Configure an Amazon RDS event subscription to send a notification to an AmazonSNS topic to which the Lambda function is subscribed.
B. Configure both Aurora Replicas to have the same instance class as the primary DB instance.
ImplementAurora PostgreSQL DB cluster cache management. Set the failover priority to tier-0 for the primary DBinstance and to tier-1 for the replicas.
C. Configure one Aurora Replica to have the same instance class as the primary DB instance.
