Which action is quickest to recover a Citrix ADC configuration after a misconfiguration when no backup exists?

• A. Restore from revision history
• B. Run Save v/s Running configuration
• C. Restart the Citrix ADC
• D. Rebuild from scratch

Answer: (A)

When a Citrix ADC is misconfigured and there’s no external backup, rolling back to a previous configuration snapshot stored in the appliance’s revision history is the fastest way to recover. Revision history keeps versions of the configuration as you save changes, so you can select a known-good revision and restore it. This replaces the current running config with that earlier state in one step, minimizing downtime and avoiding the need to manually undo edits. After restoring, save the configuration to startup to make the recovered state persist across reboots. Restarting would simply reboot with the existing startup configuration, which may still contain the misconfiguration, and rebuilding from scratch is far more time-consuming.
