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

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to publish metadata programmatically.
Which two code segments should you use? (Each correct answer presents a complete solution. Choose two.)

• A. Option B
• B. Option D
• C. Option C
• D. Option A

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You have successfully defined a service contract named IManageOrders. You write the following code segment.

You need to create a fault contract for the MarkOrderClosed method on the IManageOrders service contract. Which code segment should you add?

• A. [FaultContract(typeof(FaultException))]
• B. [FaultContract(typeof(Exception))]
• C. [FaultContract(typeof(DataFault))]
• D. [FaultContract(typeof(SqlException))]

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 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"/>
• B. 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"/>
• 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 are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to configure a single service endpoint with the following logical and physical addresses:
Which configuration setting should you use?

• A. Option B
• B. Option D
• C. Option C
• D. Option A

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.)

You need to ensure that each time a client application calls the Open() method, a new service instance is created.
Which code segment should you insert at line 03?

• A. [OperationBehavior(ReleaseInstanceMode=ReleaseInstanceMode.None)]
• B. [OperationBehavior(AutoDisposeParameters=true)]
• C. [OperationBehavior(ReleaseInstanceMode=ReleaseInstanceMode.BeforeCall)]
• D. [OperationBehavior(TransactionScopeRequired=true)]
