An organization requires that integration runtime pods can only run on a specific set of worker nodes dedicated to integration workloads. Which configuration best achieves this goal?

A security team mandates that private keys used by an integration component must never be stored in plaintext in Git and should be rotated without redeploying the entire cluster. What is the recommended Kubernetes-native mechanism to manage these keys?

A company wants to expose APIs externally with consistent authentication, rate limiting, and analytics while keeping backend services private. Which CP4I capability should be used as the primary entry point for external consumers?

During an outage investigation, multiple integration pods were evicted and restarted frequently due to node pressure, causing instability. Which preventive configuration is most appropriate to improve availability during planned disruptions and reduce simultaneous restarts?

A CP4I deployment uses persistent storage for stateful components. After moving to a new storage class, new pods fail to mount volumes and events indicate an access mode mismatch (e.g., requested RWX but provided RWO). What is the best resolution?

An administrator needs to allow a new group of users to create and manage Platform Navigator instances, but should not grant cluster-admin on OpenShift. Which approach is recommended?

A team is using the IBM Cloud Pak for Integration UI and wants a single place to monitor deployed integration runtimes (e.g., App Connect, MQ, API Connect) and access their consoles. Which component provides this consolidated experience?

An administrator needs to rotate a TLS certificate used by an integration endpoint exposed through OpenShift routes. What is the most appropriate action?

A new MQ Queue Manager deployed by Cloud Pak for Integration fails to start. The logs show permission errors writing to the persistent volume mount. What is the most likely root cause?

A customer wants to deploy multiple integration capabilities in the same OpenShift cluster. Security requires strict isolation so teams cannot view or modify each other’s integration resources. What design is most appropriate?

An administrator needs to ensure that integration workloads can pull images from a private registry without embedding credentials in pod specs. What is the recommended approach?

A team plans to implement an API-led architecture using Cloud Pak for Integration. They need a component specifically designed to manage APIs, enforce policies, and publish a developer portal. Which capability best fits this requirement?

After installing CP4I operators, an operator’s Subscription remains in 'AtLatestKnown' but the ClusterServiceVersion (CSV) does not reach 'Succeeded'. The CSV shows missing required CRDs. What is the best next step?

A production CP4I environment has multiple integration runtimes. The cluster experiences intermittent latency spikes during peak load. The SRE team wants a method to identify whether the bottleneck is CPU throttling, memory pressure, or storage I/O saturation without modifying application code. What is the best approach?

An enterprise requires that all secrets used by integration runtimes (e.g., keystores, passwords) be centrally managed with audit controls and rotated regularly. They want to avoid storing sensitive values directly in GitOps repositories. Which design best meets this requirement on OpenShift?

An administrator needs to confirm that the IBM Cloud Pak for Integration operators are healthy after a cluster maintenance window. Which Kubernetes resource is the MOST direct indicator that each installed operator is running and has an available controller?

A team wants developers to self-provision capabilities (e.g., App Connect, MQ) but only within a specific namespace and without cluster-wide permissions. Which approach BEST meets this requirement?

An administrator is asked to expose a Cloud Pak for Integration capability route securely and ensure TLS is terminated at the OpenShift router. Which method is MOST appropriate?

A company wants to run IBM MQ in a highly available configuration in Cloud Pak for Integration. Which MQ deployment pattern is designed for native Kubernetes high availability with automated failover?

After deploying an integration capability, pods remain in Pending state due to insufficient resources. What is the BEST next step to validate the scheduling failure reason?

A platform team needs to ensure that CP4I operands are separated from platform operators for operational control and lifecycle management. Which design BEST aligns with this goal?

An administrator wants to reduce risk when applying configuration changes to an App Connect runtime in production. Which approach is MOST appropriate to support controlled rollout and quick rollback?

A team is designing event-driven integration and wants to decouple producers and consumers while supporting replay and multiple independent consumer groups. Which capability component BEST fits this requirement?

A company requires end-to-end encryption for traffic between CP4I components inside the cluster, not just at the edge router. Which design choice BEST supports this requirement with minimal application changes?

An administrator wants to grant a developer permission to view the IBM Cloud Pak for Integration (CP4I) Platform UI and inspect instance status, but not create, modify, or delete any integration instances. Which approach best follows least-privilege practices?

A CP4I deployment uses multiple integration capabilities. The security team requires all external access to be encrypted in transit and routed through a single entry point with consistent TLS configuration. Which OpenShift/CP4I approach best meets this requirement?

A new administrator is asked to verify whether the CP4I Platform Navigator is healthy after a maintenance window. Which check provides the most direct indication of Platform Navigator availability to users?

A team wants to run Event Streams in CP4I and ensure storage remains consistent during node failures. Which storage characteristic is most important for the persistent volumes backing Kafka brokers?

After enabling stricter network controls, an App Connect Enterprise (ACE) integration server cannot call an internal REST service hosted in another namespace. Pods are running, but requests time out. What is the most likely cause and best next step?
