Use this topic map to guide your study for Amazon DOP-C02 (AWS Certified DevOps Engineer - Professional Exam) within the Amazon Professional path.
The DOP-C02 exam measures both conceptual understanding and applied reasoning through a mix of question types that reflect real DevOps scenarios.
Questions progress in difficulty, requiring you to apply concepts across multiple domains and justify your reasoning in complex, multi-layered scenarios.
Effective preparation involves mapping the six core domains to a structured study schedule, practicing with realistic questions, and building confidence through timed assessments. A typical four-to-six-week plan works well for candidates with foundational AWS experience.

SDLC Automation and Monitoring and Logging typically account for a larger portion of exam questions, reflecting their importance in real DevOps roles. However, all six domains are tested, so balanced preparation across each topic is essential. Prioritize hands-on experience with CI/CD pipelines and observability tools during your study.
Infrastructure as Code enables you to define resilient architectures (multi-region, auto-scaling, load balancing) and replicate them consistently. When you version control your IaC templates, you can quickly roll back or scale up during incidents. Understanding this connection helps you design systems that are both reproducible and fault-tolerant.
Prioritize building a CI/CD pipeline from scratch using AWS CodePipeline and CodeBuild, setting up CloudWatch monitoring and alarms, and deploying infrastructure with CloudFormation or Terraform. Labs involving incident simulation and log analysis are particularly valuable, as they mirror exam scenarios and build practical problem-solving skills.
Many candidates overlook the importance of Security and Compliance in DevOps workflows, underestimate scenario-based questions that require multi-step reasoning, or focus too heavily on memorizing AWS service features without understanding how they integrate. Practice with realistic scenarios and always ask "why" when reviewing answers to avoid these pitfalls.
Shift from learning new content to reinforcing weak areas and building test stamina. Take one full-length practice test under timed conditions, review all incorrect answers, and do targeted drills on domains where you scored below 80 percent. Get adequate sleep the night before; fatigue on exam day costs more points than extra cramming.
A company is using AWS Organizations to create separate AWS accounts for each of its departments The company needs to automate the following tasks
* Update the Linux AMIs with new patches periodically and generate a golden image
* Install a new version to Chef agents in the golden image, is available
* Provide the newly generated AMIs to the department's accounts
Which solution meets these requirements with the LEAST management overhead'?
Amazon EC2 Image Builder is a service that automates the creation, management, and deployment of customized, secure, and up-to-date server images that are pre-installed with software and configuration settings tailored to meet specific IT standards. EC2 Image Builder simplifies the creation and maintenance of golden images, and makes it easy to generate images for multiple platforms, such as Amazon EC2 and on-premises. EC2 Image Builder also integrates with AWS Resource Access Manager, which allows you to share your images across accounts within your organization or with external AWS accounts. This solution meets the requirements of automating the tasks of updating the Linux AMIs, installing the Chef agent, and providing the images to the department's accounts with the least management overhead.

A company uses an AWS CodeCommit repository to store its source code and corresponding unit tests. The company has configured an AWS CodePipeline pipeline that includes an AWS CodeBuild project that runs when code is merged to the main branch of the repository.
The company wants the CodeBuild project to run the unit tests. If the unit tests pass, the CodeBuild project must tag the most recent commit.
How should the company configure the CodeBuild project to meet these requirements?
Step 1: Using Native Git in CodeBuildTo meet the requirement of running unit tests and tagging the most recent commit if the tests pass, the CodeBuild project should be configured to use native Git to clone the CodeCommit repository. Native Git support allows full functionality for managing the repository, including the ability to create and push tags.
Action: Configure the CodeBuild project to use native Git to clone the repository and run the tests.
Why: Using native Git provides flexibility for managing tags and other repository operations after the tests are successfully executed.
Step 2: Tagging the Most Recent CommitOnce the unit tests pass, the CodeBuild project can use native Git to create a tag for the most recent commit and push that tag to the repository. This ensures that the tagged commit is linked to the test results.
Action: Configure the project to use native Git to create and push a tag to the repository if the tests pass.
Why: This ensures the correct commit is tagged automatically, streamlining the workflow.
This corresponds to Option A: Configure the CodeBuild project to use native Git to clone the CodeCommit repository. Configure the project to run the unit tests. Configure the project to use native Git to create a tag and to push the Git tag to the repository if the code passes the unit tests.
A DevOps engineer needs to configure an AWS CodePipeline pipeline that publishes container images to an Amazon Elastic Container Registry (Amazon ECR) repository. The pipeline must wait for the previous run to finish and must run when new Git tags are pushed to a Git repository that is connected to AWS CodeConnections. An existing deployment pipeline needs to run in response to the publication of new container images. Which solution will meet these requirements?
The requirements clearly indicate the need for modern CodePipeline capabilities, strict execution ordering, Git tag--based triggers, and loose coupling between pipelines. CodePipeline V2 introduces execution modes such as QUEUED and SUPERSEDED, along with native support for advanced trigger filtering when using AWS CodeConnections.
The requirement that the pipeline must wait for the previous run to finish directly maps to QUEUED mode, which ensures that pipeline executions run sequentially rather than replacing in-progress executions. SUPERSEDED mode would cancel the running execution, which violates the requirement.
Triggering the pipeline when new Git tags are pushed is supported through CodePipeline V2 trigger filters using refs/tags/*. Branch-based triggers would not satisfy this condition.
Finally, the requirement that an existing deployment pipeline runs in response to new container images is best met using Amazon EventBridge, which natively emits events for ECR image push actions. EventBridge allows decoupled, event-driven orchestration between pipelines without tight dependencies or custom scripting. This is the AWS-recommended approach for pipeline-to-pipeline coordination.
Options C and D rely on CodePipeline V1, which lacks modern trigger filtering and execution control. Option B incorrectly uses SUPERSEDED mode and branch-based triggers.
Therefore, Option A correctly combines CodePipeline V2, QUEUED execution mode, tag-based triggers, and EventBridge-driven pipeline chaining, meeting all requirements with best practices and minimal operational complexity.
A company has a data ingestion application that runs across multiple AWS accounts. The accounts are in an organization in AWS Organizations. The company needs to monitor the application and consolidate access to the application. Currently the company is running the application on Amazon EC2 instances from several Auto Scaling groups. The EC2 instances have no access to the internet because the data is sensitive Engineers have deployed the necessary VPC endpoints. The EC2 instances run a custom AMI that is built specifically tor the application.
To maintain and troubleshoot the application, system administrators need the ability to log in to the EC2 instances. This access must be automated and controlled centrally. The company's security team must receive a notification whenever the instances are accessed.
Which solution will meet these requirements?
Even if AmazonSSMManagedlnstanceCore is a managed policy and not an IAM role I will go with C because this policy is to be attached to an IAM role for EC2 to access System Manager.
A development team is using AWS CodeCommit to version control application code and AWS CodePipeline to orchestrate software deployments. The team has decided to use a remote main branch as the trigger for the pipeline to integrate code changes. A developer has pushed code changes to the CodeCommit repository, but noticed that the pipeline had no reaction, even after 10 minutes.
Which of the following actions should be taken to troubleshoot this issue?
When you create a pipeline from CodePipeline during the step-by-step it creates a CloudWatch Event rule for a given branch and repo
like this:
{
'source': [
'aws.codecommit'
],
'detail-type': [
'CodeCommit Repository State Change'
],
'resources': [
'arn:aws:codecommit:us-east-1:xxxxx:repo-name'
],
'detail': {
'event': [
'referenceCreated',
'referenceUpdated'
],
'referenceType': [
'branch'
],
'referenceName': [
'master'
]
}
