Question

A serverless application uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. The Lambda function needs permissions to read and write to the DynamoDB table. Which solution will give the Lambda function access to the DynamoDB table MOST securely?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Create an IAM role that includes Lambda as a trusted service. Attach a policy to the role that allows read and write access to the DynamoDB table. Update the configuration of the Lambda function to use the new role as... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. An IAM role grants temporary, least-privilege permissions to AWS resources without long-term credentials.
