AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company is looking to design a disaster recovery strategy for their critical workloads which are hosted on Amazon EC2 instances. They want to ensure they have point-in-time recovery snapshots and the ability to quickly restore these snapshots in another region in case the primary region fails. What is the BEST approach to meet these requirements?
Create a Lambda function to manually trigger snapshots of EC2 instances periodically and copy the snapshots to another region.
Use Amazon Data Lifecycle Manager to automate the creation of backups and replicated snapshots to another region.
Rely on Amazon EC2 instance store-backed volumes for automatic replication across multiple regions.
Use AWS Backup to create on-demand backups and replicate them to the same region for higher availability.
The best approach is to use Amazon Data Lifecycle Manager to automate the creation of backups and then use cross-region snapshot copy features for replicating snapshots to another region. This meets the company's requirements for point-in-time recovery and quick restoration in a secondary region without any manual intervention, thus aligning with AWS best practices for disaster recovery planning.
