You need to design a solution for programmatically adding reusable user-interface code to views and allowing the user-interface code to be rendered from the server side. Which approach should you recommend

• A. Create an HtmlHelper extension method.
• B. Create a controller that returns an ActionResult.
• C. Create a jQuery library plug-in.
• D. Create a WebForm server control that stores values in ViewState.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to manage customer and related order records. You add a new order for an existing customer. You need to associate the Order entity with the Customer entity. What should you do?

• A. Use the Attach method of the ObjectContext to add both Order and Customer entities.
• B. Use the AddObject method of the ObjectContext to add both Order and Customer entities.
• C. Call the Add method on the EntityCollection of the Order entity.
• D. Set the Value property of the EntityReference of the Order entity.

You use Microsoft Visual Studio 2010 and Microsoft ADO.NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. You use the ADO.NET LINQ to SQL model to retrieve data from the database. You use stored procedures to return multiple result sets. You need to ensure that the result sets are returned as strongly typed values. What should you do?

• A. Apply the FunctionAttribute and ParameterAttribute to the stored procedure function and directly access the strongly typed object from the results collection.
• B. Apply the ParameterAttribute to the stored procedure function. Use the GetResult <TElement> method to obtain an enumerator of the correct type.
• C. Apply the FunctionAttribute and ResultTypeAttribute to the stored procedure function. Use the GetResult <TElement> method to obtain an enumerator of the correct type.
• D. Apply the ResultTypeAttribute to the stored procedure function and directly access the strongly typed object from the results collection.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database. You write the following code segment that
executes two commands against the database within a transaction. (Line numbers are included for
reference only.)
01using (SqlConnection connection = new SqlConnection(cnnStr)) {
02connection.Open();
03SqlTransaction sqlTran = connection.BeginTransaction();
04SqlCommand command = connection.CreateCommand();
05command.Transaction = sqlTran;
06try {
07command.CommandText = "INSERT INTO Production.ScrapReason(Name) VALUES('Wrong size')";
08command.ExecuteNonQuery();
09command.CommandText = "INSERT INTO Production.ScrapReason(Name) VALUES('Wrong color')";
10command.ExecuteNonQuery();
11
12}
You need to log error information if the transaction fails to commit or roll back.
Which code segment should you insert at line 11?

• A. sqlTran.Commit(); } catch (Exception ex) { sqlTran.Rollback(); Trace.WriteLine(ex.Message); }
• B. sqlTran.Commit(); } catch (Exception ex) { Trace.WriteLine(ex.Message); try { sqlTran.Rollback(); } catch (Exception exRollback) { Trace.WriteLine(exRollback.Message); } } }
• C. catch (Exception ex) { sqlTran.Rollback(); Trace.WriteLine(ex.Message); } finaly { try { sqltran.commit( ); } catch (Exception exRollback) { Trace.WriteLine(excommit.Message); }}
• D. catch (Exception ex){ Trace.WriteLine(ex.Message); try{ sqlTran.Rollback(); } catch (Exception exRollback){ Trace.WriteLine(exRollback.Message); }} finaly { sqltran.commit( );}}
