Using Splunk Web to modify config settings for a shared object, a revised config file...

 The correct answer is A because using Splunk Web to modify config settings for a shared object, a revised config file with those changes is placed in the $SPLUNK_HOME/etc/apps/myApp/local directory. The local directory is where Splunk stores the configuration files that are modified by the user, either through Splunk Web or by editing the files directly. The local directory has the highest priority in the configuration layering scheme, which means it overrides the settings in the default directory. The other options are incorrect because they either use the wrong directory or the wrong priority. You can find more information about the configuration files and the configuration layering scheme in the Splunk Developer Guide.
