AWS Certified DevOps Engineer – Professional (DOP-C02) Practice Questions (Free Sample)

75 questions in a 180-minute window. Of those, 65 are scored and 10 are unscored items AWS uses to calibrate future exam forms — you will not know which are which, so every question gets the same effort. The format mixes multiple choice, where one answer is correct, with multiple response, where two or more are. Confirm current logistics on the AWS Certification site when you book, since AWS sets the format and may change it.

AWS reports a scaled score between 100 and 1000, with 750 required to pass. That conversion does not map linearly to a raw percentage, so 750 is not “75% of the questions right” — AWS adjusts for item difficulty across forms. The honest working equivalent is that you should be scoring 75% or better on high-quality practice sets before you book, which is why Certifym sets the pass mark on its DOP-C02 sets at 75%. Treat it as a floor rather than a target.

SDLC Automation is the single heaviest domain at 22% — pipelines, deployment strategies across EC2, ECS, EKS and Lambda, and the testing gates around them. Configuration Management and Infrastructure as Code and Security and Compliance are joint second at 17% each, so those three together carry well over half the scored questions. Resilient Cloud Solutions and Monitoring and Logging are 15% apiece, and Incident and Event Response is the lightest at 14%. That last one is small but unforgiving: it asks you to reason about what an automated or human response actually does under pressure, which is not something you can revise into place the night before.

AWS’s target profile calls for at least two years of hands-on AWS experience in a DevOps role, plus fluency in a programming or scripting language, infrastructure as code, containers, and CI/CD tooling. That is a description of who the questions are written for, not paperwork you file — nothing stops you booking earlier. What the profile really signals is that the exam assumes you have already lived through a real incident, argued with CloudFormation about a rollback, and rewritten a canary configuration at 2 AM. Candidates who have read about those situations rather than been in them find the option sets much harder to separate.

Yes. Passing DOP-C02 automatically recertifies the AWS Certified CloudOps Engineer – Associate (SOA-C03), and the AWS Certified Developer – Associate (DVA-C02) if it is still current, resetting both to a fresh three-year window. That makes it an efficient recertification path if you already hold those associate credentials. AWS also issues a 50% discount voucher after you pass any AWS certification, which can be applied to a future registration.

They are the two Professional-tier AWS credentials and they sit at the same difficulty ceiling, but they test different work. DOP-C02 is operational — pipelines, configuration management, monitoring, incident response, and the guardrails that keep multi-account delivery safe. SAP-C02 is architectural — landing zones, service selection, migration strategy. Many senior engineers hold both, because the job spans both, but the bodies of knowledge overlap less than the shared “Professional” label suggests. Preparing for one is not preparing for the other.

The sample is a fixed 15-question set spread across the six domains at blueprint proportions, with no account needed. The full Certifym bank is 650 original Professional-tier questions across ten independent 65-question sets, each distributed exactly to the DOP-C02 blueprint — 14 SDLC Automation, 11 Configuration Management and IaC, 10 Resilient Cloud Solutions, 10 Monitoring and Logging, 9 Incident and Event Response, and 11 Security and Compliance — at a 75% pass mark that mirrors the real 750-of-1000 scaled score. Each set is written around a different vertical, so working through several shows you the same domains in a wide spread of real-world contexts rather than the same handful reworded. None of the paid-bank items appear in this sample.
