Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Step Functions, AWS Lambda, and Amazon S3.
AWS Step Functions can orchestrate the workflow, AWS Lambda can process files in a serverless manner, and Amazon S3 can store the large files. Option A is wrong because Amazon EMR is not a serverless service and EFS is a network file system, not ideal for serverless batch processing. Option B is wrong because Amazon Kinesis Data Firehose is designed for streaming data, not batch processing of large files. Option D is wrong because Amazon EC2 and EBS are not serverless.
