Microsoft 070-513 valid exam dumps : TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4

A Windows Communication Foundation (WCF) service that handles corporate accounting must be changed to comply with government regulations of auditing and accountability
You need to configure the WCF service to execute under the Windows logged-on identity of the calling application.
What should you do?

• A. Within the service configuration, add a serviceSecurityAudit behavior to the service, and set serviceAuthorizationAuditLevel to SuccessOrFailure
• B. Within the service configuration, add a ServiceAuthenticationManager behavior to the service, and set ServiceAuthenticationManagerType to Impersonate.
• C. Within the service configuration, add a ServiceAuthorization behavior to the service, and set ImpersonateCallerForAulOperations to true.
• D. Within the service configuration, add a ServiceCredentials behavior to the service, and set type to Impersonate

You are creating a windows Communication Foundation (WCF) service to process orders. The data contract for the order is defined as follows:
[DataContract] public class Order { ... [DataMemberl public string CardHolderName { get; set; [DataMember] public string CreditCardNumber { get; set; } }
You have the following requirements
- Enable the transmission of the contents of Order from the clients to the service. - Ensure that the contents of CreditCardNumber are not sent across the network in clear text. - Ensure that the contents of CreditCardNumber are accessible by the service to process the order.
You need to implement the service to meet these requirements.
What should you do?

• A. Change the data type of CreditCardNumber from string to SecureString
• B. Convert the DataContract to a MessageContract and set the ProtectionLevel property to SignAndEncrypt
• C. Implement the CreditCardNumber property getter and setter. In the setter, run the value of the CreditCardNumber through the MD5CryptoServiceProvider class TransformBlock method
• D. Add a DataProtectionPermission attribute to the CreditCardNumber property and set the ProtectData property to true.

DRAG DROP
You have a client application that uses an existing Windows Communication Foundation (WCF) service. The client application contains a defined EndpointAddress object named endpointAddress.
A class named ServiceClient is generated by using the Svcutil tool to invoke the WCF service. Instances of the ServiceClient class are created as follows:
ServiceClient client = new ServiceClient(CreateBinding(), endpointAddress);
The client application must meet the following requirements:
- Optimize message-level security when transporting both text files and large files. - Provide transport-level security by using the HTTPS protocol.
You need to create the code for the CreateBinding() method.
Which four code segments should you use in sequence? (To answer, move the appropriate four code segments from the list of code segments to the answer area and arrange them in the correct order.)

You are developing a data contract for a Windows Communication Foundation (WCF) service.
The data in the data contract must participate in round trips. Strict schema validity is not required.
You need to ensure that the contract is forward-compatible and allows new data members to be added to it.
Which interface should you implement in the data contract class?

• A. IExtensibleObject(Of T)
• B. IExtension(Of T)
• C. IExtensibleDataObject
• D. ICommunicationObject

A Windows Communication Foundation (WCF) application exposes a service as a SOAP endpoint for consumption by cross-platform clients. During integration testing, you find that one of the clients is not generating the correct messages to the WCF application.
In order to debug the issue and fix the communication, you need to configure the service to log messages received from the client.
What should you do?

• A. Set an etwTracking behavior on the service and configure a listener for the System.ServiceModel trace source.
• B. Set an etwTracking behavior on the service and configure a listener for the System.ServiceModel.MessageLogging trace source.
• C. Enable messageLogging in the System.ServiceModel diagnostics element configuration and configure a listener for the System.ServiceModel.MessageLogging trace source.
• D. Enable messageLogging in the System.ServiceModel diagnostics element configuration and configure a listener for the System.ServiceModel trace source.
