Q22. You are designing a partitioning strategy for a large fact table in a data warehouse. Tens of millions of new records are loaded into the data warehouse weekly, outside of business hours.
Most queries are generated by reports and by cube processing. Data is frequently queried at the day level and occasionally at the month level.

Answer: D
Q23. You are developing a SQL Server Integration Services (SSIS) package to load data into a Windows Azure SQL Database database. The package consists of several data flow tasks.
The package has the following auditing requirements:

✑ The T-SQL script must be executed only once per data flow task that fails, regardless of the nature of the error.
You need to ensure that auditing is configured to meet these requirements. 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.

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.va!idate_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 OnTaskFailed event text to the table.
Answer: C
Q24. You are designing an extract, transform, load (ETL) process for loading data from a SQL Server database into a large fact table in a data warehouse each day with the prior day's sales data.
The ETL process for the fact table must meet the following requirements:
✑ Load new data in the shortest possible time.
✑ Remove data that is more than 36 months old.
✑ Ensure that data loads correctly.
✑ Minimize record locking.
✑ Minimize impact on the transaction log.
You need to design an ETL process that meets the requirements. What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Partition the destination fact table by date. Insert new data directly into the fact table and delete old data directly from the fact table.
B. Partition the destination fact table by date. Use partition switching and staging tables both to remove old data and to load new data.
C. Partition the destination fact table by customer. Use partition switching both to remove old data and to load new data into each partition.
D. Partition the destination fact table by date. Use partition switching and a staging table to remove old data. Insert new data directly into the fact table.
Answer: B
Q25. You are developing a SQL Server Integration Services (SSIS) project that copies a large amount of rows from a SQL Azure database. The project uses the Package Deployment Model. This project is deployed to SQL Server on a test server.
You need to ensure that the project is deployed to the SSIS catalog on the production server.
What should you do?
A. Open a command prompt and run the dtexec /dumperror /conn command.
B. Create a reusable custom logging component and use it in the SSIS project.
C. Open a command prompt and run the gacutil command.
D. Add an OnError event handler to the SSIS project.
E. Open a command prompt and execute the package by using the SQL Log provider and running the dtexecui.exe utility.
F. Open a command prompt and run the dtexec /rep /conn command.
G. Open a command prompt and run the dtutil /copy command.
H. Use an msi file to deploy the package on the server.
I. Configure the SSIS solution to use the Project Deployment Model.
J. Configure the output of a component in the package data flow to use a data tap.
K. Run the dtutil command to deploy the package to the SSIS catalog and store the configuration in SQL Server.
Answer: I

Q26. DRAG DROP
You use SQL Server Integration Services (SSIS) for extract, transformation, load (ETL) processing.
Issues concerning addresses are discovered in the data warehouse that you manage. Validation must separate the addresses into three categories:
✑ Valid addresses
✑ Autocorrected addresses
✑ Invalid addresses
You need to enhance the SSIS packages to perform address validation by using an external service.
Which transformation should you use? (To answer, drag the appropriate transformation from the list of options to the correct location or locations in the answer area.)
