An auto-failover group is the most appropriate disaster recovery solution for the back-end tier of the payment processing system. Auto-failover groups manage the replication and failover of a group of databases to another region, ensuring that the system remains available without any administrative intervention if a data center fails. This feature simplifies the deployment and management of geo-replicated databases and ensures minimal downtime, which is crucial for a payment processing system.
The question is targeting thie requirement: If a data center fails, ensure that the payment processing system remains available without any administrative intervention. The middle-tier and the web front end must continue to operate without any additional configurations. Azure Site Recovery It's used for server recovery and has time outage Always On Failover Cluster Instances this is part of SQL server Always On, not suitable for Azure SQL database or Azure SQl Managed Instance geo-redundant database I guess this means Active geo-replication faeture. This needs manual intervention to execute failover. Correct Answer: Auto-failover Group It allows you to manage the replication and failover of a group of databases to another region. Also it allows you to automatically recover multiple related databases using a user-defined policy
