Microsoft 70-515 : TS: Web Applications Development with Microsoft .NET Framework 4

You are implementing an ASP.NET MVC 2 Web application.
The URL with path /Home/Details/{country} will return a page that provides information about the named
country.
You need to ensure that requests for this URL that contain an unrecognized country value will not be
processed by the Details action of HomeController.
What should you do?

• A. Add the ValidateAntiForgeryToken attribute to the Details action method.
• B. Create a class that implements the IRouteHandler interface. Configure the default route to use this class.
• C. Add the Bind attribute to the country parameter of the Details action method. Set the attribute's Prefix property to Country.
• D. Create a class that implements the IRouteConstraint interface. Configure the default route to use this class.

You are implementing an ASP.NET Web site.
The Web site contains a Web service named CustomerService.
The code-behind file for the CustomerService class contains the following code segment.
public class ProductService : System.Web.Services.WebService
{ public List<Product> GetProducts(int categoryID) {
return GetProductsFromDatabase(categoryID); } }
You need to ensure that the GetProducts method can be called by using AJAX.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Apply the WebMethod attribute to the GetProducts method.
• B. Apply the ScriptMethod attribute to the GetProducts method.
• C. Apply the ScriptService attribute to the ProductService class.
• D. Apply the WebService attribute to the ProductService class.

You are developing a Web page.
The user types a credit card number into an input control named cc and clicks a button named submit.
The submit button sends the credit card number to the server.
A JavaScript library includes a CheckCreditCard function that returns a value of true if the credit card
appears to be valid, based on its checksum.
You need to ensure that the form cannot be used to submit invalid credit card numbers to the server.
What should you do?

• A. On the form, add an onSubmit handler that calls CheckCreditCard and cancels the form submission if the input is invalid.
• B. Configure the input control and the submit button to run on the server. Add a submit_OnClick handler that calls CheckCreditCard and rejects the form submission if the input is invalid.
• C. On the input control, add an onChange handler that calls CheckCreditCard and cancels the form submission when the input is invalid.
• D. Configure the input control to run on the server. On the submit button, add a server-side OnClick handler that calls CheckCreditCard and rejects the form submission if the input is invalid.

A Web page includes the HTML shown in the following code segment.
<span id="ref">
<a name=Reference>Check out</a> the FAQ on <a href="http:// www.contoso.com">Contoso</a>'s web site for more information: <a href="http:// www.contoso.com/faq">FAQ</a>. </span> <a href="http://www.contoso.com/home">Home</a>
You need to write a JavaScript function that will dynamically format in boldface all of the hyperlinks in the ref
span.
Which code segment should you use?

• A. $("ref").filter("a").css("bold");
• B. $("a").css({fontWeight:"bold"});
• C. $("#ref a[href]").css({fontWeight:"bold"});
• D. $("#ref").filter("a[href]").bold();

You are developing an ASP.NET Web page.
The page uses the MicrosoftAjax.js script file and the MicrosoftAjaxWebForms.js script file.
You need to ensure that both scripts are combined into a single script.
Which markup should you use?

• A. <asp:ScriptManager ID="sm1" runat="server"> <CompositeScript ScriptMode="Auto">
  <Scripts>
  <asp:ScriptReference Name="MicrosoftAjax.js" />
  <asp:ScriptReference Name="MicrosoftAjaxWebForms.js" />
  </Scripts>
  </CompositeScript>
  </asp:ScriptManager>
• B. <asp:ScriptManager ID="sm1" runat="server"> <CompositeScript>
  <Scripts>
  <asp:ScriptReference Name="MicrosoftAjax.js" />
  <asp:ScriptReference Name="MicrosoftAjaxWebForms.js" />
  </Scripts>
  </CompositeScript>
  </asp:ScriptManager>
• C. <asp:ScriptManager ID="sm1" runat="server">
  <Scripts>
  <asp:ScriptReference Name="MicrosoftAjax.js" />
  <asp:ScriptReference Name="MicrosoftAjaxWebForms.js" />
  </Scripts>
  </asp:ScriptManager>
• D. <asp:ScriptManager ID="sm1" runat="server"> <CompositeScript ScriptMode="Release">
  <Scripts>
  <asp:ScriptReference Name="MicrosoftAjax.js" />
  <asp:ScriptReference Name="MicrosoftAjaxWebForms.js" />
  </Scripts>
  </CompositeScript>
  </asp:ScriptManager>
