You are creating a Web service.
You need to add an operation that can be called without returning a message to the caller.
Which code should you use?

A SOAP message has the following body.

<soap:Body>
<tns:Greeting>
<Person href="#id1" />
</tns:Greeting>
<tns:User id="id1" xsi:type="tns:User">
<GivenName xsi:type="xsd:string">givenname</GivenName>
<SurName xsi:type="xsd:string">surname</SurName>
</tns:User>
</soap:Body>

You need to configure the Greeting method to accept the SOAP message.

Which code segment should you use?

A Windows-based application sends messages to the TestMessageQueue queue.

An acknowledgement message must be sent to the TestMessageQueueAdmin queue when:
The original message is retrieved from TestMessageQueue.
The message has not been retrieved from TestMessageQueue after a specified time period.

The following code is used to send a message to the TestMessageQueue queue.

(Line numbers are included for reference only.)
01 MessageQueue mq = new MessageQueue(".TestMessageQueue");
02 MessageQueue mqAdmin = new MessageQueue(".TestMessageQueueAdmin");
03 Message m = new Message(messageBody);
04 m.AcknowledgeType = AcknowledgeTypes.PositiveReceive;
05 mq.Send(m);

You need to ensure that an acknowledgement message is sent to the TestMessageQueueAdmin queue as required.
Which two actions should you perform?
(Each correct answer presents part of the solution. Choose two.)

You use Microsoft Visual Studio 2005 to create a custom Web service discovery system that contains Disco files for your Web services.
You need to have the Disco file for each of your Web services for auditing purposes.
What are two possible ways to achieve this goal?

(Each correct answer presents a complete solution. Choose two.)

You create a Web service that exposes a Web method named CalculateStatistics.

The response returned by the CalculateStatistics method for each set of input parameters changes every 60 seconds.
You need to ensure that all requests to the CalculateStatistics method that have the same set of input parameters, and that occur within a 60-second time period, calculate the statistics only once.

Which code segment should you use?

You are writing an application that handles the batch processing of user accounts.
The application assigns network identities for users by calling the following Web service method.

[WebMethod]
public string GetNetworkID(string name)
{ …}

The application calls the Web
service using the following code.

(Line numbers are included for reference only.)
01 void ProcessPeople(List<Person> people) {
02 PersonService serviceProxy = new PersonService();
03 serviceProxy.GetNetworkIDCompleted += new
04 GetNetworkIDCompletedEventHandler(GetNetworkIDCompleted);
05 for (int i = 0; i < people.Count;i++) {
06 …
07 }
08 }
09
10 void GetNetworkIDCompleted(object sender,
11 GetNetworkIDCompletedEventArgs e){
12 Person p = null;
13 …
14 p.NetworkID = e.Result;
15 ProcessPerson(p);
16 }

You need to ensure that the application can use the data supplied by the Web service to update each Person instance. Which two actions should you perform? (Each correct answer
presents part of the solution. Choose two.)
