Answer: A, C

Explanation:

The tWarn component is used to trigger a warning message that can be caught by the tLogCatcher component for an exhaustive log. The tLogCatcher component is a component that collects the log data generated by the tWarn, tDie, and Java Exception components and passes it on to the output defined. The tWarn component can be used alongside a tLogCatcher component in order for the log data collected to be encapsulated and passed on to the output defined. The tWarn component can also be used independently of the tLogCatcher component, but in that case, the warning message will only be displayed in the console. The tWarn component is not used only in conjunction with the log4j feature, nor only in conjunction with a tLogCatcher component. The log4j feature is a logging framework that allows you to customize the logging level, format, and destination of your log messages. You can enable or disable the log4j feature in Talend Studio by checking or unchecking the Use log4j option in the Preferences menu. The tLogCatcher component can catch log data from other components besides the tWarn component, such as the tDie and Java Exception components.
