Answer-first summary for fast verification
Answer: Implement exponential backoff in the application code upon encountering the error., Adopt AWS SDKs for DynamoDB integration, which include automatic retry logic.
The correct answers are A and B. Implementing exponential backoff (A) is a cost-effective way to handle the ProvisionedThroughputExceededException error as it helps manage retries more efficiently, reducing the likelihood of hitting throughput limits repeatedly. Using AWS SDKs for DynamoDB (B) is also recommended because these SDKs have built-in best practices, including automatic retry logic with exponential backoff, which can help mitigate throughput exceedance errors. Options C, D, and E involve additional costs and may not be as cost-effective as implementing exponential backoff and using AWS SDKs.
