Citrix Deploy and Manager Citrix ADC13 with Citrix Gateway 1Y0-231 Practice Test

When there is no backup, the best way to undo a misconfiguration on Citrix ADC is to restore a previous configuration from revision history. Revision history stores past configurations as separate revisions, so you can roll back to a known-good state from before the changes were made. By selecting a prior revision and restoring it, the running configuration is replaced with the configuration that existed at that earlier point, effectively undoing the faulty changes without needing an external backup. After restoring, you can save the configuration if you want that good state to persist after a reboot.

Restarting the device won’t revert the changes; it just reboots and leaves the running configuration as-is. HA file synchronization is intended to keep two nodes aligned and is not a method to undo a misconfiguration unless the other node has the desired configuration to synchronize, which isn’t a guaranteed fix. Saving the running configuration to startup would simply preserve the current (mis)configuration for the next boot, not recover a correct state.
