1. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
The service will be hosted on a Web server that hosts other Microsoft ASP.NET applications.
You need to enable service model extension (.svc) for the W3SVC/l/ROOT/SampleApp directory and its subdirectories.
Which command should you use?

A) ServiceModelReg.exe -s: W3SVC/1/ROOT/SatripleApp
B) ServiceModelReg.exe - k: W3SVC/l/ROOT/SampleApp
C) ServiceModelReg.exe - i: W3SVC/l/ROOT/SampleApp
D) ServiceModelReg.exe - sn: W3SVC/l/ROOT/SampleApp

2. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment for the service implementation. (Line numbers are included for reference only.)
01 Public Sub PutMessage(ByVal msg As Message)

04 End Sub You need to retrieve the content from the received message body and store it in the variable named value.
Which code segment should you insert at line 03?

3. You create a stateless, thread-safe service by using Microsoft .NET Framework 3.5.
You use the Windows Communication Foundation model to create the service. Load testing reveals that the service does not scale above 1,000 concurrent users. You discover that each call to the service instantiates a new service instance. You also discover that these service instances are expensive to create. You need to ensure that 5,000 concurrent users can access the service.
Which code segment should you use?

A) <ServiceBehavior(_ InstanceContextMode:=lnstanceContextMode.PerCall, _ConcurrencyMode:=ConcurrencyMode.Reentrant)> _
B) <ServiceBehavior(_
lnstanceContextMode:=lnstanceContextMode.Single, _ConcurrencyMode:=ConcurrencyMode.Reentrant)> _
C) <ServiceBehavior(_ lnstanceContextMode:=lnstanceContextMode.Single, _ConcurrencyMode:=ConcurrencyMode.Multiple)> _
D) <ServiceBehavior(_ InstanceContextMode:=lnstanceContextMode.PerCall, _ConcurrencyMode:=ConcurrencyMode.Multiple)> _

4. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment.

The service uses a transactional binding. The TransactionFlow property for the binding is set to True. You need to ensure that the MyMethod method meets the following requirements: Which code segment should you insert at line 04?

A) <OperationBehavior(TransactionScopeRequired:=False)> _ <TransactionFlow(TransactionFlowOption.Mandatory)> _
B) <OperationBehavior(TransactionScopeRequired:=False)> _ <TransactionFlow(TransactionFlowOption.Allowed)> _
C) <OperationBehavior(TransactionScopeRequired:=True)> _ <TransactionFlow(TransactionFlowOption.Allowed)> _
D) <OperationBehavior(TransactionScopeRequired:=True)> _<TransactionFlow(TransactionFlowOption.Mandatory)> _

5. You are creating 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.)

If the existing operation contract is unable to process a request made to the service, a generic operation contract must attempt to process the request.
You need to create the generic operation contract.
Which code segment should you insert at line 07?

A) <OperationContract(Action:="*")> _
Sub ProcessOthers(ByVal msg As Message)
B) <OperationContract(Action:="Default")> _ Sub ProcessOthers()
C) <OperationContract(Action:="Default")> _ Sub ProcessOthers(ByVal msg As Message)
