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

An administrator is preparing an OpenShift cluster for IBM Cloud Pak for Integration. Which prerequisite is REQUIRED so the platform operators can be installed and managed correctly?

A platform admin wants to grant a developer permission to create instances (custom resources) of API management and messaging in a specific namespace, without granting cluster-wide administration. What is the BEST approach?

A team needs to expose an HTTP endpoint that can validate JWTs, apply rate limits, and route requests to backend services across namespaces. Which Cloud Pak for Integration capability best fits this requirement?

After deploying an integration runtime, an admin wants to quickly confirm the operator reconciled the custom resource successfully. Where is the MOST direct place to check reconciliation status and recent messages?

A company must install Cloud Pak for Integration in an environment with restricted internet access. They want operator installs to work reliably. What is the BEST approach?

An administrator needs to provide TLS certificates for multiple integration endpoints and rotate them without redeploying application images. Which Kubernetes/OpenShift mechanism is the BEST fit?

A solution must decouple producers and consumers, allow multiple applications to subscribe to the same business events, and support replay of events for new consumers. Which integration capability should be chosen?

A messaging instance fails to become ready. The pods show errors indicating they cannot mount persistent volumes due to 'permission denied' on the filesystem. What is the MOST likely cause in an OpenShift environment?

A customer wants to run multiple Cloud Pak for Integration capabilities across several namespaces. They require centralized governance so only approved teams can create runtime instances, while still allowing self-service in approved namespaces. Which design best meets this requirement?

An operator-managed integration runtime is stuck in a reconcile loop after a configuration change. Logs show repeated failures to connect to a dependent service using an endpoint URL stored in a Secret. The Secret was updated, but the runtime continues using the old value. What is the BEST next step to ensure the operator and workload pick up the change?

An administrator needs to make the IBM Cloud Pak for Integration Platform UI accessible to users through a corporate DNS name and TLS. Which Kubernetes/OpenShift resource is typically used to expose the UI externally in a standard OpenShift deployment?

A team wants to centralize secrets such as passwords and certificates used by integration runtimes running on OpenShift. Which Kubernetes object is intended to store this sensitive data for consumption by pods?

A company wants only users in a specific group to be able to create instances of capabilities (for example, to create a new runtime instance) in a given namespace. Which OpenShift mechanism should the administrator use to enforce this?

An organization wants to separate duties so that one team can manage the platform operators while another team can only manage runtime instances in application namespaces. What is the recommended approach?

A new ACE (App Connect Enterprise) integration server fails to start after deployment. The pod events show an error indicating it cannot pull the container image due to authentication. What is the most likely fix?

A team is designing an event-driven integration where multiple consumer applications must receive the same event message independently. Which messaging pattern/capability best fits this requirement?

An administrator needs to verify why an IntegrationServer custom resource is not being reconciled (no pods are created) even though the YAML was applied successfully. Which is the best first place to look to identify reconciliation errors?

A company wants to enforce that all integration runtime pods run with non-root permissions and disallow privilege escalation. Which OpenShift/Kubernetes feature is most appropriate to enforce these security requirements at the cluster/namespace level?

You are designing a highly available messaging layer using IBM MQ on OpenShift for critical integrations. The requirement is to minimize downtime and ensure message data survives pod/node failures. Which design choice best supports this?

After enabling TLS between clients and an integration endpoint, several clients fail with certificate validation errors. The server certificate was recently replaced. What is the most likely root cause?

An administrator needs to allow developers to access the Cloud Pak for Integration Platform Navigator but must enforce enterprise single sign-on and central group management. Which approach is recommended?

A team wants to reduce resource contention between Integration capabilities by isolating them while still using the same OpenShift cluster. What is the best practice approach?

An administrator needs to grant a developer read-only visibility into the status of deployed integration instances (without allowing changes). What is the most appropriate access method?

A company wants a single entry point for multiple API backends with policies for rate limiting and security enforcement. Which capability best fits this requirement?

After creating an integration instance, pods remain in a Pending state. The events show failed scheduling due to insufficient CPU in the namespace. What should the administrator do first?

A team needs to securely store and rotate credentials used by integration runtimes (for example, database passwords) and avoid embedding secrets in configuration files. Which Kubernetes-native mechanism should be used?

A message-driven integration requires decoupling producers and consumers and ensuring delivery even if consumers are temporarily offline. Which capability is most appropriate?

A cluster uses restricted Security Context Constraints (SCC). An administrator deploys an integration runtime that fails because it attempts to run as root. What is the best corrective action?

An organization requires that only signed and approved container images are allowed to run for integration capabilities. Which control most directly supports this requirement on OpenShift?

An administrator is troubleshooting intermittent failures when calling an API exposed through an API gateway. Backend services are healthy, but clients see sporadic 504/timeout responses. What is the most effective next step to isolate whether the gateway or backend is causing the issue?

An administrator needs to grant a developer permission to create and manage integration instances (e.g., App Connect, MQ, API Connect) but must prevent cluster-wide administrative actions on other namespaces. Which approach is recommended?

A team wants to centrally manage container images used by Cloud Pak for Integration across multiple disconnected OpenShift clusters. Which best practice supports this requirement?

After deploying an integration instance, some pods remain in Pending state. The events show "0/.. nodes are available: pod has unbound immediate PersistentVolumeClaims". What is the most likely cause?

A solution requires exposing REST APIs to internal consumers with policies like rate limiting and JWT validation. Which Cloud Pak for Integration capability is primarily responsible for these functions?

An administrator must apply a corporate certificate authority (CA) so that integration runtimes trust internal TLS endpoints (e.g., internal HTTPS services). What is the recommended approach on OpenShift for broad pod trust of the internal CA?

A platform team needs to ensure only approved teams can create specific Cloud Pak for Integration custom resources (CRs) in their namespaces. Which control is most appropriate?

A developer reports that an integration flow cannot connect to an internal HTTPS endpoint. Pod logs show "x509: certificate signed by unknown authority". What should the administrator do first?

A project wants to implement event-driven integration where multiple consumers independently read the same event stream and maintain their own offsets. Which capability and pattern best fit this requirement?

An administrator is designing an OpenShift cluster for Cloud Pak for Integration and wants to minimize the blast radius of faults while keeping operations manageable. Which architecture choice best supports this goal?

A new deployment must meet strict security requirements: no containers may run as root, and only minimal Linux capabilities are allowed. Some integration pods fail admission with security policy violations. What is the most appropriate administrative action?

An administrator wants to allow developers to view the Platform Navigator and the status of installed capabilities but prevent them from creating or modifying any Cloud Pak for Integration resources. Which approach best meets this requirement?

A team is deploying an integration capability in a restricted (air-gapped) environment. They can access an internal container registry but not the public internet. What is the recommended prerequisite to ensure the installation can pull required images?

An operator reports that messages are successfully produced to IBM MQ but are not appearing in the application consuming them through App Connect. Which initial check is most appropriate from a Cloud Pak for Integration administration perspective?

A company wants to separate duties so that one team manages cluster-level components (operators, storage classes) while another team manages integration instances (ACE dashboards, MQ queue managers, event endpoints) within specific namespaces. What design best supports this separation of duties?

A Platform Navigator is deployed and reachable, but the capability tiles show as unavailable even though the operators appear installed. What is the most likely administrative cause?

An integration team needs to expose an API implemented in App Connect (running on OpenShift) to external consumers with consistent authentication, rate limiting, and analytics. Which capability is the best fit to front the API and provide these policies?

A customer wants to integrate event-driven services and ensure message ordering per key while allowing horizontal scalability of consumers. Which integration capability and pattern best meets this requirement?

An administrator observes frequent restarts of an integration runtime pod. The pod status shows 'OOMKilled'. What is the most appropriate remediation?

A security team requires that all integration capabilities use TLS with certificates issued by the organization’s internal CA. What is the best practice approach to meet this requirement across multiple capabilities on OpenShift?

After enabling network policies in a namespace, an MQ queue manager and an App Connect integration server in the same namespace can no longer communicate. Other apps in the namespace are unaffected. What is the most likely cause and correct fix?
