2016 May 70-513 Study Guide Questions:

Q51. You are developing a Windows Communication Foundation (WCF) service that is used to check the status of orders placed by customers. The following code segment is part of your service. (Line numbers are included for reference only.) 

[MISSING]

You need to ensure that the service always listens at net.pipe://SupplyChainServer/Pipe. What should you do? 


A. Option A 

B. Option B 

C. Option C 

D. Option D 

Answer: C 


Q52. 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. 

Answer: D 


Q53. You have an existing Windows Communication Foundation (WCF) service that exposes a service contract over HTTP using explicit binding configuration. 

You need to expose that contract over HTTP and TCP. 

What should you do? 

A. Add a net.tcp base address to the host. 

B. Add an endpoint configured with a netTcpBinding. 

C. Add an endpoint behavior named netTcpBehavior to the existing endpoint. 

D. Add a binding configuration to the existing endpoint named netTcpBinding. 

Answer: B

Q54. A WCF service code is implemented as follows. (Line numbers are included for reference only.) 

01 <ServiceContract()> 02 <ServiceBehavior( 03 InstanceContextMode:=InstanceContextMode.Single)> 04 Public Class CalculatorService 05 06 <OperationContract()> 07 Public Function Calculate(ByVal op1 As Double, 08 ByVal op As String, ByVal op2 As Double) As Double & 24 End Function 25 26 End Class 

You need to decrease the response time of the service. 

What are two possible ways to achieve this goal (Each correct answer presents a complete solution? Choose two.) 

A. Change the service behavior to the following. <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Multiple)> 

B. Change the service behavior to the following. <ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)> 

C. Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel. 

D. Require the clients to use async operations when calling the service. 

Answer: AB 


Q55. A Windows Communication Foundation (WCF) service is self-hosted in a console application. The service implements the ITimeService service interface in the TimeService class. 

You need to configure the service endpoint for HTTP communication. 

How should you define the service and endpoint tags? 

A. Define the service tag as follows. 

<service name=" ITimeService " > 

Define the endpoint tag as follows. 

< endpoint kind =" TimeService " 

address="http://localhost:8080/TimeService" 

binding=" wsHttpBinding " 

contract=" ITimeService"/ > 

B. Define the service tag as follows. 

<service name=" TimeService "> 

Define the endpoint tag as follows. 

< endpoint kind=" TimeService " 

address="http://localhost:8080/TimeService" 

binding=" wsHttpBinding " 

contract=" ITimeService " / > 

C. Define the service tag as follows. 

<service name=" ITimeService "> 

Define the endpoint tag as follows. 

< endpoint name=" TimeService " 

address="http://localhost:8080/TimeService" 

binding=" wsHttpBinding " 

contract=" ITimeService "/ > 

D. Define the service tag as follows. 

<service name=" TimeService "> 

Define the endpoint tag as follows. 

<endpoint address="http://localhost:8080/TimeService" 

binding=" wsHttpBinding " 

contract=" ITimeService "/ > 

Answer: D 


Q56. You develop a Windows Communication Foundation (WCF) service that interacts with Microsoft Message Queuing (MSMQ). 

The service requires sessions. You need to create a custom binding that enables messages sent to the queue to be viewed when you are using a listener tool. 

Which binding elements should you use? 

A. textMessageEncoding and msmqTransport in this order 

B. textMessageEncoding and msmqIntegrationTransport in this order 

C. msmqTransport and textMessageEncoding in this order 

D. msmqIntegrationTransport and textMessageEncoding in this order 

Answer: A

Q57. An existing Windows Communication Foundation (WCF) service uses basicHttpBinding. You are releasing updates to the service and the client application. 

You need to enable the client application to flow transactions to the service. 

What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.) 

A. Change to a custom binding that has the httpTransport, textMessageEndcoding, and transactionFlow binding elements in this order. 

B. Change to a custom binding that has the transactionFlow, textMessageEncoding, and httpTransport binding elements in this order. 

C. Change the binding to use wsHttpBinding. 

D. Change the binding to use basicHttpContextBinding. 

Answer: BC 


Q58. You are developing a Windows Communication Foundation (WCF) service to provide an in-memory cache for many Web applications. The service contract is defined as follows. (Line numbers are included for reference only.) 

01 <ServiceContract()> 02 Public Interface IDataCache 03 

04 . . . 05 End Interface 06 07 08 Public Class DataCache 09 Implements IDataCache 10 

11 . . . 12 End Class 

You need to ensure that all users share the cache. 

Which code segment should you insert at line 07? 

A. <ServiceBehavior (InstanceContextMode : = InstanceContextMode.PerSession)> 

B. <ServiceBehavior(TransactionIsolationLevel:= IsolationLevel.RepeatableRead)> 

C. <ServiceBehavior(TransactionIsolationLevel:= IsolationLevel.ReadCommitted)> 

D. <ServiceBehavior(InstanceContextMode:= InstanceContextMode.Single)> 

Answer: D 


Q59. You are developing a Windows Communication Foundation (WCF) service. 

You need to enable security auditing for all events. 

What should you do? 

A. Set the serviceAuthorizationAuditLevel setting to Success and the messageAuthenticationAuditLevel setting to Success. 

B. Set the messageAuthenticationAuditLevel setting to Success and the auditLogLocation setting to Application. 

C. Set the serviceAuthorizationAuditLevel setting to SuccessAndFailure and the messageAuthenticationAuditLevel setting to SuccessAndFailure. 

D. Set the messageAuthenticationAuditLevel setting to SuccessAndFailure and the auditLogLocation setting to Security. 

Answer: C 


Q60. You are hosting a Windows Communication Foundation (WCF) service at http://www.contoso.com for a law enforcement agency. The agency adds operations to support sending biometric fingerprint data via non-buffered streaming. The service data is not routed between intermediaries. 

The WCF binding you are using by default does not support encryption. 

You need to ensure that fingerprint data is not disclosed when it is passed over the network. 

What should you do? 

A. Use basicHttpBinding with message security to https://www.contoso.com. 

B. Use basicHttpBinding over transport security at https://www.contoso.com. 

C. Use wsHttpBinding over message security at https://www.contoso.com. 

D. Use wsHttpBinding over transport security at http://www.contoso.com.
