The correct answer is to create manual snapshots at regular intervals and retain them for 7 years. This works because manual snapshots are stored in Amazon S3 and persist indefinitely until you explicitly delete them, unlike automated backups which are capped at a maximum retention period of 35 days. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding of the fundamental difference between automated and manual snapshot lifecycles—a common trap is assuming you can extend automated backup retention beyond 35 days or that exporting to S3 replaces the need for manual snapshots, but exports are for data portability, not backup retention. To retain RDS backups for 7 years compliance, you must schedule regular manual snapshots via AWS Backup or a custom script, as they are the only native mechanism for long-term retention. Memory tip: think of automated backups as a short-term lease (35 days max) and manual snapshots as a permanent deed—you hold them until you choose to let go.
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A database administrator needs to retain backups of an Amazon RDS for PostgreSQL DB instance for 7 years to meet compliance requirements. The automated backup retention period is limited to 35 days. Which solution should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create manual snapshots at regular intervals and retain them for 7 years.
Manual snapshots are retained indefinitely until deleted. Automated backups have a max retention of 35 days. Exporting to S3 is an option but not directly a backup retention method; you can export snapshots to S3, but manual snapshots are the standard way to retain backups long-term. EC2 instance backups are not applicable.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Export the automated backups to Amazon S3 and apply an S3 lifecycle policy.
Why it's wrong here
Automated backups cannot be directly exported; you can export snapshots, but manual snapshots are the primary method.
✓
Create manual snapshots at regular intervals and retain them for 7 years.
Why this is correct
Manual snapshots are retained until deleted, suitable for long-term retention.

✗
Increase the automated backup retention period to 7 years.
Why it's wrong here
Automated backup retention max is 35 days.
✗
Use an AWS Lambda function to copy automated backups to an EC2 instance.
Why it's wrong here
This is not a supported or efficient method.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
