Free RedHat EX280 Exam Dumps August 2026

Solution:

$ oc new-project apollo

$ oc new-project manhattan

$ oc new-project gemini

$ oc new-project bluebook

$ oc new-project titan

$ oc adm policy add-role-to-user admin armstrong -n apollo

$ oc adm policy add-role-to-user admin armstrong -n gemini

$ oc adm policy add-role-to-user view wozniak -n titan

Solution:

Create the initial HTPasswd file with the first user:

htpasswd -c -B -b /tmp/htpass.txt bob indionce

Add the remaining users:

htpasswd -b /tmp/htpass.txt qwerty catalog

htpasswd -b /tmp/htpass.txt john john123

htpasswd -b /tmp/htpass.txt armstrong natasha123

htpasswd -b /tmp/htpass.txt natasha arthstrong

htpasswd -b /tmp/htpass.txt harry harry123

htpasswd -b /tmp/htpass.txt susan susuan123

Create the secret in openshift-config:

oc create secret generic ex280-secure --from-file=htpasswd=/tmp/htpass.txt -n openshift-config

Edit OAuth and add the HTPasswd identity provider:

oc edit oauth cluster

Use a valid structure like this:

spec:

identityProviders:

- name: ex280-idp-secure

mappingMethod: claim

type: HTPasswd

htpasswd:

fileData:

name: ex280-secure

Save and exit.

Restart OAuth pods:

oc delete pod -n openshift-authentication -l app=oauth-openshift

Verify:

oc get pods -n openshift-authentication

oc get oauth cluster -o yaml

This task validates OpenShift local authentication configuration through HTPasswd and cluster OAuth integration.

Solution:

$ oc project lerna

$ oc get pods

$ oc get all | grep deployment

$ oc autoscale deployment.apps/hydra --max=9 --min=6 --cpu-percent=60

$ oc get hpa

$ oc set resources deployment.apps/hydra --limits=cpu=100m -- requests=cpu=25m

$ oc describe deployment.apps/hydra | grep Limits -A3

Solution:

Add the repository:

helm repo add do280-repo http://helm.ocp4.example.com/charts

Refresh repositories:

helm repo update

Install the chart:

helm install example-app do280-repo/etherpad

Verify:

helm list

oc get all

Notes:

The uploaded lab text appears to spell the chart name incorrectly as ehterpad.

In practice, use the actual chart name published in the repo. If the lab repo truly contains the typo, follow the repo index result.

This task tests Helm repository management and application deployment.

Solution:

Ensure the project exists and switch to it:

oc new-project rocky

oc project rocky

Create the quota:

oc create quota rocky-quota \

--hard=limits.cpu=2,limits.memory=1Gi,pods=3,services=6,replicationcontrollers=6,secrets=6

Verify:

oc get resourcequota -n rocky

oc describe quota rocky-quota -n rocky

Notes:

The lab text uses cpu=2,memory=1G and secret=6; in real OpenShift usage, the more reliable forms are limits.cpu, limits.memory, and secrets.

If the exam specifically expects the exact resource names shown in the lab environment, use what the cluster accepts.

This task checks quota enforcement and namespace resource governance.
