Question: You work as a Web Developer at Company.com. You make use of Microsoft ASP.NET 3.5 to create a Web application. A page in the application holds the code that calls the Write and Warn methods of the TraceContext class. The code also adds an instance of EventLogTraceListener to the System.Diagnostics.Trace.Listeners collection. You need to ensure that the Write and Warn methods of the TraceContext class will write ASP.NET trace messages to the event log automatically. You have to configure the Web application to accomplish this. What should you do?

1. In the the Web.config file, you should add the configuration:
   <trace enabled=”true” pageOutput=”true” localOnly=”true” writeToDiagnosticsTrace=”true”/>
2. On the page, you should add the next Page directive:
   <%@ Page Trace=”true” Debug=”false” %>
3. In the the Web.config file, you should add the configuration:
   <trace enabled=”true” pageOutput=”false” localOnly=”true” writeToDiagnosticsTrace=”true”/>
4. On the page, you should add the next Page directive:
   <%@ Page Trace=”true” Debug=”true” %>

Correct Answer: 3

Question: You work as a Web Developer at Company.com. You are in the process of creating a Web application that uses Microsoft ASP.NET 3.5. The code below is present in the application:

public class Account
{
public double Balance { get; set; }
public void Deposit(double amount)
{
Balance += amount;
}
public void Withdraw(double amount)
{
System.Diagnostics.Trace.WriteLineIf(amount > Balance, "Potential Overdraft.");
if (amount <= Balance)
{
Balance -= amount;
}
}
} 

The above code will write a trace message when there is a potential for an overdraft. You need to configure the Web.config file in order to write the trace message to the trace viewer tool (Trace.axd). Identify the configurations that should be used? (Choose all that apply)

1. You should use the following:
   <trace enabled=”true”/>
2. You should use the following:
   <system.diagnostics>
   <trace>
   <listeners>
   <add name=”WebPageTraceListener” type=”System.Web.WebPageTraceListener, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”/>
   </listeners>
   </trace>
   </system.diagnostics>
3. You should use the following:
   <trace enabled=”false” writeToDiagnosticsTrace=”true”/>
4. You should use the following:
   <trace enabled=”false” writeToDiagnosticsTrace=”true” pageOutput=”false”/>
5. You should use the following:
   <system.diagnostics>
   <switches>
   <add name=”PageOutput” value=”Trace.axd”/>
   </switches>
   </system.diagnostics>
