50 IBM Cloud Pak for Integration v2021.2 Administration Practice Questions: Question Bank 2025

An administrator needs to provide developers a single console to create and manage integration instances (such as App Connect, MQ, and API Connect) on an OpenShift cluster. Which component provides this capability in IBM Cloud Pak for Integration?

A team must ensure that only users in the 'integration-admins' group can create new integration instances in a specific namespace, while developers can view resources but not create them. What is the recommended approach on OpenShift?

An operator-managed integration instance is stuck in a pending state because its persistent volumes are not provisioning. Which is the most likely underlying cause?

You need to quickly check whether an integration operator is healthy and actively reconciling its custom resources. Where is the best place to start?

A company wants integration workloads to be isolated by team while still using a shared OpenShift cluster. They also want to avoid accidental cross-team access to secrets and configmaps. What is the best practice design?

After upgrading an integration operator, existing custom resources stop reconciling and the operator logs indicate a webhook TLS/certificate error. What is the most appropriate remediation step?

An organization needs centralized runtime visibility for IBM MQ queue managers deployed across multiple namespaces, including queue and channel status, without granting broad OpenShift permissions. Which capability is designed for this use case?

A developer reports intermittent 503 errors when calling an API exposed through the platform. The API backend pods show restarts and readiness probe failures. What is the most likely reason clients receive 503 responses?

You are designing a secure deployment where multiple integration capabilities must trust an internal corporate CA for outbound TLS (to call internal services). What is the best practice to implement this consistently across operator-managed workloads?

A production CP4I environment requires that integration instances continue running during planned worker node maintenance. Which design choice best supports this requirement?

An administrator needs to make the IBM Cloud Pak for Integration (CP4I) Platform UI reachable from outside the cluster. Which Kubernetes/OpenShift resource is typically used to expose the Platform UI endpoint to external users?

A team wants different groups of users to administer API management and messaging separately within the same CP4I cluster. Which approach is the recommended way to enforce least privilege?

Following a network segmentation change, App Connect flows intermittently fail when calling a backend service. DNS lookups succeed, but connections time out. Other workloads in the same namespace are unaffected. What is the most likely root cause to investigate first in CP4I/OpenShift environments?

An administrator needs to grant a developer access to create and manage instances of App Connect and MQ within a specific namespace, but must not allow the developer to install operators or change cluster-wide settings. What is the best approach?

You deployed the IBM Cloud Pak for Integration Platform Navigator and it is running, but users cannot access it externally. Internal service connectivity works. Which OpenShift resource is most directly responsible for exposing the application externally?

An operator-managed integration instance is stuck in a reconciling state. You want to quickly determine whether the operator is failing due to missing prerequisites, invalid spec fields, or admission issues. What should you check first?

A team needs to migrate an integration capability configuration between namespaces while keeping credentials secure. They want an approach aligned with Kubernetes best practices. What should they do?

An integration instance fails to start and its pod shows ImagePullBackOff. The cluster uses a private registry that requires authentication. What is the most likely fix?

A company is standardizing observability and wants to correlate logs from CP4I components across namespaces with Kubernetes metadata (namespace, pod, container) for faster troubleshooting. What is the recommended pattern?

A solution architect wants to decouple producers from consumers and allow multiple applications to subscribe to the same business events with independent scaling and delivery. Which CP4I capability best fits this requirement?

During installation, CP4I operators were installed cluster-wide, but the security team mandates that only a specific set of namespaces can host CP4I instances. Which approach best enforces this requirement?

A production MQ deployment in CP4I shows intermittent latency spikes. Metrics indicate CPU throttling, but node CPU is not saturated. The pod has CPU limits set. What is the most likely cause and best corrective action?

An enterprise requires end-to-end encryption for traffic between CP4I components inside the cluster, and they want certificates rotated centrally without manually editing every deployment. Which architectural approach is most appropriate?

An administrator needs to confirm that all IBM Cloud Pak for Integration platform services are installed using a single command. Which approach is most appropriate?

A team deployed an integration instance but cannot access the Platform UI route from outside the cluster. Internal pod-to-service connectivity works. Which is the most likely area to check first?

An administrator wants to allow a group of developers to create and manage integration instances in a single namespace without granting cluster-wide privileges. What is the recommended approach?

A platform operator needs to verify whether a failing pod restart is due to liveness probe failures. Which OpenShift command is most useful?

A customer requires end-to-end encryption for traffic from external clients to integration endpoints while keeping re-encryption at the router. Which route termination mode best meets this requirement?

After enabling OAuth integration, users can log in to the Platform UI but cannot see any instances they previously managed. The instances still exist and are running. What is the most likely cause?

An administrator needs to rotate a TLS certificate used by an integration endpoint with minimal downtime. Which approach is most appropriate?

A CP4I capability shows status 'Degraded' in the UI. The operator pod is running, but reconciliations are failing intermittently. Which troubleshooting step is most appropriate to identify the root cause?

A company wants to expose asynchronous, event-driven integration APIs and decouple producers from consumers using a pub/sub model within Cloud Pak for Integration. Which capability best fits this requirement?

An organization must satisfy strict separation-of-duties: platform operators manage cluster and CP4I operators, while application teams manage only their integration instances. They also need to prevent one team from impacting another team’s workloads. Which design best meets this requirement?

An administrator needs to verify whether the IBM Cloud Pak for Integration platform is correctly using a pre-created OpenShift image pull secret for accessing a private container registry. Which resource is the MOST appropriate place to check this association?

A platform administrator must grant a team read-only access to view all Cloud Pak for Integration instances in a namespace, but the team must not be able to modify any custom resources. What is the BEST approach on OpenShift?

A user reports they cannot log in to the Platform Navigator UI, but the Platform Navigator pod is Running. Which action should the administrator perform FIRST to troubleshoot authentication-related issues?

A company wants to enforce that all integration runtimes deployed by Cloud Pak for Integration use only approved container images from an internal registry. Which OpenShift control provides the MOST effective enforcement at the cluster level?

An operator upgrade was applied and one operand (for example, an integration runtime) is stuck in a Pending or NotReady state. The administrator suspects the operand cannot reconcile due to missing permissions. Where should they look FIRST for evidence of RBAC-related reconciliation failures?

A team needs to expose an integration endpoint externally but must ensure the URL remains stable even if pods are rescheduled. Which is the recommended OpenShift-native method commonly used with Cloud Pak for Integration capabilities to provide a stable external endpoint?

An administrator is planning a namespace layout for multiple application teams using Cloud Pak for Integration. They want to minimize blast radius while still allowing shared platform services. Which design is MOST aligned with best practices?

A flow deployed on an integration runtime is intermittently failing with timeouts when calling an internal service. Cluster monitoring shows occasional CPU saturation on the runtime pods. What is the BEST initial corrective action from a platform administration perspective?

A security team requires that all sensitive configuration for integration runtimes (such as passwords and API keys) be stored encrypted at rest and not embedded in custom resources. Which OpenShift/Kubernetes mechanism is the BEST fit for this requirement in Cloud Pak for Integration deployments?

During an outage, an administrator suspects a misbehaving operator is continuously reconciling and creating excessive API load, impacting the cluster. They need an immediate, reversible action to stop reconciliation for that operand without uninstalling the entire platform. What is the BEST action?
