You are implementing an ASP.NET AJAX page that contains two div elements.
You need to ensure that the content of each div element can be refreshed individually, without requiring a
page refresh.
What should you do?

• A. Add a form and two update panels to the page. Add a script manager to the form. Add a content template to each update panel, and move a div element into each content template.
• B. Add two forms to the page. Add a script manager and an update panel to each form. Add a content template to each update panel, and move each div element into a content template.
• C. Add a form and two update panels to the page. Add two script managers to the form, one for each update panel. Add a content template to each update panel, and move each div element into a content template.
• D. Add two forms to the page. Add a script manager and an update panel to each form. Add a content template to each update panel, and move each div element into a content template.

You are developing an ASP.Net web application.
The application includes a master page named CustomerMaster.master that contains a public string
property name EmployeeName application also includes a second master page named
NestedMaster.master that is defined by the following directive.
<%@ Master Language="C#"
MasterPageFile="~/CustomMaster.Master"
CodeBehind="NestedMaster.Master.cs"
Inherits="MyApp.NestedMaster"%>
You add a content page that uses the NestedMaster.master page file.The content page contains a label
control named lblEmployeeName.
You need to acces the EmployeeName value and display the value within the lblEmployeeName label.
What should you do?

• A. Add the following directive to the content page. <%@ MasterTypeVirtualPAth="~/CustomMaster.master" %>
  Add the following code segment to the code-behind file of the content page.
  public void Page_load(object s, EventArgs e)
  {
  lblEmployeeName.text=this.Master.EmployeeName;
  }
• B. Add the following code segment to the code-behind file of the content page. public void Page_load(object s, EventArgs e) { lblEmployeeName.text=
  ((MyApp.CustomMaster)Page.Master.Parent).EmployeeName;
  }
• C. Add the following code segment to the code-behind file of the content page.
  public void Page_load(object s, EventArgs e)
  {
  lblEmployeeName.text=
  ((MyApp.CustomerMaster)Page.Master.Master)
  .FindControl("EmployeeName").toString();
  }
• D. Add the following code segment to the code-behind file of the content page.
  public void Page_load(object s, EventArgs e)
  {
  lblEmployeeName.text=
  ((MyApp.CustomerMaster)Page.Master.Master).EmployeeName;
  }

You are developing an ASP.NET web application.
The application will contain a page that is customized for various browsers. The application will use output
caching to optimize performance.
You need to ensure that the page is cached by browser type and major version only.
Which attribute should you add to the OutputCache directive?

• A. VaryByCustom="browser"
• B. VaryByHeader="browser"
• C. VaryByHeader="User-Agent"
• D. VaryByCustom="User-Agent"

You are implementing an ASP.NET application that includes the following requirements.
Retrieve the number of active bugs from the cache, if the number is present.
If the number is not found in the cache, call a method named GetActiveBugs, and save the result under the
ActiveBugs cache key.
Ensure that cached data expires after 30 seconds.
You need to add code to fulfill the requirements.
Which code segment should you add?

• A. int numOfActiveBugs = (int?)Cache["ActiveBugs"];
  if (!numOfActiveBugs.HasValue)
  {
  int result = GetActiveBugs();
  Cache.Insert("ActiveBugs", result, null,
  Cache.NoAbsoluteExpiration, TimeSpan.FromSeconds(30));
  numOfActiveBugs = result;
  }
  ActiveBugs = numOfActiveBugs.Value;
• B. int? numOfActiveBugs = (int?)Cache["ActiveBugs"];
  if (!numOfActiveBugs.HasValue)
  {
  int result = GetActiveBugs();
  Cache.Insert("ActiveBugs", result, null,
  DateTime.Now.AddSeconds(30), Cache.NoSlidingExpiration);
  numOfActiveBugs = result;
  }
  ActiveBugs = numOfActiveBugs.Value;
• C. int numOfActiveBugs = (int) Cache.Get("ActiveBugs");
  if (numOfActiveBugs != 0)
  {
  int result = GetActiveBugs();
  Cache.Insert("ActiveBugs", result, null,
  DateTime.Now.AddSeconds(30), Cache.NoSlidingExpiration);
  numOfActiveBugs = result;
  }
  ActiveBugs = numOfActiveBugs;
• D. int numOfActiveBugs = 0;
  if (Cache["ActiveBugs"] == null)
  { int result = GetActiveBugs(); Cache.Add("ActiveBugs", result, null, DateTime.Now.AddSeconds(30), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); numOfActiveBugs = result;
  }
  ActiveBugs = numOfActiveBugs;

You create a Web page that contains the following code.
<script type="text/javascript">
var lastId = 0; </script> <div class="File">
Choose a file to upload:
<input id="File0" name="File0" type="file" /> </div> <input id="AddFile" type="button" value="Add a File" /> <input id="Submit" type="submit" value="Upload" />
You need to provide the following implementation.
Each time the AddFile button is clicked, a new div element is created.
The new div element is appended after the other file upload div elements and before the AddFile span.
Each new element has a unique identifier.
Which code segment should you use?

• A. $("#AddFile").click(function () { var id = "File" + ++lastId; $(".File:first").clone(true).attr({ id: id, name: id }).insertBefore
  ("#AddFile");
  });
• B. $("#AddFile").click(function () { var id = "File" + ++lastId; var item = $(".File:first").clone(true); $("input:file", item).attr({ id: id, name: id }); item.insertBefore("#AddFile");
  });
• C. $("#AddFile").click(function () {
  var id = "File" + ++lastId;
  });
• D. $("#AddFile").click(function () { var id = "File" + ++lastId; var item = $(".File:first").clone(true); $("input:file", item).attr({ id: id, name: id }); item.insertAfter("input[type=file]");
  });
