You are creating an application in Windows Communication Foundation (WCF) by using Microsoft.NET Framework 3.5.
You need to ensure that the client application communicates with the service by using a duplex contract.
Which five actions should you perform? (To answer, move the five appropriate actions from the list of actions to the answer area, and arrange them in the correct order.)

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The WCF service will validate certificates to authorize
client applications. You write the following code segment. Class Store Implements IStore Public Sub RemoveOrder(ByVal ordered As Integer) _
Implements IStore. RemoveOrder End Sub End Class You need to ensure that only
those client applications that meet the following criteria can access the RemoveOrder method: "AdminUser" is the subject in the client certificate.
"1 bf47e90O0acf4c0089cda65e0aadcf1 cedd592" is the thumbprint in the client certificate. What should you do?

• A. Decorate the RemoveOrder method by using the following attribute. <PrincipalPermission(SecurityAction. Demand, _Name:="CN=AdminUser;1bf47e90100acf4c0089cda65e0aadcf1cedd592")> _ Initialize the serviceAuthorization element of the service behavior in the following manner. <serviceAuthorization principalPermissionMode="UseAspNetRoles7>
• B. Decorate the RemoveOrder method by using the following attribute.
  <PrincipalPermission(SecurityAction. Demand,
  _Role:="CN=AdminUser,1bf47e9000acf4c0089cda65eOaadcf1cedd592")> _ Initialize the
  serviceAuthorization element of the service behavior in the following manner.
  <serviceAuthorization principalPermissionMode="Windows7>
• C. Decorate the RemoveOrder method by using the following attribute.
  <PrincipalPermission(SecurityAction. Demand,
  _Name:="AdminUser;1bf47e90C0acf4c0089cda65e0aadcf1cedd592")> _ Initialize the
  serviceAuthorization element of the service behavior in the following manner.
  <serviceAuthorization principalPermissionMode="Windows7>
• D. Decorate the RemoveOrder method by using the following attribute.
  <PrincipalPermission(SecurityAction. Demand,
  _Role:="AdminUser,1 bf47e90100acf4c0089cda65e0aadcf1 cedd592")> _ Initialize the
  serviceAuthorization element of the service behavior in the following manner.
  <serviceAuthorization principalPermissionMode="UseAspNetRoles7>

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5.
You create an instance of the ServerHost class. You plan to host the WCF service in a Windows service.
You need to link the lifetime of the WCF service to the lifetime of the Windows service.
Which three actions should you perform on the instance of the ServerHost class? (Each correct answer presents part of the solution. Choose three.)

• A. Override the OnStop method.
• B. Override the InitializeLifetimeService method.
• C. Subscribe to the Faulted event.
• D. Override the OnStart method.
• E. Override the RequestAdditionalTime method.
• F. Override the GetLifetimeService method.

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment.

You need to ensure that when the MyMethod method is called, the service is the root of a transaction.
Which code segment should you insert at line 08?

• A. <OperationBehavior(TransactionScopeRequired:=False)> _ <TransactionFlow(TransactionFlowOption.NotAllowed)> _
• B. <OperationBehavior(TransactionScopeRequired:=True)> _ <TransactionFlow(TransactionFlowOption.NotAllowed)> _
• C. <OperationBehavior(TransactionScopeRequired:=False)> _ <TransactionFlow(TransactionFlowOption.Mandatory)> _
• D. <OperationBehavior(TransactionScopeRequired:=True)> _ <TransactionFlow(TransactionFlowOption.Allowed)> _

You are creating a Windows Communication Foundation application by using Microsoft .NET Framework 3.5. The application must consume an ATOM 1.0 feed published at http://localhost:8000/BlogService/GetBlog.
You write the following code segment. (Line numbers are included for reference only.)
01 Uri address = new 02 Uri("http://localhost:8000/BlogService/GetBlog");
04 Console.WriteLine(feed.Title.Text);
You need to ensure that the application prints the title of the feed.
Which code segment should you insert at the line 03?

• A. Syndicationltem item = new Syndicationltem();
  item.BaseUri = address;
  SyndicationFeed feed = new SyndicationFeed();
  feed. Items = new Syndicationltem[] { item };
• B. SyndicationFeed feed = new SyndicationFeed0;feed.BaseUri = address;
• C. Syndicationltem item = Syndicationltem.Load(address);
  SyndicationFeed feed = new SyndicationFeed();
  feed. Items = new Syndicationltem[] { item };
• D. SyndicationFeed feed = SyndicationFeed.Load(address);
