Microsoft TS: Accessing Data with Microsoft .NET Framework 4 Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft.NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database. You use the ADO.NET LINQ to Entity model
to retrieve data from the database.
You need to call a function that is defined in the conceptual model from within the LINQ to Entities queries.
You create a common language runtime (CLR) method that maps to the function. What should you do
next?

A) Apply the EdmFunctionAttribute attribute to the method.
B) Declare the method as static.
C) Declare the method as abstract.
D) Apply the EdmComplexTypeAttribute attribute to the method.

2. You use Microsoft .NET Framework 4.0 and the Entity Framework to develop an application.
You create an Entity Data Model that has an entity named Customer. You set the optimistic concurrency
option for Customer.
You load and modify an instance of Customer named loadedCustomer, which is attached to an
ObjectContext named context.
You need to ensure that if a concurrency conflict occurs during a save, the application will load up-to-date
values from
the database while preserving local changes. Which code segment should you use?

A) try {
context.SaveChanges();
}
catch(EntitySqlException ex)
{
context.Refresh(RefreshMode.ClientWins, loadedCustomer);
}
B) try {
context.SaveChanges();
}
catch(OptimisticConcurrencyException ex)
{
context.Refresh(RefreshMode.ClientWins, loadedCustomer);
}
C) try {
context.SaveChanges();
}
catch(EntitySqlException ex)
{
context.Refresh(RefreshMode.StoreWins, loadedCustomer);
}
D) try {
context.SaveChanges();
}
catch(OptimisticConcurrencyException ex)
{
context.Refresh(RefreshMode.StoreWins, loadedCustomer);
}

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.

<Condition ColumnName="ProductType" IsNull="false" />
Insert the following code at line EX250:
<Condition ColumnName="PartType" IsNull="true" />
