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 and contains a LINQ to SQL data model.
The data model contains a function named createCustomer that calls a stored procedure.
The stored procedure is also named createCustomer. The createCustomer function has the following
signature.
createCustomer (Guid customerID, String customerName, String address1)
The application contains the following code segment. (Line numbers are included for reference only.)
01 CustomDataContext context = new CustomDataContext(); 02 Guid userID = Guid.NewGuid();
03 String address1 = "1 Main Steet";
04 String name = "Marc";
05 ...
You need to use the createCustomer stored procedure to add a customer to the database. Which code segment should you insert at line 05?

A) context.ExecuteCommand("createCustomer", userID, customer1, address1); Customer customer = new Customer() { ID = userID, Address1 = address1, Name = customer1, };
B) context.ExecuteQuery(typeof(Customer), "createCustomer", customer);
C) context.ExecuteCommand("createCustomer", customer); Customer customer = new Customer() { ID = userID, Address1 = address1, Name = customer1, };
D) context.createCustomer(userID, customer1, address1);

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

database.
You need to enable query plan caching. Which object should you use?

A) EntityTransaction
B) EntityConnection
C) EntityDataReader
D) EntityCommand

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application.
You use the ADO.NET Entity Framework Designer to model entities. The application includes two
ObjectContext instances named context1 and context2.
You need to persist the changes in both object contexts within a single transaction. Which code segment
should you use?

A) using (TransactionScope scope = new TransactionScope()) { using (TransactionScope scope1 = new TransactionScope (TransactionScopeOption.RequireNew)) {
context1.SaveChanges();
}
using (TransactionScope scope2 = new TransactionScope
(TransactionScopeOption.RequireNew))
{
context2.SaveChanges();
}
}
B) using (TransactionScope scope = new TransactionScope())
{
context1.SaveChanges();
context2.SaveChanges();
}
C) using (TransactionScope scope = new TransactionScope())
{
context1.SaveChanges();
context2.SaveChanges();
scope.Complete();
}
D) using (TransactionScope scope = new TransactionScope()) { using (TransactionScope scope1 = new TransactionScope (TransactionScopeOption.RequireNew))
{
context1.SaveChanges();
scope1.Complete();
}
using (TransactionScope scope2 = new TransactionScope
(TransactionScopeOption.RequireNew))
{
context2.SaveChanges();
scope2.Complete();
}
scope.Complete();
}

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

B) Call the RecoveryComplete method of the TransactionManager class.
C) Call the EnlistVolatile method of the Transaction class.
