NEW QUESTION # 18
Create a CronJob test-cron
Task information Details:
Create service account jupiter .
Grant anyuid SCC and cluster- admin to it.
Update CronJob cron-test to use that service account.
Answer:
Explanation:
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.

NEW QUESTION # 20
Autoscale of Pods
Task information Details:
Create an HPA for httpd with min=2 , max=9 , and CPU target 60% .
Set resource requests on the httpd deployment so autoscaling can function properly.
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
Solution:
* Set resource requests on the deployment:
oc set resources deployment httpd --requests=cpu=50m,memory=100Mi
* Create the HPA:
oc autoscale deployment httpd --min=2 --max=9 --cpu-percent=60
* Verify:
oc get hpa
oc describe hpa httpd
oc get deployment httpd -o yaml
Why resource requests matter:
* HPA CPU utilization is calculated against requested CPU.
* Without requests, percentage-based autoscaling is incomplete or invalid.
This task focuses on autoscaling prerequisites and policy creation.
