問題2

You are developing a client application that uses the following code to consume a Windows Communication Foundation (WCF) service. (Line numbers are included for reference only.)
01 BasicHttpBinding myBinding = new BasicHttpBinding(); 02 EndpointAddress myEndpointAddress = new EndpointAddress( "http://contoso.com/TaxService.svc");
04 ITaxService client = channelFactory.CreateChannel();
05 string data = client.GetData(1);
You need to consume the service.
Which code segment should you insert at line 03?

A. var channelFactory = new ChannelFactory<ITaxService>( myBinding, myEndpointAddress);

B. var channelFactory = new ChannelFactory<ITaxService>();

C. var channelFactory = new ChannelFactory<ITaxService>( "http://contoso.com/TaxService.svc");

D. var channelFactory = new ChannelFactory<ITaxService>( myBinding);

正確答案: A

問題3

You are configuring services to be discoverable. The services must be discoverable without relying on a central server. Client applications that consume the services are on a network segment that is separate from the network segment that the services are located on.
A firewall blocks all TCP ports between the two network segments, but allows other protocols to pass through.
You need to ensure that the client applications can discover the services.
What should you do?

A. Use managed discovery mode over UDP.

B. Use managed discovery mode over HTTP.

C. Use ad-hoc discovery mode over HTTP.

D. Use ad-hoc discovery mode over UDP.

正確答案: D

問題4

You are modifying a Windows Communication Foundation (WCF) service that allows customers to update financial data. The service currently requires a transaction from the client application and is working correctly. The service contract is defined as follows. (Line numbers are included for reference only.)

The service must be modified so that client applications do not need to initiate a transaction when calling the operation. The service must use the client application's transaction if one is available. Otherwise it must use its own transaction.
You need to ensure that the service operation is always executed within a transaction.
What should you do?

A. Replace line 05 with the following code. <TransactionFlow( TransactionFlowOption.Allowed) >

B. Replace line 05 with the following code. <TransactionFlow( TransactionFlowOption.NotAliowed)>

C. Replace line 13 with the following code. <OperatlonBehavior( TransaetionScopeRequired:"False, TransactionAutoComplete:"False)>

D. Replace line 13 with the following code. <OperationBehavior( TransactionScopeRequired:"False, TransactionAutoComplete:-True)>

正確答案: D

問題5

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. In Control Panel, enable the WCF Non-HTTP Activation feature.

B. In Control Panel, enable the Windows Communication Foundation HTTP Activation feature.

C. Run the aspnet_regiis executable to enable TCP/IP service activation.

D. Run the appcmd executable to enable TCP/IP service activation.

正確答案: B,D

問題6

You want to debug the Windows Communication Foundation (WCF) client and server interaction through message and application tracing.
You need to correlate traces generated on the client and the server.
Which XML segment should you add to the system. diagnostics configuration element in the client and server application configuration file?

A. <sources>
<source names"System. ServiceModel" switchValues'VerboseActivityTracing"> <listeners>
<add namee"ServiceModelTraceListener" /> </listeners> </source>
</sources>

B. <sources> <source names" System ServiceModel. MessageLogging"
switchValuee"Verbose"> <listeners>
<add namez"ServiceModelTraceListener" /> <Listeners>
</source> </sources>

C. <sources> <source propagate Activitye'true" namee"System Service Model"
switchValues'Warning, ActivityTracing'> <listeners
<add namez"ServiceModelTraceListener" /> </listeners>
</source> </sources>

D. <sources>
<source names"System. ServiceModeiMessageLogging" propagateActivitye'true" switch Values' Warning, ActivityTracing'5 <listeners> <add name="ServiceModelTraceListener" I> </listeners> </source> </sources>

正確答案: C

問題7

A Windows Communication Formation (WCF) client and service share the following service contract interface
<ServiceContractO>
Public Interface IContosoService <OperationContractO>
Sub SasePerson(BWal person As Person) End Interface They also use the following
binding.
Dim binding As NetTcpBinding = New NetTcpBinding With {TransactionFlow = True) The
client cals the service with the (following code using (mransactionScope ts = new
TransactionScope(TransactionScopeOption
Required))
{
IContosoService client = factoryCreateChannelO;
client SavePerson(person);
Consde. WriteLine(
Transaction. CurreriTransactioninformation
DistnbutedldentifierX
ts CorrpleteO;
)
The service has the following impementation for SavePerson
Public Sub SavePerson(ByVal person As Perwn) - implements IContosoService
SavePerson person Save()
ConsdeWriteLine(Transaction .Current Transactionlnformaiona
Distributedldentifier)
End Sit
The distributed identifiers do not match on the client and the server.
You need to ensure that the client and server enlist in the same distributed transaction
What should you do?

A. Add the following attribute to the SavePerson operation on KOontosoService.
<TransactionFlow(TransactionFbwOption Allowed)>
Add the following attribute to the implementation of SavePeson.
eOperationBehavior(TransactionSc
opeRequired True)>

B. Add the following attribute to the SavePerson operation on KContosoService.
<OperationBehavior(TransachonSc opeRequired True)>
Add the following attribute to the implementation of SavePeson.
<TransactionFlow(TransactionFbwOption
Allowed)>

C. Add the following attributes to the SavePerson operation on IContosoSewvice
<TransactionFlow(TransactionFbwOption Maidatory)>
eOperationBehavior(TransactionSc opeRequired zTrue)>

D. Add the following attributes to the SavePerson operation on lContosoService
eOperationBehavior(TransactionSc opeRequired =True)>
<TransactionFlow(TransactionFbwOption Madatory)>

正確答案: A

問題8

The endpoint of a Windows Communication Foundation (WCF) service uses basicHttpBinding for its binding. Your company's policies have changed to require that messages not be sent in clear text.
