Uploaded citizen documents must be virus-scanned asynchronously, with infected files moved to a quarantine bucket without blocking the upload API. Which event-driven design fits?
Select an answer to reveal the explanation.
Short Explanation
S3 rings the doorbell; Lambda answers with a scan and escorts bad files to quarantine—upload stays snappy. Making clerks babysit every PUT or banning uploads entirely isn’t event-driven architecture.
Full Explanation
Event-driven security processing commonly uses S3 event notifications to invoke Lambda for asynchronous scanning and quarantine moves, keeping the upload path loosely coupled. Manual desktop gates or rejecting cloud uploads altogether fail the scalable event-driven requirement.
