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 Kinesis Data Firehose
Amazon Kinesis Data Firehose is the most appropriate solution because it is a fully managed service designed to ingest streaming data and deliver it to destinations like Amazon S3 with near-real-time latency. The company needs continuous clickstream capture and near-real-time processing, which Firehose provides. Option A (AWS Data Pipeline) is for batch processing, not streaming. Option B (AWS Snowball Edge) is for offline data transfer, not real-time. Option D (S3 Transfer Acceleration) improves upload speed but is not a streaming ingestion service.
