Is this statement valid regarding the control and usability of the Debug pages in IdentitylQ?

The statement that the application server must be restarted after reloading the logging file through the Debug-Logging page is incorrect. SailPoint IdentityIQ allows you to reload the logging configuration from the Debug-Logging page without restarting the application server. The Debug-Logging page provides a way to dynamically reload the logging settings, including those in the log4j file, so that changes can take effect immediately without the need for a server restart.

Therefore, the correct answer is B. No.
