DEA-C01 Data Ingestion and Transformation Practice Question
Which TWO AWS services can be used as sources for AWS Glue ETL jobs? (Choose two.)
⚠ Common exam trap
The DEA-C01 exam often tests the misconception that any AWS service that stores or serves data (like Route 53 for DNS records or CloudFront for cached content) can be a Glue source, but Glue only supports sources that provide a direct data access interface (e.g., object storage, databases, or streaming services like Kinesis).

Correct answer & explanation
✓
Amazon S3
Amazon S3 is a fully managed object storage service that serves as a common source for AWS Glue ETL jobs. Glue can read data from S3 using its built-in crawlers and connectors, supporting formats like Parquet, JSON, CSV, and Avro. The Glue Data Catalog can reference S3 locations, and ETL scripts can directly read from S3 buckets via the s3:// protocol.
