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

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

You create a Web page that contains the following div.
<div id="target">
</div>
You have a JavaScript array named imageurls that contains a list of image URLs.
You need to write a JavaScript function that will insert images from the URLs into target.
Which code segment should you use?

• A. $.each(imageurls, function(i,url){
  $("#target").append("<img/>").src = url;
  });
• B. $(imageurls).each(function(i,url){
  $("<img/>", url).append("#target");
  });
• C. $(imageurls).each(function(i,url){
  $("#target") += $("<img/>").attr("src", url);
  });
• D. $.each(imageurls, function(i,url){
  $("<img/>").attr("src", url).appendTo("#target");
  });

You create a page in an ASP.NET Web application.
The page retrieves and displays data from a Microsoft SQL Server database.
You need to create a data source that can connect to the database.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

• A. Use a LinqDataSource control with entity classes that represent the elements in the database.
• B. Use an XmlDataSource control together with an Xml control that represents the database.
• C. Use a SqlDataSource control and configure its ConnectionString in the web.config file.
• D. Use an ObjectDataSource control and set its TypeName property to System.Data.SqlClient.SqlConnection.

You are implementing an ASP.NET Web site.
The site uses a component that must be dynamically configured before it can be used within site pages.
You create a static method named SiteHelper.Configure that configures the component.
You need to add a code segment to the Global.asax file that invokes the SiteHelper.Configure method the
first time, and only the first time, that any page in the site is requested.
Which code segment should you use?

• A. void Application_BeginRequest(object sender, EventArgs e) {
  SiteHelper.Configure();
  }
• B. void Application_Start(object sender, EventArgs e) {
  SiteHelper.Configure();
  }
• C. Object lockObject = new Object();
  void Application_BeginRequest(object sender, EventArgs e)
  {
  lock(lockObject())
  {
  SiteHelper.Configure();
  }
  }
• D. void Application_Init(object sender, EventArgs e) {
  SiteHelper.Configure();
  }

You are implementing an ASP.NET Web application.
Users will authenticate to the application with an ID.
The application will allow new users to register for an account.
The application will generate an ID for the user based on the user's full name.
You need to implement this registration functionality.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Configure the SqlProfileProvider in the web.config file. (New answer from TestKiller, SqlMembershipProvider is not changed)
• B. Create an ASP.NET page that contains a custom form that collects the user information and then uses the Membership.CreateUser method to create a new user account.
• C. Create an ASP.NET page that contains a default CreateUserWizard control to create a new user account.
• D. Configure the SqlMembershipProvider in the web.config file.
