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 correct because it is a fully managed service that can ingest real-time clickstream data and deliver it to Amazon S3 in near-real-time (typically less than 60 seconds). Option B (AWS DMS) is for database migration, not streaming ingestion. Option C (Amazon Kinesis Data Streams) requires custom consumers to process and deliver data to S3, adding code overhead. Option D (S3 Transfer Acceleration) only speeds up uploads but does not provide streaming ingestion capabilities.
