AWS Certified Solutions Architect - Professional SAP-C02 — Topic 1 Question 220

Question

A company has IoT sensors that monitor traffic patterns throughout a large city. The company wants to read and collect data from the sensors and perform aggregations on the data. A solutions architect designs a solution in which the IoT devices are streaming to Amazon Kinesis Data Streams. Several applications are reading from the stream. However, several consumers are experiencing throttling and are periodically encountering a ReadProvisionedThroughputExceeded error. Which actions should the solutions architect take to resolve this issue? (Choose three.)

Accepted Answer

Correct answer: A, C, E. The correct answer is A, C, E. Option A: Reshard the stream to increase the number of shards in the stream. Option C: Use consumers with the enhanced fan-out feature. Option E: Use an error retry and exponential backoff mechanism in the consumer logic. Amazon RDS is a managed relational database that handles patching, backups and failover. This option meets the real-time / low-latency performance requirement.
