1. Understand the Exam Blueprint Thoroughly

Start by familiarizing yourself with the AWS exam guide. It breaks down the six domains covered in the exam:

• SDLC Automation

• Configuration Management and Infrastructure as Code

• Monitoring and Logging

• Policies and Standards Automation

• Incident and Event Response

• High Availability, Fault Tolerance, and Disaster Recovery

Understanding what each domain entails helps you prioritize your study plan based on weightage.

2. Get Hands-On Experience

This certification is not theoretical—real-world experience is crucial. You should have at least 2 years of hands-on experience with AWS services such as:

• AWS CodePipeline, CodeDeploy, CodeBuild

• CloudFormation, Terraform (optional but helpful)

• CloudWatch, X-Ray, and CloudTrail

• EC2, ECS, Lambda, and Auto Scaling

• IAM, KMS, and security best practices

If you’re missing experience in any of these, create practice projects in a free-tier AWS account to get comfortable.

3. Use High-Quality Learning Resources

Invest in reliable and up-to-date resources, such as:

• AWS Training & Certification official courses

• A Cloud Guru or Whizlabs

• Stephane Maarek’s DevOps Professional course on Udemy

• Tutorials Dojo practice tests for realistic exam scenarios

These materials often mirror the style and complexity of actual questions.

4. Master Infrastructure as Code (IaC)

Infrastructure as Code is a major focus in the exam. You must understand:

• How to create and manage CloudFormation templates

• Best practices for modularization, parameterization, and change sets

• Automating infrastructure deployment using IaC tools

Being confident in this area can significantly boost your score.

5. Embrace DevOps Principles

The exam evaluates your understanding of DevOps culture just as much as AWS services. Ensure you're familiar with:

• CI/CD pipelines and deployment strategies (blue/green, canary)

• Monitoring and observability

• Feedback loops and automation

• Compliance and security automation

Use case studies or whitepapers from AWS to understand how these principles are applied in real AWS environments.

6. Practice with Timed Mock Exams

Taking full-length practice exams under timed conditions is essential. It helps:

• Improve your time management

• Identify weak areas

• Reduce anxiety during the actual exam

Aim for at least 75-80% consistently before scheduling the real exam.

7. Review AWS Whitepapers and FAQs

AWS whitepapers such as the Well-Architected Framework and the Security Best Practices are often referenced indirectly in the exam. Also, study FAQs of key services, as they contain insights not always found in documentation or courses.

8. Use the AWS Free Tier for Practice

Hands-on experimentation is best done in the AWS Free Tier. Set up CI/CD pipelines, deploy sample applications, and simulate real-world workflows. This helps reinforce theoretical knowledge with practical understanding.

9. Join a Community

Participating in AWS communities, forums, and study groups (like on Reddit, Discord, or LinkedIn) allows you to:

• Learn from others' experiences

• Clarify doubts quickly

• Stay motivated through accountability

Others may even share recent exam trends and question styles.

10. Stay Calm and Confident on Exam Day

Before your exam:

• Get a good night’s sleep

• Arrive early or prepare your system if taking it online

• Read each question carefully—look for keywords and qualifiers like "most cost-effective" or "high availability"

If unsure of an answer, mark it for review and move on—don’t let one question eat into your time.
