AWS Certified Developer Associate DVA-C02 Practice Question

Your company's cloud architecture leans heavily on Lambda functions to process e-commerce transactions. The functions must scale automatically and remain unaffected by the state of previous invocations. Currently, a function processes payments by using an external payment gateway and it must reliably handle transactions during peak hours. To ensure that transaction handling by Lambda functions adheres to a stateless design, what should be done?

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

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

  • Use environment variables to store transaction state between invocations.

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