True or False: It is advised to modify default config files in Splunk.

Modifying default configuration files in Splunk is generally not advised because it can lead to a variety of issues, especially when upgrading the software. When Splunk is upgraded, any changes made to the default configuration files might be overwritten, leading to potential loss of customization and inconsistent behavior of the system.

Instead of modifying default configuration files, it's recommended to create new configuration files or to override default settings in local configuration files. This ensures that custom configurations are preserved across upgrades and maintains the integrity and stability of the Splunk installation. By keeping default configurations intact, you also facilitate troubleshooting and ensure that you can always revert to original settings if necessary.

In some cases, creating a custom configuration can provide a clear separation of default behavior and custom tweaks, making it easier for administrators to manage and document changes.
