AWS Certified Data Engineer Associate DEA-C01 Practice Question

An analytics team uses an S3 event notification to invoke a Python Lambda function that enriches each uploaded JSON file. A nightly batch uploads about 3,000 objects within 5 minutes, but invocations are throttled because the account concurrency limit is 1,000 and other functions consume most of it. The team must ensure all objects are processed within the 5-minute window without affecting other functions. What should they do?

  • Increase the function's memory size to shorten duration and rely on Lambda's burst concurrency to clear the backlog.

  • Enable 3,000 units of provisioned concurrency for the function during the batch window.

  • Send S3 events to an SQS queue and invoke the Lambda function with a batch size of 10 and the default concurrency settings.

  • Configure a reserved concurrency of 3,000 for the function and request an account concurrency limit increase to at least 3,000.
