If configuration changes cause an outage and there is no backup, what is the fastest recovery approach?

• A. Restart the Citrix ADC.
• B. Run saved versus running configuration.
• C. Run HA file synchronization.
• D. Restore from the revision history.

Answer: (D)

Revision history stores snapshots of every configuration change on the Citrix ADC. When a recent change causes an outage and there’s no backup, reverting to a previous revision returns the device to a known-good state quickly. This approach is fastest because it uses an in-device, validated configuration without needing external backups or rebuilding settings from scratch—just select an earlier revision and apply it, and traffic can resume with the prior working configuration. Restarting the appliance doesn’t inherently revert to a previous state, and options that rely on comparing or syncing configurations depend on conditions that may not be present here. Restoring from revision history directly provides a fast, reliable path back to service.
