Q111. You are designing a SQL Server Integration Services (SSIS) solution. The solution will contain an SSIS project that includes several SSIS packages. Each SSIS package will define the same connection managers and variables.
You have the following requirements:
. Ensure that the deployment model supports changing the content of connection strings by using parameters at execution time.
. Ensure that the deployment model automatically starts from calls to the catalog.start_execution stored procedure in the SSISDB database.
. Maximize performance at execution time.
. Minimize development effort.
You need to design a solution that meets the requirements.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Use a project deployment model. Modify connection manager properties to use project parameters. Ensure that the SSISDB database is created.
B. Use a project deployment model. Configure connections in an XML configuration file referenced by an environment variable that corresponds to the SQL Server environment of each SSIS package.
C. Use a package deployment model. Use a SQL Server package configuration with a common filter. Change the contents of the SSIS Configurations table at runtime.
D. Use a package deployment model. Save each SSIS package to a file share that can be accessed from all environments.
Answer: A
Q112. You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy. The package reads data from a source system that uses the SQL Server change data capture (CDC) feature.
You have added a CDC Source component to the data flow to read changed data from the source system.
You need to add a data flow transformation to redirect rows for separate processing of insert, update, and delete operations.
Which data flow transformation should you use?
A. Audit
B. DQS Cleansing
C. CDC Splitter
D. Pivot
Answer: D
Q113. You are designing a data warehouse with two fact tables. The first table contains sales per month and the second table contains orders per day.
Referential integrity must be enforced declaratively.
You need to design a solution that can join a single time dimension to both fact tables.
What should you do?
A. Create a view on the sales table.
B. Partition the fact tables by day.
C. Create a surrogate key for the time dimension.
D. Change the level of granularity in both fact tables to be the same.
Answer: D
Explanation: In order to join the facts table in time dimension we cannot have two different time measures (time and day).
Q114. 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.)
Answer:
Q115. You are maintaining a Data Quality Services (DQS) environment. The production server failed and a new server has been set up. The DQS databases are restored to a new server. All the appropriate permissions are granted.
DQS users are experiencing issues connecting to the new Data Quality Server.
You need to enable users to connect to the new server.
Which Surface Area Configuration property should you enable?
A. AdHocRemoteQueriesEnabled
B. SoapEndpointsEnabled
C. ClrIntegrationEnabled
D. RemoteDacEnabled
E. OleAutomationEnabled
F. XpCmdShellEnabled
Answer: C
Q116. You are designing a fact table in a SQL Server database.
The fact table must meet the following requirements:
Include a columnstore index.
Allow users to choose up to 10 dimension tables and up to five facts at one time.
Maximize performance of queries that aggregate measures by using any of the 10
dimensions.
Support billions of rows.
Use the most efficient design strategy.
You need to design the fact table to meet the requirements. What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Design a fact table with 5 dimensional key columns and 10 measure columns. Place the columnstore index on the dimensional key columns.
B. Design a fact table with 5 dimensional key columns and 10 measure columns. Place the columnstore index on the measure columns.
C. Design a fact table with 10 dimensional key columns and 5 measure columns. Place the columnstore index on the dimensional key columns and the measure columns.
D. Design a fact table with 10 dimensional key columns and 5 measure columns. Place the columnstore index on only the measure columns.
Answer: C
Q117. You are developing a SQL Server Integration Services (SSIS) package.
You need to design a package to change a variable value during package execution by using the least amount of development effort.
What should you use?
A. Expression task
B. Script task
C. Execute SQL task
D. Execute Process task
E. Term Extraction transformation
Answer: A

Q118. You are designing a data warehouse with two fact tables. The first table contains sales per month and the second table contains orders per day.
Referential integrity must be enforced declaratively.
You need to design a solution that can join a single time dimension to both fact tables.
What should you do?
A. Create a time mapping table.
B. Change the level of granularity in both fact tables to be the same.
C. Merge the fact tables.
D. Create a view on the sales table.
Answer: C
Q119. You are developing a SQL Server Integration Services (SSIS) package that imports data into a data warehouse hosted on SQL Azure.
The package uses a Foreach container to process text files found in a folder. The package must be deployed to a single server by using the Project Deployment model.
Multiple SQL Server Agent jobs call the package. Each job is executed on a different schedule.
Each job passes a different folder path to the package.
You need to configure the package to accept the folder path from each job.
Which package configuration should you use?
A. Parent Package Variable
B. XML Configuration File
C. Environment Variable
D. .dtsConfig file
E. Registry Entry
Answer: C
Q120. 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.
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.
Incorrect:
* Maximum number of matches to output per lookup
Specify the maximum number of matches the transformation can return for each input row.
The default is 1.
