Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4 Sample Questions:

1. You develop a Windows Communication Foundation (WCF) service. You enable all
performance counters and run multiple calls to the service.
The service must isolate session data for each user.
You need to monitor the instancing behavior used in the service.

A) ASP.NET State Service\State Server Sessions Total
B) ASP.NET State Service\State Server Sessions Active
C) ServiceModelService 4.0.0.0\Instances
D) ServiceModelService 4.0.0.0\Calls

2. You are developing a client that sends several types of SOP messages to a Windows Communication Foundation (WCF) service method named PostData PostData is currently defined as follows:
[OperationContract?
void PostData(Order data);
You need to modify PostData so that it can receive any SO6P message which code segment should you use

A) [OperaionContract] void PostDaa(BodyWriter data);
B) (OperationContract(1sOneWay = true, Action "v', ReplyAction = ".') addPostData(BodyWriterdata);
C) [OperaionContract0sOneWay true, Action = 'v', ReplyAction void PostData(Order data);
D) [OperationContract] void PostDaa(Message data);

3. A Windows Communication Foundation (WCF) service is required to log all authorization attempts to the Windows Event Log.
You need to configure a behavior and apply it to the service to support this requirement.
Which behavior should you configure and apply?

A) serviceAuthorization
B) serviceAuthenticationManager
C) serviceSecurityAudit
D) serviceCredentials

4. You are developing a Windows Communication Foundation (WCF) REST service to provide access to a library book catalog. The following code segment defines the service contract. (Line numbers are included for reference only.)

Library patrons want the ability to search the catalog by title.
You need to ensure that the GetBookByTitle method is exposed as a service method.
Which code segment should you insert at line 04?

A) <WebGet(UriTemplate:="Book/{title}")>
B) <WebGet(UciTemplate:-"Book/{titleToSeacch)")>
C) <WebGet(UriTemplate:-"{titleToSearch}")>
D) <WebGet(UriTemplate:="BookByTitle/{title)")>

5. You are creating a Windows Communication Foundation (WCF) service that accepts messages from clients when they are started. The message is
defined as follows.
<MessageContract()>
Public Class Agent
Public Property CodeName As String
Public Property SecretHandshake As String
End Class
You have the following requirements:
The CodeName property must be sent in clear text. The service must be able to verify that the property value was not changed after being sent by the client.
The SecretHandshake property must not be sent in clear text and must be readable by the service.
What should you do?

A) Add an ImmutableObject attribute to the CodeName property and set its value property to True. Add a Browsable attribute to the SecretHandshake property and set its value to False.
B) Add a MessageBodyMember attribute to the CodeName property and set the ProtectionLevel to Sign. Add a MessageBodyMember attribute to the SecretHandshake property and set the ProtectionLevel to EncryptAndSign.
C) Add an XmlText attribute to the CodeName property and set the DataType property to Signed. Add a PasswordPropertyText attribute to the SecretHandshake property and set its value to True.
D) Add a DataProtectionPermission attribute to the each property and set the ProtectData property to True.
