Several pods for an integration capability are stuck in Pending state. The events show: "0/6 nodes are available: pod has unbound immediate PersistentVolumeClaims". What is the most likely cause?

An organization wants to standardize how integration instances are deployed and updated across multiple clusters using a Git-based approval workflow. Which approach aligns best with this requirement?

A mission-critical messaging workload requires that IBM MQ queue managers continue to operate during an OpenShift node failure with minimal message loss and without manual intervention. Which design choice best supports this requirement?

After enabling restricted network access, an administrator notices that operator upgrades and some reconciliation actions fail intermittently. Cluster events show timeouts when contacting external registries. What is the most robust solution to stabilize operations in a restricted environment?

An administrator needs to expose the IBM Cloud Pak for Integration Platform UI to users in the corporate network. The OpenShift cluster uses a default Ingress controller and corporate DNS is already configured for the cluster router. What is the recommended approach to provide access?

A security team requires that all integration runtime containers run without root privileges. Which configuration best aligns with OpenShift and Cloud Pak for Integration best practices?

A newly deployed integration instance shows pods stuck in Pending. The administrator suspects insufficient cluster resources. Which OpenShift command provides the most direct view of whether CPU/memory requests cannot be scheduled?

An organization wants to centrally manage multiple Cloud Pak for Integration capabilities (MQ, ACE, Event Streams, API Connect) using GitOps. Which approach is most aligned with OpenShift GitOps best practices?

A team needs to allow developers to deploy App Connect Enterprise (ACE) integration servers but prevent them from modifying cluster-scoped resources. What is the best way to achieve this in OpenShift?

After enabling TLS for an integration endpoint, clients begin failing with certificate validation errors. The endpoint presents a certificate signed by an internal CA. What is the most likely remediation?

An integration runtime pod is repeatedly restarting with an OOMKilled reason. The workload has periodic spikes but must remain available. Which change is the best first step?

A cluster administrator needs to configure persistent storage for multiple Cloud Pak for Integration capabilities, ensuring dynamic provisioning and avoiding manual PV creation. Which storage configuration best supports this requirement?

A team runs IBM MQ in Cloud Pak for Integration and needs to rotate TLS certificates used for channel security with minimal downtime. What is the best practice approach?

An administrator observes that the Cloud Pak for Integration operators are healthy, but a capability instance reconciliation is failing with RBAC-related errors in the operator logs. The instance is deployed in a dedicated namespace. What is the most likely root cause?

An administrator needs to allow developers to create and manage Platform Navigator instances in one namespace, but must prevent them from modifying cluster-wide resources. Which approach is recommended?

A new Cloud Pak for Integration capability is being installed and the operator pod is running, but the custom resource (CR) remains in a pending state and no operand pods are created. What is the most likely next place to check for the root cause?

A team wants to expose an integration endpoint externally with TLS termination and host-based routing in OpenShift. Which standard OpenShift resource is typically used for this purpose?

An administrator must ensure that workloads in a CP4I namespace cannot consume unlimited CPU and memory, while also providing default requests/limits for new pods. Which Kubernetes/OpenShift object best satisfies this requirement?

A company requires that CP4I operators and operands pull images from an internal mirrored registry due to restricted outbound connectivity. Which configuration is most directly used to make the cluster trust and pull from that mirrored registry?

After deploying an integration capability, several operand pods are stuck in ImagePullBackOff. Other pods in the namespace run normally. Which action is most likely to resolve the issue?

A security team mandates that integration workloads must not run as root and must use the most restrictive feasible security settings in OpenShift. Which mechanism is primarily used to enforce this at the pod level?

A CP4I deployment must be designed so that a single namespace hosts multiple integration capabilities, but administrative tasks should be delegated by capability (for example, different teams manage different CRs). What is the best practice to achieve this while maintaining least privilege?

A cluster uses a default StorageClass that provisions storage with ReadWriteOnce access mode. An administrator plans to scale a stateful integration component across multiple nodes and expects concurrent access to shared persistent storage. What is the best architectural guidance?

A production CP4I capability intermittently becomes unresponsive. Metrics show frequent pod restarts due to OOMKilled, but cluster nodes still have free memory. The deployment uses low memory limits and higher memory requests. Which change is most appropriate to improve stability while keeping scheduling predictable?

An administrator wants to verify that IBM Cloud Pak for Integration can pull images from the internal registry during installation. Which Kubernetes resource is typically required to provide registry credentials to the pods?

A platform team wants to delegate day-to-day operations of the Platform UI to an operations group without granting full cluster-admin. What is the best practice approach?

A developer reports they cannot access an integration endpoint exposed by Cloud Pak for Integration. The service is running, but external traffic fails. What is the first OpenShift object an administrator should check for the externally accessible route configuration?

An administrator is planning high availability for IBM MQ in Cloud Pak for Integration. Which approach aligns best with a resilient design on Kubernetes?

After deploying an integration capability, multiple pods remain in Pending state. Node CPU and memory appear sufficient. What is the most likely cause if the events show "0/.. nodes are available: pod has unbound immediate PersistentVolumeClaims"?

A team needs to enforce consistent resource limits for all integration runtime pods across multiple namespaces to avoid noisy-neighbor issues. Which OpenShift/Kubernetes control is most appropriate?

An administrator must design network access so that only a specific set of namespaces can call the API endpoints of a CP4I capability in a "shared services" namespace. What is the most robust approach on OpenShift?

A cluster uses an admission policy that blocks privileged containers. After installing CP4I operators, an integration capability fails to start, and events indicate the pod is denied due to security context constraints. What is the best corrective action that aligns with OpenShift security best practices?
