Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:
You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The WCF service must authenticate the client applications by validating credit card numbers and expiry dates.
You write the following code segment. (Line numbers are included for reference only.)
You need to implement custom authentication for the WCF service. Which code segment should you insert at line 10?
- A. Option B
- B. Option D
- C. Option A
- D. Option C
Correct Answer: C 🗳️
You are creating an endpoint for a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the endpoint by using a custom binding.
You write the following code segment.
You need to prevent the custom binding from making a persistent connection to the service endpoint.
Which code segment should you use?
- A. Option B
- B. Option D
- C. Option A
- D. Option C
Correct Answer: C 🗳️
You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You write the following code segment to create a service contract. (Line numbers are included for reference only.)
You need to ensure that the client applications always use a binding that supports sessions.
Which code segment should you insert at line 01?
- A. <ServiceContract(SessionMode:=SessionMode.Allowed)> __
- B. <ServiceContract(ProtectionLevel:=ProtectionLevel.EncryptAndSign)> __
- C. <ServiceContract(ProtectionLevel:=ProtectionLevel._ EncryptAndSign,SessionMode:=SessionMode.Allowed)> __
- D. <ServiceContract(SessionMode:=SessionMode.Required)>
Correct Answer: D 🗳️
You are creating a client application that will call a Windows Communication Foundation service. The service was created by using Microsoft .NET Framework
3.5. You write the following code segment.
You plan to share the validation logic between the client application and the WCF service.
You need to generate a client-side service proxy that includes the validation logic.
Which four tasks should you perform? (Each correct answer presents part of the solution. Choose four.)
- A. In the Service project, add a reference to the Class Library project.
- B. In the Client project, use the Add Web Reference dialog box to reference the service.
- C. Create a Class Library project for the DataContract classes.
- D. In the Client project, use the Add Reference dialog box to add a project reference to the Service project.
- E. In the Client project, use the Add Service Reference dialog box to reference the service.
- F. In the Client project, add a reference to the Class Library project.
Correct Answer: A,C,E,F 🗳️
What binding should be used to support sessions?
- A. [ServiceContract(ProtectionLevel=ProtectionLevel.EncryptAndSign)]
- B. [ServiceContract(SessionMode = SessionMode.Required)]
- C. [ServiceContract(SessionMode = SessionMode.Allowed)]
- D. [ServiceContract(
ProtectionLevel=ProtectionLevel.EncryptAndSign
SessionMode= SessionMode.Allowed)
