EX280 Exam Dumps - Red Hat Certified Specialist in OpenShift Administration exam

Solution:

Scale the deployment:

oc scale deployment httpd --replicas=5

Verify:

oc get deployment httpd

oc get pods -l app=httpd

Confirm the desired, current, and available replica counts match.

This task checks direct workload scaling using the OpenShift CLI.

Solution:

Create the groups:

oc adm groups new site-users

oc adm groups new guest-users

Add users to groups:

oc adm groups add-users guest-users qwerty

oc adm groups add-users site-users harry susan

Grant edit role on test to site-users:

oc policy add-role-to-group edit site-users -n test

Grant view role on demo to guest-users:

oc policy add-role-to-group view guest-users -n demo

Verify:

oc get groups

oc describe group site-users

oc describe group guest-users

oc get rolebinding -n test

oc get rolebinding -n demo

This task measures practical administration of OpenShift groups and project-scoped RBAC assignments.

Solution:

$ oc get all | grep deploy

$ oc set env --from=secret/magic deployment.apps/qed

Solution:

Switch to the correct project if needed:

oc project monday

Inject environment variables from the secret:

oc set env deployment/monday --from=secret/magic

Verify:

oc set env deployment/monday --list

oc describe deployment monday

Notes:

The uploaded lab references secret/file-secret, but Task 8 clearly intends the secret to be named magic .

In a real exam, match the actual secret name present in the cluster.

This task tests secret consumption by workloads through environment variable injection.
