Complete Overview
The AWS Certified DevOps Engineer - Professional exam, exam code DOP-C02, is a 180-minute professional-level certification from Amazon Web Services that costs $300 USD. It is written for people already doing the DevOps engineer job, and AWS recommends two or more years of experience provisioning, operating, and managing AWS environments, plus experience with the software development lifecycle and programming or scripting.
The exam delivers 75 questions. Only 65 of them affect your score; the other 10 are unscored pretest items that AWS uses to evaluate future questions, and they are not identified on screen. Questions come in two response types: multiple choice with one correct answer among four options, and multiple response with two or more correct answers among five or more options. Results are reported on a scaled range of 100 to 1,000 with a minimum passing score of 750. Scoring is compensatory, so a weak section does not fail you on its own; only the overall scaled score decides pass or fail.
Six content domains carry fixed weights. SDLC Automation is the largest at 22 percent of scored content, followed by Configuration Management and IaC at 17 percent, Security and Compliance at 17 percent, Resilient Cloud Solutions at 15 percent, Monitoring and Logging at 15 percent, and Incident and Event Response at 14 percent. AWS publishes the full task statements and the in-scope service list in the DOP-C02 exam guide, which runs to roughly a dozen service categories from Analytics through Storage.
Delivery is through Pearson VUE, either at a test center or as an online proctored appointment. The exam is offered in English, Japanese, Korean, and Simplified Chinese, and candidates taking a localized version can toggle to English mid-exam. Non-native English speakers taking the English form can request the ESL +30 accommodation once, which adds 30 minutes to every future AWS exam registration.
The certification is valid for three years. AWS gives holders two ways to keep it current: pass the latest version of the exam again for another three years using the 50 percent discount voucher in your certification account, or complete maintenance activities on AWS Skill Builder with a paid subscription for one additional year. Failing the exam means a mandatory 14 calendar day wait before a retake, with the full $300 fee due each attempt and no cap on the number of attempts. Passing locks you out of retaking the same exam for two years unless AWS publishes a new exam series code.
Price varies by currency. AWS lists the professional-level fee as $300 USD, 256 EUR, 449 AUD, 40,000 JPY, 394,575 KRW, and 2,113 CNY, and updates foreign exchange rates at least annually in May.
Why Get AWS Certified DevOps Engineer Professional Certified?
DOP-C02 is one of only three AWS professional-level certifications, and it is the one that maps to build and release work rather than architecture. Passing it also renews AWS Certified Developer - Associate and AWS Certified CloudOps Engineer - Associate for three years.
The blueprint forces breadth across 11 AWS service categories in a single 180-minute sitting, so preparing for it fills gaps that day-to-day work on one team rarely covers.
Salary data for this credential sits in the $130k-$180k band, which reflects the professional tier rather than associate-tier DevOps roles.
The $300 fee buys a credential valid for three years, and renewal uses a 50 percent discount voucher that AWS deposits in your certification account, so the ongoing cost is $150 every three years.
Two of the six domains, Configuration Management and IaC at 17 percent and Security and Compliance at 17 percent, are built around multi-account governance with AWS Organizations, Control Tower, and service control policies. That is the exact skill set platform teams hire for.
The exam guide names AWS Fault Injection Simulator, AWS Resilience Hub, and AWS Proton as in scope, which pushes candidates into resilience tooling that most engineers never touch until an incident forces it.
Results land in your AWS Certification Account within five business days, and the downloadable PDF score report breaks out performance by section so you know exactly where to study if you need a retake.

Exam Domains & Topics
The largest domain covers building CI/CD pipelines, wiring automated testing into them, producing and managing artifacts, and choosing deployment strategies for instance, container, and serverless targets. AWS expects you to reason about pipeline patterns in both single-account and multi-account environments, and to troubleshoot deployments that fail partway through.
Key Topics to Master:
- Pipeline deployment patterns for single-account and cross-account setups
- Build configuration with AWS CodeBuild and buildspec files
- Managing build and deployment secrets with AWS Secrets Manager and Systems Manager Parameter Store
- Artifact repositories: AWS CodeArtifact, Amazon S3, Amazon ECR
- EC2 Image Builder for automating instance and container image builds
- CodeDeploy deployment configurations and blue/green plus canary methods
- Running unit, integration, load, and security tests at the right pipeline stage
- Mutable versus immutable deployment patterns
- Measuring application health from application exit codes
This domain tests defining reusable infrastructure, automating account creation and onboarding across a multi-account and multi-Region estate, and building automation for large-scale operational tasks. It reaches beyond template authoring into governance: standardizing account provisioning, applying guardrails, and keeping software compliant through Systems Manager.
Key Topics to Master:
- AWS CloudFormation, AWS SAM, and AWS CDK template composition
- CloudFormation StackSets across accounts and Regions
- AWS Organizations and AWS Control Tower for account provisioning
- Service control policies and cross-account role assumption
- AWS Config, Security Hub, GuardDuty, and Detective as scaled governance controls
- AWS Service Catalog and CloudFormation modules for reusable patterns
- Systems Manager State Manager and Patch Manager for desired state
- Lambda and Step Functions for complex automation workflows
Tied with IaC for second place by weight, this domain covers identity and access management at scale, automating security controls and data protection, and building security monitoring and auditing. Questions push on least privilege design, permissions boundaries, credential rotation for machine identities, and defense in depth across accounts and Regions.
Key Topics to Master:
- IAM users, groups, roles, identity providers, and identity-based versus resource-based policies
- Federation with IAM Identity Center and IAM identity providers
- IAM permissions boundaries for delegated permission management
- Attribute-based and role-based access control patterns
- Automated credential rotation with AWS Secrets Manager
- Network controls: security groups, network ACLs, AWS Network Firewall, AWS WAF, AWS Shield
- Encryption in transit and at rest with AWS KMS, CloudHSM, and AWS Certificate Manager
- Amazon Macie for sensitive data discovery at scale
- CloudTrail, AWS Config, VPC Flow Logs, and CloudFormation drift detection for auditing
This domain asks you to translate business requirements into resilience targets, remove single points of failure, scale workloads, and build automated recovery that meets stated RTO and RPO numbers. Expect scenarios that name a recovery objective and ask which multi-AZ or multi-Region pattern satisfies it at acceptable cost.
Key Topics to Master:
- Multi-AZ and multi-Region deployment patterns for compute and data layers
- Cross-Region features of DynamoDB, Amazon RDS, Route 53, Amazon S3, and CloudFront
- Pilot light and warm standby disaster recovery strategies
- Auto scaling metrics and policy selection
- Deploying container workloads on Amazon ECS and Amazon EKS
- Serverless scaling with API Gateway, Lambda, and AWS Fargate
- AWS Backup for cross-Region backup and restore
- Load balancer configuration for cross-AZ and backend failure recovery
Collection, aggregation, and storage of logs and metrics comes first, then auditing and analysis to detect issues, then automating monitoring and event management. The domain leans heavily on Amazon CloudWatch mechanics, including the difference between metric filters, subscription filters, and metric streams, and on where AWS X-Ray fits.
Key Topics to Master:
- CloudWatch namespaces, dimensions, and metric resolution
- Metric filters that create CloudWatch metrics from log events
- CloudWatch Logs subscription filters to Kinesis, Lambda, and OpenSearch Service
- CloudWatch metric streams to Amazon S3 or Kinesis Data Firehose
- CloudWatch Logs Insights query syntax and Amazon Athena log analysis
- CloudWatch anomaly detection alarms
- AWS X-Ray tracing for containers, API Gateway, and Lambda
- Log retention lifecycles and KMS encryption of log data
- CloudWatch agent and SSM Agent installation on EC2 instances
The smallest domain covers managing event sources, applying configuration changes in response to events, and troubleshooting system and application failures. Scenarios typically start with a symptom, such as a failed CodePipeline execution or an ECS task that will not stabilize, and ask which service produces the evidence you need.
Key Topics to Master:
- Event sources: AWS Health, Amazon EventBridge, AWS CloudTrail
- Event-driven architecture patterns including fan out, streaming, and queuing
- Event processing workflows with SQS, SNS, Kinesis, Lambda, and Step Functions
- Remediating non-desired state with AWS Config remediation actions
- Fleet configuration changes through AWS Systems Manager
- Root cause analysis of failed CodePipeline, CodeBuild, CodeDeploy, and CloudFormation runs
- Diagnosing auto scaling, Amazon ECS, and Amazon EKS process failures
- Systems Manager OpsCenter for operational item tracking

Common Mistakes to Avoid
Reading the 750 passing score as 75 percent and calibrating practice results against that number.
750 is a scaled score on a 100 to 1,000 range, not a percentage of questions answered correctly. AWS sets the raw cut point with a modified Angoff panel and then equates each exam form statistically. Judge readiness by consistent domain-level accuracy on full-length practice sets, not by hitting a 75 percent figure.
Studying AWS CodeCommit as a core pipeline service because older DOP course material centers on it.
The DOP-C02 in-scope services list under Developer Tools names CodeArtifact, CodeBuild, CodeDeploy, CodeGuru, CodePipeline, CodeStar, Fault Injection Simulator, and X-Ray. Spend your source-control study time on how pipelines integrate with version control generally, and put the saved hours into CodeDeploy and CodeBuild behavior.
Learning CodeDeploy deployment configurations as a single list without tying each one to a compute platform.
In-place and one-at-a-time style configurations apply to EC2 and on-premises deployments, while linear and canary traffic-shifting configurations apply to Lambda and Amazon ECS. Build one deployment on each platform in a sandbox so the pairing is muscle memory rather than a memorized list.
Confusing CloudFormation nested stacks with StackSets when a scenario spans multiple accounts.
Nested stacks decompose one deployment inside a single account and Region. StackSets deploy the same template across many accounts and Regions from an administrator account, and integrate with AWS Organizations for service-managed permissions. Domain 2 is 17 percent of scored content and multi-account questions appear throughout it.
Treating CloudWatch metric filters, subscription filters, and metric streams as interchangeable ways to move log data.
Metric filters turn log events into CloudWatch metrics. Subscription filters push log events in near real time to Kinesis, Lambda, or OpenSearch Service. Metric streams push metrics, not logs, to S3 or Kinesis Data Firehose. Build one of each in a sandbox account; the distinction shows up repeatedly in the 15 percent monitoring domain.
Preparing as though DOP-C02 is an expanded SysOps or Developer associate exam, focused on service facts.
Professional-level questions present a scenario with an explicit constraint and several workable answers. The constraint word decides the answer: least operational overhead, fastest rollback, lowest cost, no downtime, or meets a stated RPO. Highlight the constraint before you read the options.
Not budgeting time for the long question stems and running out of clock in the last third.
75 questions in 180 minutes averages 2 minutes 24 seconds per question, and professional-level stems can run several paragraphs. Practice with a hard rule: if a question is not resolved in three minutes, flag it and move on. The review screen at the end lets you return to everything you flagged.
Using the on-screen Comment button to report question issues during the exam.
AWS states that time spent posting comments is subtracted from your exam time limit. Flag the question instead, finish the exam, then add comments in the review pass if you still have minutes to spare.
Skipping the resilience tooling in the in-scope list because it never comes up at work.
AWS Fault Injection Simulator, AWS Resilience Hub, AWS Elastic Disaster Recovery, and AWS Proton are all named in the DOP-C02 in-scope services list. You do not need production depth, but you need to recognize which problem each one solves when it appears as a plausible distractor.
Exam Day Tips
- 1
At a Pearson VUE test center you must present two primary IDs, or one primary and one secondary ID. For an online OnVUE appointment, one primary ID is enough. The first and last name on every ID must be identical to the name in your AWS Certification Account.
- 2
Name mismatches cannot be fixed on test day. Change your name in your AWS Certification Account at least two business days before the appointment, or open a case with AWS Training and Certification Customer Service and wait for it to process before you schedule.
- 3
For online proctored exams you may not stand up or leave the camera view for any reason for the full 180 minutes, including restroom breaks. Plan hydration accordingly.
- 4
At a test center you may take an unscheduled break, but the exam clock keeps running, you cannot leave the building, and you must repeat the check-in steps to re-enter.
- 5
You can launch an online exam up to 30 minutes early. If you are more than 15 minutes late, or your machine fails the system test, the appointment is forfeited along with the $300 fee.
- 6
You get five minutes to read and accept the Candidate Code of Conduct. Letting that screen time out ends the exam with no refund, so accept it promptly.
- 7
The timer sits in the upper right and warns you at five minutes remaining. Use Flag for Review on anything unresolved, then work the review screen filtered to flagged questions.
- 8
If you registered for the Japanese, Korean, or Simplified Chinese version, the English toggle is available in-exam. Use it on any question where the translation reads ambiguously.
- 9
Do not expect a score on screen. Final results post to your AWS Certification Account within five business days, and the downloadable PDF score report includes section-level classifications.
Career Paths & Salary Ranges

Frequently Asked Questions
What happens if I fail the DOP-C02 exam?
You must wait 14 calendar days from the failed attempt before you are eligible to retake it. There is no limit on the number of attempts, but you pay the full $300 registration fee every time. Your score report, available in your AWS Certification Account within five business days, includes section-level performance classifications you can use to target the retake.
How much does the exam cost outside the United States?
AWS lists the professional-level exam fee as $300 USD, 256 EUR, 449 AUD, 40,000 JPY, 394,575 KRW, and 2,113 CNY. Indian rupee pricing of 25,659 INR is accepted only on the Pearson Mindhub voucher store. Applicable taxes may be added, and AWS updates foreign exchange rates at least annually in May with a minimum of 30 days notice.
What is the passing score, and is it a percentage?
The passing score is 750 on a scaled range of 100 to 1,000, and it is not a percentage. AWS sets the raw cut point using the modified Angoff technique with a panel of subject matter experts, then statistically equates other exam forms so that forms of differing difficulty hold candidates to the same standard. All AWS professional-level and specialty exams use 750; associate exams use 720 and foundational exams use 700.
How long do results take?
Final results post to your AWS Certification Account within five business days after the close of the exam. Once available, the Exam History tab shows the result, and for scaled-scoring exams you can download a PDF score report. Results can take longer if they are held for security or technical review.
How many questions are actually scored?
65 of the 75 questions affect your score. The remaining 10 are unscored pretest items that AWS uses to evaluate questions for future scored use, and they are not marked on screen. Because you cannot tell which is which, treat every question as scored. Unanswered questions are marked wrong and there is no penalty for guessing.
What ID do I need to bring?
For a test center appointment you need two primary IDs, or one primary and one secondary ID. For an online OnVUE appointment you need one primary ID. A primary ID must be an original, unexpired, government-issued document showing your first and last name in Roman characters, a recent recognizable photo, and a visible signature. Digital, photocopied, laminated paper, and expired IDs are refused, as are Canadian Health Cards and the U.S. DoD Common Access Card.
What are the rules for the online proctored version?
Online proctoring runs through Pearson VUE OnVUE and is available for all AWS certification exams. English proctoring is available 24 hours a day, seven days a week; Japanese proctoring runs Monday to Saturday 9 a.m. to 4 p.m. JST, and Mandarin proctoring for mainland China customers runs Monday to Friday 8 a.m. to 5 p.m. CST. You must communicate with the proctor to complete check-in, and you cannot leave the camera view at any point during the exam.
Can I take breaks during the exam?
AWS does not configure scheduled breaks for any of its certification exams. At a test center you may take an unscheduled break, but the 180-minute clock keeps running, you cannot leave the building, and you must complete check-in again to return. For online proctored exams and kiosk testing, no breaks are permitted at all.
Are any reference materials, notes, or a calculator allowed?
No. At a test center your belongings are stored according to staff instructions before you enter the testing room, and online proctored candidates complete a testing environment check with the proctor before the exam is released. Specific comfort aids such as medicines and medical devices do not require prior approval; Pearson VUE publishes the current comfort aid list.
Can I get extra time or other accommodations?
Yes. Accommodations for documented disabilities are arranged in advance with Pearson VUE and must be requested before you schedule each exam. Separately, non-native English speakers taking an exam in English can request the ESL +30 accommodation, which adds 30 minutes. ESL +30 is requested once through the Request Exam Accommodations button in your AWS Certification Account and then applies to all future registrations.
How do I renew the certification when the three years are up?
You have two options. Renewing means passing the latest version of the DOP-C02 exam, which adds three years from the date you pass and can be paid for with the 50 percent discount voucher AWS places in your certification account. Maintaining means completing maintenance activities on AWS Skill Builder with a paid subscription, which adds one year. Your certification must still be active to do either, and maintenance requires that it be within 90 days of expiration.
Does passing DOP-C02 renew any of my other AWS certifications?
Yes. Passing the AWS Certified DevOps Engineer - Professional exam recertifies AWS Certified Developer - Associate and AWS Certified CloudOps Engineer - Associate (including the earlier AWS Certified SysOps Administrator - Associate) for three years. It does not renew AWS Certified Solutions Architect - Associate, which requires either its own exam or the Solutions Architect - Professional exam.
How does DOP-C02 compare to AWS Certified Solutions Architect - Professional?
Both are professional-level, both cost $300, both run 180 minutes with 75 questions, and both require a scaled 750 to pass. The difference is content. DOP-C02 weights SDLC Automation at 22 percent and centers on pipelines, deployment strategies, monitoring, and incident response. Solutions Architect - Professional centers on designing new and migrated architectures, cost optimization, and organizational complexity. Engineers who own deployments usually find DOP-C02 the more natural first professional exam.
How does it compare to AWS Certified CloudOps Engineer - Associate?
CloudOps Engineer - Associate, which replaced the SysOps Administrator - Associate exam, is a 130-minute associate-level exam requiring a scaled 720. DOP-C02 is longer, costs twice as much, and expects you to design automation across accounts rather than operate a single environment. Passing DOP-C02 also recertifies the associate credential, so many candidates hold both.
Can I reschedule or cancel my appointment?
You can reschedule up to 24 hours before the appointment, and each exam appointment can be rescheduled only twice. A third change requires cancelling and booking fresh. Cancelling more than 24 hours ahead refunds the fee you paid. Cancelling inside 24 hours, or not showing up, forfeits the full fee, though Pearson VUE will waive it for documented personal illness or unforeseen emergency.
How long do I have to wait after passing before I can sit the exam again?
Two years. Once you pass, AWS blocks retaking the same exam for two years. The exception is when AWS publishes an updated version with a new exam guide and a new exam series code, at which point you are eligible for the new version immediately.
Is there an official practice exam?
Yes. AWS publishes a free Official Practice Question Set for DOP-C02 on AWS Skill Builder, and a longer official practice exam plus an Exam Prep Plan behind the paid Skill Builder subscription. AWS also provides a free Exam Demo through Pearson VUE that walks through the exam interface itself, including the flag-for-review and English-toggle controls.
Do I need an associate certification before taking this one?
No. AWS removed prerequisite requirements, and states that all AWS certifications may be earned without completing specific prerequisites. What AWS does recommend is two or more years of hands-on experience provisioning, operating, and managing AWS environments, plus software development lifecycle and scripting experience. Advanced networking, deep database optimization, and full-stack application development are explicitly listed as out of scope for the target candidate.
