IBM Cloud Pak for Integration v2021.2 Administration Advanced Practice Exam: Hard Questions 2025

An administrator is installing IBM Cloud Pak for Integration (CP4I) on an OpenShift cluster where worker nodes span multiple subnets. During foundational services installation, pods remain in Pending with events indicating failure to attach to the Multus secondary network and intermittent image pull timeouts. The cluster uses a corporate proxy and an internal registry mirror. Which approach most directly addresses the root cause while aligning with CP4I best practices for air-gapped/proxied installs?

A team uses GitOps to manage CP4I custom resources. After applying a new Platform UI and one capability (MQ) instance in a single sync wave, the UI comes up but does not show the capability, and the MQ instance reports reconciliation errors related to missing licensing and cluster-scoped prerequisites. What is the most robust GitOps strategy to prevent this class of dependency ordering failures?

An organization must isolate multiple tenants on the same OpenShift cluster running CP4I. Each tenant needs platform UI access, separate namespaces, and strict separation of secrets and network traffic. They also require central operations to manage operator upgrades. Which design best meets these requirements with least privilege while maintaining operability?

A CP4I administrator is planning an operator upgrade. The cluster runs multiple capabilities. A previous upgrade caused downtime because some operands restarted simultaneously and exceeded node capacity, triggering eviction and prolonged reconciliation. Which upgrade plan most effectively reduces risk of widespread operand disruption?

A security team requires that all CP4I workloads use short-lived credentials and that no long-lived registry pull secrets are stored in tenant namespaces. The platform currently uses image pull secrets replicated across namespaces. What is the best approach to meet the requirement while keeping deployments functional?

A CP4I administrator needs to implement consistent backup and restore for multiple capabilities that include stateful components. The organization wants application-consistent backups (not just volume snapshots) and the ability to restore to a new namespace in the same cluster for testing. Which strategy best satisfies these requirements?

A solution architect must choose between using IBM MQ, IBM App Connect, and IBM API Connect as the primary integration component for a new program. Requirements: expose managed APIs to internal and external consumers with developer onboarding, enforce consistent policies (rate limiting, OAuth), and provide analytics. Back-end systems include event-driven workloads that will still use messaging. Which is the best primary component choice and why?

A team is designing event-driven integration across microservices on CP4I. They need high-throughput event streaming with replay capability for new consumers, while also requiring exactly-once processing semantics at the consumer application level. Which CP4I capability pattern best fits, and what key design consideration is required to achieve the semantics?

After enabling mTLS on an API gateway endpoint managed within CP4I, clients intermittently fail TLS handshakes. The gateway pods show no restarts, but OpenShift routes are configured with re-encrypt termination. Network team confirms a new intermediate CA was added. Which troubleshooting step is most likely to identify and resolve the issue with minimal disruption?

A CP4I environment experiences periodic latency spikes and timeouts across multiple capabilities. Cluster monitoring shows CPU is stable, but etcd disk I/O latency increases during spikes, and many operators report longer reconcile times. The platform has a high churn rate of custom resources and frequent status updates. What is the best remediation strategy to reduce impact while preserving operational visibility?
