You are creating a Window s Communication Foundation (WCF) service application. The
application needs to service many clients and requests simultaneously. The application also needs to ensure subsequent individual client requests provide a stateful conversation.
You need to configure the service to support these requirements.
Which attribute should you add to the class that is implementing the service?

• A.[ ServiceBehavior ( InstanceContextMode =
  InstanceContextMode.PerCall,
  ConcurrencyMode = ConcurrencyMode.Multiple )]
• B.[ ServiceBehavior ( InstanceContextMode =
  InstanceContextMode.PerSession,
  ConcurrencyMode = ConcurrencyMode.Single )]
• C.[ ServiceBehavior ( InstanceContextMode =
  InstanceContextMode.PerCall,
  ConcurrencyMode = ConcurrencyMode.Reentrant )]
• D.[ ServiceBehavior ( InstanceContextMode =
  InstanceContextMode.PerSession,
  ConcurrencyMode = ConcurrencyMode.Multiple )]

You are creating a Windows Communication Foundation (WCF) service that accepts messages from clients when they are started. The message is
defined as follows. <MessageContract()> Public Class Agent Public Property CodeName As String Public Property SecretHandshake As String End Class You have the following requirements:
The CodeName property must be sent in clear text. The service must be able to verify that the property value was not changed after being sent by the client.
The SecretHandshake property must not be sent in clear text and must be readable by the service.
What should you do?

• A.Add a MessageBodyMember attribute to the CodeName property and set the ProtectionLevel to Sign. Add a MessageBodyMember attribute to the SecretHandshake property and set the ProtectionLevel to EncryptAndSign.
• B.Add a DataProtectionPermission attribute to the each property and set the ProtectData property to True.
• C.Add an ImmutableObject attribute to the CodeName property and set its value property to True. Add a Browsable attribute to the SecretHandshake property and set its value to False.
• D.Add an XmlText attribute to the CodeName property and set the DataType property to Signed. Add a PasswordPropertyText attribute to the SecretHandshake property and set its value to True.

You have a self-hosted Windows Communication Foundation (WCF) service.
You need to configure the service to provide an X.509 certificate during authentication
What should you use to configure the service?

• A.the SetCertificate method of the X5O9CertificateRecipientServiceCredential class
• B.the Certificate property of the X509CertificatelnitiatorServiceCredential class
• C.the SetCertificate method of the X509CertificatelnitiatorServiceCredential class
• D.the TrustedStoreLocation property of the X5O9CertificateRecipientServiceCredential class

A Windows Communication Foundation (WCF) solution uses two services to manage a shopping cart. Service A processes messages containing line items that total between $0 and $500. Service B processes messages containing line items that total more than $500.
All messages are of equal importance to the business logic.
You need to route incoming messages to the appropriate services by using WCF routing.
Which two message filters should you add to the router? (Each correct answer presents part of the solution. Choose two.)

• A.a message filter with a priority of 0 that will forward all messages to Service B
• B.a message filter with a priority of 100 that will forward all messages to Service B
• C.a message filter with a priority of 100 that will forward messages that total between $0 and $500 to Service A
• D.a message filter with a priority of 0 that will forward messages that total between $0 and $500 to Service A

You develop a Windows Communication Foundation (WCF) RESTful service that provides media streaming services. The service includes the following code. (Line numbers are included for reference only.)

The service must return an XML response.
You need to apply the correct attribute to AddMediaTitle method.
Which code segment should you insert at line 05?

• A.[WebInvoice (ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle .Bare) ]
• B.[WebInvolce (Method= "POST") ]
• C.[WebInvolce(ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped)]
• D.[WebInvoice]
