AWS DevOps Pro Certification Blog Post Series

This is the start of a blog post series about studying for the AWS DevOps Professional certification.


First a bit of background about me, I'm an engineer at Made Tech who specialises in Site Reliability Engineering. My job is to support our fellow software engineers on two of the three big cloud providers: AWS and Azure. I'm responsible for provisioning the infrastructure that the applications run on, setting up continuous delivery pipelines and application monitoring.

This year I decided I want to strengthen my capabilities with AWS and a good way to do this is to become certified as an AWS DevOps Professional.

My tried and tested method for learning stuff, is to blog about it which is why I'm creating this blog post series! Also, I'm accountable for my study by journaling the experience.


Before we begin, let's be clear about which version of the exam we're referring to. This is the certification exam taken after February 2019.

The AWS DevOps Professional certification costs 300 USD and takes 170 minutes to complete, with a scoring system of 100-1000 points: you need 750 points to pass.

In this version of the exam, they no longer provide the number of questions, but previously it was 80 questions so this works out about 2 minutes per question.

The questions in the exam are information dense. There are two twos of question format:

If you're wondering how dense, take a look at the free sample exam questions (can't provide an example because it's copyrighted material).

Go have a look, and come back when you've done it, I'll wait.

Unless you're already a DevOps Pro or used AWS for a really long time you're probably in a state a shock.

Whilst we wait for the shock subside, let's cover the areas you'll be tested on.

The master of your domain

There are six domains of study, this is the high-level view and we'll go into greater detail in the following posts as part of the series.

DomainSubject% of exam
1Software Delivery Lifecycle (SDLC) Automation22
2Configuration Management and Infrastructure as Code19
3Monitoring and Logging15
4Policies and Standards Automation10
5Incident and Event Response18
6High Availability, Fault Tolerance, and Disaster Recovery16


Luckily there's a variety of resources to help you study.

Your first port of call should be the exam guide aka the blueprint. This guide will give you a list of whitepapers to ready. A detailed breakdown of the topics you're expected to know for each domain (see the table from the previous section).

You've already seen the sample exam questions.

The Exam Readiness Training is another helpful resource with more sample questions.

Knowing when it's time to sit the exam

I didn't feel particularly confident I would pass the exam cold i.e. no study. The exam costs 350 USD, so I wasn't eager to spend that much money (even if it is covered by my employers) to fail.

The next best thing was to try the practice the exam which costs 40 USD which has 20 questions you need to answer within an hour. The practice exam is booked through the AWS Certification site. This is the same method for booking the actual exam, except you can take the practice exam online, whereas the actual exam requires you to visit a test centre.

I sat the practice exam and scored 40% :(

My study plan is to:

I'm tentatively giving myself a month to study, spending at minimum two hours a day. After which I'm going to retake the practice exam if I score at least 80% I'll consider booking the exam.

So stay tuned.
