You create a Web page that has an ASP.NET menu.
You need to ensure that the menu items are populated from an array of strings in your code-behind file.
What should you do?

• A. Write a JavaScript function that uses document.write to write out an asp:MenuItem for each string array element.
• B. Set the DataSource attribute of asp:Menu to the name of the array.
• C. In the Page_Render handler, use Response.Write to write out an asp:MenuItem for each string array element.
• D. In the Page_Load handler, create an instance of asp:MenuItem for each string array element, and add each of these instances to the menu's Items collection.

You are implementing an ASP.NET Web site.
The site allows users to explicitly choose the display language for the site's Web pages.
You create a Web page that contains a DropDownList named ddlLanguage, as shown in the following code
segment.
<asp:DropDownList ID="ddlLanguage" runat="server" AutoPostBack="True"
ClientIDMode="Static" OnSelectedIndexChanged="SelectedLanguageChanged"> <asp:ListItem Value="en">English</asp:ListItem> <asp:ListItem Value="es">Spanish</asp:ListItem> <asp:ListItem Value="fr">French</asp:ListItem> <asp:ListItem Value="de">German</asp:ListItem>
</asp:DropDownList>
The site contains localized resources for all page content that must be translated into the language that is
selected by the user.
You need to add code to ensure that the page displays content in the selected language if the user selects
a language in the drop-down list.
Which code segment should you use?

• A. protected void SelectedLanguageChanged(object sender, EventArgs e) {
  Page.UICulture = ddlLanguage.SelectedValue;
  }
• B. protected override void InitializeCulture() {
  Page.UICulture = Request.Form["ddlLanguage"];
  }
• C. protected override void InitializeCulture() {
  Page.Culture = ddlLanguage.SelectedValue;
  }
• D. protected void Page_Load(object sender, EventArgs e) {
  Page.Culture = Request.Form["ddlLanguage"];
  }

You have a C# code snippet with 2 classes, one composed by elements of the other. Something like
public class Student {
public string Name {get;set;} } public class Supervisor
{
public string name {get;set;}
public List<Student> {get;set;} }
And a markup code snippet, with 2 repeaters imbricated + a ObjectDataSource retrieving a list of
Supervisors, the top level repeater "rptSupervisors" is bound using ObjectDataSourceID to the
ObjectDataSource, and the inside one "rptStudents" is not bound yet.
We understand that we need a list of supervisors and sublists of their relative students.

• A. another dummy solution involving a "supervisors have all the same students" situation
• B. databinding directly the rptStudents in the page load or something dummy like that (don't remember exactly)
• C. bind rptStudents with the list of current item in SupervisorsList using the ItemCommand event of the rptSupervisor repeater
• D. bind rptStudents with the list of current item in SupervisorsList using the ItemDataBound event of the rptStudents repeater

You are implementing a method in an ASP.NET application that includes the following requirements.
Store the number of active bugs in the cache.
The value should remain in the cache when there are calls more often than every 15 seconds.
The value should be removed from the cache after 60 seconds.
You need to add code to meet the requirements. Which code segment should you add?

• A. Cache.Insert("ActiveBugs", result, null, DateTime.Now.AddSeconds(60), TimeSpan.FromSeconds(15));
• B. Cache.Insert("ActiveBugs", result, null, Cache.NoAbsoluteExpiration, TimeSpan.FromSeconds(15)); CacheDependency cd = new CacheDependency(null, new string[] { "ActiveBugs" }); Cache.Insert("Trigger", DateTime.Now, cd, DateTime.Now.AddSeconds(60), Cache.NoSlidingExpiration);
• C. Cache.Insert("Trigger", DateTime.Now, null, DateTime.Now.AddSeconds(60), Cache.NoSlidingExpiration); CacheDependency cd = new CacheDependency(null, new string[] { "Trigger" }); Cache.Insert("ActiveBugs", result, cd, Cache.NoAbsoluteExpiration, TimeSpan.FromSeconds(15));
• D. CacheDependency cd = new CacheDependency(null, new string[] { "Trigger" }); Cache.Insert("Trigger", DateTime.Now, null, DateTime.Now.AddSeconds(60), Cache.NoSlidingExpiration); Cache.Insert("ActiveBugs", result, cd, Cache.NoAbsoluteExpiration, TimeSpan.FromSeconds(15));
