Online Access Free EX432 Practice Test

See the solution below in Explanation.
Explanation:
* Check cluster conditions:
oc describe managedcluster cluster-dev
* Check agent namespaces and pods on the managed cluster (common namespace names depend on deployment, but you're looking for ACM/klusterlet agents).
* On hub, check managedclusteraddons and addon health:
oc get managedclusteraddon -n cluster-dev
oc describe managedclusteraddon -n cluster-dev < addon-name >
* Typical fixes: missing pull secret, network/DNS issues, CSR approval issues, etc. (Exam expects you to identify from events/conditions).

See the solution below in Explanation.
Explanation:
* Log in to the OpenShift Web Console as a cluster-admin user.
* Go to Operators # OperatorHub .
* OperatorHub is the catalog of available operators.
* In the search box, type: Advanced Cluster Management .
* Click Advanced Cluster Management for Kubernetes (Red Hat ACM).
* Click Install .
* In the install wizard:
* Update channel : choose the recommended/stable channel for your lab.
* Installation mode : typically "All namespaces on the cluster" (default).
* Installed Namespace : select or create open-cluster-management .
* Click Install and wait for the operator to show Succeeded in:
* Operators # Installed Operators .
Why these steps matter:
* Installing the ACM operator creates the CRDs/controllers required to run the Hub components (MultiClusterHub) that manage/import other clusters.

See the solution below in Explanation.
Explanation:
* Open the RHACS (Central) console (typically via a route created by Central).
* Navigate to: Platform Configuration # System Policies .
* Click Create Policy .
* Set the policy criteria:
* Add a rule/condition such as Image OS = debian:10 (as required by the lab)
* Set enforcement to apply at Build & Deploy stages.
* Build prevents images from being admitted into pipeline/registries depending on integration.
* Deploy prevents or flags deployments that violate policy.
* Save the policy.
* (Optional validation) Trigger a test deployment/image that matches debian:10 to confirm alerts
/enforcement behavior.
Why this matters:
* Enforcing at build+deploy catches risky images earlier and prevents policy violations from reaching runtime.

See the solution below in Explanation.
Explanation:
* On hub: inspect managed cluster conditions for certificate issues.
* Check pending CSRs (if applicable in your lab):
oc get csr
* Approve relevant CSRs and verify managed cluster returns Ready. Why this matters: Certificate- driven trust is core to "secure clusters" operations in ACM.

See the solution below in Explanation.
Explanation:
* Write a Policy # ConfigurationPolicy enforcing a ConfigMap (name, namespace, data keys).
* Bind to placement.
* Verify on a managed cluster:
oc get configmap -n < ns >
oc describe configmap -n < ns > < name >
