AWS DEA-C01 Certification Exam

AWS DEA-C01

The AWS Certified Data Engineer - Associate certification validates the ability to build and operate data pipelines on AWS. The exam covers four domains: Data Ingestion and Transformation, Data Store Management, Data Operations and Support, and Data Security and Governance. It draws on services such as AWS Glue, Amazon Kinesis, Amazon S3, Amazon Redshift, Amazon Athena, Amazon EMR, AWS Lake Formation, Amazon DynamoDB, AWS Step Functions and Amazon MWAA. Candidates are tested on choosing and combining these services to ingest, transform, store and govern data at scale, rather than on writing application code. This certification suits data engineers with about a year of hands-on AWS experience.
