DEA-C01 Data Store Management Practice Question

A company stores financial data in Amazon RDS for MySQL. They need to retain backups for 7 years to meet compliance. Which backup strategy meets this requirement?

⚠ Common exam trap

Many exam-takers assume automated backups can be configured for long retention periods, but AWS enforces a hard 35-day limit, making AWS Backup the only viable option for multi-year retention.

Correct answer & explanation

✓

Use the AWS Backup service with a 7-year retention policy

AWS Backup is the correct service for long-term retention of RDS snapshots beyond the 35-day limit of automated backups. It allows you to create backup plans with retention policies up to 100 years, making it suitable for the 7-year compliance requirement. Manual snapshots can also be retained indefinitely, but AWS Backup provides centralized management and lifecycle policies.
