You create a Web page that contains drop-down menus that are defined by using div tags in the following
code.
<div class="dropdown-menu">
<div class="menu-title">Menu One</div>
<div class="menu-items" style="display:none;">
<div><a href="#">Item One</a></div>
<div><a href="#">Item Two</a></div>
</div>
</div>
<div class="dropdown-menu">
<div class="menu-title">Menu Two</div>
<div class="menu-items" style="display:none;">
<div><a href="#">Item Three</a></div>
<div><a href="#">Item Four</a></div>
</div>
</div>
You need to write a JavaScript function that will enable the drop-down menus to activate when the user
positions the mouse over the menu title.
Which code segment should you use?

• A.$(".dropdown-menu").hover( function () { $(".menu-items").slideDown(100); }, function () { $(".menu-items").slideUp(100); } );
• B.$(".dropdown-menu").hover(
  function () {
  $("this,".menu-title",).slideDown(100);
  },
  function () {
  $("this.menu-title",).slideUp(100);
  }
  );
• C.$(".dropdown-menu").hover( function () { $(".menu-items", this).slideDown(100); }, function () { $(".menu-items",this).slideUp(100); } );
• D.$(".dropdown-menu").hover( function () { $(this)".slideDown(100); }, function () { $(this).slideUp(100); } );

You are designing the user interface for an ASP.NET Web application. The Web application allows several departments to personalize the style of their sections of the Web application.
All departmental section styles derive from the core styles of the Web application and can only append to
the Web application's core styles. The departmental master pages inherit from the Web application's
master page.
You need to ensure that core CSS styles appear in all pages of the Web application.
Which approach should you recommend?

• A.Link from the Web application's master page to a css.ascx file containing the CSS styles.
• B.Add a ContentPlaceHolder containing the CSS styles to the Web application's master page.
• C.Link from the Web application's master page to a .css file containing the CSS styles.
• D.Add a master.css file containing the CSS styles to the Web application.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. You create classes by using LINQ to SQL based on the records shown in the exhibit. (Click the Exhibit button.) You need to create a LINQ query to retrieve a list of objects that contains the OrderID and CustomerID properties. You need to retrieve the total price amount of each Order record. What are two possible ways to achieve this goal (Each correct answer presents a complete solution. Choose two.)

• A.from order in dataContext.Orders group order by order.OrderID into g join details in dataContext.Order_Details on g.Key equals details. OrderID select new { OrderID = details.OrderID, CustomerID = details.Order.CustomerID, TotalAmount = details.UnitPrice * details.Quantity }
• B.dataContext.Orders.GroupJoin(dataContext.Order_Details, o => o.OrderID, d => d.OrderID, (ord, dts) => new { OrderID = ord.OrderID, CustomerID = ord.CustomerID, TotalAmount = dts.Sum(od => od. UnitPrice * od.Quantity) } )
• C.from details in dataContext.Order_Details group details by details.OrderID into g join order in dataContext.Orders on g.Key equals order.OrderID select new { OrderID = order.OrderID, CustomerID = order.CustomerID, TotalAmount = g.Sum(od => od.UnitPrice * od.Quantity) }
• D.dataContext.Order_Details.GroupJoin(dataContext.Orders, d => d.OrderID, o => o.OrderID, (dts, ord) => new { OrderID = dts.OrderID, CustomerID = dts.Order.CustomerID, TotalAmount = dts.UnitPrice * dts.Quantity } )

You are creating a Windows Communication Foundation (WCF) service. You do not want to expose the internal implementation at the service layer. You need to expose the following class as a service named Arithmetic with an operation named Sum. public class Calculator {
public int Add(int x, int y)
{
}
}
Which code segment should you use?

• A.[ServiceContract(Name="Arithmetic")] public class Calculator {
  [OperationContract(Name="Sum")]
  public int Add(int x, int y)
  {
  ...
  }
  }
• B.[ServiceContract(ConfigurationName="Arithmetic")] public class Calculator {
  [OperationContract(Action="Sum")]
  public int Add(int x, int y)
  {
  ...
  }
  }
• C.[ServiceContract(Namespace="Arithmetic")] public class Calculator {
  [OperationContract(Action="Sum")]
  public int Add(int x, int y)
  {
  ...
  }
  }
• D.[ServiceContract(Name="Arithmetic")] public class Calculator {
  [OperationContract(ReplyAction="Sum")]
  public int Add(int x, int y)
  {
  ...
  }
  }

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database. The application has two DataTable objects that
reference the Customers and Orders tables in the database. The application contains the following code
segment. (Line numbers are included for reference only.
01DataSet customerOrders = new DataSet();
02customerOrders.EnforceConstraints = true;
03ForeignKeyConstraint ordersFK = new ForeignKeyConstraint("ordersFK",
04customerOrders.Tables["Customers"].Columns["CustomerID"],
05customerOrders.Tables["Orders"].Columns["CustomerID"]);
06
07customerOrders.Tables["Orders"].Constraints.Add(ordersFK);
You need to ensure that an exception is thrown when you attempt to delete Customer records that have
related Order records. Which code segment should you insert at line 06?

• A.ordersFK.DeleteRule = Rule.Cascade;
• B.ordersFK.DeleteRule = Rule.SetNull;
• C.ordersFK.DeleteRule = Rule.SetDefault;
• D.ordersFK.DeleteRule = Rule.None;
