Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 2 Sample Questions:
You are developing a SQL Server Integration Services (SSIS) package.
The package uses a data flow task to source data from a SQL Server database for loading into a dimension table in a data warehouse.
You need to create a separate data flow path for data that has been modified since it was last processed.
Which data flow components should you use to identify modified data? (Each correct answer presents a complete solution. Choose all that apply.)
- A. Aggregate
- B. Multicast
- C. Data Conversion
- D. Lookup
- E. Slowly Changing Dimension
Correct Answer: B,D 🗳️
You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN).
The financial database has the following characteristics:
- A data file of 2 terabytes is located on a dedicated LUN (drive D).
- A transaction log of 10 GB is located on a dedicated LUN (drive E).
- Drive D has 1 terabyte of free disk space.
- Drive E has S GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database.
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You implement log shipping of the financial database to another SQL Server 2012 instance. You decide to failoverto this secondary database.
You need to ensure that all transactions will be replicated to the secondary database.
Which backup option should you use?
- A. NO_CHECKSUM
- B. SIMPLE
- C. SKIP
- D. CHECKSUM
- E. Transaction log
- F. NORECOVERY
- G. BULK_LOGGED
- H. FULL
- I. CONTINUE_AFTER_ERROR
- J. RESTART
- K. Differential
- L. STANDBY
- M. COPY_ONLY
- N. DBO_ONLY
Correct Answer: F 🗳️
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. Run the package in Performance mode.
- C. Reduce the value of the Maximum Insert Commit Size property.
- D. Create a clustered index on the Transaction table.
Correct Answer: A 🗳️
Explanation: Only visible for Lead2Passed members. You can sign-up / login (it's free).
You are developing a SQL Server Integration Services (SSIS) package to load data into a data warehouse. The package consists of several data flow tasks.
The package experiences intermittent errors in the data flow tasks.
If any data flow task fails, all package error information must be captured and written to a SQL Server table by using an OLE DB connection manager.
You need to ensure that the package error information is captured and written to the table.
What should you do?
- A. Deploy the project by using dtutil.exe with the /COPY SQL option.
- B. View the All Messages subsection of the All Executions report for the package.
- C. Use an event handler for OnTaskFailed for the package.
- D. Deploy the .ispac file by using the Integration Services Deployment Wizard.
- E. Create a SQL Server Agent job to execute the SSISDB.catalog.validate_package stored procedure.
- F. Create a SQL Server Agent job to execute the SSISDB.catalog.validate_project stored procedure.
- G. Enable the SSIS log provider for SQL Server for OnError in the package control flow.
- H. Store the System::ExecutionInstanceGUID variable in the custom log table.
- I. Create a table to store error information. Create an error output on each data flow destination that writes OnError event text to the table.
- J. Deploy the project by using dtutil.exe with the /COPY DTS option.
- K. Use an event handler for OnError for the package.
- L. Store the System::ServerExecutionID variable in the custom log table.
- M. Use an event handler for OnError for each data flow task.
- N. Create a SQL Server Agent job to execute the SSISDB.catalog.create_execution and SSISDB.catalog.*tart_execution stored procedures.
- O. View the job history for the SQL Server Agent job.
- P. Store the System::SourceID variable in the custom log table.
- 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.
- R. Enable the SSIS log provider for SQL Server for OnTaskFailed in the package control flow.
Correct Answer: G 🗳️
