Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 220 discussion

To resolve the issue of throttling and ReadProvisionedThroughputExceeded errors in the Amazon Kinesis Data Streams scenario, the solutions architect should take the following actions: 1. A. Reshard the stream to increase the number of shards in the stream: By increasing the number of shards, you can increase the overall throughput capacity of the stream, allowing for more concurrent consumers to read from the stream without being throttled. 2. C. Use consumers with the enhanced fan-out feature: Enhanced fan-out allows for multiple consumers to read from the same shard concurrently, without being limited by the read capacity of the shard. This helps distribute the load and reduces the chances of throttling. 3. E. Use an error retry and exponential backoff mechanism in the consumer logic: Implementing an error retry mechanism with exponential backoff in the consumer logic will help handle throttling errors gracefully. When a ReadProvisionedThroughputExceeded error occurs, the consumer can retry the read operation after a certain delay, gradually increasing the delay between retries to avoid overwhelming the system.

Answer ACE

A, C, E Options

Option (D) "Reshard the stream to reduce the number of shards" is generally not a recommended solution because it reduces the capacity of the stream, which might lead to more throttling issues. Reducing shards should only be considered if you're overprovisioned, and reducing capacity will not negatively impact your consumers. Option (B) "Use the Kinesis Producer Library (KPL) and adjust the polling frequency" may not be directly related to solving the throttling issue. The KPL is primarily used for producing data into the Kinesis stream, not consuming it. Option (F) "Configure the stream to use dynamic partitioning" can be beneficial for even distribution of data but is not directly related to resolving throttling issues. Dynamic partitioning is more about balancing the data across shards and does not increase overall read capacity. So, the most relevant actions to address the throttling issue are (A), (C), and (E).

Correct ACE.

ACE it

ACE is correct

Eliminate B, KPL is for writing. "The Kinesis Producer Library (KPL) simplifies producer application development, allowing developers to achieve high write throughput to a Kinesis data stream. " The error was reading. F, dynamic partitioning is used for different use cases.https://docs.aws.amazon.com/firehose/latest/dev/dynamic-partitioning.html

ACE is correct

not sure about E, but I would go with AC
