AWS Certified Developer – Associate (DVA-C02)

DVA-C02, the AWS Certified Developer – Associate exam, is for people who write code that runs on AWS: 65 questions in 130 minutes, 50 of them scored, and a scaled pass mark of 720 out of 1,000. It assumes a year of hands-on development and asks about the code, not the architecture diagram — how a Lambda function handles a failed batch, why a DynamoDB query is throttling, which permission a cross-account call is missing, how a deployment rolls back on its own. Both practice exams here follow exam guide v2.1 and its four domains in their published weighting.

Most items are short scenarios with a developer qualifier: "with the fewest code changes", "without storing credentials", "at the lowest cost", "with no additional infrastructure". Two or three options usually work in principle; the skill being tested is knowing the one that fits the constraint — a destination instead of a dead-letter queue, a global secondary index instead of a scan, a data key instead of a direct Encrypt call. Every explanation says why the key fits and what each distractor would actually do.

The questions here are original, written to match the style and difficulty of the real exam. They are not reproduced exam content: publishing that breaches the AWS Certification Agreement, and memorising leaked items does not survive contact with a scenario you have not seen. The real exam can also include unscored pretest items on emerging topics such as AI-assisted development; those are not scored, and this exam sticks to the scored content outline.
