AWS DevOps Engineer - Professional (DOP-C02) — Practice Questions and Mock Exam

The AWS Certified DevOps Engineer – Professional validates advanced technical proficiency in provisioning, operating, and managing distributed application systems on AWS. It covers CI/CD pipeline automation, infrastructure as code, monitoring and logging, incident response, and security controls across the full software development lifecycle.

This certification targets DevOps engineers, platform engineers, and SREs with two or more years of hands-on experience managing AWS environments. It demonstrates the ability to implement and manage continuous delivery systems, automate security controls, and design highly available and self-healing infrastructure on AWS.

The Pass-IT question pool gives you material to practice for DOP-C02. A Pass-IT mock exam uses 75 questions and a 180-minute time limit; these are practice settings.

SDLC Automation carries the most weight at 22%, covering CI/CD pipeline design, automated testing integration, artifact management, and deployment strategies like blue/green and canary spanning EC2 instances, containers, and serverless compute. Security and Compliance ties with Configuration Management and IaC for second place at 17% each: one scales identity management and automated security controls across accounts, the other packages infrastructure as reusable code and automates account provisioning and governance at scale.

Resilient Cloud Solutions and Monitoring and Logging split 15% apiece, covering architecture spread across multiple Availability Zones and Regions alongside the observability pipelines that catch problems before they escalate. Incident and Event Response closes the blueprint at 14% — the smallest domain, but where event-driven remediation and root-cause analysis live, and a candidate who's automated deployments without automating the response to what breaks is only prepared for half the job.

The exam draws 75 questions (65 scored, 10 unscored) from multiple-choice and multiple-response formats inside a 180-minute window. Questions are scenario-heavy, often describing a multi-stage deployment pipeline, an infrastructure-automation constraint, or an incident already in progress and asking for the next correct action. At 2.4 minutes per question, efficient reading and quick elimination of distractors matter more than exhaustive analysis.

The exam runs through Pearson VUE, either at a testing center or online with a remote proctor, and is offered in English, Japanese, Korean, and Simplified Chinese. Certification holds for 3 years; passing a recertification exam renews it, and because this is a professional-level credential, earning it also renews any associate-level AWS certification you hold.
