These records are written to an Amazon RDS MySQL DB. A query must produce the daily average of a data source over the past 30 days. There are twice as many reads as writes. Queries to the collected data are for one source ID at a time.<br \/>\nHow can the Solutions Architect improve the reliability and cost effectiveness of this solution? <br \/><strong><br \/>A.<\/strong> Use Amazon Aurora with MySQL in a Multi-AZ mode. Use four additional read replicas. <br \/><strong>B.<\/strong> Use Amazon DynamoDB with the source ID as the partition key and the timestamp as the sort key. Use a Time to Live (TTL) to delete data after 30 days. <br \/><strong>C.<\/strong> Use Amazon DynamoDB with the source ID as the partition key. Use a different table each day. <br \/><strong>D.<\/strong> Ingest data into Amazon Kinesis using a retention period of 30 days.
