AWS Certified Developer Associate DVA-C02 Practice Question

Your company's cloud architecture leans heavily on AWS Lambda to process e-commerce transactions. The functions must scale automatically and remain unaffected by the state of previous invocations. A payment-processing function calls an external gateway and must reliably handle transactions during peak hours. To ensure the function adheres to a stateless design, what should you do?

  • Store transaction state data in an external database or caching service such as Amazon DynamoDB or Amazon ElastiCache.

  • Use environment variables to store transaction state between invocations.

  • Configure the Lambda function to process transactions asynchronously using an internal queue.

  • Enable automatic scaling on the Lambda function to handle the increased number of transactions.
