The Lambda function is designed to process these notifications and store their contents in an Amazon RDS Multi-AZ DB instance. During a test, the DB instance was inadvertently shut down by a database administrator, resulting in the loss of several SNS notification messages that were sent during the downtime. To prevent such data loss in the future, which two solutions should the DevOps engineer implement?
