The EX432 exam validates your expertise in managing and deploying Red Hat Advanced Cluster Management for Kubernetes (RHACM) across multi-cluster environments. This certification, part of the Red Hat Openshift Certifications path, is designed for experienced OpenShift administrators and platform engineers who need to demonstrate advanced cluster orchestration and governance capabilities. This page outlines the exam syllabus, question formats, and effective preparation strategies to help you build confidence and readiness. Whether you are new to RHACM or refining your multi-cluster skills, understanding the scope and structure of EX432 is the first step toward success.
Use this topic map to guide your study for RedHat EX432 (Red Hat Certified Specialist in OpenShift Advanced Cluster Management) within the Red Hat Openshift Certifications path.
The EX432 exam measures both conceptual understanding and practical decision-making through a mix of question types that reflect real-world cluster management scenarios.
Questions progress in difficulty and emphasize practical application, requiring you to think beyond memorization and apply knowledge to production-like situations.
Effective preparation for EX432 requires structured study aligned to the exam domains and consistent hands-on practice. Plan 4-6 weeks of focused preparation, dedicating time each week to specific topics and progressively building your lab experience. Connect theory to practice by working through real-world scenarios that mirror the question formats you will encounter.

RHACM deployment and configuration, multi-cluster policy management, and access control typically represent the largest portion of exam questions. Observability and GitOps practices are also heavily tested because they reflect modern operational requirements. Prioritize hands-on practice in these areas to maximize your score.
Access control defines who can manage policies, while policies enforce configuration standards across clusters. In practice, you configure RBAC to limit policy creation and modification to authorized teams, then deploy policies that apply security baselines and compliance rules to all managed clusters. Understanding this relationship is critical for designing secure multi-cluster governance models.
You should have at least 3-6 months of practical OpenShift experience and at least 2-4 weeks working with RHACM in a lab or production setting. Prioritize labs that cover cluster attachment, policy deployment, observability configuration, and GitOps integration. Hands-on experience is essential because many exam questions test troubleshooting and configuration decisions that require familiarity with the RHACM console and CLI.
Candidates often misunderstand the distinction between hub and managed cluster responsibilities, leading to incorrect policy or RBAC configurations. Another frequent error is overlooking observability prerequisites or misconfiguring metrics retention policies. Finally, not testing GitOps workflows end-to-end before the exam often results in missed scenario-based questions. Review each topic twice and test your configurations in a lab before exam day.
Reduce new material intake and focus on reviewing weak areas identified in practice tests. Complete one full-length timed mock exam to assess pacing and confidence. Spend 30 minutes each day reviewing policy templates, RBAC configurations, and common troubleshooting steps. Get adequate sleep and avoid cramming, as fatigue impairs decision-making on scenario-based questions.
SIMULATION
Task 22
Switch a policy from enforce inform (report-only) and validate behavior
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).
SIMULATION
Task 26
Detach (unimport) a managed cluster safely from the hub
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.
SIMULATION
Task 29
Configure Observability (MultiClusterObservability) with object storage credentials
Create the object storage secret (you'll be given endpoint/access keys in an exam):
oc -n open-cluster-management-observability create secret generic thanos-object-storage \
--from-file=thanos.yaml=/path/to/thanos.yaml
Create or edit MultiClusterObservability CR to enable observability (storage class, retention, etc.).
Verify observability pods in the observability namespace and check dashboards/metrics.
Why this matters:
Monitoring health/performance with ACM observability is a common learning objective in ACM training.
SIMULATION
Task 6
Bind Cluster to ClusterSet
Task information: Add cluster-dev to the development ClusterSet.
Confirm the cluster is present on the hub:
oc get managedcluster
Bind cluster-dev to development:
clusteradm clusterset bind --clusterset development --cluster cluster-dev
Verify membership (common checks):
oc get managedclustersetbindings -A
oc get managedclusterset development -o yaml
oc get managedcluster cluster-dev -o yaml | grep -i clusterset -n
Why this matters:
ClusterSet binding is what allows RBAC/users/apps/policies scoped to that ClusterSet to target the cluster.
SIMULATION
Task 32
Create a Placement that selects clusters by OpenShift version label and exclude a region
Ensure clusters have labels like openshiftVersion=4.18 and region=us-west etc.
Create placement with matchExpressions (include one label, exclude another):
matchExpressions:
- key: openshiftVersion
operator: In
values: ['4.18']
- key: region
operator: NotIn
values: ['us-west']
Validate PlacementDecision.
