- A
Enable manual snapshots daily and retain for 35 days.
Why wrong: Manual snapshots require manual effort and do not support point-in-time recovery.
- B
Set the backup retention period to 35 days and enable automatic backups.
Automated backups allow point-in-time recovery within the retention period.
- C
Set the backup retention period to 7 days and create daily manual snapshots.
Why wrong: 7 days is insufficient and manual snapshots lack point-in-time recovery.
- D
Disable automated backups and rely on Multi-AZ for recovery.
Why wrong: Multi-AZ provides failover, not backups.

DEA-C01 Data Store Management Practice Question
This DEA-C01 practice question tests your understanding of data store management. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company is using Amazon RDS for MySQL and needs to automate backups with a retention period of 35 days. They also want to be able to restore to any point within the retention period. Which configuration should be used?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the backup retention period to 35 days and enable automatic backups.
Amazon RDS for MySQL supports automated backups with a configurable retention period of up to 35 days. By setting the backup retention period to 35 days and enabling automatic backups, RDS automatically performs daily snapshots and transaction log backups, enabling point-in-time recovery (PITR) to any second within the retention window. This meets the requirement for both a 35-day retention and full PITR capability without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Set the backup retention period to 7 days and create daily manual snapshots.
Why it's wrong here

Why it's wrong here
Multi-AZ provides failover, not backups.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse manual snapshots (which are retained indefinitely but do not support PITR) with automated backups (which support PITR but have a maximum retention of 35 days), leading them to choose Option A or C, thinking manual snapshots can extend the PITR window.
Detailed technical explanation
How to think about this question
Automated backups in RDS for MySQL include daily automated snapshots and transaction log backups (binary logs) captured every 5 minutes, enabling PITR to any second within the retention period. The backup retention period can be set from 0 to 35 days; setting it to 35 days ensures that both the daily snapshots and the transaction logs are retained for the full 35 days, allowing restoration to any point within that window. Under the hood, RDS stores these backups in Amazon S3, and the transaction logs are purged only after the retention period expires, which is critical for compliance scenarios requiring long-term recovery granularity.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
