question 577

Multiple Choice

A company has a web application that uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. A recent marketing campaign has increased demand. Monitoring software reports that many requests have significantly longer response times than before the marketing campaign. A solutions architect enabled Amazon CloudWatch Logs for API Gateway and noticed that errors are occurring on 20% of the requests. In CloudWatch, the Lambda function Throttles metric represents 1% of the requests and the Errors metric represents 10% of the requests. Application logs indicate that, when errors occur, there is a call to DynamoDB. What change should the solutions architect make to improve the current response times as the web application becomes more popular?

• A) Increase the concurrency limit of the Lambda function
• B) Implement DynamoDB auto scaling on the table
• C) Increase the API Gateway throttle limit
• D) Re-create the DynamoDB table with a better-partitioned primary index
