Question 223 of 1,711
DEA-C01 Data Store Management Practice Question
A company uses Amazon RDS for PostgreSQL. The data engineer needs to ensure that the database is automatically backed up and that backups are retained for 35 days. What is the simplest way to achieve this?
⚠ Common exam trap
The trap here is that candidates may overcomplicate the solution by choosing AWS Backup (Option A) or manual scripting (Option C), not realizing that RDS native automated backups already provide the simplest, fully managed way to achieve the required retention period.
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
✓
Enable automated backups with a retention period of 35 days in the RDS instance configuration.
Amazon RDS for PostgreSQL allows you to enable automated backups directly in the instance configuration. By setting the backup retention period to 35 days, RDS automatically performs daily snapshots and retains transaction logs for point-in-time recovery within that window. This is the simplest method because it requires no external services or custom scripting.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Backup to schedule daily backups with a 35-day retention.
Why it's wrong here
AWS Backup is an additional service that adds complexity; RDS automated backups already meet the requirement.
- ✓
Enable automated backups with a retention period of 35 days in the RDS instance configuration.
Why this is correct
RDS automated backups run daily and retain backups for the specified period, up to 35 days.
- ✗
Create a manual snapshot every day and delete them after 35 days using a script.
Why it's wrong here
Manual snapshots require scripting and do not provide automatic daily backups without additional effort.
- ✗
Enable automatic export of transaction logs to Amazon S3 and use S3 lifecycle policies.
Why it's wrong here
Exporting logs to S3 is for point-in-time recovery, not a simple backup solution.
