You are implementing an ASP.NET AJAX page.
You add two UpdatePanel controls named pnlA and pnlB. pnlA contains an UpdatePanel control named
pnlAInner in its content template.
You have the following requirements.
Update panels pnlA and pnlB must refresh their content only when controls that they contain cause a postback.
Update panel pnlAInner must refresh its content when controls in either pnlA or pnlB or pnlAInner cause
a postback.
You need to configure the panels to meet the requirements. What should you do?

• A. Set the UpdateMode of pnlA and pnlB to Conditional. Set the UpdateMode of pnlAInner to Always.
• B. Set the UpdateMode of pnlA and pnlB to Always. Set the UpdateMode of pnlAInner to Always, and add AsyncPostBackTrigger elements to its Triggers element for every control in pnlB.
• C. Set the UpdateMode of pnlA and pnlB to Conditional. Set the UpdateMode of pnlAInner to Conditional, and add AsyncPostBackTrigger elements to its Triggers element for every control in pnlA.
• D. Set the UpdateMode of pnlA and pnlB to Always. Set the UpdateMode of pnlAInner to Conditional.

You are updating an ASP.NET Web Application. The application includes the fallowing classes.
public class Supervisor
{ public string FirstName { get; set; } public string LastName { get; set; } public List<Employee> Employees { get; set; }
}
public class Employee
{ public String FirstName { get; set; } public String LastName { get; set; }
}
An application page contains the fallowing markup.
<asp:Repeater ID="rptSupervisor" runat="server" DataSourceID="odsEmployees"> <ItemTemplate> <%#Eval("FirstName") %> <%#Eval("LastName") %><br /> Employees:<br />
<asp:Repeater ID="rptEmployees" runat="server">
<ItemTemplate>
<%#Eval("FirstName") %> <%#Eval("LastName") %>
<br />
</ItemTemplate>
</asp:Repeater>
</ItemTemplate> </asp:Repeater> <asp:ObjectDataSource ID="odsEmployees" runat="server" SelectMethod="GetSupervisorWithEmployees"
TypeName="BusinessLayer"> </asp:ObjectDataSource>
You need to ensure that the page displays a list of supervisors with their corresponding employees.
What should you do?

• A. Bind rptEmployees during the OnItemDataBound event of rptEmployees.
• B. Set the rptEmployees DataSourceID attribute to "Employees".
• C. Set the rptEmployees DataSource attribute to <%# Eval("Employees") %>
• D. Bind rptEmployees during the OnItemCommand event of rptSupervisor.

You are implementing an ASP.NET MVC 2 Web application that contains the following class.
public class DepartmentController : Controller { static List<Department> departments = new List<Department>();
public ActionResult Index()
{
return View(departments);
}
public ActionResult Details(int id)
{
return View(departments.Find(x => x.ID==id));
}
public ActionResult ListEmployees(Department d)
{
List<Employee> employees = GetEmployees(d);
return View(employees);
} }
You create a strongly typed view that displays details for a Department instance.
You want the view to also include a listing of department employees.
You need to write a code segment that will call the ListEmployees action method and output the results in
place.
Which code segment should you use?

• A. <% Html.RenderPartial("ListEmployees", Model); %>
• B. <%= Html.Action("ListEmployees", Model) %>
• C. <%= Html.ActionLink("ListEmployees", "Department", "DepartmentController") % >
• D. <%= Html.DisplayForModel("ListEmployees") %>

You are developing an ASP.NET web application that you will deploy to an Internet Information Services
(IIS) 7.0 server.
The application will run in Integrated pipeline mode. The application contains a phot gallery of images that
are stored in a Microsoft SQL Server database.
You need to ensure that the application can retrieve images from the database without blocking IIS worker
process threads.
What should you do?

• A. Create an asynchronous HttpHandler that is registered in the <handlers> section under system.webServer in the web.config file.
• B. Create a synchronous HttpHandler that is registered in the <httpHandlers> section in the web.config file.
• C. Create a custom HttpModule that is registered in the <httpModules> section in the web.config file.
• D. Create an asynchronous HttpHandler that is registered in the <httpHandlers> section in the web.config file.
