loop, the For Loop container evaluates an expression and repeats its workflow until the expression evaluates to False.
The For Loop container uses the following elements to define the loop:
/ An optional initialization expression that assigns values to the loop counters.
/ An evaluation expression that contains the expression used to test whether the loop
should stop or continue.
/ An optional iteration expression that increments or decrements the loop counter.
