A developer maintains a serverless application that uses an Amazon API Gateway REST API to invoke an AWS Lambda function by using a non-proxy integration. The Lambda function returns data, which is stored in Amazon DynamoDB.

Several application users begin to receive intermittent errors from the API. The developer examines Amazon CloudWatch Logs for the Lambda function and discovers several ProvisionedThroughputExceededException errors.

The developer needs to resolve the errors and ensure that the errors do not reoccur.

A.

Use provisioned capacity mode for the DynamoDB table, and assign sufficient capacity units. Configure the Lambda function to retry requests with exponential backoff.

B.

Update the REST API to send requests on an Amazon SQS queue. Configure the Lambda function to process requests from the queue.

C.

Configure a usage plan for the REST API.

D.

Update the REST API to invoke the Lambda function asynchronously.
