Studying and passing the AWS DevOps Engineer Pro exam

If the exam had been called, "AWS Solutions Architect - DevOps Professional", I feel that would have been closer to what's in the exam. The 80 questions were all mini-scenarios requiring a "solution". In the exam blueprint, one of the bullet-points in "General IT Knowledge" was

Multi-tier architectures: load balancers, caching, web servers, application servers, databases, and networking

and these formed the basis of most scenarios, so ensure that you are comfortable with multi-tier architectures, particularly load balancers, database back-ends, what can be cached.

The exam itself #

I'd taken all three AWS associate exams at the same test centre, and knew that the computers were typically set to a high resolution, on large monitors, which meant that the questions and answers huddled at the very top of the screen. I knew to expect there to be a great deal of reading in the DevOps Pro exam, so I asked whether it would be possible to have a "retro" resolution of something like 1360x768, and they were very helpful and adjusted it. The scenarios are long (often two or three paragraphs) but even with up to 7 answers to choose from, the text still fitted onto the screen and I didn't need to scroll. It's a lot of reading, so be kind to your eyes!

Video-based learning #

I found myself being very grateful that I'd watched (DVO401) Deep Dive into Blue/Green Deployments on AWS from re:Invent 2015. This gave a very useful framework throughout the exam to think what kind of deployment was best suited to each scenario.

Rohini Gaonkar's article (and extensive list of links) was very helpful.

The books listed here are all good background reading in the wider DevOps context.

Summary #

The AWS DevOps Engineer Pro exam is a hard exam, and the best preparation is lots of hands-on practice with the AWS tools and services, industry experience, and understanding how software is developed, and how it can be quickly deployed, re-deployed, scaled, and rolled back. The resources listed above will help you, but there are probably no short-cuts. Good luck!
