Microsoft 70-513 Value Pack (Frequently Bought Together)

You are creating an ASP NET web application that hosts several Windows Communication Foundation (WCF) services the services have ASP.NET Compatibility Mode enabled.
Users authenticate with the Web application by using a cookie-based ASR NET Forms Authentication model. You add a service tile named Authentication. svc that contains the following code segment
<%@ SenviceHost Servicee"System
Web Application Services Authentication Service"Factory="System.Web.ApplicationServices.AppicationServicesHostFactory' %>.
You need to ensure that users can access the WCF services without having to re-authenticate.
Which two configuration settings should you add? (Each is part of a complete solution. Choose two.)

• A. Add a service endpoint with basicHttpBinding for the contract System.WebApplicationServices.AuthenticationService.
• B. Add a custom service behavior named AuthenticationServiceTypeBehaviors with a serviceAuthenticationManager element that has serviceAuthenticationManagerType set to System Web Security. SQL Membership Provider
• C. In the system web.extensions/scripting/webServices/authenticationService element, set the enabled attribute to true.
• D. In the system web.extensions/scripting/webServices/profileService element, set the enabled attribute to true.

You are implementing a Windows Communication Foundation (WCF) service contract named IContosoService in a class named ContosoService. The service occasionally fails due to an exception being thrown at the service.
You need to send the stack trace of any unhandled exceptions to clients as a fault message.
What should you do?

• A. For each OperationContract exposed by IContosoService, apply the following attribute.
  [FaultContract(typeof(Exception))]
• B. In the application configuration file on the client, add the following XML segment to the
  system.serviceModel/behaviors configuration section group.
  <endpointBehaviors>
  <behavior name=" debug ">
  < callback Debug includeExceptionDetailInFaults="true" />
  </behavior>
  </endpointBehaviors>
  Associate the debug behavior with any endpoints that need to return exception details.
• C. Apply the following attribute to the ContosoService class.
  [ServiceBehavior(IncludeExceptionDetailInFaults = true)]
• D. In the application configuration file on the service and all the clients, add the following
  XML segment to the system.diagnostics/sources configuration section group.
  <source name="System.ServiceModel" switchValue="Error" propagateActivity="true">
  <listeners>
  <add name="ServiceModelTraceListener"
  initializeData="app_tracelog.svclog"
  type="System.Diagnostics.XmlWriterTraceListener" />
  </listeners>
  </source>

A Windows Communication Foundation (WCF) service has a callback contract. You are developing a client application that will call this service.
You must ensure that the client application can interact with the WCF service.
What should you do?

• A. On the client, use GetCallbackChannel<T>.
• B. On the OperationContractAttribute, set the AsyncPattern property value to true.
• C. On the OperationContractAttribute, set the ReplyAction property value to the endpoint address of the client.
• D. On the client, create a proxy derived from DuplexClientBase<TChannel>.

You are creating a Windows Communication Foundation (WCF) service that accepts claims-based tokens.
You need to ensure that the service can use claims from trading partners even though there are variations on naming for the same elements.
Which two actions should you perform? (Each correct answer presents part of the solution Choose two.)

• A. Register a custom Service Authorization Manager that implements Check Access In this method, use System. Convert. Change Type to transform the incoming claim set to a Windows Claim Set type.
• B. Register an Authorization Policy that maps external claims to an internal Claim Set.
• C. Apply a Principal Permission attribute on the operation with the required claims listed in the Roles property.
• D. Within the operation, verify the presence of the required claims in the current Authorization Context

Windows Communication Foundation (WCF) application uses a data contract that has several data members.
You need the application to throw a Serialization Exception if any of the data members are not present when a serialized instance of the data contract is deserialized.
What should you do?

• A. Set the lsRequired property of each data member to true.
• B. Add the Known Type attribute to the data contract.
  Set the Order property of each data member to unique integer value.
• C. Set the Emit Default Value property of each data member to false.
• D. Add the Known Type attribute to the data contract.
  Set a default value in each of the data member declarations.
