AWS Certified Developer – Associate (DVA-C02) Study Guide [140 Minute Read]

A First-Principles Approach to AWS Cloud Development

Welcome to the AWS Certified Developer – Associate (DVA-C02) Study Guide. This guide moves beyond surface-level memorization. It is designed to build a robust mental model of how cloud-native development works on AWS — understanding the why behind every Lambda function, every DynamoDB access pattern, and every CI/CD pipeline decision.

Each topic is aligned with the official DVA-C02 Exam Objectives, targeting the scenario-based application skills the exam actually tests. Roughly 60–70% of questions are scenario-based — you'll need to apply concepts to real situations, not just define them.

Exam Details: 65 questions (50 scored + 15 unscored) | 130 minutes | Passing score: 720/1000

Prerequisites: AWS recommends 1+ years of hands-on experience developing and maintaining AWS-based applications, proficiency in at least one high-level programming language, and familiarity with core AWS services (IAM, S3, EC2). The AWS Cloud Practitioner certification is helpful but not required.

Exam Domain Weights

Development with AWS Services dominates at 32% — expect heavy coverage of Lambda, API Gateway, DynamoDB, and SDK interactions. Security (26%) and Deployment (24%) are close behind, so IAM policies, Cognito, CodePipeline, and deployment strategies deserve significant study time. Troubleshooting & Optimization (18%) focuses on CloudWatch, X-Ray, and performance tuning.
