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
Correct Answer: A
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.)
Use a project deployment model. Modify connection manager properties to use project parameters. Ensure that the SSISDB database is created.
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.
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.
Use a package deployment model. Save each SSIS package to a file share that can be accessed from all environments.
Correct Answer: A
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 conformed dimension for the geography dimension.
B. Implement change tracking.
C. Create a degenerate dimension for the geography dimension.
D. Create a Type 2 slowly changing dimension for the geography dimension.
Correct Answer: A
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 Windows Azure SQL Database. 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?
A. Source Assistant
B. Destination Assistant
D. Script Component
Correct Answer: D
Explanation: Script Component Transformation:
The transformation that uses script to extract, transform, or load data.
* SQL Server Integration Services provides three different types of data flow components:
sources, transformations, and destinations. Sources extract data from data stores such as tables and views in relational databases, files, and Analysis Services databases. Transformations modify, summarize, and clean data. Destinations
load data into data stores or create in-memory datasets.
Not A, Not B: No Data Transforms called Source Assistant or Destination Assistant Not C: Not related to auditing
You maintain a SQL Server Integration Services (SSIS) package. The package was developed by using SQL Server 2008 Business Intelligence Development Studio (BIDS).
The package includes custom scripts that must be upgraded.
You need to upgrade the package to SQL Server 2016.
Which tool should you use?
A. SQL Server Integration Services Deployment Wizard
B. SQL Server Configuration Manager
C. SSIS Upgrade Wizard in SQL Server Management Studio
D. SSIS Upgrade Wizard in SQL Server 2008 BIDS
Correct Answer: C
Explanation: You can upgrade packages that were created in earlier versions of Integration Services to the Integration Services format that SQL Server 2016 uses. SQL Server provides the SSIS Package Upgrade Wizard to help in this
process. Because you can configure the wizard to backup up your original packages, you can continue to use the original packages if you experience upgrade difficulties.
You can run the SSIS Package Upgrade Wizard from SQL Server Data Tools (SSDT), from SQL Server Management Studio, or at the command prompt.
* When you upgrade an instance of SQL Server 2005 or SQL Server 2008 to the current release of SQL Server, your existing SQL Server 2008 Integration Services (SSIS) packages are not automatically upgraded to the package format that the current release SQL Server Integration Services uses. You will have to select an upgrade method and manually upgrade your packages.

Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You are a database administrator for an e-commerce company that runs an online store. The company has the databases described in the following table.
Product prices are updated and are stored in a table named Products on DB1. The Products table is deleted and refreshed each night from MDS by using a Microsoft SQL Server Integration Services (SSIS) package. None of the data sources
You need to update the SSIS package to add current prices to the Products table.
What should you use?
A. Lookup transformation
B. Merge transformation
C. Merge Join transformation
D. MERGE statement
E. Union All transformation
F. Balanced Data Distributor transformation
G. Sequential container
H. Foreach Loop container
Correct Answer: D
In the current release of SQL Server Integration Services, the SQL statement in an Execute SQL task can contain a MERGE statement. This MERGE statement enables you to accomplish multiple INSERT, UPDATE, and DELETE operations in a single statement.

Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series.
Information and details provided in a question apply only to that question.
You have a database named DB1 that has change data capture enabled.
A Microsoft SQL Server Integration Services (SSIS) job runs once weekly. The job loads changes from DB1 to a data warehouse by querying the change data capture tables.
A new version of that integration Services package is released that introduces several errors in the loading process.
You need to roll back the Integration Services package to the previous version. Which stored procedure should you execute?
Correct Answer: B
catalog.restore_project restores a project in the Integration Services catalog to a previous version.
You are developing a SQL Server Integration Services (SSIS) package that imports unsorted data into a data warehouse hosted on SQL Azure. You have the following requirements:
A destination table must contain all of the data in two source tables.
Duplicate records must be inserted into the destination table.
You need to develop a data flow that imports the data while meeting the requirements.
How should you develop the data flow? (To answer, drag the appropriate transformation from the list of transformations to the correct location in the answer area.)
Select and Place:
You have a database Ihat includes a table named dbo.sales. The table contains two billion rows. You created the table by running the following Transact-SQL statement:
You run the following queries against the dbo.sales table. All of the queries perform poorly.
The ETL process that populates the table uses bulk insert to load 10 million rows each day. The process currently takes six hours to load the records.
The value of the Refund column is equal to 1 for only 0.01 percent of the rows in the table. For all other rows, the value of the Refund column is equal to 0.
You need to maximize the performance of queries and the ETL process.
Which index type should you use for each query? To answer, select the appropriate index types in the answer area.
NOTE: Each correct selection is worth one point.
