I guess the question here is wrong.
Which AWS database service is best suited for read-intensive workloads?
-> Amazon DynamoDB is correct
-> Amazon Aurora is correct
The AI explains why DynamoDB is not correct:
"The question’s reference explanation highlights “up to 15 read replicas,” which points to an RDS-style relational engine. DynamoDB does not use the same read-replica model (it scales via partitioning, global tables, and optional caching), so it’s not the answer the exam item expects."
No, the question does not reference "up to 15 read replicas". If so Aurora is correct answer so the question seems to be missing the hint to 15 read replica. "Which AWS database service is best suited for read-intensive workloads?" Frustrating.

Thanks for pointing out. You're right. Both Aurora and DynamoDB can be excellent for read-heavy workloads. Which one is "best" depends on the workload’s characteristics. To eliminate the ambiguity, we've updated the question that require requires SQL/ACID transactions.
Thank you for your feedback. It really help us keep improving the quality of questions that shared with other.
