Watch out
Where candidates struggle
This exam tests hands-on development skills. Candidates who understand architecture but lack experience writing code against AWS SDKs and configuring deployment pipelines often miss critical implementation-detail questions.
- 01DynamoDB Keys — Misunderstanding partition keys, sort keys, and GSI/LSI design leads to wrong answers on data modeling and query optimization questions.
- 02Lambda Limits — Not knowing cold start behavior, memory/timeout configuration, and concurrency limits causes errors on serverless architecture questions.
- 03IAM for Apps — Confusing IAM roles, resource policies, and Cognito user/identity pools when securing application access to AWS resources.
- 04CI/CD Services — Mixing up CodeCommit, CodeBuild, CodeDeploy, and CodePipeline responsibilities leads to wrong answers on deployment workflow questions.
- 05Error Handling — Not understanding SQS dead-letter queues, Lambda retry behavior, and Step Functions error handling patterns.
