You need to enable separate processing streams for a subset of rows based on the source product code.
Which Data Flow transformation should you use?

A) Data Conversion
B) Script Task
C) Destination Assistant
D) Conditional Split

2. Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
To ease the debugging of packages, you standardize the SQL Server Integration Services (SSIS) package logging methodology.
The methodology has the following requirements:
Centralized logging in SQL Server
Simple deployment
Availability of log information through reports orT-SQL
Automatic purge of older log entries
Configurable log details
-----
You need to configure a logging methodology that meets the requirements while minimizing
the amount of deployment and development effort.
What should you do?

A) use the Project Deployment Wizard.
B) create an OnError event handler.
C) Add a data tap on the output of a component in the package data flow.
D) Run the package by using the dtexecui.exe utility and the SQL Log provider.
E) Run the package by using the dtexec /rep /conn command.
F) Use the gacutil command.
G) Deploy the package by using an msi file.
H) Run the package by using the dtexec /dumperror /conn command.
