Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You are writing a SQL Server Integration Services (SSIS) package that transfers data from a legacy system.
Data integrity in the legacy system is very poor. Invalid rows are discarded by the package but must be logged to a CSV file for auditing purposes.
You need to establish the best technique to log these invalid rows while minimizing the amount of development effort.
What should you do?

A) Run the package by using the dtexec /rep /conn command.
B) Run the package by using the dtexec /dumperror /conn command.
C) Deploy the package by using an msi file.
D) Add a data tap on the output of a component in the package data flow.
E) Run the package by using the dtexecui.exe utility and the SQL Log provider.
F) Create a reusable custom logging component.
G) Use the gacutil command.
H) Use the dtutil /copy command.
I) Use the Project Deployment Wizard.
J) Create an OnError event handler.
K) Deploy the package to the Integration Services catalog by using dtutfl and use SQL Server to store the configuration.

2. You administer a Microsoft SQL Server 2012 server. You plan to deploy new features to an application.
You need to evaluate existing and potential clustered and non-clustered indexes that will improve performance.
What should you do?

A) Use the Database Engine Tuning Advisor.
B) Query the sys.dm_db_index_usage_stats DMV.
C) Query the sys.dm_db_missing_index_columns DMV.
D) Query the sys.dm_db_missing_index_details DMV.

3. --- -
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) Bulk Insert
B) Raw File

4. HOTSPOT
You are developing a SQL Server Integration Service (SSIS) package. The package loads a customer dimension table by using a data flow task.
Changes to the customer attributes must be tracked over time.
You need to produce a checksum value to identify the rows that have changed since the last Extract, Transform and Load (ETL) process execution. You need to use the least amount of development effort to achieve this goal.
Which transformation should you use? (To answer, select the appropriate transformation in the answer area.)

5. 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) Create one SSIS catalog Environment. Change the values of each Environment variable at package execution time.
B) 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.
C) For each target server, create a separate XML configuration file. Select the XML configuration file at package execution time.
D) For each target server, create separate registry entry configurations. Select the registry entry at package execution time.
