Answer: Employ AWS Database Migration Service (AWS DMS) to set up a change data capture (CDC) task that continuously replicates changes from the Aurora database to an Amazon S3 bucket in another AWS Region.
The correct answer is C because AWS Database Migration Service (AWS DMS) with a change data capture (CDC) task is a cost-effective solution that meets the requirement of replicating ongoing changes from the Aurora database to an Amazon S3 bucket in another AWS Region. This approach is efficient and incurs lower costs compared to other options like setting up an Aurora global database or frequently creating and transferring snapshots with AWS Lambda. By using AWS DMS, the company can ensure that the data is replicated continuously, thus maintaining the RPO of 1 hour.

A company operates an e-commerce application within a single AWS Region, utilizing a five-node Amazon Aurora MySQL database cluster to manage customer data and recent orders. This database cluster handles a high volume of write transactions daily. To fulfill disaster recovery requirements, the company must replicate this Aurora database data to another AWS Region, adhering to a Recovery Point Objective (RPO) of 1 hour. What is the most cost-effective solution to achieve this data replication?
A
Convert the Aurora database into an Aurora global database and establish a secondary Aurora database in a different AWS Region.
B
Activate the Backtrack feature for the Aurora database and schedule an AWS Lambda function to daily transfer database snapshots to a backup AWS Region.
C
Employ AWS Database Migration Service (AWS DMS) to set up a change data capture (CDC) task that continuously replicates changes from the Aurora database to an Amazon S3 bucket in another AWS Region.
D
Disable automated Aurora backups, configure Aurora backups to occur every hour, designate another AWS Region as the backup destination, and assign the Aurora database as the resource for this backup.
