Which two actions should you perform?
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. The service connects to a Microsoft SQL Server 2008 database. The service is hosted by an Internet Information Services (IIS) 6.0 server. You need to ensure that applications authenticate against user information stored in the database before the application is allowed to use the service. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
What should you do?
Your Windows Communication Foundation (WCF) client application uses HTTP to communicate with the service. You need to enable message logging and include all security information such as tokens and nonces in logged messages. What should you do?
Which IsolationLevel should you use?
You use Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server 2008 database.
You need to prevent dirty or phantom reads. Which IsolationLevel should you use?
Which two actions should you perform?
You create a custom server control named Task that contains the following code segment. (Line numbers are included for reference only.)
01 namespace DevControls
02 {
03 public class Task : WebControl
04 {
05 [DefaultValue(“”)]
06 public string Title { … }
07
08 protected override void RenderContents(HtmlTextWriter output)
09 {
10 output.Write(Title);
11 }
12 }
13 }
You need to ensure that adding a Task control from the Toolbox creates markup in the following format.
<Dev:Task ID=”Task1″ runat=”server” Title=”New Task” />

What should you do?
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You use Microsoft ADO.NET Entity Data Model (EDM) to model entities. You create an entity named Person with a schema defined by the following XML fragment.
<EntityType Name=”CPerson”>
<Key>
<PropertyRef Name=”PersonId” />
</Key>
<Property Name=”PersonId” Type=”Int32″ Nullable=”false” />
<Property Name=”CompanyName” Type=”String” />
<Property Name=”ContactName” Type=”String” />
<Property Name=”ContactTitle” Type=”String” />
<Property Name=”Address” Type=”String” />
</EntityType>
You need to ensure that entities within the application are able to add properties related to the city, region, and country of Person’s address. What should you do?
What are two possible ways to achieve this goal?
A WCF service code is implemented as follows. (Line numbers are included for reference only.)
01 <ServiceContract()>
02 <ServiceBehavior(
03 InstanceContextMode:=InstanceContextMode.Single)>
04 Public Class CalculatorService
05
06 <OperationContract()>
07 Public Function Calculate(ByVal op1 As Double,
08 ByVal op As String, ByVal op2 As Double) As Double …
24 End Function
25
26 End Class
You need to decrease the response time of the service. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
What should you do?
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that uses the Entity Framework.
You create an Entity Data Model (EDM) named Model. You need to ensure that the Storage Schema Definition Language (SSDL)
of the EDM can be modified without rebuilding the application. What should you do?
Which two actions should you perform?
You use the following declaration to add a Web user control named TestUserControl.ascx to an ASP.NET page named TestPage.aspx.
<uc:TestUserControl ID=”testControl” runat=”server”/>
You add the following code to the code-behind file of TestPage.aspx.
private void TestMethod()
{
…
}
You define the following delegate.
public delegate void MyEventHandler();
You need to add an event of type MyEventHandler named MyEvent to TestUserControl.ascx and attach the page’s TestMethod method to the event.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
What should you do?
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application.
The application contains the following code segment. (Line numbers are included for reference only.)
01 class DataAccessLayer
02 {
03 private static string connString;
04
05 …
06 public static DataTable GetDataTable(string command){
07
08 …
09 }
10 }
You need to define the connection life cycle of the DataAccessLayer class. You also need to ensure that the application uses the minimum number of connections to the database.

What should you do?
A Windows Communication Foundation (WCF) client uses the following service contract. (Line numbers are included for reference only.)
01 <ServiceContract()>
02 Public Interface IService
03
04 <OperationContract()>
05 Function Operation1() As String
06 <OperationContract()>
07 Function Operation2() As String
08
09 End Interface
You need to ensure that all calls to Operation1 and Operation2 from the client are encrypted and signed. What should you do?
