A file named Util.asmx contains the following code segment.

(Line numbers are included for reference only.)
01 <%@ WebService Language=”C#” class=”Exam.Util” %>
02 namespace Exam {
03 public class Util {
04 public string GetData() {
05 return “data”;
06 }
07 }
08 }

You need to expose the GetData method through a Web service.

What should you do?

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.)

You are an enterprise application developer. You create a component that generates medical documents. Your component is used by multiple document management systems. Users generate documents throughout the entire day and most documents are generated during business hours. You notice that user load is increasing and performance is degrading. You need to identify sections of code on which to focus performance tuning efforts. Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)
