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

You are developing an ASP.NET Web application.
The application must pass an object that contains user-specific data between multiple pages.
The object is more than 100 KB in size when serialized.You need to minimize the amount of data is sent to
the user.
What should you do?

• A. Store the object instance in a session variable.
• B. Pass the object data in a hidden field.
• C. Encode the object data and pass it in a query string parameter.
• D. Use a cookie that contains the object data.

You are implementing an ASP.NET page in an e-commerce application.
Code in a btnAddToCart_Click event handler adds a product to the shopping cart.
The page should check the status of the shopping cart and always show a cart icon when one or more
items are in the shopping cart.
The page should hide the icon when the shopping cart has no items.
You need to add an event handler to implement this requirement.
Which event handler should you add?

• A. Page_PreInit
• B. Page_PreRender
• C. btnAddToCart_Click
• D. Page_Load

You are implementing an ASP.NET application that uses data-bound GridView controls in multiple pages. You add JavaScript code to periodically update specific types of data items in these GridView controls. You need to ensure that the JavaScript code can locate the HTML elements created for each row in these GridView controls, without needing to be changed if the controls are moved from one page to another. What should you do?

• A. Set the ClientIDRowSuffix attribute of each unique GridView control to a different value.
• B. Set the ClientIDMode attribute to Predictable in the web.config file.
• C. Set the @ OutputCache directive's VaryByControl attribute to the ID of the GridView control.
• D. Replace the GridView control with a ListView control.

You are developing an ASP.NET Web page. You add the following markup to the page.
<asp:FileUpload id="FileUpload1" runat="server" />
<asp:Button id="btnUpload" Text="Upload selected file"
OnClick="btnUpload_Click" runat="server" />
<asp:Label id="lblFeedback" runat="server" />
You add the following code segment to the code-behind. (Line numbers are included for reference only.)
01 protected void btnUpload_Click(object sender, EventArgs e)
02 {
03 if (...)
04 {
05 string saveName = Path.Combine(@"c:\uploadedfiles\",
FileUpload1.FileName);
06
07 lblFeedback.Text = "File successfully uploaded.";
08 }
09 else
10 {
11 lblFeedback.Text = "File upload failed.";
12 }
13 }
You need to save the uploaded file and display a message to the user that indicates that the upload either
succeeded or failed.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Insert the following code segment at line 6.
  FileUpload1.FileContent.CopyTo(new FileStream(saveName, FileMode.Open);
• B. Replace line 3 with the following code segment.
  if (FileUpload1.HasFile)
• C. Replace line 3 with the following code segment.
  if (FileUpload1.FileContent.Length > 0)
• D. Insert the following code segment at line 6.
  FileUpload1.SaveAs(saveName);
