About this app

CodeDeploy blue/green, Elastic Beanstalk immutable, or a CloudFormation rolling update? All three look like a way to swap servers without downtime, but only one meets the requirements.
This app prepares you for all six domains of the AWS Certified DevOps Engineer - Professional (DOP-C02) exam, in the same proportions as the real exam, five questions at a time.

DOP-C02 is a professional exam on automating CI/CD, infrastructure as code, multi-account governance, monitoring, and incident response. Many candidates say they know each service on its own but hesitate when services are combined. Which action belongs in which pipeline stage, StackSets automatic deployment, SCPs versus Config rules, metric filters versus subscription filters, the order of lifecycle hooks in appspec.yml: knowing feature names is not enough. The details of how services behave and the order of the requirements decide the result.

All you need is your phone. Any spare moment becomes study time.

■ The same six domains, in the same proportions

・SDLC Automation (22%)
・Configuration Management and IaC (17%)
・Resilient Cloud Solutions (15%)
・Monitoring and Logging (15%)
・Incident and Event Response (14%)
・Security and Compliance (17%)

Your progress by domain maps directly onto the real exam, so your gaps show up as numbers.

■ Key features

【Learn why the other options are wrong】
The most common complaints about practice tests are shallow explanations and recycled questions. Every one of the 300 questions explains not only why the answer is right but also why the tempting wrong options fail, and the details were checked against the official AWS documentation.

【LEAST operational overhead, LEAST downtime, least privilege】
DOP questions often give four setups that would all work and ask for the one that fits the priority. The wrong options here are built the same way (they work, but leave manual steps or only detect a problem after the fact), so you practice the same judgment calls as the real exam.

【Integration questions that combine services】
Questions combine CodePipeline, CodeBuild, and CodeDeploy with Organizations, IAM, KMS, EventBridge, Systems Manager, Config, and CloudWatch, just like the real exam.

【Get used to multiple-response questions】
The real exam includes questions with more than one correct answer. Here you can practice with questions that ask which two steps to combine.

【Up to date with AWS in 2026】
Discontinued services such as OpsWorks and CodeStar, and services closed to new customers such as App Runner and Proton, are never the correct answer, so you won't memorize outdated designs.

【One set per train stop】
Each set has five questions. Fit them into your commute or lunch break.

【Every correct answer counts】
Each correct answer is recorded once, in domain or random practice.

【Finish with exam-style practice】
Random practice (5 to 10 questions) draws from all six domains in the real exam proportions to check your readiness.

【Works offline】
All question data is stored in the app. No connection is needed after download.

【10 languages】
Questions, options, and explanations are available in 10 languages, including Japanese, Korean, Chinese, and German.

【No sign-up】
No account, no login, no daily limits. Start the first question right after installing.
