Topic 1 Question 588
An ecommerce company wants a disaster recovery solution for its Amazon RDS DB instances that run Microsoft SQL Server Enterprise Edition. The company's current recovery point objective (RPO) and recovery time objective (RTO) are 24 hours.
Which solution will meet these requirements MOST cost-effectively?
Create a cross-Region read replica and promote the read replica to the primary instance.
Use AWS Database Migration Service (AWS DMS) to create RDS cross-Region replication.
Use cross-Region replication every 24 hours to copy native backups to an Amazon S3 bucket.
Copy automatic snapshots to another Region every 24 hours.

Snapshots are always a cost-efficience way to have a DR plan.

This is the most cost-effective solution because it does not require any additional AWS services. Amazon RDS automatically creates snapshots of your DB instances every hour. You can copy these snapshots to another Region every 24 hours to meet your RPO and RTO requirements.
The other solutions are more expensive because they require additional AWS services. For example, AWS DMS is a more expensive service than AWS RDS.
