DEA-C01 Data Ingestion and Transformation Practice Question
Which TWO services can be used to ingest streaming data into Amazon S3? (Choose two.)
⚠ Common exam trap
Many exam-takers confuse AWS Glue's ETL capabilities with real-time streaming ingestion, or mistakenly think Amazon Athena can ingest data because it queries S3, but neither service is designed for streaming data ingestion.

Amazon Kinesis Data Streams

Amazon Kinesis Data Firehose is a fully managed service that can directly load streaming data into Amazon S3, Amazon Redshift, or Amazon Elasticsearch Service, with optional data transformation and compression.
