Amazon Web Services Data-Engineer-Associate Question Answer

A company has an application that uses an Amazon API Gateway REST API and an AWS Lambda function to retrieve data from an Amazon DynamoDB instance. Users recently reported intermittent high latency in the application's response times. A data engineer finds that the Lambda function experiences frequent throttling when the company's other Lambda functions experience increased invocations.

The company wants to ensure the API's Lambda function operates without being affected by other Lambda functions.

Which solution will meet this requirement MOST cost-effectively?

Increase the number of read capacity unit (RCU) in DynamoDB.

Configure provisioned concurrency for the Lambda function.

Configure reserved concurrency for the Lambda function.

Increase the Lambda function timeout and allocated memory.
