EX280 무료 덤프문제 온라인 액세스

See the solution below in Explanation.
Explanation:
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.

See the solution below in Explanation.
Explanation:
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.

Explanation:
Solution:
* Create the projects:
oc new-project apollo
oc new-project test
oc new-project demo
* Grant cluster-admin to bob:
oc adm policy add-cluster-role-to-user cluster-admin bob
* Disable normal self-provisioning for authenticated users:
oc adm policy remove-cluster-role-from-group self-provisioner system:authenticated:oauth
* Allow john to self-provision:
oc adm policy add-cluster-role-to-user self-provisioner john
* Give natasha view access in test and apollo:
oc policy add-role-to-user view natasha -n test
oc policy add-role-to-user view natasha -n apollo
* Give armstrong admin in apollo:
oc policy add-role-to-user admin armstrong -n apollo
* Remove kubeadmin secret:
oc delete secret kubeadmin -n kube-system
* Verify permissions:
oc adm policy who-can create projectrequests
oc describe rolebinding.rbac -n apollo
oc describe rolebinding.rbac -n test
This task tests core OpenShift administration around project lifecycle control, cluster-level RBAC, and decommissioning default bootstrap credentials.

See the solution below in Explanation.
Explanation:
Solution:
* Switch to the project hosting the cronjob, if needed:
oc project cron-test
* Create the service account:
oc create sa jupiter
* Grant anyuid:
oc adm policy add-scc-to-user anyuid -z jupiter -n cron-test
* Grant cluster-admin:
oc adm policy add-cluster-role-to-user cluster-admin system:serviceaccount:cron-test:jupiter
* Update the cronjob:
oc patch cronjob cron-test -p '{"spec":{"jobTemplate":{"spec":{"template":{"spec":{"serviceAccountName":" jupiter"}}}}}}'
* Verify:
oc get cronjob cron-test -o yaml | grep serviceAccountName
Notes:
* The uploaded lab uses oc set sa cronjob.batch/cron-test jupiter, which is not the usual command form for CronJobs. Patching the pod template is the reliable method.
This task checks service account and privilege adjustments for scheduled workloads.

See the solution below in Explanation.
Explanation:
Solution:
* Switch to the project:
oc project qed
* Create the service account:
oc create serviceaccount project1-sa -n qed
* Grant the SCC:
oc adm policy add-scc-to-user anyuid -z project1-sa -n qed
* Verify:
oc get sa project1-sa -n qed
oc adm policy who-can use scc anyuid
Why this matters:
* anyuid allows containers to run with arbitrary user IDs when an application requires it.
* This is a common administrative task in OpenShift for third-party container images.
This task validates service account creation and SCC assignment.
