IBM Cloud Pak for Integration v2021.1 Administration Advanced Practice Exam: Hard Questions 2025

An enterprise is installing IBM Cloud Pak for Integration on OpenShift in a restricted (air-gapped) network. During the Platform UI installation, the operator subscriptions succeed, but the Custom Resources remain in a pending state and pods repeatedly show image pull failures. The cluster uses an internal registry mirror and ImageContentSourcePolicy is already applied. Which action most directly resolves the root cause in a way aligned with Cloud Pak best practices for disconnected installs?

A team is designing a highly available Cloud Pak for Integration deployment across multiple OpenShift worker nodes. They must minimize blast radius and satisfy a requirement that a single node failure cannot take down all integration runtime pods for a given capability (e.g., MQ or ACE). Which combination of Kubernetes/OpenShift constructs best meets this requirement with minimal ongoing administration?

After installing Cloud Pak for Integration, the Platform UI is accessible, but creating a new instance of an integration capability fails immediately with RBAC errors indicating insufficient permissions to create resources in the target namespace. The cluster uses GitOps and the security team forbids granting cluster-admin to the Platform UI service account. What is the most appropriate fix that maintains least privilege while enabling self-service provisioning via the Platform UI?

An organization runs multiple CP4I capabilities in a shared OpenShift cluster with strict tenancy. A new requirement mandates that integration developers can view logs and status for their own IntegrationServer and EventStreams instances but must not be able to list secrets, modify NetworkPolicies, or view other teams’ namespaces. Which approach best satisfies the requirement with the cleanest operational model?

A CP4I environment has intermittent failures when creating new instances through the Platform UI. Operators appear healthy, but some OperandRequests remain stuck in a progressing state. oc describe shows repeated reconciliation attempts with messages indicating missing OperandBindInfo and dependency resolution loops. What is the most likely underlying issue and best next step to confirm it?

A company must enforce that all CP4I workloads communicate only over encrypted channels inside the cluster. They also need to ensure that internal service-to-service traffic cannot bypass mTLS controls. Which approach best addresses this requirement while remaining manageable across multiple integration capabilities?

Security requires that CP4I operators and operands run with the least privilege, and any request for privileged containers or hostPath mounts must be justified and minimized. During a compliance review, a capability deployment is flagged because its pods request elevated SCC permissions. What is the best remediation strategy that preserves supportability?

After a cluster-wide certificate authority change, multiple CP4I capabilities begin failing outbound TLS connections to internal enterprise endpoints. The endpoints use certificates signed by the new internal CA. Pods show errors indicating the certificate chain is not trusted. What is the most robust fix that scales across capabilities and survives pod restarts/redeployments?

A production CP4I cluster experiences periodic latency spikes and message processing delays. Node and pod CPU are not saturated, but p99 latency correlates with storage I/O wait. Several capabilities use persistent volumes heavily. What is the best next diagnostic step to isolate whether the issue is storage-class related versus workload-level tuning?

An operator-managed CP4I operand repeatedly enters CrashLoopBackOff after a routine configuration change. Logs show the application cannot bind to its configured port because it is already in use, but only on certain nodes. The deployment uses hostNetwork=false. Which is the most probable cause and the most appropriate corrective action?
