Which solution meets this requirement with minimal disruption to the database operations?
Perform an Aurora Multi-AZ deployment.
Deploy Aurora cross-Region read replicas.
Create Amazon Elastic Block Store (Amazon EBS) volume snapshots for Aurora and copy them to another Region.
Deploy Aurora Replicas.
Explanations:
Aurora Multi-AZ deployment provides high availability within the same Region, but it does not fulfill cross-Region disaster recovery requirements.
Aurora cross-Region read replicas allow replication to another Region, ensuring disaster recovery capability with minimal disruption to database operations.
EBS snapshots copied to another Region do not provide continuous replication and would require manual intervention and downtime for disaster recovery.
Aurora Replicas only provide read replicas within the same Region, so they do not meet the cross-Region disaster recovery requirement.
I surmise that the answer is:
Deploy Aurora cross-Region read replicas.
