AWS Certified DevOps Engineer – Professional (DOP-C01) Exam Learning Path

NOTE – Refer to DOP-C02 Learning Path

AWS Certified DevOps Engineer – Professional (DOP-C01) exam is the upgraded pattern of the DevOps Engineer – Professional exam which was released last year (2018). I recently attempted the latest pattern and AWS has done quite good in improving it further, as compared to the old one, to include more DevOps related questions and services.

AWS Certified DevOps Engineer – Professional (DOP-C01) exam basically validates

  • Implement and manage continuous delivery systems and methodologies on AWS
  • Implement and automate security controls, governance processes, and compliance validation
  • Define and deploy monitoring, metrics, and logging systems on AWS
  • Implement systems that are highly available, scalable, and self-healing on the AWS platform
  • Design, manage, and maintain tools to automate operational processes

AWS Certified DevOps Engineer – Professional (DOP-C01) Exam Summary

  • AWS Certified DevOps Engineer – Professional exam was for a total of 170 minutes but it had 75 questions (I was always assuming it to be 65) and I just managed to complete the exam with 20 mins remaining. So be sure you are prepared and manage your time well. As always, mark the questions for review and move on and come back to them after you are done with all.
  • One of the key tactic I followed when solving the DevOps Engineer questions was to read the question and use paper and pencil to draw a rough architecture and focus on the areas that you need to improve. Trust me, you will be able eliminate 2 answers for sure and then need to focus on only the other two. Read the other 2 answers to check the difference area and that would help you reach to the right answer or atleast have a 50% chance of getting it right.
