Diagnostic
A calibrated baseline test, taken solo, that maps exactly where you stand across data ingestion and transformation, data store management, and data operations and support before you study anything.
About the DEA-C01 exam
The AWS Certified Data Engineer - Associate (DEA-C01) exam validates the skills to build and run data pipelines on AWS: ingesting streaming and batch data, transforming it with services such as AWS Glue, Amazon EMR and Lambda, choosing and managing data stores, orchestrating and monitoring pipelines, and applying data security and governance. AWS recommends 2–3 years of data engineering or data architecture experience plus 1–2 years of hands-on AWS work. The exam has 65 questions (50 scored, 15 unscored) in 130 minutes, with a scaled passing score of 720. DEA-C01 is the current version, governed by exam guide v1.1 (December 12, 2025), and no DEA-C02 has been announced. Data ingestion and transformation is the largest domain at 34%. Edureify's plan budgets roughly 55–70 hours of study.
The Edureify Readiness System
Edureify runs on one loop: a Diagnostic maps exactly where you stand across data ingestion and transformation, data store management, and data operations and support before you study anything, an adaptive Roadmap turns that into a day-by-day plan weighted toward your actual gaps, a self-paced Practice Loop of questions, mock exams, and spaced review builds mastery topic by topic, and an Intervention layer steps in the moment your progress stalls. Every session feeds back into a live Readiness Score that predicts when you'll be exam-ready and names the specific topics still holding you back — not a completion percentage frozen at the end of a course.
Adaptive roadmap
A day-by-day plan built from your diagnostic and rebuilt automatically as you progress — weighted toward your actual gaps, not a generic syllabus.
Practice loop
Practice questions, mock exams, and spaced-repetition review, self-paced, with mastery tracked across data ingestion and transformation, data store management, and data operations and support.
Readiness prediction
A live score with a predicted ready-by date and the specific topics still dragging it down, recalculated after every session.
Certifying a team for DEA-C01, not just yourself?
Edureify also runs as a team platform for L&D leaders: every team member gets the same self-paced diagnostic-to-readiness loop, and managers get a live dashboard showing each person's Readiness Score, predicted ready-by date, and what's specifically holding them back — plus a portfolio view for reporting on DEA-C01 readiness across the whole team.
How Udemy approaches DEA-C01 prep
Udemy offers "AWS Certified Data Engineer Associate 2026 - Hands On!", a self-paced video course for DEA-C01 that walks through Glue, Kinesis, Redshift and the rest of the AWS data stack. It's sold from $12.99 on sale with lifetime access, which makes it an easy, low-risk way to see how the services fit together.
Udemy doesn't offer a platform-level baseline diagnostic, readiness score or adaptive plan, and practice tests generally come as separate instructor courses. With ingestion and transformation alone worth 34% of DEA-C01, a finished video course won't tell you whether your Kinesis, Glue and orchestration knowledge is actually exam-ready.
Edureify's diagnostic scores you across data ingestion and transformation, data store management, and data operations and support, then weights your daily plan toward the gaps and projects a ready-by date for DEA-C01.

Questions people ask before choosing
Is a hands-on Udemy course enough for DEA-C01?
It's a good way to learn the services; many candidates also add practice exams, since the course alone doesn't measure whether your data store and orchestration knowledge is exam-ready.
Does Udemy refund DEA-C01 courses?
Udemy's standard 30-day refund policy covers eligible courses; read the current terms on Udemy before buying.
How does Edureify estimate when I'll be ready for DEA-C01?
It combines your diagnostic and ongoing practice results into a Readiness Score with a predicted ready-by date, recalculated after every session.
Edureify vs Udemy: which is right for you?
Udemy suits learners who want to see AWS data pipelines built hands-on, at a low price, and who will test themselves separately.
Edureify suits candidates who want to know which of ingestion, storage, or operations is costing them points and when they'll be ready for DEA-C01.
Building pipelines in a demo and answering 65 timed DEA-C01 questions are different skills, and Edureify measures the second one directly.
