Most DVA-C02 prep apps test whether you memorized a service name. They don't test whether you can actually reason through a production issue.
This app is built around the judgment calls the real AWS Certified Developer - Associate exam actually asks about: which AWS service fits a requirement, what the retry or idempotency behavior actually is, where a permission boundary should sit, and what the next debugging step is when a Lambda function or deployment misbehaves. Every question includes a full explanation of why the best answer is best AND why every other choice is wrong or weaker -- not just a checkmark.
Why this app is different
- Serverless Event Flow Lab: reason through API Gateway, Lambda, SQS, SNS, EventBridge, Step Functions, and DynamoDB Streams -- synchronous vs. asynchronous, fanout, ordering, and failure paths, shown as clear node diagrams (no AWS console screenshots to memorize).
- Lambda Configuration & Debug Lab: handler, memory, timeout, concurrency, layers, destinations, DLQ, and VPC access -- read real log output and find the actual misconfiguration.
- SDK Behavior Lab: pagination, retryable vs. non-retryable errors, exponential backoff, credential provider chains, idempotency tokens, and waiters -- the AWS SDK behavior every developer exam question assumes you already know.
- DynamoDB Access Pattern Lab: partition/sort keys, Query vs. Scan, GSI/LSI, conditional writes, transactions, TTL, and hot partitions.
- Retry, DLQ & Idempotency Lab, IAM/Cognito/STS Decision Lab, CI/CD Deployment Strategy Lab, SAM & CloudFormation Reading Lab, and Logs/Metrics/Traces Lab round out all 9 Interactive Labs.

Improved distractor answer quality across the question bank so incorrect choices no longer stand out by length alone -- a content-accuracy pass, no new features.
