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
✓
Amazon RDS Multi-AZ
Amazon RDS Multi-AZ provides high availability with automated failover. Amazon Aurora is also fully managed and provides high availability, but the question asks for a relational database service; both RDS and Aurora are valid, but RDS Multi-AZ is a direct fit for the requirement. DynamoDB is NoSQL. RDS Single-AZ does not provide failover. ElastiCache is for caching.
