With Fast-Start Failover (FSFO), the system automatically detects the failure of the primary Autonomous Container Database and then fails over to a designated standby Autonomous Container Database.

Automatic failover is optional while configuring Autonomous Data Guard. You can enable or disable automatic failover after configuring Autonomous Data Guard.
