Short summary
The AWS Certified Developer Associate (DVA-C02) tests practical coding skills across Lambda, DynamoDB, security, CI/CD, and troubleshooting, weighted 32%-26%-24%-18%. Success requires 1+ year AWS experience, 4-10 weeks of study at 8-10 hours/week, and 500+ practice questions. The recommended path uses Stephane Maarek's Udemy course ($15 on sale), AWS documentation, free labs, and two timed exams for validation.
- •Exam covers 4 domains: development with AWS services (32%), security (26%), deployment/CI-CD (24%), troubleshooting (18%)
- •Study timeline: 4-6 weeks with 1+ year AWS experience, 8-10 weeks with 6-12 months experience, 14-16 weeks with no AWS background
