Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to several SQL Server databases. You create a function that modifies customer records that are stored in multiple databases. All updates for a given record are performed in a single transaction. You need to ensure that all transactions can be recovered. What should you do?

A) Call the Reenlist method of the TransactionManager class.
B) Call the EnlistVolatile method of the Transaction class.
C) Call the RecoveryComplete method of the TransactionManager class.
D) Call the EnlistDurable method of the Transaction class.

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. The application uses DataContexts to query the database. You create a function that meets the following requirements: *Updates the Customer table on the database when a customer is marked as deleted. *Updates the related entries in other tables (CustomerAddress, CustomerContacts) by marking them as deleted. *Prevents consumer code from setting the Deleted column's value directly. You need to ensure that the function verifies that customers have no outstanding orders before they are marked as deleted. You also need to ensure that existing applications can use the updated function without requiring changes in the code. What should you do?

A) Override the Delete operation of the DataContext object.
B) Modify the SELECT SQL statement provided to the DataContext object to use an INNER JOIN between the Customer and Orders tables.
C) Override the Update operation of the DataContext object.
D) Add new entities to the DataContext object for the Customers and Orders tables.

3. You need to design a deployment solution for the rewritten Web application. Which approach should you recommend?

A) Use MSDeploy and FTP.
B) Use DB Deployment and One-Click Publishing.
C) Use MSDeploy and One-Click Publishing.
D) Use DB Deployment and FTP.

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database. The application uses a DataTable named
OrderDetailTable that has the following columns: "ID "OrderID "ProductID "Quantity "LineTotal Some
records contain a null value in the LineTotal field and 0 in the Quantity field. You write the following code
segment. (Line numbers are included for reference only.)
01DataColumn column = new DataColumn("UnitPrice", typeof(double));
02
03OrderDetailTable.Columns.Add(column);
You need to add a calculated DataColumn named UnitPrice to the OrderDetailTable object. You also need
to ensure that UnitPrice is set to 0 when it cannot be calculated. Which code segment should you insert at
line 02?

A) column.Expression = "LineTotal/Quantity";
B) column.Expression = "if(Quantity > 0, LineTotal/Quantity, 0)";
C) column.Expression = "iif(Quantity > 0, LineTotal/Quantity, 0)";
D) column.Expression = "LineTotal/ISNULL(Quantity, 1)";

5. You are designing a user input form that is part of an ASP.NET Web Forms application. You need to ensure that users cannot attack the Web server by submitting invalid data. Which approach should you recommend?

A) Write an OnClick method for the Submit button that rejects form submissions that contain invalid data.
B) Write an onSubmit JavaScript handler that validates all form input.
C) Write an onSubmit JavaScript handler that URL-encodes all data that is passed to the server.
D) Install a certificate on the Web server, and force all Web traffic to use SSL.
