How would you handle a practical scenario involving High Availability in SQL Server?

For a practical scenario involving High Availability, I would first clarify the business goal, scale, constraints, and the failure or quality attribute being tested. SQL Server high availability uses technologies such as Always On availability groups and failover clustering to reduce downtime. The scenario centers on for a critical database requiring local automatic failover and regional disaster recovery, describe a practical availability group topology and operational plan. I would then compare the main alternatives and tradeoffs, identify likely failure modes, and explain how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
