The application will not modify retrieved data. You need to ensure that all the requested data is retrieved.
You want to achieve this goal using the minimum amount of resources. What should you do?

A) Set DeferredLoadingEnabled to true on the DataContext class.
B) Set DeferredLoadingEnabled to false on the DataContext class.
C) Set ObjectTrackingEnabled to true on the DataContext class.
D) Set ObjectTrackingEnabled to false on the DataContext class.

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the Entity Framework Designer to create an Entity Data Model using model-first development.
The database has the following requirements:
-each table must have a datetime column named time_modified
-each table requires a trigger that updates the value of the time_modified column when a row is inserted or updated
You need to ensure that the database script that is created by using the Generate Database From Model
option meets the requirements.
What should you do?
