What does the administrator need to do to recover quickly after an outage with no backup?

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

Answer: (A)

The ability to recover quickly after an outage when there’s no external backup comes from using the appliance’s revision history. Citrix ADC automatically keeps snapshots of configuration states as you save or commit changes. If the device loses its configuration, you can roll back to a recent, known-good revision and restore the previous setup without rebuilding everything from scratch. This restores the configuration of virtual servers, policies, and objects while keeping downtime to a minimum.

In practice, you pick a recent revision from the revision history and restore it, then commit the change so the device runs with that saved configuration again. After the restore, you’ll want to verify key services, bindings, certificates, and any integrations to ensure everything comes up correctly.

Restarts don’t recover a lost configuration by themselves, and high-availability file synchronization is about keeping two nodes in sync rather than providing a point-in-time recovery if you don’t have a backup. Saving the running configuration to startup helps preserve the current state for the next reboot, but it doesn’t help you recover a previous, working state after an outage.
