Amazon Web Services SAP-C02 Question Answer

A company operates an API service in the AWS Cloud. The service is based on an Amazon API Gateway REST API that is integrated with an AWS Lambda function. The Lambda function stores data in an Amazon DynamoDB table. The DynamoDB table is configured with on-demand capacity mode.

An application accesses the API service sporadically during the day. Performance testing showed high variability in response time. The first response to identical requests took longer to process compared to subsequent responses.

Which solution will ensure consistent performance?

Configure a Lambda function endpoint as the target for an Amazon Route 53 record set. Use Route 53 latency-based routing to distribute traffic.

Configure provisioned concurrency for the Lambda function. Use AWS Application Auto Scaling with a target tracking scaling policy to manage concurrency based on usage.

Create an Amazon CloudFront distribution that uses the API Gateway endpoint as an origin. Route API requests by using the CloudFront distribution.

Implement DynamoDB Accelerator DAX. Use provisioned capacity mode and auto scaling for the DynamoDB table.
