What should you do to alter where Trace information is written?

1. Add a new TraceListener

2. Change the TraceSource name

3. Remove all TraceListeners

4. Create a new TraceSource

The correct answer is: Add a new TraceListener

To alter where Trace information is written, adding a new TraceListener is the appropriate action. A TraceListener is responsible for receiving the trace output and directing it to a specific location, such as a console window, a file, or an event log. By creating and adding a new TraceListener, you can specify the exact destination for the trace output, which allows for greater flexibility and control over how and where trace information is logged. Utilizing the TraceListener class makes it possible to customize the output format and location according to your application's needs. This is especially valuable for debugging and logging during development, or for monitoring in production environments. While changing the TraceSource name or creating a new TraceSource could theoretically affect where the traces are monitored or captured, those actions do not directly alter the output destination itself. Removing all TraceListeners would stop any tracing from being collected altogether, which is contrary to the goal of altering the output destination. Therefore, adding a new TraceListener is the direct method to control and modify the tracing output in a meaningful way.
