DBS-C01 Deployment and Migration Practice Question
Which TWO actions are recommended when deploying an Amazon RDS for MySQL instance in a production environment to ensure high availability and durability? (Choose two.)
⚠ Common exam trap
A common mix-up: candidates confuse monitoring and performance tools (Enhanced Monitoring, Performance Insights) with high availability or durability features, or they mistakenly think deletion protection provides data durability, when in fact only automated backups and Multi-AZ deployment directly address these concerns.
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 at least 7 days
Automated backups with a retention period of at least 7 days enable point-in-time recovery (PITR) within that window, which is critical for restoring a database to a specific second in the event of a failure or data corruption. This ensures durability by allowing you to recover from logical errors or accidental deletions, not just hardware failures. Option E is correct because Multi-AZ deployment automatically provisions and maintains a synchronous standby replica in a different Availability Zone, providing automatic failover for high availability without manual intervention.
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 Enhanced Monitoring
Why it's wrong here
Enhanced Monitoring provides metrics at the OS level, not high availability.
- ✓
Enable automated backups with a retention period of at least 7 days
Why this is correct
Automated backups allow point-in-time recovery within the retention period.
- ✗
Enable Performance Insights
Why it's wrong here
Performance Insights helps with performance tuning, not high availability.
- ✗
Enable deletion protection
Why it's wrong here
Deletion protection prevents accidental deletion, not high availability.
- ✓
Enable Multi-AZ deployment
Why this is correct
Multi-AZ provides automatic failover to a standby in a different AZ.
