Before you register
How difficult is the AWS DEA-C01 exam?
DEA-C01 is an Associate-level certification with moderate difficulty. The exam focuses on data pipeline design and implementation, with key services including Glue, Kinesis, S3, Redshift, and Athena. Having 1-2 years of AWS data services experience and 1-2 months of systematic preparation is recommended.
What is the difference between DEA-C01 and DAS-C01?
DEA-C01 is Associate-level with a $150 exam fee, focusing on data engineering practices (pipeline construction, ETL, data store management). DAS-C01 is Specialty-level with a $300 exam fee, focusing on the full data analytics lifecycle (collection, processing, analysis, and visualization). DEA-C01 is better suited as an entry-level certification for data engineers.
How much does AWS Glue weigh on the exam?
AWS Glue is the most critical service on the exam, spanning both the Data Ingestion and Transformation (34%) and Data Store Management (26%) domains. You need to deeply understand Glue ETL jobs (Python/Spark), Glue Crawler, Glue Data Catalog, Glue Studio, and Glue job bookmarks.
What is the DEA-C01 exam fee and duration?
The DEA-C01 exam costs $150 USD, lasts 170 minutes, and contains 65 questions (multiple-choice and multiple-response). A score of 720/1000 is required to pass. The certification is valid for 3 years.
What does the Data Security and Governance domain cover?
This domain accounts for 18% of the exam, focusing on Lake Formation data lake permission management, IAM policy design, KMS data encryption, S3 bucket policies and access points, Glue Data Catalog resource policies, and data classification and sensitive data protection (Macie).
