Ex280 - how to answer yaml questions faster?

[fathiyyah1]

Hello guys

I'm studying for the Ex280 exam, and I feel yaml questions will take my time, and I want to know how to solve them faster?

I can use a GUI web, but I don't know how to take the steps there because I can't practice. I don't have the budget to subscribe to Red Hat.

@fathiyyah1 practice , practice and practice. Familiarize yourself with the various resource types and practice enough so that you can not only write those yamls but also you can export a resource and edit it.

@fathiyyah1 Totally feel you on the yaml time crunch during EX280, It can definitely eat into your exam window if you're not prepped.

A couple of tips that could help:

Try oc create --dry-run=client -o yaml to generate yaml from cli. It saves time and helps avoid syntax errors. You can tweak the output as needed and apply it directly.

For practice, CodeReady Containers (CRC) might be worth a look if your machine can handle it. It gives you a full local OpenShift cluster (CLI + GUI).

There's also the Red Hat Developer Openshift Sandbox, free for 30 days. It’s cloud-based and useful for practice, though some admin features are limited since you don't get full cluster access.

@fathiyyah1, if you have VMware or Nutanix infra, you can deploy SNO (Single Node Openshift) for practice, it is best way to do it, or also if you are having system with good spec like more than 16GB memory then also you can deploy it within VMware worksstation. SNO is best way for practice.
There are various ways for SNO deployment on any infra, you needs to figure out which is best for you

To answer YAML questions faster in the EX280 exam, focus on mastering OpenShift YAML syntax, utilizing oc explain effectively, and practicing with real-world scenarios. Familiarize yourself with common OpenShift resource types (Deployments, Services, Routes, etc.) and their corresponding YAML fields. Time management and troubleshooting skills are also crucial for completing the exam within the allotted time.
