RedHat Red Hat Certified Specialist in OpenShift Advanced Cluster Management 認定 EX432 試験問題 (Q33-Q38):

質問 # 33
Detach (unimport) a managed cluster safely from the hub

正解：

解説：
See the solution below in Explanation.
Explanation:
* Identify the managed cluster:
oc get managedcluster
* If required in your environment, remove dependent placements/policies/apps targeting it (exam often expects you to check "why deletion stuck").
* Delete managed cluster:
oc delete managedcluster cluster-dev
* Watch finalizers and cleanup:
oc get managedcluster cluster-dev -o yaml | grep finalizers -n
Why this matters:
Proper lifecycle operations (import/manage/detach) is core EX432/EX480 scope.


質問 # 34
Switch a policy from enforce # inform (report-only) and validate behavior

正解：

解説：
See the solution below in Explanation.
Explanation:
* Patch remediation to inform:
oc patch policy policy-ensure-audit-namespace -n team-dev --type=merge -p '{"spec":{"remediationAction":" inform"}}'
* Verify:
oc get policy policy-ensure-audit-namespace -n team-dev -o yaml | grep remediationAction -n
* Observe compliance changes (policy will report but not auto-fix).


質問 # 35
Set TimeWindow for App (Web Console)
Task information: Add timeWindow to Subscription spec (active window Friday 09:00-17:00)

正解：

解説：
See the solution below in Explanation.
Explanation:
* In ACM console go to Applications .
* Select the application you deployed.
* Open the Editor view (YAML editor) for the Subscription object.
* Under spec, add a timeWindow section similar to what the lab requests:
* windowtype: active
* day: Friday
* hours: 09:00-17:00
* Save/apply the changes.
* Verify the Subscription YAML now contains the time window and observe that deployment actions respect the scheduling window.
Why this matters:
* Time windows let you control when changes roll out (useful for change-management, business hours, and maintenance windows).


質問 # 36
Create Production ClusterSet

正解：

解説：
See the solution below in Explanation.
Explanation:
* Create the ManagedClusterSet:
* oc create managedclusterset production
* Validate:
* oc get managedclusterset
* oc describe managedclusterset production
Why this matters:
* Separating development and production clusters is common for governance/RBAC isolation.


質問 # 37
Create Overlay Directory (Kustomize)

正解：

解説：
See the solution below in Explanation.
Explanation:
* Create overlay structure:
* mkdir -p overlays/production
* Confirm:
* ls -R overlays
Why this matters:
* Kustomize overlays let you maintain base manifests and environment-specific patches (production vs dev, etc.).
