Working with manifests showed up as small but tricky tasks like applying strategic merge patches, resolving apiVersion mismatches, and using jsonpatch in a constrained editor. I passed the exam and thanks Pass4Success for providing a good collection of exam questions that let me practice those manifest edits quickly.

I just cleared EX280 and the biggest time sink was writing and fixing YAML under pressure, so I practiced oc apply and oc explain until it felt automatic. Make sure you can spot small manifest errors quickly because they cost minutes fast.

Cluster management questions focused on diagnosing clusteroperators and node readiness, often asking you to resolve failing operators or storage issues under time pressure. I passed the exam after drilling oc adm commands, operator status interpretation, and hands-on cluster recovery scenarios to be comfortable under exam time constraints.

Heads-up the route for exposing non-HTTP SNI applications tripped me up because I underestimated how to configure passthrough and NodePort on the ingress. Practicing raw tcp routes and watching the ingress controller logs helped me fix it quickly.

FYI I sat the RedHat EX280 and found authentication tasks around OAuth clients demand exact resource names, so oc get oauth was a lifesaver.

Also testing with port-forward helped isolate whether it was a service misconfiguration or a cluster network issue.

Interestingly the RBAC tasks can be subtle, you need to double check the namespace scope of rolebindings or your permissions won't apply.

Honestly network policies were confusing at first since the default behavior felt implicit until I added explicit allow rules.

Sometimes operators require validating CSV and subscription resources before expecting them to be available for application installs.
