1. Note: This question is part of a series of questions that use the same set of answer choices. An answer choice may be correct for more than one question in the series.
You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a reporting database. The transactional database is updated through a web application and is operational throughout the day. The reporting database is only updated from the transactional database.
The recovery model and backup schedule are configured as shown in the following table:

One of the hard disk drives that stores the reporting database fails at 16:40 hours.
You need to ensure that the reporting database is restored. You also need to ensure that
data loss is minimal.
What should you do?

A) Restore the latest full backup.
B) Perform a page restore.
C) Restore the latest full backup. Then, restore each differential backup taken before the time of failure from the most recent full backup.
D) Restore the latest full backup, and restore the latest differential backup. Then, restore each log backup taken before the time of failure from the most recent differential backup.
E) Perform a partial restore.
F) Restore the latest full backup, and restore the latest differential backup. Then, restore the latest log backup.
G) Restore the latest full backup. Then, restore the latest differential backup.
H) Perform a point-in-time restore.

2. --- -
You are designing a SQL Server Integration Services (SSIS) 2012 package that imports data from a Windows Azure SQL Database database into a SQL Server database.
The SSIS package has the following requirements:
Every night, a very large amount of data is imported into the staging database.
Package processing time must be minimized.
The package must run on its own dedicated server when it is deployed to
production.
Transaction log activity when data is imported must be minimized.
You need to design the package to meet the requirements.
Which destination component should you use?

A) Raw File
B) Bulk Insert
C) OLE DB
D) ODBC

3. 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) Data Conversion
B) Multicast
C) Aggregate
D) Lookup
E) Slowly Changing Dimension

4. 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) Create a SQL Server Agent job to execute the SSISDB.catalog.create_execution and SSISDB.catalog.*tart_execution stored procedures.
B) Use an event handler for OnError for the package.
C) Deploy the project by using dtutil.exe with the /COPY DTS option.
D) Enable the SSIS log provider for SQL Server for OnError in the package control flow.
E) Enable the SSIS log provider for SQL Server for OnTaskFailed in the package control flow.
F) Deploy the .ispac file by using the Integration Services Deployment Wizard.
G) Deploy the project by using dtutil.exe with the /COPY SQL option.
H) View the job history for the SQL Server Agent job.
I) Use an event handler for OnTaskFailed for the package.
J) Store the System::ExecutionInstanceGUID variable in the custom log table.
K) Create a SQL Server Agent job to execute the SSISDB.catalog.validate_package stored procedure.
L) Use an event handler for OnError for each data flow task.
M) Create a table to store error information. Create an error output on each data flow destination that writes OnError event text to the table.
N) Create a table to store error information. Create an error output on each data flow destination that writes OnTaskFailed event text to the table.
O) Store the System::ServerExecutionID variable in the custom log table.
P) Create a SQL Server Agent job to execute the SSISDB.catalog.validate_project stored procedure.
Q) View the All Messages subsection of the All Executions report for the package.
R) Store the System::SourceID variable in the custom log table.

5. 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) Create a clustered index on the Transaction table.
B) Partition the table by day and store.
C) Reduce the value of the Maximum Insert Commit Size property.
D) Run the package in Performance mode.
