DEA-C01 Data Ingestion and Transformation Practice Question
A data engineer needs to ingest data from a SaaS application (Salesforce) into Amazon S3 on a daily basis. Which TWO AWS services can be used for this purpose? (Choose TWO.)
⚠ Common exam trap
It's easy for candidates to confuse AWS DataSync's ability to sync from cloud sources (like EFS) with SaaS applications, but DataSync does not support Salesforce or other SaaS APIs natively.
