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

1. You develop a Windows Communication Foundation (WCF) service that contains the following code segment. (Line numbers are included for reference only.)

You need to ensure that all service endpoints are available to client applications. Which code segment should you insert at line 04?

A) Option B
B) Option D
C) Option A
D) Option C

2. You are debugging a Windows Communication Foundation (WCF) service. The service uses signed and encrypted messages.
You need to configure logging so that you can read the contents of the messages.
What should you do?

A) Set maxMessagesToLog to 10.
B) Set logMessageAtServiceLevel to true.
C) Set maxSizeMessagesToLog to 10
D) Set logMessageAtTransportLevel to true.

3. A WCF service code is implemented as follows. (Line numbers are included for reference only.)
01 <ServiceContract()> 02 <ServiceBehavior( 03 InstanceContextMode:=InstanceContextMode.Single)> 04 Public Class CalculatorService 05 06 <OperationContract()> 07 Public Function Calculate(ByVal op1 As Double, 08 ByVal op As String, ByVal op2 As Double) As Double & 24 End Function 25 26 End Class
You need to decrease the response time of the service.
What are two possible ways to achieve this goal (Each correct answer presents a complete solution? Choose two.)

A) Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel.
B) Require the clients to use async operations when calling the service.
C) Change the service behavior to the following. <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Multiple)>
D) Change the service behavior to the following. <ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>

4. You are creating a Windows Communication Foundation (WCF) service that is implemented as folks. (Line numbers are included for reference only.)

You need to ensure that the sack trace details of the exception are not included in the error information sent to the client. What should you do?

A) After line 05, add the following line.
<FaultContract(GetType(FaultException(CX Order)))>
Replace line 11 with the following line.
Throw New FaultException(CX Order)(
anOrder, "Divide by zero exception")
B) Replace line 11 with the following line.
Throw New FaultException(C Order)(anOrder, exToSthng0)d
C) Replace line 11 with the following line.
Throw
D) After line 05, add the following line.
'cFaultContract(GetType(FautException(Of Order)))>
Replace line 11 with the following line.
Throw ex

5. A client application calls a Windows Communication Foundation (WCF) service with a proxy class that was generated by Visual Studio.
The service binding was changed from wsHttpBinding to basicHttpBinding. The method signatures in the service contract are changed.
After these changes, the client application receives errors when calling methods on the service.
You need to ensure that the client can invoke methods on the service successfully.
What should you do?

A) Update the configuration file to use basicHttpBinding.
B) Copy the configuration file elements under the <system.servicelviodel> element from the service back to the client.
C) Update the service reference.
D) Enable anonymous authentication for the service.
