What is the DEA-C01 AWS Certified Data Engineer Associate exam?
The DEA-C01 AWS Certified Data Engineer Associate exam is an AWS certification at the AWS associate level, in the data engineering category. It checks whether you can design, build, and run data pipelines on AWS. AWS created this exam for people who work with data ingestion, transformation, storage, and operations on a daily basis.
Passing the exam earns you the AWS Certified Data Engineer, Associate credential. Employers use it as a marker that you understand core data services and can apply them to real pipelines, not just to isolated tasks.
There is no formal prerequisite for this exam. AWS recommends that candidates already have hands-on experience with data services, SQL, and ETL or ELT workflows before they sit it. If you are new to data engineering on AWS, plan for extra study time.
How much does the DEA-C01 AWS Certified Data Engineer Associate exam cost?
AWS charges $150 for the official DEA-C01 AWS Certified Data Engineer Associate exam voucher. Cyber VK sells the same official voucher for $48.99, a saving of $101.01, which works out to 67% off the official price.
The voucher you buy from Cyber VK is the real AWS voucher, delivered to your email. It is not a discount code or a promotional trick. You use it to book your exam directly with AWS, the same way you would with a voucher bought at full price. It stays valid for 12 months from the date of purchase, so you can book your sitting whenever you are ready.
What is on the DEA-C01 AWS Certified Data Engineer Associate exam?
The exam has 65 questions and you get 2 hours 10 minutes to answer them. You need a score of 720 (on 100 to 1000 scale) to pass. Questions are grouped into five domains.
| Domain | What it covers |
|---|---|
| Data Ingestion | Bringing data into AWS from source systems, using batch or streaming methods |
| Data Transformation | Cleaning, joining, and reshaping data with ETL and ELT tools |
| Data Store Management | Choosing storage services, file formats, schemas, and lifecycle rules |
| Data Operations | Automating pipelines, scheduling jobs, and monitoring data workflows |
| Security | Setting access controls, encryption, and data governance |
Expect scenario style questions. Most describe a business situation and ask which AWS service, setting, or design choice fits it best, rather than asking you to define a term.
How hard is the DEA-C01 AWS Certified Data Engineer Associate exam?
The exam sits at the associate level, so it expects hands-on comfort with AWS data services, not just familiarity from reading. A passing score of 720 (on 100 to 1000 scale) means most questions need to be answered correctly, so there is little room for guessing your way through.
People who struggle with this exam are often strong in one domain, such as storage, but weaker in another, such as security or operations. Because the exam spans all five domains evenly, a gap in any single area can bring down your overall score.
Hands-on practice with core services such as ingestion and transformation tools tends to matter more than memorizing lists of features. Reading the official exam guide before you start studying helps you see exactly what is in scope.
How to prepare for the DEA-C01 AWS Certified Data Engineer Associate exam
A steady plan across 4 to 6 weeks works well for most candidates who already have some AWS background. Try fifteen free practice questions for this exam to see where your knowledge stands before you commit to a full study plan.
- Week 1: Read the official exam guide and map each domain to the AWS services it covers.
- Week 2: Study data ingestion and transformation services, and build a small pipeline by hand.
- Week 3: Study data store management, covering file formats, partitioning, and schema design.
- Week 4: Study data operations and security, covering monitoring, automation, and access control.
- Week 5: Work through practice questions, then go back and review any domain where you missed answers.
- Week 6: Do a full timed review across all five domains and rest before exam day.
If you already work with AWS data services day to day, you can shorten this to 4 weeks by combining the study weeks above.
Common mistakes people make
Some candidates study only the services they already know well and skip the rest of the exam guide. This leaves gaps in domains like security or operations, which the exam still tests in full.
Others read about a service without ever using it. The exam often asks about behavior you only notice by building something, such as how a service handles retries or partial failures during a pipeline run.
A third mistake is treating the official exam guide as optional. The guide lists the exact task statements the exam is built from, so skipping it means studying without knowing what is actually covered.
Finally, some people leave security and governance study until the last few days before the exam. Security is one of the five domains, so it deserves the same attention as the ingestion and storage topics.
Is the DEA-C01 AWS Certified Data Engineer Associate certification worth it?
The certification is aimed at data engineers, analytics engineers, data platform specialists, BI engineers, and cloud practitioners who build or operate data pipelines. If your work touches these areas, the exam domains map closely to tasks you already do.
The certification can support roles such as data engineer, analytics engineer, cloud data engineer, ETL developer, data platform engineer, and BI or data pipeline specialist. Beyond the exam itself, studying for it usually fills gaps in how you think about a pipeline end to end, from ingestion through to security, which is useful even before you sit the test.
If you already hold, or plan to pursue, other AWS certifications, this one fits alongside credentials such as AWS Certified Solutions Architect Professional (SAP-C02), AWS Certified Machine Learning Engineer Associate (MLA-C01), and AWS Certified Security Specialty (SCS-C02). Cyber VK sells official vouchers for these and other AWS exams as well.
