Microsoft 70-503 Exam Syllabus Topics:

Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:

1. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You write the following code segment. (Line numbers are included for reference only.)

The service must meet the following requirements:
You need to set the isolation level for the service.
Which line of code should you insert at line 04?

A) <ServiceBehavior( _ TransactionIsolationLevel:=IsolationLevel.Snapshot)> _
B) <ServiceBehavior( _ TransactionIsolationLevel:=IsolationLevel.Chaos)> _
C) <ServiceBehavior( _ TransactionIsolationLevel:=IsolationLevel.Unspecified)> _
D) <ServiceBehavior( _ TransactionIsolationLevel:=IsolationLevel.Serializable)> _

2. You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. Client applications that run on different platforms access the WCF service.
These applications transmit confidential data to the WCF service. You write the following binding configuration.
....
<binding name="TransportSecurity" >
<security mode="Transport" />
</binding>
...
You need to configure the service for optimum interoperability and optimum security.
Which code fragment should you use?

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

3. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You have successfully created two interfaces: IMyService and IMyServiceClient.
You need to ensure that the service is able to call methods from the client application by using the IMyServiceClient interface.
Which code segment should you use?

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

4. You are creating a Windows Communication Foundation client application by using Microsoft .NET Framework 3.5.
You add the following code segment to a service contract.
[ServiceContract]
interface IDocumentService
{
[OperationContract]
int DeleteDocument(int id);
}
The DeleteDocument method in the service contract takes a long time to execute.
The client application stops responding until the method finishes execution.
You write the following code segment to create an instance of a service proxy in the client application.
(Line numbers are included for reference only.)
01 static void Main() 02 {
03 DocumentServiceClient client= new DocumentServiceClient();
05 }
06 static void ProcessDeleteDocument(IAsyncResult result)
07 {
06 ...
09 }
You need to ensure that the service methods are called asynchronously.
What should you do?

A) Insert the following code segment at line 04:
IAsyncresult result = client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
int count=client.EndDeleteDocument(result);
Insert the following code segment at line 06:
result.AsyncWaitHandle.WaitOne();
B) Insert the following code segment at line 04:
client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
Insert the following code segment at line 06:
int count=(result.AsyncState as Documentserviceclient).EndDeleteDocument(result);
C) Insert the following code segment at line 04:
client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
Insert the following code segment at line 06:
int count=(result.AsyncState as Documentserviceclient).EndDeleteDocument(null);
D) Insert the following code segment at line 04:
client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
Insert the following code segment at line 06:
result.AsyncWaitHandle.WaitOne();
int count=(result as Documentserviceclient).EndDeleteDocument(result)

5. You are creating a distributed application by using Microsoft .NET Framework 3.5.
The application uses the Windows Communication Foundation model.
You need to ensure that the following requirements are met:
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A) <bindings> <wsHttpBinding> <binding name="main"> <security
mode="TransportWithMessageCredential <message clientCredentialType="None7>
</security> </binding> </wsHttpBindingx/bindings>
B) <bindings>
<wsHttpBinding>
<binding name="main">
<security mode="TransportWithMessageCredential <message
clientCredentialType="None"/> </security> </binding> </wsHttpBindingx/bindings>
C) <bindings> <netTcpBinding> <binding name="main">
<security mode="TransportWithMessageCredential <message
clientCredentialType="Certificate7>
</security> </binding> </netTcpBindingx/bindings>
> </security> </binding> </wsHttpBinding></
> transport clientCredentialType="Certificate" />
> transport clientCredentialType="Windows" />
> transport clientCredentialType="Certificate" />
D) <bindings> <wsHttpBinding> <binding name="main"> <security mode="TransportWithMessageCredential bindings>
