Pass the AWS Certified Data Engineer – Associate (DEA-C01) exam with a native, offline-first practice app built around real exam scenarios across every domain of the current exam. WHY THIS APP Most Data Engineer quiz apps are thin question dumps with no explanations or a domain mix that doesn't match the real exam. This one is built and weighted to the official DEA-C01 exam guide, and every question — not just the answer key — comes with a full explanation of why the right choice is right and the others are wrong. WHAT'S INCLUDED (FREE) - 100 exam-style questions weighted to match the official DEA-C01 domain breakdown - Every question comes with a detailed explanation referencing official AWS documentation - Choose 5, 10, or 15 questions per practice session - Track your progress, streaks, and score history right on your device - Works fully offline- study on a plane, a commute, anywhere - No account, no sign-up, no ads EXAM DOMAINS COVERED - Data Ingestion and Transformation (34%) - Kinesis, MSK, Glue ETL, DMS, Firehose, EventBridge, MWAA, Lambda - Data Store Management (26%) - S3, Redshift, DynamoDB, Aurora, Lake Formation, OpenSearch, Iceberg/Glue Data Catalog - Data Operations and Support (22%) - CloudWatch, Step Functions, EMR, Glue Data Quality, AWS Batch, Amazon Q Developer - Data Security and Governance (18%) - IAM least privilege, Lake Formation permissions, KMS, Macie, VPC endpoints BUILT FOR REAL STUDYING Every question is written as a scenario a working data engineer would actually face, with distractor answers that test common misconceptions rather than obvious wrong picks.
