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

1. You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You create a class named Customer for the WCF service. The Customer class has properties named Id, Name, and BalanceDue.
You plan to convert the Customer class into a data contract.
You need to ensure that only the Id property and the Name property are passed to the client applications.
Which code segment should you use?

A) <DataContract()> _
Public Class Customer
Public Property Id() As Integer
...
End Property
Public Property Name() As String
...
End Property
Private Property BalanceDue() As Double
...
End Property
End Class
B) <DataContract()> _ Public Class Customer <DataMember()> _ Public Property Id() As Integer ... End Property <DataMember()> _ Public Property Name() As String ... End Property <DataMember(EmitDefaultValue:=False)> _ Public Property BalanceDue() As Double ... End Property End Class
C) <DataContract()> _
Public Class Customer
<DataMember()> _
Private Property Id() As Integer
...
End Property
<DataMember()> _
Public Property Name() As String ... End Property Public Property BalanceDue() As Double ... End Property End Class
D) <DataContract()> _ Public Class Customer <DataMember(EmitDefaultValue:=True)> _ Public Property Id() As Integer ... End Property <DataMember(EmitDefaultValue:=True)> _ Public Property Name() As String ... End Property <DataMember()> _ Friend Property BalanceDue() As Double ... End Property End Class

2. You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application consists of the following components:
An ASP.NET Web application that is deployed on a Web server named WEB1 An ASMX Web service that is deployed on an application server named APP1 A Microsoft SQL Server database that is deployed on a database server named SQL1 The ASP.NET application connects to an ASMX Web service. The APP1 server hosts several ASMX Web service applications. The ASMX Web service stores and retrieves data from SQL1.
You need to ensure that the secure communication strategy meets the following requirements:
The communication configuration between WEB1 and APP1 must be secured without other applications being affected. Server authentication and data encryption must be performed between APP1 and SQL1. Which two secure communication protocols should you use? (Each correct answer presents part of the solution. Choose two.)

A) Use Remote Procedure Call encryption between WEB1 and APP1.
B) Use Secure Sockets Layer between APP1 and SQL1.
C) Use Internet Protocol Security between WEB1 and APP1.
D) Use Internet Protocol Security between APP1 and SQL1.
E) Use Secure Sockets Layer between WEB1 and APP1.
F) Use Remote Procedure Call encryption between APP1 and SQL1.

3. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will be exposed for consumption.
You need to ensure that the service supports interoperability with the broadest possible number of Web Service toolkits. The service must also support transport-level Security.
Which configuration setting should you use?

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

4. You are creating a client application by using Microsoft .NET Framework 3.5. The
application consumes an ASMX Web service.
You need to configure the binding to call the methods of the ASMX Web service.
Which binding should you use?

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

5. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following binding configuration in the configuration file. (Line numbers are included for reference only.)
01 <wsHttpBinding>
02 <binding name="ssl">
04 </binding>
05 </wsHttpBinding>
You need to ensure that the following requirements are met:
Which configuration setting should you insert at line 03?

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