How hard is the AWS DevOps Engineer Professional exam? +
DOP-C02 is hard because several answers usually work, and AWS wants the one with the least operational overhead. Candidates who pick familiar scripted or manual approaches lose to EventBridge, Systems Manager, and other AWS-native automation answers. Questions also assume multi-account governance with Organizations, SCPs, StackSets, and cross-account pipelines throughout.
What is the DOP-C02 exam format? +
DOP-C02 has 75 questions in 180 minutes, including some unscored research items. Questions are multiple choice and multiple response, delivered at a Pearson VUE test center or online. Scenarios are long and dense, so pacing matters - candidates often spend too long early and rush the final stretch.
What is the DOP-C02 passing score? +
You need a scaled score of 750 on a range of 100 to 1,000. Scoring is compensatory, so strong domains can offset weaker ones. Your score report shows performance by domain, which is the best starting point for a retake plan. Results are typically available within a few business days, and you do not need to pass each domain individually.
How much does DOP-C02 cost and what experience is expected? +
The exam costs 300 USD, plus local taxes where applicable. There is no formal prerequisite, but AWS recommends two or more years of experience provisioning, operating, and managing AWS environments. The certification is valid for three years, and passing it also renews the Developer and CloudOps Engineer associate certifications. After a failed attempt you must wait 14 days.
Which DOP-C02 domain matters most? +
SDLC Automation is the heaviest domain at 22%, covering CodePipeline, CodeBuild, CodeDeploy, and deployment strategies such as blue/green and canary. The other domains cover configuration management and infrastructure as code, resilient cloud solutions, monitoring and logging, incident and event response, and security and compliance. Teams using GitHub Actions or Jenkins day to day often lack depth in AWS-native pipelines.
How long should I prepare for DOP-C02? +
Engineers with hands-on AWS DevOps experience typically need 8 to 12 weeks. Spend time on CodePipeline and CodeDeploy behavior, CloudFormation StackSets, cross-account deployment, and event-driven remediation. Practice full-length timed sessions to build the stamina for three hours of long scenarios. Candidates coming from GitHub Actions or Jenkins should budget extra time for AWS-native pipeline services.
