DBS-C01 Deployment and Migration Practice Question
A company is planning to deploy a new Amazon RDS for Oracle database in a Multi-AZ configuration. The database must be highly available and fault-tolerant. Which THREE actions should the company take to meet these requirements? (Choose three.)
⚠ Common exam trap
Watch out — candidates often confuse read replicas with Multi-AZ standby replicas: read replicas are for read scaling and do not provide automatic failover, whereas Multi-AZ standby replicas are synchronous and enable automatic failover for high availability.
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 Multi-AZ deployment
Enabling Multi-AZ deployment for Amazon RDS for Oracle automatically provisions and maintains a synchronous standby replica in a different Availability Zone. This provides automatic failover in the event of an AZ outage or primary instance failure, ensuring high availability and fault tolerance 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.
- ✗
Take manual snapshots daily
Why it's wrong here
Manual snapshots are for long-term retention, not high availability.
- ✗
Create a read replica in a different Availability Zone
Why it's wrong here
Read replicas do not provide automatic failover.
- ✓
Enable Multi-AZ deployment
Why this is correct
Multi-AZ provides automatic failover.
- ✓
Enable automated backups with a retention period of 35 days
