A service installation on Cloud Pak for Data fails with errors indicating insufficient permissions to create resources such as Roles/RoleBindings in the target namespaces. What is the most appropriate remediation?

A security team mandates strict egress controls: Cloud Pak for Data services may only access a small list of external domains. The cluster already uses standard Kubernetes NetworkPolicies for namespace isolation. Which design is most appropriate to meet the requirement while maintaining supportability?

An administrator must restore Cloud Pak for Data after a disaster. The OpenShift cluster has been rebuilt, but persistent volumes for Cloud Pak for Data were backed up and restored. Users report that some services start but others fail due to missing internal configuration and credentials. Which recovery practice is most likely missing?

An administrator needs to verify that IBM Cloud Pak for Data pods can resolve internal Kubernetes service names (for example, the CPD route and internal services). Which component is primarily responsible for in-cluster DNS name resolution?

A cluster administrator wants Cloud Pak for Data users to authenticate with corporate LDAP and map LDAP groups to platform roles. Where is this integration configured in an OpenShift-based Cloud Pak for Data deployment?

An administrator needs to confirm whether a failing Cloud Pak for Data service pod is being restarted due to repeated health-check failures. Which Kubernetes/OpenShift field or view most directly indicates this?

A Cloud Pak for Data deployment uses an internal image registry mirror. During an upgrade, several pods are stuck in ImagePullBackOff. The admin verifies credentials are correct. What is the most likely next check to resolve the issue?

A platform admin must delegate day-to-day management of Cloud Pak for Data (user onboarding, role assignments, and project-space administration) to a data governance team without granting full cluster-admin privileges. What is the best-practice approach?

Users report intermittent 503 errors when accessing the Cloud Pak for Data web UI. The route exists and DNS is correct. Which investigation is most appropriate first to pinpoint the cause?

A team needs to allow a Cloud Pak for Data service to read data from an S3-compatible object store. What is the recommended way to provide credentials to the service runtime to avoid embedding secrets in images or notebooks?

After enabling a restrictive NetworkPolicy in the Cloud Pak for Data namespace, several services fail to start and show connection timeouts to internal dependencies. Which action is most likely required to restore functionality while keeping a least-privilege network posture?

A Cloud Pak for Data instance experiences random pod evictions during peak hours. Node CPU and memory are not saturated, but `oc describe pod` shows eviction messages related to disk. What is the most likely underlying issue and appropriate remediation?

An administrator is designing a disaster recovery approach for Cloud Pak for Data. They can back up only Kubernetes resources, not the underlying persistent storage snapshots. Which statement best describes what will be missing after a restore to a new cluster?

After installing Cloud Pak for Data, an administrator wants to verify that the platform is ready before deploying any services. Which action is the BEST initial validation step?

A cluster administrator must allow Cloud Pak for Data to pull images from a private container registry that requires authentication. What is the recommended approach?

An administrator needs to apply a corporate proxy configuration so Cloud Pak for Data components can access external endpoints for required connectivity. What is the BEST practice?

A Cloud Pak for Data administrator wants to give a data engineering team the ability to create and manage projects, but not manage cluster resources or platform-wide settings. Which role assignment is MOST appropriate?

A company requires that Cloud Pak for Data user access be controlled centrally. They want to disable local user management and use their corporate directory for authentication and group membership. What should the administrator implement?

Users report that Cloud Pak for Data is reachable, but some service pages load slowly or fail intermittently. The administrator suspects resource pressure. Which set of checks is MOST relevant to confirm or refute this hypothesis?

A service deployment on Cloud Pak for Data fails during reconciliation. The operator shows repeated retries and the service custom resource status indicates a missing prerequisite. What is the BEST next step for troubleshooting?

A team wants to integrate Cloud Pak for Data with an external object storage system for project data and artifacts. Which approach is MOST appropriate from an administrator perspective?

A Cloud Pak for Data deployment must meet strict security requirements: all external access must terminate TLS at the edge, and internal service-to-service communication should remain encrypted where supported. Which design is MOST aligned with best practices?

After a platform change, multiple CPD pods are stuck in Pending state. Events show that pods cannot be scheduled due to a mix of taints and insufficient resources on eligible nodes. What is the BEST remediation strategy that minimizes risk?

An administrator needs to verify that required cluster resources (operators, namespaces, and operands) for IBM Cloud Pak for Data are present before installing any services. Which approach is the MOST appropriate?

A Cloud Pak for Data environment must ensure that user permissions are centrally governed and changes are reflected quickly across the platform. Which identity approach best supports this requirement?

A service deployment fails with an error indicating that the container images cannot be pulled from the registry. The cluster nodes have outbound connectivity restrictions. What is the BEST next step to resolve this?

A platform team wants Cloud Pak for Data to use a dedicated StorageClass for all service persistent volumes to meet performance and encryption requirements. What is the RECOMMENDED way to achieve this?

After integrating LDAP, users can log in but do not see expected projects or services. The administrator confirmed the LDAP group exists. What should the administrator do NEXT to grant access correctly?
