Do the labs run in my browser, or do I need a cluster?

They run in your browser. Each lesson opens a sandboxed cluster or Linux host that resets between exercises, so there is nothing to install and nothing to rebuild when you break it.

How are the exercises graded?

Against live system state rather than the command you typed. If you reach the objective a different way, it still passes; if the command looked right but the cluster is wrong, it does not.

Are these official Red Hat or Linux Foundation courses?

No. CertLabs is our own platform and the material is exam preparation. It is not affiliated with Red Hat or the Linux Foundation, and it does not replace their official training.

Can you train a whole team instead?

Yes. We deliver the same material instructor-led, on site or remotely, and usually alongside platform work such as an assessment or a migration.

Labs

Practice exams you sit in a real terminal

We built CertLabs because the gap between reading about a cluster and operating one is where candidates fail. Eight tracks, each graded against live system state rather than the command you typed.

The eight tracks

Linux

Kubernetes

OpenShift

AI and agentic engineering

We teach these instructor-led rather than as self-paced tracks, because the useful part is arguing about where an agent should and should not be allowed to act — which needs a room, not a terminal.

What every track includes

Live environments: Sandboxed clusters and Linux hosts that reset between exercises.
Graded labs: Objective checks against real system state, not the command you typed.
Mock exams: Timed and graded, in the real exam format for every track.
Streaks and XP: Daily streaks and levels, to keep momentum without the noise.

CertLabs is our own platform. It is preparation material and is not affiliated with Red Hat or the Linux Foundation.
