QUESTION 1
You develop a SQL Server Integration Services (SSIS) package that imports Windows Azure SQL Database data into a
data warehouse every night.
The Windows Azure SQL Database 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 similarity threshold to 0.40.
B. Decrease the maximum number of matches per lookup.
C. Change the similarity threshold to 0.85.
D. Increase the maximum number of matches per lookup.
Correct Answer: C
Explanation: * Similarity threshold Set the similarity threshold at the component level by using the slider. The closer the
value is to 1, the closer the resemblance of the lookup value to the source value must be to qualify as a match.
Increasing the threshold can improve the speed of matching since fewer candidate records need to be considered.

QUESTION 2
You are creating a Data Quality Services (DQS) solution. You must provide statistics on the accuracy of the data.
You need to use DQS profiling to obtain the required statistics.
Which DQS activity should you use?
A. Cleansing
B. Knowledge Discovery
C. SQL Profiler
D. Matching Rule Definition
Correct Answer: A

QUESTION 3
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains
a unique solution that might meet the stated goals. Some question sets might have more than one correct solution,
while
others might not have a correct solution.
After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not
appear in the review screen.
You have the following line-of-business solutions:
ERP system
Online WebStore
Partner extranet
One or more Microsoft SQL Server instances support each solution. Each solution has its own product catalog. You
have an additional server that hosts SQL Server Integration Services (SSIS) and a data warehouse. You populate the
data
warehouse with data from each of the line-of-business solutions. The data warehouse does not store primary key values
from the individual source tables.
The database for each solution has a table named Products that stored product information. The Products table in each
database uses a separate and unique key for product records. Each table shares a column named ReferenceNr
between
the databases. This column is used to create queries that involve more than once solution.
You need to load data from the individual solutions into the data warehouse nightly. The following requirements must be
met:
If a change is made to the ReferenceNr column in any of the sources, set the value of IsDisabled to True and create a
new row in the Products table.
If a row is deleted in any of the sources, set the value of IsDisabled to True in the data warehouse.
Solution: Perform the following actions:
Enable the Change Tracking feature for the Products table in the three source databases.
Query the CHANGETABLE function from the sources for the deleted rows.
Set the IsDIsabled column to True on the data warehouse Products table for the listed rows.
Does the solution meet the goal?
A. Yes
B. No
Correct Answer: B
We must check for updated rows, not just deleted rows.

QUESTION 4
You are developing a SQL Server Integration Services (SSIS) package to load data into a data warehouse. The
package consists of several data flow tasks.
The package experiences intermittent errors in the data flow tasks.
If any data flow task fails, all package error information must be captured and written to a SQL Server table by using an
OLE DB connection manager.
You need to ensure that the package error information is captured and written to the table.
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.
Correct Answer: I

QUESTION 5

You need re ensure that the job loads changes from the previous week.
Which stored procedure should you execute?
A. catalog.deploy_project
B. catalog.restore_project
C. catalog.stop.operation
D. sys.sp_cdc.addJob
E. sys.sp.cdc.changejob
F. sys.sp_cdc_disable_db

QUESTION 6
You have a database named DB1. You create a Microsoft SQL Server Integration Services (SSIS) package that
