An administrator is planning to grant a CI/CD pipeline permission to deploy capability instances (create CRs) in a single namespace. Which credential method is most appropriate?

Multiple integration workloads are running in the same OpenShift cluster. The platform team wants to prevent one workload from consuming excessive CPU and memory and impacting others. Which Kubernetes/OpenShift feature should be applied at the namespace level?

A capability instance remains in a "Pending" or "NotReady" state. Pod events show repeated scheduling failures due to "persistentvolumeclaim not found". What is the most likely cause?

Security policy requires that secrets such as keystore passwords and API credentials are not stored in plaintext in configuration maps or embedded in Custom Resources. What is the recommended approach in OpenShift for providing these values to Cloud Pak for Integration workloads?

After an OpenShift node maintenance window, an IBM Cloud Pak for Integration operand fails to start. The pod is stuck in CrashLoopBackOff. Logs show the container cannot write to a mounted volume due to permission denied. What is the most likely remediation?

A regulated enterprise needs auditable separation of duties: platform administrators manage Operators and cluster configuration, while integration teams manage only their own capability instances. The solution must support multiple teams on one cluster. Which architecture and governance approach best meets this requirement?

An administrator needs to verify that the IBM Cloud Pak for Integration (CP4I) operators are healthy after installation. Which check is the most direct indicator that the operators are installed and reconciling normally?

A security team requires that workloads in the CP4I namespace do not run with root privileges and must comply with OpenShift Security Context Constraints (SCC). What is the best practice to meet this requirement for CP4I components?

A platform engineer wants to confirm that CP4I route-based endpoints are reachable from outside the cluster. Which OpenShift object is most commonly used to expose CP4I web UIs and APIs externally when using the OpenShift router?

A team needs to separate duties so that application developers can create Integration Server instances but cannot change cluster-wide operator subscriptions or install new operators. Which approach best implements this separation in OpenShift?

After deploying a CP4I capability, some pods remain Pending. The events show: "0/6 nodes are available: 6 Insufficient cpu." What is the best immediate administrative action?

An organization must ensure that all CP4I traffic between components is encrypted in transit and that certificates are centrally managed. Which design is most aligned with this requirement?

A CP4I instance upgrade is planned. The administrator wants to minimize risk by ensuring the operator is tested with the current environment before applying changes broadly. What is the recommended approach?

A CP4I platform uses an external database for a capability. During failover testing, the capability becomes unavailable even though Kubernetes pods are running. Logs indicate repeated connection failures to the database endpoint. What is the most robust architectural improvement?

A compliance audit requires proof that only approved container images are running for CP4I workloads and that images are scanned before use. Which control best satisfies this requirement on OpenShift?

An administrator notices that CP4I operator reconciliation repeatedly reverts manual changes made to a managed Deployment (e.g., changing environment variables directly in the Deployment). What is the correct way to make persistent configuration changes?

An administrator needs to confirm that the IBM Cloud Pak for Integration platform UI is reachable after installation on OpenShift. Which OpenShift resource is most directly used to expose the platform UI externally?

A team wants developers to self-service create integration instances but must restrict them to a specific namespace and prevent changes to cluster-wide resources. Which approach best meets this requirement?

An integration instance is stuck in a 'Pending' state and the pods show 'Insufficient cpu' scheduling events. What is the most appropriate immediate action to restore scheduling?

A platform administrator wants to prevent a runaway integration flow from consuming excessive resources on a shared OpenShift cluster. Which Kubernetes mechanism is best aligned with this goal?

A company must ensure all outbound connections from integration runtimes to external systems use a corporate proxy. Where should this be configured to consistently affect operator-managed workloads?

An administrator wants to rotate TLS certificates used by an integration endpoint without redeploying the entire integration instance. What is the recommended approach in OpenShift/Kubernetes?

After a cluster upgrade, an integration capability's operator shows as running, but newly created instances never progress beyond 'Reconciling'. Operator logs show repeated authorization errors when reading resources in its namespace. What is the most likely cause?

A team reports intermittent failures when calling an integration API. The failures correlate with pod restarts, and events show liveness probe failures. What is the best next step to stabilize the workload while preserving health checking best practices?

An enterprise requires strict tenant isolation: multiple teams will deploy integration runtimes, but they must not be able to view or access each other’s Secrets, ConfigMaps, or instance custom resources. The cluster is shared. Which architecture best meets this requirement?

A production deployment uses operator-managed integration instances with persistent storage. The administrator must design a backup strategy that supports recovery to a new cluster after a disaster. Which approach is most appropriate?
