After creating an App Connect runtime instance, the pods start but no HTTP traffic reaches the service. Other cluster services are accessible. Which OpenShift resource is most commonly required to expose the runtime externally using standard OpenShift ingress?

A company runs multiple integration capabilities in one cluster. They want consistent, centralized authentication for the Platform Navigator UI using their corporate identity provider. Which configuration is most appropriate?

An administrator notices frequent pod restarts for an integration runtime due to memory pressure. The team wants to reduce the chance of OOMKills while keeping resource usage predictable. Which change is most effective?

A team must ensure message data in IBM MQ used by integration flows is encrypted at rest. They can use OpenShift-provided storage encryption and want MQ to use it without changing application code. What is the recommended approach?

After applying a GitOps change, an operator-managed integration instance repeatedly reverts manual edits made directly to its Deployment. What is the best explanation for this behavior?

A customer requires strict network segmentation: only App Connect runtimes should communicate with IBM MQ, and no other pods in the namespace should be able to connect to MQ. What is the most appropriate Kubernetes/OpenShift control to implement this requirement?

An integration environment uses Kafka for event streaming. The cluster is healthy, but producers experience intermittent 'not enough replicas' errors during peak load. Which action best addresses this while maintaining availability goals?

A company wants to standardize deployments so that integration instances are reproducible across dev, test, and prod clusters with minimal drift. They also want approvals for changes and the ability to roll back easily. Which approach best fits these requirements for Cloud Pak for Integration resources?

An administrator needs to grant a developer permission to create and manage only IBM MQ queue managers in a specific namespace, without access to other Cloud Pak for Integration instances in that namespace. Which approach is the BEST fit?

You are asked to validate whether the IBM Cloud Pak for Integration operators are installed correctly and ready before creating any instances. What is the MOST direct way to confirm readiness using OpenShift?

A team wants single sign-on across the Platform Navigator and integration component UIs. Which integration provides the most consistent SSO experience when configured correctly?

An administrator needs to expose an integration component’s UI securely to external users. What is the recommended OpenShift-native method?

After enabling a stricter Pod Security policy in the cluster, an App Connect Dashboard instance fails to start and its pods show permission-related errors when mounting volumes. What is the BEST next step to resolve this while maintaining security controls?

A developer reports that the Platform Navigator shows an integration instance as 'Ready', but clicking its tile fails with a 503 error. Which is the MOST likely OpenShift cause to investigate first?

A company needs to separate duties between two teams: one team manages the CP4I platform (operators, Navigator), and another manages only integration runtimes (creating/updating instances). Which design best supports this separation?

An organization requires that integration runtime pods are spread across nodes to reduce the impact of a single node failure. Which Kubernetes/OpenShift feature should be used to enforce this scheduling behavior?

An IBM MQ queue manager deployed on OpenShift experiences intermittent application timeouts. Metrics show CPU throttling, but memory is stable. The queue manager’s pod has CPU limits equal to requests. What is the BEST optimization approach?

A namespace hosting multiple integration components is approaching its resource quota limits, and new pods remain in 'Pending' due to insufficient CPU. The business requires maintaining high availability for production workloads while allowing non-production to degrade first. What is the BEST cluster-native strategy?
