Exam Overview
The AWS Certified DevOps Engineer – Professional (DOP-C02) is a professional-level credential that validates deep technical expertise in provisioning, operating, and managing distributed systems and services on AWS. It covers the full spectrum of DevOps practices on the AWS platform, including the design and implementation of continuous integration and continuous delivery (CI/CD) pipelines, infrastructure automation using tools like AWS CloudFormation and AWS CDK, and the enforcement of security controls and compliance frameworks across cloud environments. The exam also tests proficiency in building self-healing, highly available, and scalable architectures using AWS-native services such as Auto Scaling, Elastic Load Balancing, and AWS Fault Injection Simulator.
First launched as DOP-C01 and updated to DOP-C02, the current version reflects modern DevOps practices with increased emphasis on resilience engineering, observability, and automated security governance. Candidates must demonstrate competency across six weighted domains: SDLC Automation (22%), Configuration Management and IaC (17%), Security and Compliance (17%), Resilient Cloud Solutions (15%), Monitoring and Logging (15%), and Incident and Event Response (14%). This breadth makes it one of the most comprehensive AWS professional certifications available.
Who Should Take This Exam
This certification is designed for experienced cloud practitioners who actively perform DevOps engineering functions in AWS environments. Ideal candidates include DevOps engineers, cloud platform engineers, site reliability engineers (SREs), and cloud infrastructure architects with at least two years of hands-on experience provisioning, operating, and managing AWS-based systems. Professionals who work on CI/CD pipeline design, infrastructure-as-code authoring, monitoring strategy, and cloud security automation will find the exam objectives directly aligned with their daily responsibilities.
The exam is also well-suited for software developers transitioning into platform or operations roles who have substantial AWS experience and scripting or programming skills. Candidates pursuing senior or lead DevOps positions—particularly in organizations that require formal AWS credentials for cloud infrastructure roles—will find this certification significantly strengthens their professional profile.
Prerequisites
AWS does not enforce formal prerequisites, but strongly recommends that candidates have a minimum of two years of experience provisioning, operating, and managing AWS environments before attempting the exam. A working knowledge of software development lifecycle (SDLC) methodologies, modern development and operations practices, and at least one scripting or programming language (such as Python, Bash, or PowerShell) is expected. Familiarity with Linux/Unix and Windows system administration is also recommended.
While not required, holding an AWS Certified Developer – Associate or AWS Certified SysOps Administrator – Associate credential is a practical stepping stone, as those exams cover foundational AWS services that appear throughout the DOP-C02 domains. Candidates should have hands-on experience with AWS services including CodePipeline, CodeBuild, CodeDeploy, CloudFormation, Systems Manager, CloudWatch, AWS Config, and IAM before sitting for this exam.
Exam Format
The DOP-C02 exam consists of 75 total questions: 65 scored questions that affect the final result and 10 unscored pretest questions that AWS uses for future exam development and are not identified during the exam. Questions are presented in two formats—multiple choice (one correct answer from four options) and multiple response (two or more correct answers from five or more options). The exam is administered over 180 minutes.
Scoring uses a compensatory model on a scale of 100–1,000, with a minimum passing score of 750. This means candidates do not need to achieve a passing threshold in each individual domain; overall performance determines the outcome. Unanswered questions are scored as incorrect, so guessing carries no additional penalty. The exam is delivered through Pearson VUE, either at an authorized testing center or via online proctoring, and is available in English, Japanese, Korean, and Simplified Chinese. The exam fee is $300 USD. AWS certifications remain valid for three years.

Study Tips
- Start with the official AWS Exam Guide for DOP-C02 (available on the AWS Certification page) to map each domain's task statements to specific AWS services, then prioritize hands-on practice with services you have the least experience with.
- Use AWS Skill Builder's official Exam Prep Standard or Enhanced course for DOP-C02, which includes practice question sets aligned to the actual exam domains and structured video content from AWS subject matter experts.
- Build and tear down CI/CD pipelines from scratch using CodePipeline, CodeBuild, and CodeDeploy in a personal AWS account—understanding how these services integrate end-to-end is heavily tested and cannot be learned purely from reading.
- Practice writing CloudFormation templates that include nested stacks, cross-stack references, and custom resources. The Configuration Management and IaC domain (17%) requires deep familiarity with CloudFormation behaviors including rollback triggers and stack policies.
- Take the AWS Certification Official Practice Exam (available on AWS Skill Builder) after completing your study to simulate real exam conditions, identify weak domains, and calibrate your time management for 75 questions in 180 minutes.
- Review AWS whitepapers on DevOps practices, specifically 'Practicing Continuous Integration and Continuous Delivery on AWS' and 'Running Containerized Microservices on AWS,' as exam scenarios frequently draw from these architectural patterns.
- Focus on scenario-based elimination techniques: DOP-C02 questions often present plausible-sounding distractors that include services not suited for the described scale, compliance requirement, or operational constraint. Practice identifying the single best answer rather than a correct-but-suboptimal one.

Preview — answers shown1. A global company uses ECS Fargate for their web platform, CloudFront for distribution, and WAF for security. WAF logs go to 'analytics-waf-logs' CloudWatch Log group. They need alerts for unusual blocked traffic patterns while ignoring other log changes, plus want to fine-tune WAF rules. Alerts should reach the DevOps engineer via SNS. What's the best solution?
AConfigure GuardDuty to monitor WAF logs, trigger CloudWatch alarm for blocked traffic findings sending SNS notifications, use subscription filter policy for relevant alerts only
BConfigure CloudWatch Logs metric filter for blocked requests in the log group creating custom metric, use Anomaly Detection on this metric with alarm for SNS notifications
CCreate CloudWatch anomaly detector for WAF log group, set alarm on LogAnomalyPriority metric with high sensitivity for single anomaly detection, configure SNS notifications
DUse EventBridge to monitor WAF logs in the log group, create rule for blocked request spikes triggering Step Functions workflow for evaluation, notify via SNS
Explanation
CloudWatch Logs metric filters combined with Anomaly Detection provides the ideal solution for detecting unusual patterns in WAF blocked traffic: First, a metric filter extracts specific data from the WAF logs. You define a filter pattern that matches blocked request entries in the log format. For each matching log entry, the filter increments a custom CloudWatch metric. This transforms unstructured log data into quantifiable metrics. CloudWatch Anomaly Detection then analyzes this custom metric using machine learning. It automatically learns the normal patterns of blocked traffic - hourly, daily, and weekly cycles. The ML model adapts to your specific traffic patterns without manual threshold configuration. When blocked traffic deviates significantly from learned patterns, the anomaly detector triggers. You create an alarm on this anomaly detection that sends notifications via SNS when unusual patterns occur. This catches both spikes and drops in blocked traffic that might indicate attacks or misconfigured rules. GuardDuty focuses on AWS account threats, not application-layer WAF events. EventBridge works with discrete events, not pattern analysis over time. LogAnomalyPriority is a generic log anomaly metric not specific to blocked traffic patterns - it would generate many false positives. This solution provides intelligent alerting that adapts to your normal traffic patterns, focusing specifically on blocked requests as required for WAF rule tuning.
2. A financial firm with an AWS Enterprise Support plan wants to automate their response to certain AWS Trusted Advisor checks. For example, if Trusted Advisor reports that an account is approaching a service limit, they want to automatically create a support case to request a limit increase. How can they programmatically access the Trusted Advisor check results to build this automation?
ABy using the AWS Support API, which is available to customers with a Business or Enterprise support plan.
BBy scraping the AWS Management Console for the Trusted Advisor dashboard.
CThis is not possible; Trusted Advisor results are only available in the console.
DBy parsing the weekly email notifications from Trusted Advisor.
Explanation
The key to this question is knowing the prerequisites for programmatic access to Trusted Advisor. Why the AWS Support API approach is correct: The whitepaper explicitly states that customers with AWS Business or Enterprise support can access all Trusted Advisor checks and the Trusted Advisor APIs. The AWS Support API allows you to programmatically interact with AWS Support, which includes refreshing and retrieving the results of Trusted Advisor checks. This API access is what enables the creation of automated remediation workflows. Why other approaches are incorrect: Parsing weekly email notifications is brittle and not a reliable method for automation. Scraping the AWS Management Console is also brittle and not a recommended practice. The claim that API access is impossible is incorrect, as API access is available for customers on higher-tier support plans.
3. A team is designing a highly resilient application using a cell-based architecture. What is a key characteristic of a 'cell' in this architectural pattern?
AIt is a logical grouping of resources based on tags.
BIt represents a single EC2 instance.
CIt is a shared database layer used by all other parts of the system.
DIt is an isolated, independently functioning replica of the entire system or a subset of it, containing its own application logic and data storage.
Explanation
This question tests the definition of a specific, advanced architectural pattern mentioned in the whitepaper. Why this is correct: As described in the 'Advanced deployment strategies' section, a cell-based architecture segments a larger system into isolated, independently functioning replicas called cells. Each cell is a self-contained unit that can serve a portion of the user traffic. This isolation limits the 'blast radius' of a failure; if one cell fails, it does not impact the others. This pattern is used to build highly resilient, scalable systems. Why others are incorrect: Options A, B, and D do not accurately describe the concept of a cell in this context.
4. An online hospital records system runs on a fleet of Windows EC2 instances. A new compliance rule requires that all instances must be patched with the latest security updates and must only be launched from an approved 'golden' AMI. The development team, however, needs the flexibility to launch instances from unapproved AMIs for testing purposes, but any such non-compliant instances must be detected and reported. What combination of AWS services should be used to meet both the patching and AMI compliance requirements?
AUse AWS Systems Manager Patch Manager with a defined patch baseline to handle the automated patching. Use AWS Config with the approved-amis-by-id managed rule to detect and report any EC2 instances launched from unapproved AMIs.
BUse Amazon GuardDuty to continuously monitor for unpatched instances and the use of unapproved AMIs.
CSet up a strict IAM policy that denies the RunInstances action for any AMI that is not on the approved list.
DUse AWS Shield Advanced to protect the instances and automatically detect non-compliant AMIs.
Explanation
This scenario requires two separate but related compliance controls: one for OS patching and one for AMI usage. The best solution uses the specific AWS service designed for each task. For automated OS patching, the correct service is AWS Systems Manager Patch Manager. You can create a patch baseline that defines which patches are approved (e.g., all critical security updates) and then use a Maintenance Window to apply these patches on a schedule. For auditing AMI usage, the correct service is AWS Config. It is designed to continuously monitor the configuration of your AWS resources. You can enable the approved-amis-by-id managed rule, provide it with your list of approved AMI IDs, and it will automatically flag any running EC2 instance that was not launched from one of those AMIs as 'non-compliant'. This provides the required detection and reporting without blocking developers from launching instances, thus meeting all requirements. A strict IAM policy would block the developers, which violates a requirement. GuardDuty and Shield are for threat detection and DDoS protection, respectively; they do not perform this type of configuration compliance checking.
5. During a tense code review meeting at 'CodeCrafters LLC', a disagreement about a design choice escalates, causing a delay in the release. The company wants to implement a mechanism for resolving such disputes constructively, where team members are encouraged to challenge decisions but must commit to the final outcome. Which mechanism, inspired by Toyota and Amazon, does the whitepaper suggest for this purpose?
AThe Two-Pizza Team rule
BThe Working Backwards process
CThe Inverse Conway Maneuver
DThe Andon cord concept
Explanation
This question asks for a specific cultural mechanism for escalating and resolving issues. Why the Andon cord concept is correct: The whitepaper explicitly mentions the Andon cord concept as a way to help team members raise concerns and stop processes when problems arise. It serves as a mechanism for quick escalation to address problems effectively. It fosters a culture where it is safe to raise issues and encourages a structured, data-driven process for resolution, after which the team commits to the decision and moves forward. Why the other approaches are incorrect: The Two-Pizza Team rule is about team size. The Working Backwards process is a product development methodology. The Inverse Conway Maneuver is a principle relating organizational structure to system architecture.
