AWS Certified DevOps Engineer — Professional (DOP‑C02) Practice Exams
About the AWS DOP-C02 exam
Exam at a glance
One of two AWS Professional certifications (alongside SAP-C02 Solutions Architect Professional), focused on DevOps engineering.
Who it's for
Senior DevOps engineers, Site Reliability Engineers (SREs), and Platform Engineers who build and operate CI/CD pipelines, infrastructure as code, observability stacks, and resilient production systems on AWS. AWS recommends 2+ years of hands-on AWS DevOps experience plus solid scripting/programming chops.
Domain weighting
- SDLC Automation: 22%
- Configuration Management and Infrastructure as Code: 17%
- Resilient Cloud Solutions: 15%
- Monitoring and Logging: 15%
- Incident and Event Response: 14%
- Security and Compliance: 17%
Prerequisites
AWS strongly recommends passing the Solutions Architect Associate (SAA-C03) or Developer Associate (DVA-C02) first, but does not formally require either. The exam assumes deep familiarity with the AWS DevOps tooling chain — going in cold without Associate-level foundation is rough.
Why take this certification
- Senior-tier credential. DOP-C02 is one of only two AWS Professional certifications. Earning it signals you can own production environments end-to-end — design, deploy, observe, recover.
- Strong compensation. AWS Certified DevOps Engineer – Professionals earn an average of $140,000–$155,000 USD per year in the United States, with senior platform-engineering and SRE roles commonly clearing $170,000+.
- Cross-functional scope. Unlike specialty certs that go deep in one domain, DOP-C02 spans CI/CD, IaC, containers, serverless, observability, incident response, and compliance automation. The breadth maps directly to platform-team and SRE day-jobs.
- Operates the AWS Well-Architected Framework in practice. Where the Architect track designs against the framework's five pillars, DOP-C02 tests how you actually operate against them — automating recovery, instrumenting reliability, enforcing security and compliance at the pipeline level.
What you'll learn in the DOP-C02 exam
DOP-C02 validates that you can build, deploy, and operate production-grade workloads on AWS using the full DevOps tooling chain. Most questions are long scenario stems describing a real-world workload with constraints — uptime, recovery, compliance, cost — and ask you to choose the right automation, deployment strategy, or operational response.
Core AWS services you'll be tested on
- CI/CD: CodePipeline, CodeBuild, CodeDeploy, CodeArtifact, and third-party integration (GitHub Actions, Jenkins) into the AWS toolchain.
- Infrastructure as Code: CloudFormation (stacks, change sets, StackSets, drift detection), AWS CDK, Terraform on AWS, Service Catalog for governed self-service.
- Container orchestration: ECS (EC2 and Fargate launch types), EKS (managed node groups, Fargate profiles, IRSA), App Runner, ECR (image scanning, lifecycle policies).
- Serverless deployment patterns: Lambda (versions, aliases, traffic shifting), SAM (templates, local invoke, deploy), EventBridge (rules, schedules, event buses, archive/replay), Step Functions.
- Deployment strategies: Blue/green and canary deployments via CodeDeploy and Lambda traffic shifting; rolling updates on ECS/EKS; chaos engineering basics with AWS Fault Injection Service.
- Observability: CloudWatch (metrics, alarms, Logs, Logs Insights, Synthetics, ServiceLens), X-Ray, AWS Distro for OpenTelemetry, Amazon Managed Prometheus (AMP), Amazon Managed Grafana (AMG).
- Incident response automation: Systems Manager Automation (runbooks), SSM Incident Manager (response plans, on-call schedules), EventBridge → Lambda automated remediation.
- Compliance automation: AWS Config (rules, conformance packs, remediation), Security Hub (standards, findings), Audit Manager (evidence collection), GuardDuty, Inspector.
Architectural patterns you'll need to recognize
- Designing multi-account CI/CD pipelines with cross-account roles and centralized artifact stores.
- Implementing blue/green deployments for EC2, Lambda, ECS, and EKS workloads — and choosing the right strategy per workload type.
- Building immutable infrastructure with golden AMIs (EC2 Image Builder) and signed container images.
- Automating compliance-as-code: drift detection, auto-remediation, evidence collection for SOC 2 / HIPAA / PCI audits.
- Designing observability for SLO/SLI tracking with CloudWatch composite alarms and X-Ray service maps.
- Implementing automated incident response: EventBridge rules triggering Lambda or SSM Automation, paging via Incident Manager.
How the practice exams help
Each free question and every premium exam mirrors the scenario-style format AWS uses on Professional-tier exams — long stem, multiple plausible options, often one or two correct. Detailed explanations cover not just why the right answer is right but why the distractors are wrong, so you learn the operational trade-offs (when to choose CodeDeploy over Lambda traffic shifting, when to use AMP over CloudWatch metrics) rather than memorizing service flags.
How to prepare for the DOP-C02 exam
DOP-C02 is a depth-and-breadth exam — there are no easy questions, and the scenarios assume you've actually shipped production CI/CD pipelines on AWS. Recommended approach:
- Pass an Associate-tier exam first (recommended). AWS strongly recommends SAA-C03 or DVA-C02 as a foundation. Skipping straight to DOP-C02 is possible but painful — the exam assumes Associate-level fluency with EC2, VPC, IAM, S3, RDS, and Lambda as a baseline.
- Study AWS DevOps services (5–6 weeks). Work through the official AWS DOP-C02 exam guide and the AWS Skill Builder DOP-C02 learning path. Go deep on CodePipeline / CodeBuild / CodeDeploy, CloudFormation + CDK, ECS / EKS, and CloudWatch + X-Ray — these dominate the exam.
- Hands-on labs (4–5 weeks). Build real pipelines end-to-end: multi-stage CodePipeline with cross-account deploy, blue/green ECS deployment via CodeDeploy, Lambda canary with traffic shifting, CloudFormation StackSets, AWS Config conformance packs with auto-remediation. Hands-on experience is non-negotiable for Professional-tier scenario questions.
- Review AWS whitepapers (1–2 weeks). Read the AWS Well-Architected Framework with extra focus on the Operational Excellence and Reliability pillars, plus the DevOps and Serverless lens whitepapers. These map directly to exam scenarios.
- Practice exams (2 weeks). Take timed practice tests to identify weak areas. Detailed explanations on every answer option help you learn the reasoning behind each trade-off. Aim for consistent 80%+ scores before scheduling — Professional exams punish guessing.
Recommended timeline
12–16 weeks of focused study (10–15 hours per week) for experienced DevOps engineers with prior AWS exposure. Candidates without Associate-level certification or significant AWS production experience should plan for 16–20 weeks.

Frequently asked questions
Are these actual exam questions?
No. All Nex Arc AWS DOP-C02 practice questions are original content based on the provider's published exam blueprint, official documentation, and real-world scenarios across every topic the exam covers. We do not offer brain dumps, leaked questions, or actual exam content. Using or distributing real exam questions violates certification provider agreements and can result in certification revocation.
How many questions are in the AWS DOP-C02 exam?
The AWS DOP-C02 exam consists of 75 questions that you need to complete in 180 minutes. Questions are either multiple choice (one correct answer) or multiple response (two or more correct answers).
What's the DOP-C02 passing score?
The passing score is 750 out of 1000. AWS Professional-tier certifications use a higher passing threshold than Associate-tier exams (which require 720). AWS uses a scaled scoring model, so not all questions carry the same weight. Focus on understanding architectural and operational trade-offs rather than memorizing service flags.

What are the prerequisites for the DOP-C02 exam?
AWS strongly recommends passing the Solutions Architect Associate (SAA-C03) or Developer Associate (DVA-C02) before attempting DOP-C02, but does not formally require either. The ideal candidate has 2+ years of hands-on experience provisioning, operating, and managing AWS environments, plus solid scripting/programming and CI/CD experience. DOP-C02 assumes deep familiarity with the AWS DevOps tooling chain (CodePipeline, CodeBuild, CodeDeploy, CloudFormation), so candidates without that background should expect a steep learning curve.
How long is the DOP-C02 certification valid?
AWS certifications are valid for three years from the date you pass the exam. To recertify DOP-C02, you must retake the current version of the exam — there is no higher-tier exam in the DevOps track to upgrade to. A 50% discount voucher for the recertification exam is available through your AWS Certification Account. AWS does NOT offer Skill Builder credits or a continuing-education recertification path — exam-based recertification is the only option.
What's the exam cost and can I retake it if I fail?
The DOP-C02 exam costs $300 USD globally (converted to local currency). The exam is delivered through Pearson VUE at testing centers or via online proctoring. If you fail, you must wait 14 days before retaking the exam at full price. There is no limit to the number of attempts, but each attempt requires a new $300 payment. AWS occasionally offers 50% discount vouchers for recertification or through AWS Partner Network programs. Practice thoroughly before attempting to minimize retake costs.
What AWS services are most heavily tested on DOP-C02?
DOP-C02 covers the full AWS DevOps tooling chain: CodePipeline, CodeBuild, CodeDeploy, CodeArtifact (CI/CD); CloudFormation, CDK, Service Catalog (IaC); ECS, EKS, App Runner, ECR (containers); Lambda, SAM, EventBridge (serverless); CloudWatch, X-Ray, Distro for OpenTelemetry, AMP, AMG (observability); Systems Manager (Automation, Incident Manager, Parameter Store); Config, Security Hub, Audit Manager, GuardDuty, Inspector (compliance + security); plus Auto Scaling, ELB, Route 53, and Global Accelerator for resilient cloud solutions. Expect heavy scenario-based questions on blue/green and canary deployments.
How does DOP-C02 differ from the previous DOP-C01 version?
DOP-C02 (released March 2023) restructured the exam into six domains (down from seven on DOP-C01) and added significantly more emphasis on container orchestration (ECS/EKS/App Runner), serverless deployment patterns (Lambda, SAM, EventBridge), and observability with AWS Distro for OpenTelemetry, Amazon Managed Prometheus, and Amazon Managed Grafana. SDLC Automation remains the largest domain (~22%), but Configuration Management and IaC grew to ~17% with deeper CDK and Service Catalog coverage. Security and Compliance also expanded to ~17% with Audit Manager and Security Hub additions. The exam length stayed at 75 questions / 180 minutes.
Can I retake the DOP-C02 exam if I fail?
Yes. AWS allows retakes after a 14-day waiting period. You pay the full $300 exam fee again. There is no limit on total attempts.
