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.
Built the way a serious exam should be studied
- 420 original scenario-based questions across all 4 current Exam Guide domains, each mapped to its domain and task and reviewed with a source note and last-reviewed date.

- Weak Area Review, Bookmarks, Multiple Response practice, a Custom Session builder, and a Final Cram before test day.
- Standard Timed (65 questions, 130 minutes) and Untimed Study Simulation full mock exams with domain and task breakdowns.

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.
