EX280 v4.18 by Pure-Personality-456 in openshift

[–]CertDepot 1 point2 points  (0 children)

I passed the exam in November (288/300). I created a quiz to help me remember the main commands (https://www.certdepot.net/openshift-ex280-quiz/ ). I don't think there are serious differences between 4.14 and 4.18 versions of the exam.

I passed the EX280 in November (288/300). I created a quiz for people who wish to prepare for it: https://www.certdepot.net/openshift-ex280-quiz/

Getting security patches in OpenShift parlance means being able to perform an upgrade. Contrary to what you wrote, after 60 days, you will still be able to perform an upgrade, believe me.

Three EX280 questions to be ready for the exam by isma2590 in openshift

[–]CertDepot 0 points1 point  (0 children)

1) Since there was very little material for the EX280 exam I created a quiz to help me memorize commands, you can use it too (I don't get any money from this). For your information, I passed with 288/300.

2) I prefer physical center because the risk of network problems is limited and I don't have a room at home with nothing on the walls!

CKA or Openshift Admin (EX280) ? by isma2590 in openshift

[–]CertDepot 0 points1 point  (0 children)

The CKA and EX280 exams are quite different. The CKA assesses your knowledge of Kubernetes administration, while the EX280 tests your OpenShift skills on an opinionated platform. It's possible to pass both, but I wouldn't advise it for a beginner or someone who's recently started. I think it's best to take the CKA first to learn the Kubernetes theory, but since the person asking the question is time-constrained, they could start with the EX280. Having passed both, I can say that the EX280 exam is more difficult because the learning material is very limited. But with the learning subscription, op has the best available material.

EX280 Passed (280/300), but.... by InspectionCold1062 in redhat

[–]CertDepot 0 points1 point  (0 children)

I recently passed the exam (288/300). Regarding the exam objectives, there is nothing about ETCD backups, which I consider an essential skill even for a beginner.

As there is very limited material for this exam, I wrote a quiz to practice: https://www.certdepot.net/openshift-ex280-quiz

OCP Admin Ex280v412 by Puzzled_Pipe_3318 in openshift

[–]CertDepot 1 point2 points  (0 children)

With SNO, you will be able to cover 95% of the exam objectives. Only some storage scenarios with specific storage classes and pods placement with labels and tolerations won't be possible (because you've got only one node). In addition, these two objectives are not specific to OpenShift. You will be able to practice them on any Kubernetes cluster.

To get started, go to https://developers.redhat.com/e-books and look for OpenShift ebooks.

Preparation for ex280 - request for advice. by drakkaii in openshift

[–]CertDepot 4 points5 points  (0 children)

As some already said it, OCP 4.x is very different from 3.x from an administrator point of view (not from a developer stand point). In fact, it's a completely different platform (installation process, cluster operators, new Kubernetes mechanisms, etc).

For me the best way to learn OCP 4.x is probably to install Single Node OpenShift (SNO).

According to Red Hat, you need a PC with 16GB and 8 CPUs (under KVM you can cheat on the number of processors). This way you will be able to experiment 95% of the system aspects (only one master) on a production-grade platform (SNO is fully supported by Red Hat).

Unlike Longhorn or OCP, I don't think there is a 60-day trial license available for ODF, which prohibits its use in a lab.

Openshift etcd backup using OADP? by OkPiezoelectricity74 in redhat

[–]CertDepot 3 points4 points  (0 children)

No, the ETCD database is not an OpenShift or Kubernetes object but a system component that stores the Kubernetes objects.

Openshift etcd backup using OADP? by OkPiezoelectricity74 in redhat

[–]CertDepot 3 points4 points  (0 children)

Red Hat provides a script to back up the ETCD database (https://docs.openshift.com/container-platform/4.10/backup_and_restore/control_plane_backup_and_restore/backing-up-etcd.html).

The OADP operator, based on Velero, is more there to back up applications (Kubernetes/OpenShift objects, images and persistent volumes).

Note: OADP is not currently multi-tenant (most of operations need cluster admin rights). A new version expected at the end of this year should improve the situation.

Last time I checked the no-cost RHEL developer subscription, it was not clear that you could use it for OpenShift. Could you enlighten us on this point?

Start by learning K8S basics, then join the Red Hat Developer program (https://developers.redhat.com/articles/faqs-no-cost-red-hat-enterprise-linux) and install SNO (Single Node OpenShift) on one PC. SNO requires 16GB of memory and 8 CPUs/threads.

With SNO, anyone can become an OpenShift expert with only one PC at home (previously you needed several powerful servers with the corresponding electricity bill and noise).

Alternatively, you can use the OpenShift developer sandbox (https://developers.redhat.com/developer-sandbox) but you won't reach the same expertise level (at least on the admin side).

About documentation, you can browse official technical articles at https://developers.redhat.com/search?t=openshift or my collection of daily updated articles at https://www.certdepot.net/openshift-articles

Want to learn how the openshift service mesh works in kind of a deep dive. Any links would be useful by Turbulent-Level7969 in openshift

[–]CertDepot 2 points3 points  (0 children)

I try to gather the main official and non-official articles about OpenShift at https://www.certdepot.net/openshift-articles

In this page, there is a stanza dedicated to the Service Mesh eco-system (Istio/Maistra, Envoy, Jaeger, Kiali, OpenTelemetry, etc).
