You will deploy an Azure Database for MySQL Flexible Server named Server1 in the East US region and must implement business continuity that minimizes downtime if a failover to the paired region is required. Which action should you perform?

Implementing Geo-redundant backup is the correct action because it enables automatic failover to a paired region in the event of a regional outage, minimizing downtime for your Azure Database for MySQL Flexible Server. This option provides the highest level of business continuity for disaster recovery. Creating a read replica is for scaling read operations and can be used for disaster recovery but requires manual intervention for failover, which increases downtime. Storing database files in Azure premium file shares is not a native feature for Azure Database for MySQL and doesn't provide automatic regional failover. Configuring native MySQL replication would require significant manual setup and management, and doesn't offer the integrated, automatic regional failover capabilities of geo-redundant backups.
