Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:
1. You are creating a distributed application with Windows Communication Foundation by using Microsoft .NET Framework 3.5.
The distributed application topology includes client applications, routers, and services. Communication between the client applications and the services require authentication, confidentiality, and integrity.
You need to ensure that routers are not able to read the contents of the messages. You must achieve this goal without customizing the binding configuration.
Which binding should you use?
A) NetPeerTcpBinding
B) WSHttpBinding
C) NetNamedPipeBinding
D) NetTcpBinding
2. You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5.
You need to use a custom service host to host the WCF service in Windows Activation Services (WAS).
What should you do?
A) Create a custom service host factory that instantiates the custom service host. Include a reference to this factory in the .svc file.
B) Add code to instantiate the custom service host from within the main procedure of the WCF service.
C) Add a reference to the custom service host in the web.config file.
D) Write hosting code for the WCF service.
3. You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application exposes a Windows Communication Foundation (WCF) Web service. The Web service is consumed by third-party applications. You need to ensure that the WCF service provides interoperable and secure end-to-end communications. What should you do?
A) Use the netNamedPipeBinding binding along with the message-level and the transport-level securities.
B) Use the netTcpBinding binding along with the message-level security.
C) Use the basicHttpBinding binding along with the transport-level security.
D) Use the wsHttpBinding binding along with the message-level security.
4. You are creating a Windows Communication Foundation application by using Microsoft .NET Framework 3.5. The application must consume an ATOM 1.0 feed published at http://localhost:8000/BlogService/GetBlog. You write the following code segment. (Line numbers are included for reference only.)
You need to ensure that the application prints the title of the feed.
Which code segment should you insert at the line 02?
A) Dim item As Syndicationltem = SyndicationItem.Load(address)
Dim feed As New SyndicationFeed()
feed.Items = New Syndicationltem() {item}
B) Dim feed As SyndicationFeed = New SyndicationFeed()
feed.BaseUri = address
C) Dim item As New SyndicationItem()
item.BaseUri = address
Dim feed As New SyndicationFeed()
feed.Items = New Syndicationltem() {item}
D) Dim feed As SyndicationFeed = SyndicationFeed.Load(address)
5. You are creating a remote database management application by using Microsoft Windows Forms and Microsoft .NET Framework 3.5. You use the Windows
Communication Foundation model to create the application. You write the following code segment. (Line numbers are included for reference only.)
01 public class QueryAnalyzerService :
02 IQueryAnalyzerService, IDisposable {
04 public void Open() {
05}
06 public void ExecuteSql(string sql) {
07...
08!
09 public void Close() {
10...
11}
12 public void Disposed
13...
14}
15...
16}

A) [OperationBehavior( ReleaselnstanceMode=ReleaselnstanceMode.BeforeCall))
B) [OperationBehavior( AutoDisposeParameters=true)]
C) [OperationBehavior( ReleaselnstanceMode=ReleaselnstanceMode.None)]
