You use Microsoft Visual Studio 2010, Microsoft Sync Framework, and Microsoft .NET Framework 4 to create an application. You have a ServerSyncProvider connected to a Microsoft SQL Server database. The database is hosted on a Web server. Users will use the Internet to access the Customer database through
the ServerSyncProvider. You write the following code segment. (Line numbers are included for reference
only.)
01SyncTable customerSyncTable = new SyncTable("Customer");
02customerSyncTable.CreationOption = TableCreationOption. UploadExistingOrCreateNewTable;
03
04customerSyncTable.SyncGroup = customerSyncGroup;
05 this.Configuration.SyncTables.Add(customerSyncTable);
You need to ensure that the application meets the following requirements: "Users can modify data locally
and receive changes from the server. "Only changed rows are transferred during synchronization. Which
code segment should you insert at line 03?

• A.customerSyncTable.SyncDirection = SyncDirection.Snapshot;
• B.customerSyncTable.SyncDirection = SyncDirection.Bidirectional;
• C.customerSyncTable.SyncDirection = SyncDirection.UploadOnly;
• D.customerSyncTable.SyncDirection = SyncDirection.DownloadOnly;

You are implementing an ASP.NET Dynamic Data Web site.
The Web site includes a data context that enables automatic scaffolding for all tables in the data model.
The Global.asax.cs file contains the following code segment. public static void RegisterRoutes
(RouteCollection routes) { {
routes.Add(new DynamicDataRoute("{table}/ListDetails.aspx") {
Action = PageAction.List,
ViewName = "ListDetails",
Model = DefaultModel
});
routes.Add(new DynamicDataRoute("{table}/ListDetails.aspx") {
Action = PageAction.Details,
ViewName = "ListDetails",
Model = DefaultModel
});
}
You need to display the items in a table named Products by using a custom layout.
What should you do?

• A.Add a new Web page named Products.aspx to the Dynamic Data\PageTemplates folder of the Web site.
• B.Add a new Web user control named Products.ascx to the Dynamic Data\Filters folder of the Web site.
  In the code-behind file for the control, change the base class from UserControl to System.Web.
  DynamicData.QueryableFilterUserControl.
• C.Add a new Web user control named Products_ListDetails.ascx to the Dynamic Data\EntityTemplates folder of the Web site. In the code-behind file for the control, change the base class from UserControl to System.Web. DynamicData.EntityTemplateUserControl.
• D.Add a new folder named Products to the Dynamic Data\CustomPages folder of the Web site. Add a new Web page named ListDetails.aspx to the Products folder.

You are developing an ASP.NET application by using Visual Studio 2010. You need to interactively debug the entire application. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A.Define the DEBUG constant in the project settings.
• B.Select the ASP.NET debugger option in the project properties.
• C.Add a DebuggerDisplay attribute to the code-behind file of the page that you want to debug.
• D.Set the Debug attribute of the compilation node of the web.config file to true.

You are designing an ASP.NET Web Forms application that uses a database containing user names and
hashed passwords for authentication. The Web application includes a login form in which users type their
user names and passwords.
You need to design a strategy to ensure that the user's login credentials cannot be stolen through a man-
in-the-middle attack.
Which approach should you recommend?

• A.Install a certificate on the Web server, and force the login form to use SSL.
• B.Write an onSubmit JavaScript handler that URL-encodes the password before the password is passed to the server.
• C.Write an onSubmit JavaScript handler that hashes the password before the password is submitted to the server.
• D.Write an OnClick method for the Submit button that hashes the password before the password is compared with the password value that is stored in the database.

You are creating a Windows Communication Foundation (WCF) service to process orders.
The data contract for the order is defined as follows.
[DataContract]
public class Order {
[DataMember] public string CardHolderName { get; set; [DataMember]
public string CreditCardNumber { get; set; }
}
You have the following requirements:
"Enable the transmission of the contents of Order from the clients to the service.
"Ensure that the contents of CreditCardNumber are not sent across the network in clear text.
"Ensure that the contents of CreditCardNumber are accessible by the service to process the order.
You need to implement the service to meet these requirements.
What should you do?

• A.Implement the CreditCardNumber property getter and setter. In the setter, run the value of the CreditCardNumber through the MD5CryptoServiceProvider class TransformBlock method.
• B.Add a DataProtectionPermission attribute to the CreditCardNumber property and set the ProtectData property to true.
• C.Change the data type of CreditCardNumber from string to SecureString.
• D.Convert the DataContract to a MessageContract and set the ProtectionLevel property to SignAndEncrypt.
