Q24. DRAG DROP
A new dedicated server is used to execute resource-intensive SQL Server Integration Services (SSIS) 2021 packages. The environment that you are deploying the packages to has the following constraints:
✑ The operating system is Windows Server 2008 R2.
✑ The SSIS packages are stored in the SSIS catalog.
✑ Some of these SSIS packages use 32-bit custom components.
You need to install only the components that are required to deploy and run the packages on the new server.
Which three 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.)
Answer:
Explanation:
Note: Step 1:
Step 2:
If you require 32-bit versions of the Integration Services runtime and tools to run certain packages in 32-bit mode, you must also install SQL Server Data Tools (SSDT).
Note:
For a complete installation of Integration Services, together with the tools and documentation for developing and managing packages, select both Integration Services and the following Shared Features:
* SQL Server Data Tools to install the tools for designing packages.
* Management Tools - Complete to install SQL Server Management Studio for managing packages.
* Client Tools SDK to install managed assemblies for Integration Services programming.
Step 3: How to Modify the Service Configuration File to Connect to a Named Instance of SQL Server
To connect to a named instance of SQL Server, you must modify the service configuration file, MsDtsSrvr.ini.xml.
Q25. DRAG DROP
You are designing a SQL Server Integration Services (SSIS) package. The package moves order-related data to a staging table named Order. Every night the staging data is truncated and then all the recent orders from the online store database are inserted into the staging table.
Your package must meet the following requirements:
•If the truncate operation fails, the package execution must stop and report an error.
•If the Data Flow task that moves the data to the staging table fails, the entire refresh operation must be rolled back.
•For auditing purposes, a log entry must be entered in a SQL log table after each execution of the Data Flow task.
The TransactionOption property for the package is set to Required. You need to design the package to meet the requirements.
How should you design the control flow for the package? (To answer, drag the appropriate setting from the list of settings to the correct location or locations in the answer area.)

Q26. 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.
Answer: D
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.
Q27. 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. Option A
B. Option B
C. Option C
D. Option D
Answer: D

Q28. You are developing a SQL Server Integration Services (SSIS) project with multiple packages to copy data to a Windows Azure SQL Database database.
An automated process must validate all related Environment references, parameter data types, package references, and referenced assemblies. The automated process must run on a regular schedule.
You need to establish the automated validation process by using the least amount of administrative effort.
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.
Answer: N
Q29. You are developing a data flow transformation to merge two data sources. One source contains product data and the other source contains data about the country in which the product was manufactured. Both data sources contain a two-character CountryCode column and both use SQL Server. Both data sources contain an ORDER BY clause to sort the data by the CountryCode column in ascending order.
You use a Merge Join transformation to join the data.
You need to ensure that the Merge Join transformation works correctly without additional transformations.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)
A. Change the ORDER BY clause on the product source to order by ProductName.
B. Change the Merge Join transformation to a Merge transformation.
C. Set the appropriate SortKeyPosition properties on the data sources.
D. Set the IsSorted property on both data sources.
Answer: C,D
Q30. DRAG DROP
You are developing a SQL Server Integration Services (SSIS) package.
The package uses custom functionality that accesses a SQL Server database. The custom functionality must be implemented by using Language Integrated Query (LINQ).
You need to ensure that the LINQ code can be debugged at design time.
What should you select from the SSIS Toolbox? (To answer, drag the appropriate item to the correct location in the answer area.)
