AWS Certified Developer Associate DVA-C02 Practice Question

Retries that use exponential backoff gradually increase the delay between attempts, reducing the chance of immediate repeated throttling. Adding jitter randomizes each delay so that multiple clients do not retry in lockstep, which further lessens contention on the service. This pattern is the AWS-recommended way to handle transient throttling errors. Longer timeouts, circuit breakers, or scaling compute resources can each address other failure modes but do not directly resolve the cause of HTTP 429 responses as effectively as exponential backoff with jitter.
