Microsoft 070-513 Exam Syllabus Topics:

Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4 Sample Questions:

1. 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/javaScript" src="/Services/Contoso.svc/js" />
You need to retrieve the debug version of the service JavaScript.
What should you do?

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

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

3. A Windows Communication Foundation (WCF) service has a callback contract. You are developing a client application that will call this service.
You must ensure that the client application can interact with the WCF service.
What should you do?

A) On the OperationContractAttribute, set the ReplyAction property value to the endpoint address of the client.
B) On the OperationContractAttribute, set the AsyncPattern property value to true.
C) On the client, create a proxy derived from DuplexClientBase<TChannel>.
D) On the client, use GetCallbackChannel<T>.

4. A Windows Communication Foundation (WCF) solution exposes the following service over a TCP binding. (Line numbers are included for reference only.)
01 [ServiceContract]
02 [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
03 public class DataAccessService
04 {
05 [OperationContract]
06 public void PutMessage(string message)
07 {
08 MessageDatabase.PutMessage(message);
09 }
10 [OperationContract]
11 public string[] SearchMessages(string search)
12 {
13 return MessageDatabase.SearchMessages(search);
14 }
15 }
MessageDatabase supports a limited number of concurrent executions of its methods.
You need to change the service to allow up to the maximum number of executions of the methods of MessageDatabase. This should be implemented without preventing customers from connecting to the service.
What should you do?

A) Add a throttling behavior to the service, and configure the maxConcurrentCalls.
B) Add a throttling behavior to the service, and configure the maxConcurrentSessions.
C) Change the service behavior as follows. [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.Single)]
D) Change the service behavior as follows. [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, InstanceContextMode = InstanceContextMode.PerSession)]

5. You develop a Windows Communication Foundation (WCF) service that interacts with Microsoft Message Queuing (MSMQ).
The service requires sessions. You need to create a custom binding that enables messages sent to the queue to be viewed when you are using a listener tool.
Which binding elements should you use?

A) msmqIntegrationTransport and textMessageEncoding in this order
B) msmqTransport and textMessageEncoding in this order
C) textMessageEncoding and msmqIntegrationTransport in this order
D) textMessageEncoding and msmqTransport in this order
