AWS Certified Developer – Associate DVA-C02

Exam Overview

The AWS Certified Developer – Associate (DVA-C02) exam validates the ability to develop, secure, deploy, troubleshoot, and optimize AWS Cloud applications. This is a developer-focused exam: scenarios usually ask for the best application-level implementation choice, not a full enterprise architecture redesign. The exam favors solutions that are managed (use AWS features instead of custom code), loosely coupled (avoid synchronous dependencies when async fits), least privilege (grant only required actions and resources), observable (metrics, logs, traces, alarms), repeatable (immutable artifacts and IaC), resilient (retries, duplicates, partial failures, rollback), and access-pattern driven (choose data store from query pattern). Before comparing answers, identify the primary requirement, scope, constraint words (MOST secure, least overhead, near real time, ordered, temporary), and failure model.
