IBM Cloud Pak for Data v4.x Administrator Practice Exam 2025: Latest Questions

An administrator is preparing an OpenShift cluster for IBM Cloud Pak for Data. Which prerequisite best ensures platform services can persist data reliably across node failures?

After deploying Cloud Pak for Data, users report they can reach the OpenShift console but cannot access the Cloud Pak for Data web UI route. Which is the most likely cause to check first?

A security team requires that Cloud Pak for Data administrators can manage platform services but cannot modify cluster-wide resources outside the CP4D project/namespace. What is the best practice approach?

A CP4D administrator needs to temporarily stop a service to perform maintenance, but wants to minimize impact to other services running on the platform. Which action is most appropriate?

During installation, the CP4D operator reports reconciliation failures due to insufficient permissions. The installer used a service account intended to be limited to the CP4D namespace. What is the recommended fix?

Users complain that CP4D UI is slow intermittently. The administrator wants to quickly determine whether the issue is resource pressure or application errors. Which first step provides the best signal with minimal changes?

After integrating an external LDAP identity provider, some users can log in but do not see expected projects/spaces in Cloud Pak for Data. Authentication succeeds. What is the most likely missing configuration?

A platform upgrade is planned. Which approach best reduces risk and downtime while maintaining the ability to roll back if validation fails?

A CP4D deployment uses an external object storage endpoint for core platform functions. After a certificate rotation on the object storage side, multiple pods begin failing with TLS errors when accessing the endpoint. What is the most appropriate corrective action?

A service deployment repeatedly fails because pods remain in Pending state with events indicating 'node(s) had taint ... that the pod didn't tolerate' and 'insufficient cpu'. The platform team wants a resilient design rather than a one-off fix. What is the best long-term solution?

After installing Cloud Pak for Data, an administrator wants to verify that the platform is ready before deploying any services. Which approach is the most appropriate first validation step?

A user reports they cannot access the Cloud Pak for Data web UI and receives a browser certificate warning. The platform is otherwise healthy. What is the best practice fix?

An administrator wants to ensure that only authorized users can create projects and deploy services on Cloud Pak for Data. Which control best addresses this requirement?

A Cloud Pak for Data deployment shows pods repeatedly restarting. `oc describe pod` indicates the containers are being killed with an out-of-memory condition. What is the best next step to resolve the issue?

A team needs to integrate Cloud Pak for Data authentication with their corporate directory so that user lifecycle (joiner/mover/leaver) is centrally managed. Which integration is most appropriate?

An administrator is planning worker node maintenance and wants Cloud Pak for Data workloads to reschedule safely with minimal disruption. Which OpenShift feature is most relevant to ensure graceful eviction and availability?

A service deployment fails because persistent volumes cannot be provisioned dynamically. The cluster has multiple storage classes, but the installer did not specify one. What is the most likely cause and fix?

Users report intermittent failures when calling the Cloud Pak for Data API endpoints. The routes exist, but some requests time out. Which is the best first place to look to confirm whether the issue is caused by the OpenShift router/ingress layer?

A regulated organization requires that all platform and service logs for Cloud Pak for Data be retained centrally and correlated with cluster events for audit and incident response. Which architecture best meets this requirement?

A company operates multiple OpenShift clusters and wants a repeatable, controlled process to deploy Cloud Pak for Data services with consistent configuration (limits, storage classes, and integration endpoints). Which approach is most aligned with best practices for consistency and governance?

An administrator is asked to validate that Cloud Pak for Data routes external traffic securely through the cluster’s ingress layer and not directly to service pods. Which Kubernetes/OpenShift resource should the administrator inspect first to confirm the externally exposed endpoint configuration?

A platform admin wants to enforce least privilege for day-2 operations by allowing a group to view platform health and basic status, but not install services, change configuration, or manage users. What is the best approach?

A newly deployed service shows pods stuck in Pending state. The events indicate "0/… nodes are available: insufficient cpu". Which action is the most appropriate first step to remediate without changing the service configuration?

After enabling an internal container registry integration for Cloud Pak for Data workloads, image pulls intermittently fail with unauthorized errors from some namespaces. The cluster uses separate service accounts per namespace. What is the most likely root cause?

A Cloud Pak for Data upgrade completed, but some platform operators keep restarting and the overall platform status remains degraded. The admin suspects a dependency operator is unhealthy. Which is the best next diagnostic step to identify the failing operator component and its reason?
