Question#1

SIMULATION
Task 11
Create Service Account in QED
Task information Details:
Switch to project qed.
Create service account project1-sa.
Grant the anyuid SCC to that service account.

A. 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.

Question#2

SIMULATION
Task 4
Create Resource Quota for Project Rocky
Task information Details:
Use project rocky and create a quota named rocky-quota with limits for CPU, memory, pods, services, replication controllers, and secrets.

A. 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, replication controllers=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.

Question#3

SIMULATION
Task 7
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.

A. 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.

Question#4

SIMULATION
Scale an application manually
Manually scale the minion application in the gru project to a total of 5 replicas.

A. Solution:
$ oc project gru
$ oc get pods
$ oc get all | grep deployment
$ oc scale --replicas=5 deployment.apps/minion
$ oc get pods
