You are designing an extract, transform, load (ETL) process with SQL Server Integration Services (SSIS).
Two packages, Package A and Package B, will be designed.
Package A will execute Package B.
Both packages must reference a file path corresponding to an input folder where files will be located for further processing.
You need to design a solution so that the file path can be easily configured with the least administrative and development effort.
Which four 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.)

QUESTION 32
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.

You must configure the SQLStatement property of the Execute SQL task.
Which SQL statement should you use?

A.    INSERT INTO dbo.Table (variablevalue) VALUES ($Project::StringVar)
B.    INSERT INTO dbo.Table (variablevalue) VALUES (@StringVar)
C.    INSERT INTO dbo.Table (variablevalue) VALUES ($Package::StringVar)
D.    INSERT INTO dbo.Table (variablevalue) VALUES (?)

QUESTION 35
You are developing a SQL Server Integration Services (SSIS) project by using the Project Deployment Model.
The project is deployed to a single SSIS catalog, and transfers data to and from multiple databases hosted on SQL Server.
The project must be configured to be able to export data to and from five different production servers that run SQL Server 2012. Each target server requires different values for connection strings and parameters in the SSIS project.
You need to meet the requirements by using the least amount of administrative effort.
What should you do?

A.    For each target server, create separate Environments in the SSIS catalog of the host
SQL Server SSIS instance.
Select the appropriate Environment at package execution time.
B.    Create one SSIS catalog Environment.
Change the values of each Environment variable at package execution time.
C.    For each target server, create separate registry entry configurations.
Select the registry entry at package execution time.
D.    For each target server, create a separate XML configuration file.
Select the XML configuration file at package execution time.

Answer: A

QUESTION 36
You are developing a SQL Server Integration Services (SSIS) package that imports data from a relational database to a data warehouse.
You are importing data from a relational table named Projects.
The table has change data capture enabled on all columns.
You need to process only the most recent values from rows that have been inserted or updated since the previous execution of the package.
Which query should you use as the data source?

A.    SELECT * FROM cdc.fn_cdc_get_all_changes_Projects (@from_lsn, @to_lsn, N’ all update old’)
B.    SELECT * FROM cdc.fn_cdc_get_all_changes_Projects (@from_lsn, @to_lsn, N’ all’)
C.    SELECT * FROM cdc.fn_cdc_get_net_changes_Projects (@from_lsn, @to_lsn)
D.    SELECT * FROM cdc.Projects_CT WHERE @from_lsn >= _$start_lsn AND @to_lsn < _$start_lsn
