AWS Certified Database – Specialty — Question 28

A company has an Amazon RDS Multi-AZ DB instances that is 200 GB in size with an RPO of 6 hours. To meet the company's disaster recovery policies, the database backup needs to be copied into another Region. The company requires the solution to be cost-effective and operationally efficient.
What should a Database Specialist do to copy the database backup into a different Region?

Answer options

• A. Use Amazon RDS automated snapshots and use AWS Lambda to copy the snapshot into another Region
• B. Use Amazon RDS automated snapshots every 6 hours and use Amazon S3 cross-Region replication to copy the snapshot into another Region
• C. Create an AWS Lambda function to take an Amazon RDS snapshot every 6 hours and use a second Lambda function to copy the snapshot into another Region
• D. Create a cross-Region read replica for Amazon RDS in another Region and take an automated snapshot of the read replica

Correct answer: C

Explanation

Option C is correct because it directly addresses the requirement to create a snapshot every 6 hours and provides a mechanism to transfer it to another Region using Lambda functions. Option A does not specify the frequency of snapshots, while Option B involves S3 replication, which is not the optimal approach for RDS snapshots. Option D introduces unnecessary complexity by creating a read replica instead of focusing on snapshot management.
