Try 3 DevOps Engineer - Professional (DOP-C02) practice questions
Choose an answer, explore the explanation, and see why the other options are less suitable. Three short scenarios. No sign-in required.
1. Limiting risk during an ECS production release
A team deploys an Amazon ECS service behind an Application Load Balancer. A new task set should receive only a small percentage of production traffic first, and the release must automatically return to the last known good version if a CloudWatch error-rate alarm enters ALARM. Which approach best meets the requirement?
Answer and full explanation
Correct answer: B — Use CodeDeploy blue/green with canary traffic shifting and alarm-driven rollback.
Why B is correct
CodeDeploy supports blue/green deployments for Amazon ECS and can shift traffic to the replacement task set using a canary pattern. That lets the team expose only a small portion of production traffic before routing the remainder. A deployment group can monitor CloudWatch alarms and stop a deployment when an alarm threshold is breached. When automatic rollback is configured, CodeDeploy can return traffic to the last known good revision after a deployment failure or alarm condition. DOP-C02 Task Statement 1.4 explicitly includes blue/green and canary deployment methods for container environments.
Why the other options are less suitable
- A — Rolling deployment and manual review: A rolling deployment gradually replaces tasks, but the proposed process waits for manual inspection and does not provide the requested automatic alarm-driven rollback. It also does not use the explicit canary traffic split required by the scenario.
- C — Immediate full traffic shift: Sending all traffic to the new task set removes the limited-exposure safeguard. A defect could affect the entire production workload before operators can react.
- D — CloudFormation drift detection: Drift detection identifies differences between deployed resources and their template definitions. It does not monitor application error-rate alarms or perform canary traffic shifting for an ECS release.
Key takeaway: For controlled ECS releases, combine blue/green traffic shifting with CloudWatch alarms and automatic rollback.

2. Deploying a baseline across an AWS organization
A company must deploy the same CloudFormation security baseline to every account in a specific AWS Organizations OU across two Regions. New accounts added to the OU must receive the baseline automatically without creating cross-account IAM roles manually. Which solution best meets the requirement?
Answer and full explanation
Correct answer: C — Use service-managed CloudFormation StackSets with OU targeting and automatic deployment.
Why C is correct
CloudFormation StackSets can provision the same template across multiple AWS accounts and Regions from a centralized definition. With service-managed permissions and AWS Organizations integration, CloudFormation creates the required IAM roles in member accounts instead of requiring administrators to create them manually. The StackSet can target a specific OU and deploy stack instances in the selected Regions. Automatic deployment ensures that accounts added to the target OU later receive the stack automatically. DOP-C02 Task Statement 2.1 explicitly includes applying CloudFormation StackSets across multiple accounts and AWS Regions.
Why the other options are less suitable
- A — Independent stacks: Separate manually maintained stacks increase administrative effort and make consistent lifecycle management harder. They also do not automatically onboard future accounts added to the OU.
- B — Self-managed StackSets: Self-managed StackSets can deploy across accounts, but they require the appropriate administrator and execution roles to be created and managed. The scenario explicitly asks to avoid manually creating those cross-account roles.
- D — S3 plus EventBridge: Storing a template in S3 does not itself provide centralized cross-account CloudFormation deployment. A scheduled event in the management account also does not automatically establish the required permissions and OU targeting.
Key takeaway: Service-managed StackSets plus Organizations are built for centrally managed multi-account, multi-Region infrastructure baselines.
3. Automatically remediating a noncompliant security group
An AWS Config rule identifies security groups that allow SSH from 0.0.0.0/0. The DevOps team wants the unwanted ingress rule removed automatically whenever a resource becomes noncompliant, using a repeatable remediation workflow. Which approach best meets the requirement?
Answer and full explanation
Correct answer: A — Use AWS Config automatic remediation with Systems Manager Automation.
Why A is correct
AWS Config can associate a remediation action with a rule and automatically invoke it when a resource is evaluated as noncompliant. AWS Config remediation uses Systems Manager Automation documents to define the corrective actions that should run against the affected resource. A suitable managed or custom automation document can revoke the unwanted security-group ingress rule. DOP-C02 Task Statement 5.2 specifically includes applying configuration changes and remediating an undesired system state in response to events. This approach creates a repeatable automated control rather than depending on a manual operator response.
Why the other options are less suitable
- B — SNS notification: SNS can notify operators about the noncompliant state, but the proposed workflow still requires a person to edit the security group. It therefore does not meet the automatic-remediation requirement.
- C — CloudWatch dashboard: A dashboard can visualize compliance-related information, but it does not change the security-group configuration. Visibility alone does not remediate the undesired state.
- D — VPC Flow Logs: Flow Logs capture information about network traffic for analysis and troubleshooting. They do not modify security-group rules when a Config rule reports noncompliance.
Key takeaway: Pair AWS Config rules with Systems Manager Automation when compliance findings must trigger deterministic configuration remediation.

- If some objectives are unfamiliar, combine practice questions with hands-on work involving CI/CD, CodeDeploy, CloudFormation, StackSets, Systems Manager, AWS Config, CloudWatch, multi-Region resilience, IAM, Organizations, and automated incident response.
- You will need an internet-connected device, a current web browser, and an ExamsDigest account to use the online practice product; this does not imply offline availability or a separate mobile application.
Know the exam you’re studying for
These details describe AWS’s official DevOps Engineer - Professional (DOP-C02) exam.
What our students say
“The DOP-C02 practice exams helped me identify weak areas in CI/CD, CloudFormation, monitoring, and incident response. The explanations were detailed enough to show why each architecture or automation choice fit the scenario better than the alternatives.”
Kevin Sanderson
✓ Verified Review
“The questions covered a strong mix of deployment strategies, infrastructure as code, resilience, security, and multi-account operations. Reviewing the answers I missed helped me focus on the AWS services and DevOps patterns I still needed to revisit.”
Erica Lowe
✓ Verified Review
“I had already used AWS Skill Builder and other DevOps Professional study resources before trying ExamsDigest. What I liked most was how the explanations compared every option, especially around CodeDeploy, StackSets, AWS Config, and automated remediation.”

Your questions, answered.
Which AWS DevOps exam do these practice questions target?
These questions target AWS Certified DevOps Engineer – Professional DOP-C02, the current exam listed by AWS for this certification as of October 3, 2026. Before purchasing or scheduling, confirm that DOP-C02 appears on your booking because AWS can revise certification blueprints over time. The current official documentation and certification page both identify DOP-C02 as the DevOps Engineer – Professional exam.
Who is DOP-C02 practice intended for?
It is intended for experienced DevOps engineers who provision, operate, and manage distributed AWS systems. AWS recommends two or more years of AWS environment experience plus familiarity with the software development lifecycle, programming or scripting, automated infrastructure, operating systems, modern development and operations processes, and AWS infrastructure security. This Professional-level exam assumes deeper operational and automation experience than an Associate certification.
How should I combine DOP-C02 practice with hands-on study?
Use practice questions alongside the official guide and practical exercises involving CodePipeline, CodeBuild, CodeDeploy, CloudFormation, AWS CDK, StackSets, Systems Manager, AWS Config, CloudWatch, EventBridge, Organizations, IAM, multi-Region architectures, backups, containers, and automated remediation. DOP-C02 emphasizes how services work together at scale, so practicing multi-account automation, deployment failure handling, observability, resiliency, and governance is especially useful.
What should I do when I answer a DOP-C02 question incorrectly?
Use the explanation to identify the design or operational requirement you missed, then return to the matching DOP-C02 task statement. Determine whether the mistake involved pipeline automation, infrastructure as code, resilience, monitoring, incident response, or security. Compare every distractor against the scenario’s scale, automation, availability, and governance requirements instead of memorizing the answer letter. Practice results can reveal gaps but should not be treated as a guaranteed exam prediction.
What question formats appear on the official DOP-C02 exam?
AWS uses multiple-choice and multiple-response items. The current guide states that 65 questions affect the score and 10 additional questions are unscored, with unscored questions not identified during the test. The three preview questions use single-answer multiple choice because that is the interaction supported by this widget, so they do not reproduce official multiple-response questions or establish every format or feature included in the paid ExamsDigest product.
Does completing this practice earn AWS Certified DevOps Engineer - Professional?
No. Completing an ExamsDigest practice product does not award the AWS credential or replace AWS’s official certification process. Practice access, scheduling DOP-C02, taking the exam through AWS’s authorized Pearson VUE testing options, and earning the certification are separate activities. AWS currently states that the resulting AWS Certified DevOps Engineer – Professional credential is valid for three years after it is earned.
30-day conditional refund policy
Eligible requests must be made within 30 calendar days, with no more than 20% of any included simulator completed. The purchase must not already be refunded or under a payment dispute or chargeback. Other provisions apply; mandatory consumer rights remain unaffected.
