EX432 Exam Guide

This EX432 exam focuses on practical knowledge and real-world application scenarios related to the subject area. It evaluates your ability to understand core concepts, apply best practices, and make informed decisions in realistic situations rather than relying solely on memorization.

This page provides a structured exam guide, including exam focus areas, skills measured, preparation recommendations, and practice questions with explanations to support effective learning.

 

Exam Overview

The EX432 exam typically emphasizes how concepts are used in professional environments, testing both theoretical understanding and practical problem-solving skills.

 

Skills Measured

  • Understanding of core concepts and terminology
  • Ability to apply knowledge to practical scenarios
  • Analysis and evaluation of solution options
  • Identification of best practices and common use cases

 

Preparation Tips

Successful candidates combine conceptual understanding with hands-on practice. Reviewing measured skills and working through scenario-based questions is strongly recommended.

 

Practice Questions for EX432 Exam

The following practice questions are designed to reinforce key EX432 exam concepts and reflect common scenario-based decision points tested in the certification.

Question#1

SIMULATION
Task 27
Troubleshoot a managed cluster stuck “NotReady” by checking klusterlet/agent components

A. 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).

Question#2

SIMULATION
Task 14
Install RHACS Operator (Web Console)

A. In OpenShift Web Console, go to Operators → OperatorHub.
Search for Advanced Cluster Security.
Select Red Hat Advanced Cluster Security for Kubernetes (RHACS).
Click Install and follow the wizard (namespace/channel per lab).
After operator installation, create RHACS components (as the hint indicates):
Install/Deploy Central (the management plane)
Install/Deploy SecuredCluster (sensor/collector on clusters)
Confirm operator and pods are running:
Operators → Installed Operators
oc get pods -n <rhacs-namespace>
Why this matters:
RHACS adds container security posture management, vulnerability management, and runtime policy enforcement.

Question#3

SIMULATION
Task 44
Configure a maintenance window for deployments (time window concept) and validate drift

A. Edit the subscription/app definition to include a time window (active or blocked window).
Attempt a change outside the window and observe behavior (no rollout until window).
Confirm rollout during window.

Question#4

SIMULATION
Task 9
Create ETCD Encryption Policy (Web Console)

A. Open the ACM console on the hub.
Navigate to Governance → Policies.
Click Create policy.
Set Name: policy-etcd.
Choose the policy template/type ETCD Encryption.
Set Remediation action to enforce.
inform = report only
enforce = attempt to automatically remediate to desired state Select clusters/ClusterSets to apply (depends on the wizard). Click Submit.
Verify compliance once applied:
In console, check policy status: Compliant/NonCompliant
Or via CLI:
oc get policy -A
oc describe policy policy-etcd -n <policy-namespace>
Why this matters:
Governance policies are a core ACM feature for enforcing security baselines across multiple clusters.

Question#5

SIMULATION
Task 10
Deploy GitOps Application (Subscription YAML)

A. Apply the subscription/application manifest:
oc apply -f application-subscription.yaml
Confirm resources were created:
oc get applications.app.k8s.io -A
oc get subscriptions.apps.open-cluster-management.io -A oc describe application.app.k8s.io my-app -n <namespace>
Watch placement/propagation (varies by model used in the lab):
oc get placement -A
oc get placementrule -A
Why this matters:
ACM “application” deployment commonly uses Subscription/Placement (legacy model) or newer Placement resources, enabling multi-cluster rollout from Git sources.
