You are creating a Windows Communication Foundation (WCF) service.
You have the following requirements:
Messages must be sent over TCP.
The service must support transactions.
Messages must be encoded using a binary encoding.
Messages must be secured using Windows stream-based security.
----
You need to implement a custom binding for the service.
In which order should the binding stack be configured?

• A. tcpTransport windowsStreamSecurity transactionFlow binaryMessageEncoding
• B. transactionFlow binaryMessageEncoding windowsStreamSecurity tcpTransport
• C. binaryMessageEncoding transactionFlow tcpTransport windowsStreamSecurity
• D. windowsStreamSecurity tcpTransport binaryMessageEncoding t ransactionFlow

You develop a Windows Communication Foundation (WCF) service.
You name the service MovieService in the Movie namespace. The service is hosted in Microsoft Internet Information Services (IIS).
You copy the assembly containing the service to the bin folder in the virtual directory path.
You need to set up the URI that is mapped to the service.
What should you do?

• A. Add the following code segment to the web.config file.
  <serviceHostingEnvironment>
  <serviceActivations>
  odd relativeAddress=" . /Movie, svc" service="Hovie.MovieService"/>
  </serviceActivations>
  </serviceHostingEnvirorunent>
• B. Add a Movie.svc file in the root of the virtual path with the following line.
  <%8ServiceHost language="C#" Service="MovieService"*>
• C. Add a Movie.svc file in the root of the virtual path with the following line.
  <%8ServiceHost language="C#" Service="MovieService.svc"%>
• D. Add the following code segment to the web.config file.
  <serviceHostingEnvironment>
  <serviceActivations>
  odd relativeAddress="./Movie" service="Movie.MovieService"/>
  </serviceAct ivations>
  </serviceHostingEnvironment>

You are developing a Windows Communication Foundation (WCF) service that contains the following service contract.

You need to ensure that RecordPayments can correctly deserialize into an Employee or a Customer object.
What should you do?

• A. Implement the IExtension<> interface in the Person class.
• B. Implement the IExtensibleDataObject interface in the Person class.
• C. Add the following KnownType attribute to the Employee class and to the Customer class. [KnownType(typeof(Person))]
• D. Add the following KnownType attributes to the Person class. [KnownType(typeof(Employee))] [KnownType(typeof(Customer))]

You are developing a Windows Communication Foundation (WCF) service. You establish that the largest size of valid messages is 8,000 bytes. You notice that many malformed messages are being transmitted.
Detailed information about whether each message is malformed must be logged.
You need to ensure that this information is saved in XML format so that it can be easily analyzed.
What should you add to the service configuration file?

• A. <roessageLogging logEntireMessage="true" logNalformedMessages="false" logMessagesAtServiceLeve1="true" logMessagesAtTransportLevel="true" maxMessagesToLog""1000"/>
• B. <messageLogging logMessagesAtServiceLevel="true" logMessagesAtTransportLevels"true" maxMessagesToLog="1000" maxSizeOfMessageToLog="8000"/>
• C. <message Logging logEntireMessage="true" logHalformedMessages""false" logMessagesAtServiceLevel-"true" logMessagesAtTransportLevel-"true" maxMessagesToLog="1000" maxSizeOfMessageToLog="8000"/>
• D. <messageLogging logEnt ireMessage="true" logHalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTranspoctLevel="true" maxMessagesToLog="1000" maxSizeOfMessageToLog="100000"/>

You are developing a Windows Communication Foundation (WCF) REST service to provide access to a library book catalog. The following code segment defines the service contract. (Line numbers are included for reference only.)

Library patrons want the ability to search the catalog by title.
You need to ensure that the GetBookByTitle method is exposed as a service method.
Which code segment should you insert at line 05?

• A. [WebGet(UriTemplate = "Book/{titleToSearch}")]
• B. [WebGet(UriTemplate = "BookByTitle/{title}")]
• C. [WebGet(UriTemplate = "{titleToSearch}"]
• D. [WebGet(UriTemplate = "Book/{title}")]
