Who should take the DEA-C01?
DEA-C01 is an associate-level, role-based certification. There are no formal prerequisites, but AWS recommends hands-on experience — the questions are scenarios, not definitions.
You already build on AWS
You run real workloads and want the credential that matches the job you're already doing — and the salary conversations that come with it.
You're moving into a cloud role
The exam blueprint doubles as a job description. Studying it task statement by task statement is the fastest way to find and close your skill gaps.
You hold a foundational cert
The natural next step on the same platform: deeper services, scenario-based questions, and a credential employers screen for by name.
