Microsoft 070-503 : TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation

You are creating an application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application. The YourUserNamePasswordValidator class is implemented in the host application of the WCF service. The host application is named YourServiceHost.exe. You write the following code segment.
namespace YourSecureService
{
class YourUserNamePasswordValidator : UserNamePasswordValidator {
public override void Validate(string userName, string password)
{
...
}}
}
You need to perform custom validation of the user name and password by using the YourUserNamePasswordValidator class. What should you do?

• A. Set the netTcpBinding binding in the following manner. <security mode="Transport">
  <transport
  clientCredentialType="UserName" /></security> Set the service behavior by using the
  following credentials.
  <userNameAuthentication customUserNamePasswordValidatorType="YourSecureService.
  YourUserNamePasswordValid ator " userNamePasswordValidationMode="Custom"/>
• B. Set the wsHttpBinding binding in the following manner. <security mode="Message">
  <transport
  clientCredentialType="UserName" /></security> Set the service behavior by using the
  following credentials.
  <userNameAuthentication
  customUserNamePasswordValidatorType="YourUserNamePasswordValidator,
  YourServiceHo st" userNamePasswordValidationMode="Custom"/>
• C. Set the wsHttpBinding binding in the following manner. <security mode="Message">
  <message
  clientCredentialType="UserName" /></security> Set the service behavior by using the
  following credentials.
  <userNameAuthentication customUserNamePasswordValidatorType="YourSecureService.
  YourUserNamePasswordValid a or,YourServiceHost"
  userNamePasswordValidationMode="Custom"/>
• D. Set the wsHttpBinding binding in the following manner. <security mode="Message">
  <message
  clientCredentialType="UserName" /></security> Set the service behavior by using
  thefollowing credentials.
  <userNameAuthentication
  customUserNamePasswordValidatorType="YourSecureService.YourUserNamePasswordV
  alid ator"
  userNamePasswordValidationMode="Custom"/>

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

You need to ensure that concurrent calls are allowed on the service instance.
Which code segment should you insert at line 06?

• A. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Reentrant, _ ReleaseServicelnstanceOnTransactionComplete:=True)> _
• B. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Reentrant, _ ReleaseServicelnstanceOnTransactionComplete:=False)> _
• C. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Multiple, _ ReleaseServicelnstanceOnTransactionComplete:=False)> _
• D. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Multiple, _ ReleaseServicelnstanceOnTransactionComplete:=True)> _

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You configure a binding to enable streaming. You need to ensure that the client application is able to stream large XML files to the WCF service.
Which operation contract should you create?

• A. [OperationContract]void UploadFile(Stream xmlData);
• B. [OperationContract]void UploadFile(XmlWriter xmlData);
• C. [OperationContract]void UploadFile(StreamWriter xmlData);
• D. [OperationContractjvoid UploadFile(byte[] xmlData);

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 A
• C. Option B
• D. Option C

You create a Windows Communication Foundation service by using Microsoft .NET
Framework 3.5. You set up tracing for the service.
The tracing fails because of an error in the service configuration. You need to identify the cause of the error.
What should you do?

• A. Set the enableLogKnownPii attribute to true in the machine, config file.
• B. Examine the system event log.
• C. Examine the security event log.
• D. Examine the application event log.
