70-513 無料問題集「Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4」
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?

You are developing a new version of an existing message contract named CustomerDetailsVersion1.
The new version of the message contract must add a Department field of type String to the SOAP header.
You create a new class named GustomerDetailsVersion2 that inherits from CustomerDetailsVersion1.
You need to ensure that all client applications can consume the service.
Which code segment should you use?

You are using tracing to diagnose run-time issues when you look at the traces for the service in Svc Trace viewer exe, you see what is shown in the exhibit (Click the Exhibit button)
The exception trace is selected in Svc Trace reviewer exe.
You need to interpret the trace results to determine where the error occurred and what to do next.

You are implementing a Windows Communication Foundation (WCF) client application that consumes the ICatalog and lCatalog2 service interfaces
You need to ensure that the client discovers services implementing these interfaces
The services may already be online or may come online within a 30 second time limit
How should you use WCF Discovery to accomplish this?

A Windows Communication Foundation (WCF) solution uses two services to manage a shopping cart. Service A processes messages containing line items that total between $0 and $500. Service B processes messages containing line items that total more than $500.
All messages are of equal importance to the business logic.
You need to route incoming messages to the appropriate services by using WCF routing.
Which two message filters should you add to the router? (Each correct answer presents part of the solution. Choose two.)

You develop a Windows Communication Foundation (WCF) service that uses basic authentication for client credentials. This service is currently configured to use message security.
The service is hosted on a server in workgroup mode.
Users report that their passwords are stolen when they use public computers. You need to ensure that messages are secure and users are authenticated.
You prevent the service from being called over HTTP through Microsoft Internet Information Services (IIS) configuration.

An ASP.NET application hosts a RESTful Windows Communication Foundation (WCF) service at /Services/Contoso.svc. The service provides a JavaScript resource to clients. You have an explicit reference to the JavaScript in your page markup as follows.
<script type="text/javaScript" src="/Services/Contoso.svc/js" />
You need to retrieve the debug version of the service JavaScript.

You are developing a Windows Communication Foundation (WCF) service to replace an existing A5MX Web service.
The WCF service contains the following code segment. (Line numbers are included for reference only.)
The existing Web service returns the EmployeeID as an attribute of the EmployeeInfo element in the response XML.
You need to ensure that applications can consume the service without code changes in the client.

A Windows Communication Foundation (WC9 service implements a contract with one-way and requestreply operations.
The service is exposed over a TCP transport Clients use a router to communicate with the service. The router is impemented as follows.
(Line numbers are included for reference only.)
01 Dim host As ServiceHost = 02 New ServiceHost(GetType(RoutingService)) 03 hostAddServiceEndpoint(
04 GetType(lSimplexDatagramRouter),
05 New NetTcpBinding0, "net.tcp://localhostlRouter"

07 Dim lep As List(Of ServiceEndpoint) =
08 New List(Of SenviceEndpointx)

18 Dim rc As RoutingConfiguration = New RoutingConfiguration()
19 rc . FitterTable.Add(New Matctf4llMessageFilter0, lep)
20 host. Description. Behaviors.Add(New RoutingBehavior(rc)) Request-reply operations
are failing.
You need to ensure that the router can handle one-way and request-reply operations.
