Passed EX280 OpenShift Administration

Kick-starting the new year with OpenShift.

EX280 Exam Experience

I took an individual exam that was based on OpenShift 3.9.

It was, hands down, the Red Hat exam I enjoyed the most. The container technology provided by Docker is fascinating, with OpenShift you can go from git push to a running application in a few minutes.

While Ansible-based OpenShift 3 installation is not part of the exam objectives, if you are familiar with Ansible, it will help you during the exam. At least I feel like EX407 experience came in handy.

EX280 is a 3-hour exam, if it was up to me, I’d probably make it a bit longer, simply because there is a lot of documentation available for OpenShift. There are things that I have to look up no matter how often I use them (e.g. limit range object definition), and it takes time.

The exam score 300/300.

Exam Preparation

I took my time with this one and spent several months using Minishift, configuring storage servers and deploying internal registries, building Docker images, testing S2I using simple code and various examples available on GitHub. I also used Kubernetes on AWS.

I’ve done 40+ lab hours on RHLS including the DO180 course.

  1. wow.. 300 … Congrats…!
    Ansible sample exam you posted really helped a lot.
    Can you also post a sample exam for openshift. :)

  2. Hey Tomas

    Big fan of yours here :)
    this is great news, congratulations!!!

    Do you have any special advice for this one, or just practise, practise, practise?
    I also enrolled for EX280 but then I got scared so did not pick a date yet. Instead I scheduled EX342 and hoping for the best..

    Do you have any other exam on your list?
    I’ve been following this website for a while and have to say you did a fantastic job passing all those exams.

    All the best!

    • Thanks very much Karol. You can deploy Minishift locally with some shared storage and Docker registry, then use it as a playground. That’s what I did basically, and I learnt a lot. Don’t try to memorise things, but rather know how to export existing OpenShift resources. You can then use them as a template.

      I do have one other Red Hat exam on my list, however, I’ve not booked it yet.

    • If you know where to find examples in OpenShift documentation, you will be fine. No need to memorise everything.

    • I don’t plan on taking the exam because I don’t use OpenStack, however, I did some studying using RHLS to get familiar with the technology.

  3. Hi, new to your wonderful blog. Wondering if you can help me decide – if I plan to do both the Openshift and Ansible exams, which would you do first? I’m asking based on difficulty (which is easier) and also what makes sense, in logical sequential order (if one will help with the other). I saw that your wrote that your Ansible experience helped with the Openshift exam; not sure if it’s essential though.
    I also asked about the difficulty because my RHCE will expire by September so really need to take at least 1 of them and pass, if I’m pressed for time. Maybe 1 of the exams would fit both criteria. :) I do think both exams are interesting and seem rewarding. I’m just not very fast with studying for exams. I don’t know if I can finish 1 exam per month. I am leaning towards Openshift but I’m not a developer, though I did just complete the CKAD but not the CKA exam yet. I’m definitely not ready for the CKA.
    Your advice would be much appreciated. Thanks in advance!

    • Hi Albert, thanks for your message. If I were to do the exams again, I would do Ansible first, because it’s less challenging compared to OpenShift. I took the OpenShift v3.x exam, but I don’t think that you need Ansible for OpenShift v4.x (the deployment process has changed).

      If you don’t use OpenShift or Kubernetes on a daily basis, the exam might be a bit difficult to prepare for in one month. There are several bits and pieces that can catch you off guard. And let’s face it – OpenShift is big, it has a lot of moving parts. Having said that, learning Ansible and setting up a homelab for it would be much easier in my opinion. Let me know what you decide!
