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
✓
Amazon S3
Amazon S3 (Option C) is a serverless object storage service that can store the large files. AWS Lambda (Option E) is a serverless compute service that can process the files, for example by triggering on S3 events. Options A (Amazon EMR) requires a cluster of EC2 instances and is not serverless. Option B (Amazon EC2) requires provisioning servers and is not serverless. Option D (Amazon EFS) is a managed file system that is serverless, but it does not provide compute capabilities and is not the primary serverless compute service needed for processing. Therefore, the correct answers are C and E.
