Question 41:
You are creating a client application and configuring it to call a Windows Communication Foundation (WCF) service. When the application is deployed, it will be configured to send all messages to a WCF routing service.
You need to ensure that the application can consume the target service after the application is deployed.
What should you do?
A. In the client application, add a service reference to the router service. In the client binding configuration, specify the address of the router service.
B. In the client application, add a service reference to the target service. In the client binding configuration, specify the address of the target service.
C. In the client application, add a service reference to the router service. In the client binding configuration, specify the address of the target service.
D. In the client application, add a service reference to the target service. In the client binding configuration, specify the address of the router service. -
Question 42:
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.
You need to retrieve the debug version of the service JavaScript.
What should you do?
A. In the
B. In the
C. In the script tag, add a debug attribute and set its value to true.
D. In the script tag, append debug to the src attribute. -
Question 43:
A Windows Communication Foundation (WCF) service has the following contract.
[ServiceContract(Namespace="http://contoso.com")] public interface IShipping
{
[OperationContract] string DoWork(int id);
}
This is one of several service contracts hosted by your application. All endpoints use SOAP 1.2 bindings with WS-Addressing 1.0. The System.ServiceModel.MessageLogging trace source in the system.diagnostics configuration section is configured with one listener.
You need to make sure that only the messages that are returned from the DoWork operation are logged.
Which XML segment should you add to the system.serviceModel/diagnostics/messageLogging/filters configuration element?
A. //addr:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse']
B. //soap:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse']
C. //addr:Action[text() = 'http://contoso.com/IShipping/DoWork']
D. //soap:Action[text() = 'http://contoso.com/IShipping/DoWork'] -
Question 44:
A Windows Communication Foundation (WCF) 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 implemented as follows.
(Line numbers are included for reference only.)
01 ServiceHost host = new ServiceHost(typeof(RoutingService));
02 host AddServiceEndpoint(
03 typeof(lSimplexDatagramRouter),
04 new NetTcpBinding0, “net.tcp:/flocalhostlRouter”
05);
06 List
0;t 07 lep.Add(
08 new ServiceEndpoint(
09 ContractDescription.GetContract(
10 typeof(lSimplexDatagramRouter)
11),
12 new NetTcpBinding0,
13 new EndpointAddress|’nettcp://localhost: 8080/Logger”)
14)
15);
16 RoutingConfiguration rc new RoutingConfigurationO;
17 FilterTable.Add(new MatchAilMessageFilterO, lep);
18 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.
What should you do?
A. Change line 03 as follows. typeof(l RequestReplyRouter),
B. Change line 03 as follows. typeof(lDuplexSessionRouter),
C. Change line 10 as follows. typeof(lRequestReplyRouter)
D. Change line 10 as follows. typeof(lDuplexSessionRouter) -
Question 45:
You develop a Windows Communication Foundation (WCF) service that is hosted by using Windows Activation Services (WAS).
You need to configure the service to accept requests that use the TCP/IP protocol.
What should you do? (Each correct answer presents part of the solution. Choose two.)
A. Run the aspnet_regiis executable to enable TCP/IP service activation.
B. In Control Panel, enable the Windows Communication Foundation HTTP Activation feature.
C. In Control Panel, enable the WCF Non-HTTP Activation feature.
D. Run the appcmd executable to enable TCP/IP service activation. -

D. After line 05, add the following line. Replace line 11 with the following line. Throw New FaultException(CX Order)( anOrder, "Divide by zero exception") -
Question 47:
You develop a Window Communication Foundation (WCF) service.

You need to implement the restricted data members.
Which member access modifier should you use?
A. Protected
B. Public
C. Shared
D. Private -
Question 48:
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 =

17)
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.
What should you do?
A. Change line 04 as follows. Get Type(lRequestReplyRouter),
B. Change line 04 as follows Get Type(lDuplexSessionRouter),
C. Change line 12 as follows GetType(lRequestReplyRouter)
D. Change line 12 as follows. Get Type(IDuplexSessionRouter) -
Question 49:
You are developing a Windows Communication Foundation (WCF) service that returns location information for authorized law enforcement agencies. The service contract is as follows.
Users are authenticated and impersonated. The system uses ASP.NET roles. The members of law enforcement are members of the LawEnforcement role.
You need to ensure that only members of the LawEnforcement role can call these methods.
What are two possible ways to achieve this goal (Each correct answer presents a complete solution? Choose two.)
A. Add a PrincipalPermissionAttribute to each method that should be available only to members of law enforcement. Set its SecurityAction to Demand and set the role equal to LawEnforcement.
B. Use the CurrentPrincipal property of the thread. Call the IsInRole method specifying LawEnforcement as a parameter.
C. Create a GenericPrincipal specifying Thread.CurrentPrincipal.Identity as the IIdentityParameter and LawEnforcement as the only value for the Roles parameter.
D. At the beginning of each method, enumerate each ClaimSet in a new WindowsClaimSet. Use the FindClaims method to locate a claim type named Role with a right named LawEnforcement. -
