AWS Certified Solutions Architect – Associate (SAA-C03) — Question 180

A company’s infrastructure consists of Amazon EC2 instances and an Amazon RDS DB instance in a single AWS Region. The company wants to back up its data in a separate Region.

Which solution will meet these requirements with the LEAST operational overhead?

Answer options

• A. Use AWS Backup to copy EC2 backups and RDS backups to the separate Region.
• B. Use Amazon Data Lifecycle Manager (Amazon DLM) to copy EC2 backups and RDS backups to the separate Region.
• C. Create Amazon Machine Images (AMIs) of the EC2 instances. Copy the AMIs to the separate Region. Create a read replica for the RDS DB instance in the separate Region.
• D. Create Amazon Elastic Block Store (Amazon EBS) snapshots. Copy the EBS snapshots to the separate Region. Create RDS snapshots. Export the RDS snapshots to Amazon S3. Configure S3 Cross-Region Replication (CRR) to the separate Region.

Correct answer: A

Explanation

The correct answer is A because AWS Backup provides a centralized way to manage backups with the least overhead. Options B, C, and D involve more complex processes or additional steps that require more management and maintenance, making them less efficient compared to using AWS Backup.
