DEA-C01 Data Store Management Practice Question
A company is using Amazon RDS for MySQL and wants to automate backups for point-in-time recovery. Which TWO actions should be taken? (Choose TWO.)
⚠ Common exam trap
Candidates often confuse Multi-AZ deployment (which provides failover) with backup automation, or assume AWS Backup is required for automated backups, when in fact RDS native automated backups are sufficient and the primary method for PITR.
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.
Enabling automated backups in Amazon RDS for MySQL allows point-in-time recovery (PITR) to any second within the retention period. Option C is correct because setting the backup retention period to the desired number of days (1–35 days) defines how far back you can perform PITR, and it must be explicitly configured to enable automated backups.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable automated backups with a retention period.
Why this is correct
Automated backups provide point-in-time recovery and are enabled by default.
- ✗
Use AWS Backup to schedule backups.
Why it's wrong here
AWS Backup is an alternative but not necessary; RDS native automated backups already exist.
- ✓
Set the backup retention period to the desired number of days.
Why this is correct
Retention period determines how long automated backups are kept.
- ✗
Enable Multi-AZ deployment.
Why it's wrong here
Multi-AZ provides failover, not backups.
- ✗
Take manual snapshots daily.
Why it's wrong here
Manual snapshots are not automated; they require manual intervention.
