💡 Model Answer

A single Lambda invocation cannot process 10 GB of data in one go because of the 15‑minute timeout and 10 GB memory limit. However, you can process 10 GB by breaking the data into smaller chunks, using S3 event triggers to invoke Lambda for each chunk, or orchestrating multiple invocations with Step Functions. For large, sequential processing, services like AWS Glue, EMR, or SageMaker are more suitable because they support long‑running jobs and distributed processing.
