Learn Java Logging – Module 2 Lesson 3 – Quiz

In Log4j 2, what is the primary responsibility of a Layout?

If we define a logger like this:

<Logger name=”LoggerWithFileAppender” level=”INFO” additivity=”false”>

    <AppenderRef ref=”LogFile”/>

</Logger>

What does additivity=”false” ensure?

Which configuration correctly sets up a RollingFile appender that rolls on size?

 Let’s say we added the JSONTemplateLayout to a File appender, but get a “plugin not found” error. What did we most likely forget?

Given this pattern in a console appender:

<PatternLayout pattern=”%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c [%X{userName} – %mdc{userId}] – %m%n”/>

What will populate the userName and userId placeholders?
