In which configuration scope would you place the AsyncLogger entry to enable dynamic package and level logging at startup?

• A. <Configuration><Appenders></Appenders></Configuration>
• B. <Loggers><Appenders></Appenders></Loggers>
• C. <Loggers><Configuration></Configuration></Loggers>
• D. <Configuration><Loggers></Loggers></Configuration>

Answer: (D)

Log4j2 configuration is organized with a root element that contains separate sections for loggers and appenders. Logger definitions, including AsyncLogger entries, must live under the block so they can specify package-based names and log levels, while Appenders live in their own section. Placing the AsyncLogger inside ensures the dynamic, per-package logging settings are loaded when the startup configuration is parsed. Nesting logger definitions inside Appenders or placing a element inside would be invalid and ignored by the parser. Therefore the correct structure is to place AsyncLogger within the section under the root .
