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

An administrator is preparing to install IBM Cloud Pak for Data on an OpenShift cluster. As a best practice, what should be validated FIRST to avoid most installation failures?

A security team requires that Cloud Pak for Data users authenticate with the company’s enterprise identity provider and that group membership controls access to platform roles. Which approach best meets this requirement?

A data engineer reports that a newly provisioned database service instance is stuck in a "Provisioning" state for an extended period. What is the MOST appropriate first troubleshooting step for an administrator?

An administrator needs to ensure that Cloud Pak for Data workloads can dynamically request persistent storage without manual intervention. Which Kubernetes/OpenShift concept enables this behavior?

A company wants to separate responsibilities: platform administrators manage the Cloud Pak for Data platform, while service administrators manage only specific data services. What is the best practice to achieve this separation?

After integrating a new object storage endpoint for Cloud Pak for Data, users can create connections but receive authorization errors when accessing buckets. The access key and secret are confirmed correct. What is the MOST likely cause?

Multiple Cloud Pak for Data pods are repeatedly restarting with messages indicating they were terminated due to memory pressure. What is the BEST corrective action to prevent recurrence?

A team wants a repeatable way to install and maintain multiple Cloud Pak for Data services while ensuring dependencies are consistently handled by the platform. Which mechanism is primarily responsible for orchestrating service lifecycle on OpenShift?

A Cloud Pak for Data deployment requires strict network segmentation so that only approved namespaces can communicate with a sensitive data service namespace. Which approach best enforces this requirement in OpenShift?

An administrator plans to migrate Cloud Pak for Data to a new cluster. The goal is to minimize data loss for stateful services while keeping the process supportable. What is the BEST high-level approach?

An administrator needs to confirm the Cloud Pak for Data web client is reachable through the cluster’s ingress after installation. Which action is the most direct validation?

A new administrator is asked to grant a user the ability to create and manage projects in Cloud Pak for Data, but not manage the overall platform configuration. Which is the best approach?

An administrator wants to ensure that Cloud Pak for Data workloads continue running during a planned node reboot. Which Kubernetes capability is primarily used to move pods to other nodes?

After enabling an external LDAP identity provider, users can authenticate to OpenShift but cannot log in to Cloud Pak for Data. The Cloud Pak for Data login page shows 'user not found' after successful authentication. What is the most likely cause?

A team is installing a new data service in Cloud Pak for Data. The service operator is installed, but the service instance provisioning stays in a pending state due to insufficient cluster resources. Which action best addresses this while following best practices?

A Cloud Pak for Data upgrade has completed, but one service shows 'Not Ready' while others are healthy. You need to identify whether the issue is with the service operator reconciliation or with the service instance pods. What is the best first step?

Multiple Cloud Pak for Data users report slow UI performance and timeouts when browsing assets. Cluster CPU and memory are normal, but persistent volumes show high latency. Which optimization is most appropriate?

An administrator wants to design network access so that only a limited set of internal subnets can reach the Cloud Pak for Data route, while still allowing platform components to communicate within the cluster. Which approach is most appropriate?

A Cloud Pak for Data service uses internal certificates and begins failing after a certificate rotation event. Pods are running, but API calls between components return TLS handshake errors. What is the best corrective action?

A company must meet strict isolation requirements: certain regulated workloads in Cloud Pak for Data must not share worker nodes with non-regulated workloads. Which design best meets this requirement on OpenShift?

An administrator is preparing an air-gapped installation of IBM Cloud Pak for Data. The cluster nodes cannot access public container registries. Which approach is the BEST practice to ensure the platform can pull all required images during installation and subsequent service enablement?

After a planned worker node maintenance, several Cloud Pak for Data platform pods remain in Pending state. The events show "0/.. nodes are available: node(s) had taint {node.kubernetes.io/unschedulable: }". What should the administrator do to restore normal scheduling?

A security team requires that application users do not receive direct cluster-admin privileges, but administrators must still manage Cloud Pak for Data platform resources using least privilege. Which approach best meets this requirement?

A team is onboarding a new data service in Cloud Pak for Data and must ensure its persistent data survives pod restarts and can be moved between nodes. Which storage characteristic is MOST important to verify for the service's persistent volume claims?

A Cloud Pak for Data deployment intermittently fails user logins. The platform routes are reachable, but authentication requests occasionally time out. Cluster monitoring shows saturation on the ingress controller and uneven pod distribution. What is the BEST corrective action to improve availability and reduce timeouts?
