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

1. 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) textMessageEncoding and msmqTransport in this order
C) textMessageEncoding and msmqIntegrationTransport in this order
D) msmqTransport and textMessageEncoding in this order

2. You need to modify a client application that consumes a Windows Communication Foundation (WCF) service.
The service metadata is no longer available.
You need to modify the previously generated proxy to include asynchronous calls to the service.
What should you do?

A) Update the service reference with the Generate asynchronous operations option.
B) Create a class with the same name as the previously generated proxy and add the new asynchronous methods as partial methods. Add the new class to a namespace that is different from the original proxy.
C) Create a class with the same name as the previously generated proxy and add the new asynchronous methods. Add the new class to a namespace that is different from the original proxy.
D) Create a partial class for the previously generated proxy and include the new asynchronous methods.

3. A Windows Communication Foundation (WCF) service interacts with the database of a workflow engine. Data access authorization is managed by the database, which raises security exceptions if a user is unauthorized to access it.
You need to ensure that the application transmits the exceptions raised by the database to the client that is calling the service.
Which behavior should you configure and apply to the service?

A) routing
B) serviceSecurityAudit
C) workflowUnhandledException
D) serviceDebug

4. DRAG DROP
You are developing a Windows Communication Foundation (WCF) service that contains a method named ProcessPayments. The service is hosted in Internet Information Services (IIS).
You have the following requirements:
- Create a new instance of the service every time that a client application calls the ProcessPayments method. - Process every call from client applications one at a time.
You need to complete the code for the WCF service.
Which four code segments should you use in sequence? (To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.)

5. HOTSPOT
You are developing a Windows Communication Foundation (WCF) service. You implement a data contract to pass complex data to and from the service. The service includes the following code:

You need to verify the order in which the data is serialized.
For each of the following statements, select True if the statement is true. Otherwise select False.
