Simulate the real AWS Certified DevOps Engineer Professional DOP-C02 exam with full-length timed sessions. Questions drawn proportionally from all 6 official blueprint domains — the same mix you'll face on test day.
Simulate real exam conditions
For the most realistic DOP-C02 simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (180 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
This free DOP-C02 mock exam uses the same question distribution as the real AWS Certified DevOps Engineer Professional DOP-C02 exam. Each session draws questions proportionally from all 6 official blueprint domains published by Amazon Web Services, so the topic mix you see accurately reflects what you'll face on test day.
DOP-C02 Domain Distribution
Configuration Management and IaC
Resilient Cloud Solutions
Incident and Event Response
Monitoring and Logging
Security and Compliance
SDLC Automation
Every question is checked against the 2026 DOP-C02exam objectives and published under the editorial oversight of an engineer with 12+ years' experience. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your DOP-C02 study plan.
Practice test — for learning
Use the DOP-C02 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the DOP-C02 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

A DevOps team uses AWS CodePipeline to automate deployments. The pipeline has a Deploy stage that uses AWS CloudFormation to create or update a stack. Recently, a stack update failed because the template referenced an AMI that was deprecated. The team wants to automatically roll back the stack to the last known good state if a deployment fails. What should they do?

A company uses a third-party backup solution to back up its EC2 instances daily. The backups are stored in an S3 bucket with default settings. The company wants to ensure that backups are protected from accidental deletion and are available for at least one year. Which combination of S3 features should the DevOps engineer implement?

A company uses an Auto Scaling group with a dynamic scaling policy based on a custom CloudWatch metric. After a recent deployment, the metric spikes unexpectedly, causing the Auto Scaling group to launch several EC2 instances. The operations team wants to quickly determine whether the spike was caused by a real load increase or a deployment issue. What is the MOST efficient way to investigate this?

A company runs a critical application on Amazon ECS with Fargate launch type. The application uses an Application Load Balancer (ALB) in front. During a load test, the team notices a sudden increase in 5xx errors from the ALB, and some tasks become unhealthy. The task logs show occasional 'OutOfMemoryError' exceptions. The task definition currently has 512 CPU units and 1024 MiB memory. What should the team do to mitigate the issue while maintaining a cost-effective approach?

A company is running a critical web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The DevOps team wants to monitor HTTP 5xx errors and receive alerts when the error rate exceeds 5% over a 5-minute period. Which combination of services and configurations should be used to meet these requirements?

A company uses AWS CodePipeline with multiple stages: Source (Amazon S3), Build (AWS CodeBuild), and Deploy (AWS CodeDeploy). The build stage runs a series of tests, and if they pass, the pipeline proceeds to deploy. Recently, a developer committed a change that passed all tests but caused a production outage. The team wants to add an approval step before the deploy stage, but they also want to ensure that only changes from specific branches can be deployed. What is the MOST secure and maintainable way to enforce this?
Select an answer to reveal the explanation
A company uses AWS CodeCommit for source control. Developers frequently push large binary files (e.g., compiled JARs) to the repository, causing the repository size to grow rapidly and slowing down clone operations. The team wants to enforce a policy to reject pushes that contain files larger than 50 MB. Which approach should be used?

Answer all 13 questions to see your domain score breakdown
Sitting the DOP-C02 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The DOP-C02 exam lasts 180 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most DOP-C02 distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Amazon Web Services writes many DOP-C02 questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real DOP-C02 is a mental marathon lasting 180 minutes. In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina. If you cannot stay focused for 180 minutes in practice, you will struggle on exam day.

Scaled scoring
The DOP-C02 uses scaled scoring — your raw percentage correct is converted to a score out of 1000. Consistently scoring above 80% on mock exams puts you well above the 750/1000 threshold, giving you a buffer for any unexpected question types on the real exam.
Yes. Courseiva provides free DOP-C02 mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
Aim for consistent scores of 80% or above on full-length DOP-C02 mock exams before booking your test date. The official passing score of 750/1000 corresponds to roughly 72–75% correct answers, so an 80% buffer accounts for difficulty variation and question styles on the real exam.
Most candidates who pass DOP-C02 on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
No — all Courseiva questions are original, AI-assisted and checked against the public Amazon Web Services exam blueprints, with editorial oversight from an experienced network and security engineer.
