We kept getting feedback that our first DOP-C02 set read like it was written for the Associate exam. It was. We scrapped it and rewrote all 50 questions around actual operational failure modes.
When you sit the real DevOps Professional exam, AWS doesn't ask you what AWS Systems Manager does — they give you a scenario where a deployment stalled mid-canary on an ECS cluster with target groups failing health checks across two availability zones, and you have 90 seconds to determine the least disruptive rollback path.
That's the standard we hold all CBTs to.

BuildRoulette started with a simple observation: there are a lot of places to learn cloud, but knowing something and being able to build, troubleshoot, and make decisions with it are two completely different things.
Built by Oyinkansola — less memorization, more doing; less “here's what this service does,” more “here's a problem, figure it out.”
Build something. Break something. Figure it out.
