My preparation for AWS Certified DevOps Engineer — Professional exam

I completed my AWS Certified DevOps Engineer — Professional Certification exam with 936 score last week. I will say it is one of the most challenging and requires a lot of in-depth knowledge about integrating AWS services and automating everything. I thought it would be useful to share my experience, learning material and few observations from the exam. Hopefully, it will help someone who is preparing for the exam.

To start, I will say, take a good AWS DevOps Professional courses (Stéphane Mark is my favorite) to build your foundation strong. Also, Practice exams are a must. As they say, “Practice makes perfect”. At least for me it always works. Good to have Hand-On experience or On-Job Experience. I will suggest, to do lots of practice with suggested labs in the course and you can try practicing questions yourself on the AWS platform with a free account. Below is the list of online courses and practice exams I used for my preparation.

1- AWS Certified DevOps Engineer Professional 2020 — Hands On!

https://www.udemy.com/course/aws-certified-devops-engineer-professional-hands-on/

2- Acloudguru course

3- Practice Exam | AWS Certified DevOps Engineer Professional

https://www.udemy.com/course/aws-certified-devops-engineer-professional-practice-exam-dop/

4- AWS Certified DevOps Engineer Professional

https://www.whizlabs.com/aws-devops-certification-training/practice-tests/

5- AWS Certified DevOps Engineer Professional Practice Exams 2020

https://portal.tutorialsdojo.com/courses/aws-certified-devops-engineer-professional-practice-exams/

Some Tips:

1- Topics which in my opinion will cover lots of questions in exams are:

SSM parameter stores, secrets manager, KMS to decrypt/encrypt secrets, ECS, ECR, Beanstalk, Code pipeline, AWS CloudFormation, Cloud watch events, AWS config, Lambda, Kinesis, AWS Organizations (got couple of questions)

2- Most of the questions combine a couple of different AWS services and test your knowledge on how services can be integrated. Always look for combinations like

AWS KMS + Systems Manager Parameter Store + hybrid automation

Cloud watch events and lambda for automation.

Invoke an AWS Lambda Function in a Pipeline in CodePipeline

3- AWS blogs are the best resource for preparation. You will find that many of the questions are based on AWS blogs.

4- AWS Exam guide from below link will be a great place to start and follow along while preparing.

Introduction to DevOps on AWS — Great read

AWS Certified DevOps Engineer — Professional (DOP-001) Sample Exam Questions

Useful reading:

“Stephane Maarek” has given a list of the readings on his course. I took the same and updated these listed with additional AWS blogs and articles for each domain which I found useful. I know this list seems a lot, but this exam really needs and lot of reading and practical experience. So enjoy the readings and Best of luck :)
