You are creating a Windows Communication Foundation (WCF) service that implements operations in a RESTful manner. You need to add a delete operation
You implement the delete method as follows. string oid Deleteltems(string id);
You need to configi.re WCF to ci this method when the client calls the service with the HTTP DRETE opera on
What should you do?

• A.  Replace the return type with RemovedActivityktion.
• B.  Replace the sting parameter with a RemovedActivityAction parameter
• C.  Add the Weblnvoke(UriTemplate = "/Items/(idy, Method="DELETE") attribute to the operation
• D.  Add the HttpDelete tribute to the operation

You are developing a Windows Communication Foundation (WCF) service that does not operate on a duplex channel.
You find that operations do not start until all previous operations have finished. The service hosting code contains the following lines.
Dim service = New WarehouseService()
Dim hose = New ServiceHost(service)
You need to ensure that new operations do not wait for previous operations to finish.
Which attribute should you use to decorate the service?

• A.  <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Single) >
• B.  <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Reentrant)>
• C.  <ServiceBehovior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Multiple)>
• D.  <CallbackBehavior( ConcurrencyMode:=ConcurrencyMode.Multiple)>

An ASP.NET application hosts a RESTful Windows Communication Foundation (WCF) service at /Services/Contoso.svc . The service provides a JavaScript resource to clients. You have an explicit reference to the JavaScript in your page markup as follows.
<script type="text/3avaScript" src="/Secvices/Contoso.svc/js" />
You need to retrieve the debug version of the service JavaScript.
What should you do?

• A.  In the <<H>@ Page <*to> header, set the Debug attribute to true.
• B.  In the <<to@ ServiceHost %> header for /Services/Contoso.svc, set the Debug attribute to true.
• C.  In the script tag, append debug to the src attribute.
• D.  In the script tag, add a debug attribute and set its value to true.

You are creating a Windows Communication Foundation (WCF) service.
You have the following requirements:
Messages must be sent over TCP.
The service must support transactions.
Messages must be encoded using a binary encoding.
Messages must be secured using Windows stream-based security.
You need to implement a custom binding for the service.
In which order should the binding stack be configured?

• A.  windowsStreamSecurity tcpTransport binaryMessageEncoding transactionFlow
• B.  transactionFlow binaryMessageEncoding windowsStreamSecurity tcpTransport
• C.  binaryMessageEncoding transactionFlow tcpTransport windowsStreamSecurity
• D.  tcpTransport windowsStreamSecurity transactionFlow binaryMessageEncoding

You are creating a Windows Communication Foundation (WCF) service. The service endpoints change frequently.
On the service, you add a new ServiceDiscoveryBehavior to the Behaviors collection of the ServiceHost Description property.
You need to ensure that client applications can communicate with the service and discover changes to the service endpoints.
What should you do?

• A.  Add a new AnnouncementClient to the Behaviors collection in the client application.
• B.  Add a new ServiceDiscoveryBehavior to the Behaviors collection in the client application.
• C.  Use the FindCriteria class and the UdpDiscoveryEndpoint class to set up the binding in the client application.
• D.  Use the DiscoveryProxy class and the EndpointDiscoveryMetadata class to set up the binding in the client application.
