To clear the AWS certified DevOps engineer professional exam, you need to have in-depth knowledge of AWS services. These exams focus heavily on real world scenarios to apply the latest best practices. 

Below are the core technical areas and what you should understand in each:

1. CI/CD on AWS

Continuous Integration and Continuous Delivery is one of the central themes in the exam, you should study about: 

• Designing and implementing CI/CD pipelines using:
  • AWS CodePipeline
  • AWS CodeBuild
  • AWS CodeDeploy
  • Git-based workflows
• Integrating automated testing, manual approvals, and rollback mechanisms
• Blue/green deployments and canary releases
• CI/CD for containerized and serverless applications (e.g., ECS, Lambda)

2. Infrastructure as Code (IaC)

Infrastructure as Code is another important topic so cover the following: 

• Managing and creating AWS CloudFormation templates
• Using Terraform and other third-party tools
• Automating provisioning of VPCs, EC2, IAM roles, and other such resources
• Stack updates, rollback strategies
• Configuration management for AWS System Manager Parameters Store 

3. Monitoring & Logging

You need to show that you can easily monitor and observe systems using tools and best practices. Ideally focus on: 

• Tools like Amazon CloudWatch for logs and other metrics
• Centralizing logs with AWS CloudTrail, Config, and S3 log aggregation
• Integrating AWS X-Ray for distributed tracing 
• Troubleshooting issues with logs 
• Creating mechanisms for automated replies 

4. Security & Governance

Security and compliance are integrated throughout all the domains of the exam. Focus on:

• Using SCPs, Service Control Policies 
• Setting up AWS Config rules, CloudTrail logs, and auditing changes 

5. Incident & Event Response

You should be able to detect and respond to failures and security issues. Focus on: 

• Setting up the CloudWatch Events, EventBridge, and SNS for automated notifications
• Creating runbooks for manual or automated recovery 
• Implementing regular health checks 
• Planning for disaster recovery 

6. Automation at Scale

You need to learn how to properly automate scaling. You need to work on: 

• Automating tasks using the AWS CLI, SDKs, CloudFormation, or Terraform 
• Using AWS Systems Manage to manage EC2 instances 
• Automation configuration management 
• Implementing auto-scaling
