Question 610
A deployed environment still does not meet the original requirement: An Aurora-backed API has too many queries on the writer and wants to distribute read-only reporting traffic. Which failure mechanism should the team correct?
Explanation
Correct Answer
This is the technical design error aligned with the unmet requirement. Aurora reader endpoints balance connections to read replicas for read workloads. The appropriate correction is: Send eligible reads through the Aurora reader endpoint and provision suitable replica capacity. The control should then be tested by verifying that Read latency and writer CPU improve under reporting load without routing writes to read replicas.
Incorrect Answers
Every static asset fetch goes to a distant origin instead of the edge cache. The stated evidence instead indicates: Every reporting query was sent to the cluster writer endpoint despite available readers.
No event archive exists to replay notifications that failed during downstream processing. The stated evidence instead indicates: Every reporting query was sent to the cluster writer endpoint despite available readers.
Unbounded request bursts overload backends because no gateway rate protection is configured. The stated evidence instead indicates: Every reporting query was sent to the cluster writer endpoint despite available readers.
