Q11. You are a data warehouse developer responsible for developing data cleansing processes.
Duplicate employees exist in an employee dimension.
You need to map, discover, and manage domain values based on the employee
Which Data Quality Services (DQS) option should you use? (To answer, select the appropriate option in the answer area.)
Q12. A SQL Server Integration Services (SSIS) package imports daily transactions from several files into a SQL Server table named Transaction. Each file corresponds to a different store and is imported in parallel with the other files. The data flow tasks use OLE DB destinations in fast load data access mode.
The number of daily transactions per store can be very large and is growing- The Transaction table does not have any indexes.
You need to minimize the package execution time.
What should you do?
A. Partition the table by day and store.
B. Create a clustered index on the Transaction table.
C. Run the package in Performance mode.
D. Increase the value of the Row per Batch property.
Explanation: * Data Access Mode – This setting provides the 'fast load' option which internally uses a BULK INSERT statement for uploading data into the destination table instead of a simple INSERT statement (for each single row) as in the case for other options.
* BULK INSERT parameters include: ROWS_PER_BATCH =rows_per_batch Indicates the approximate number of rows of data in the data file. By default, all the data in the data file is sent to the server as a single transaction, and the number of rows in the batch is unknown to the query optimizer. If you specify ROWS_PER_BATCH (with a value > 0) the server uses this value to optimize the bulk-import operation. The value specified for ROWS_PER_BATCH should approximately the same as the actual number of rows.
Q13. 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?
B. DQS Cleansing
C. CDC Splitter
Q14. You are designing a SQL Server Integration Services (SSIS) data flow to load sales transactions from a source system into a data warehouse hosted on SQL Azure. One of the columns in the data source is named ProductCode.
Some of the data to be loaded will reference products that need special processing logic in the data flow.
You need to enable separate processing streams for a subset of rows based on the source product code.
Which data flow transformation should you use?
B. Source Assistant
C. Script Task
D. Conditional Split

Q15. You administer a Microsoft SQL Server 2012 server that has SQL Server Integration Services (SSIS) installed.
You plan to deploy new SSIS packages to the server. The SSIS packages use the Project Deployment Model together with parameters and Integration Services environment variables.
You need to configure the SQL Server environment to support these packages.
What should you do?
A. Create SSIS configuration files for the packages.
B. Create an Integration Services catalog.
C. Install Data Quality Services.
D. Install Master Data services.

Q16. You are developing a SQL Server Integration Services (SSIS) project that contains a project Connection Manager and multiple packages.
All packages in the project must connect to the same database. The server name for the database must be set by using a parameter named ParamConnection when any package in the project is executed.
You need to develop this project with the least amount of development effort.
What should you do? (Each answer presents a part of the solution. Choose all that apply.)
A. Create a package parameter named ConnectionName in each package.
B. Edit each package Connection Manager. Set the ConnectionName property to @[$Project::ParamConnection].
C. Edit the project Connection Manager in Solution Explorer. Set the ConnectionName property to @ [$Project::ParamConnection].
D. Set the Sensitive property of the parameter to True.
E. Create a project parameter named ConnectionName.
F. Set the Required property of the parameter to True.
Explanation: B: From question: " The server name for the database must be set by using a parameter named ParamConnection when any package in the project is executed."
E: SSIS 2012 has introduced the concept of Project level connection managers. An SSIS project is generally more than one package. To simplify lives, the SSIS team now allows for the sharing of common resources across projects, connection managers being one of those resources.
F: When a parameter is marked as required, a server value or execution value must be specified for that parameter. Otherwise, the corresponding package does not execute. Although the parameter has a default value at design time, it will never be used once the project is deployed.
* Integration Services (SSIS) parameters allow you to assign values to properties within packages at the time of package execution. You can create project parameters at the project level and package parameters at the package level. Project parameters are used to supply any external input the project receives to one or more packages in the project. Package parameters allow you to modify package execution without having to edit and redeploy the package.

Q17. You plan to deploy a SQL Server Integration Services (SSIS) project by using the project deployment model.
You need to monitor control flow tasks to determine whether any of them are running longer than usual. Which three actions should you perform in sequence? (To answer, move the appropriate actions from the list ofactions to the answer area and arrange them in the correct order.)
Q18. You develop a SQL Server Integration Services (SSIS) project by using the Project Deployment model.
The project contains many packages. It is deployed on a server named Development!. The project will be deployed to several servers that run SQL Server 2012.
The project accepts one required parameter. The data type of the parameter is a string.
A SQL Agent job is created that will call the master.dtsx package in the project. A job step is created for the SSIS package.
The job must pass the value of an SSIS Environment Variable to the project parameter. The value of the Environment Variable must be configured differently on each server that runs SQL Server. The value of the Environment Variable must provide the server name to the project parameter.
You need to configure SSIS on the Development1 server to pass the Environment Variable to the package.
Which four actions should you perform in sequence by using SQL Server Management Studio? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
Q19. 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.
Q20. 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?
