An administrator plans to apply platform updates while minimizing user impact. Which approach aligns best with operational best practices?

Users report intermittent failures when accessing the Cloud Pak for Data UI through the external endpoint. Internal service-to-service traffic is stable. The administrator suspects an ingress issue. What is the best next diagnostic action?

A workload running in Cloud Pak for Data frequently gets evicted and re-scheduled. Node pressure events show memory pressure on specific worker nodes, even though cluster-wide memory utilization looks acceptable. What is the most effective corrective action?

A security team mandates strict network segmentation so that only approved namespaces can communicate with Cloud Pak for Data services, while still allowing required platform operations. Which design best meets this requirement?

After a storage maintenance event, multiple Cloud Pak for Data pods remain in Pending state. Events show persistent volume mount failures and timeouts. What is the most appropriate sequence to restore service with minimal disruption?

After installing Cloud Pak for Data, an administrator wants to reduce the chance of resource starvation for the platform’s control-plane services during heavy analytics workloads. Which approach is the best practice?

A new administrator needs to quickly verify whether the Cloud Pak for Data platform is generally healthy before onboarding more users. Which check is the most appropriate first step?

An organization integrates Cloud Pak for Data with an enterprise identity provider. They want users to authenticate with SSO and ensure group membership determines access inside Cloud Pak for Data with minimal manual administration. What is the best approach?

A user reports they can log in but cannot create a project. Other users can create projects successfully. What is the most likely cause?

An administrator must ensure that data scientists can access a specific S3 bucket from within Cloud Pak for Data, but must not allow them to view or modify the underlying credentials. Which method best satisfies this requirement?

During routine maintenance, an administrator needs to safely apply platform changes that require restarting certain services while minimizing user impact. Which approach is most appropriate?

A cluster uses an internal certificate authority. After a certificate rotation, multiple Cloud Pak for Data components show TLS handshake errors when calling internal endpoints. What is the best next step to restore service?

An administrator notices frequent pod evictions for user workloads due to memory pressure, while the platform services remain stable. Which action best improves workload stability without over-provisioning the entire cluster?

A Cloud Pak for Data deployment spans multiple worker nodes. A storage outage causes several services to enter a degraded state. After storage is restored, some pods remain stuck in a crash loop due to corrupted caches and repeated initialization failures. What is the safest remediation approach?

A security team requires that administrative actions in Cloud Pak for Data be traceable to individual users for audits. They also want to minimize the use of shared accounts. Which configuration best meets this requirement?

After installing IBM Cloud Pak for Data, an administrator wants to verify that the platform is ready for users to log in. Which check is the BEST first validation step?

A security team requires that user identities be centrally managed and that access can be revoked immediately when employees leave. Which approach BEST meets this requirement for Cloud Pak for Data user authentication?

An administrator needs to rotate a TLS certificate used by Cloud Pak for Data ingress without changing application configuration. Where should the updated certificate typically be placed in OpenShift?

A Cloud Pak for Data administrator wants to minimize downtime during planned node maintenance in the OpenShift cluster. Which OpenShift feature MOST directly supports safely moving Cloud Pak for Data workloads off a node?

Users report they can log in to Cloud Pak for Data, but they cannot create projects due to authorization errors. The administrator suspects group-to-role mapping is incorrect. What is the BEST next step?

A Cloud Pak for Data service install fails with an error indicating insufficient permissions for the operator to create resources in the operand namespace. What is the MOST likely cause?

An administrator wants to implement the principle of least privilege for day-to-day platform operations. Which approach is MOST appropriate?

A Cloud Pak for Data deployment is experiencing intermittent timeouts when users access the UI. Pod metrics show normal CPU/memory usage, but OpenShift indicates multiple pod restarts due to liveness probe failures. What is the BEST action to take first?

A company must ensure that sensitive configuration values used by Cloud Pak for Data services are not exposed in plaintext to users with read access to ConfigMaps. Which design is BEST practice?
