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

During upgrade planning for IBM Cloud Pak for Data, an administrator must confirm the cluster can support the target deployment before any changes are made. Which activity is the best first step to reduce upgrade risk?

An environment uses OpenShift with multiple storage classes. Cloud Pak for Data services require a file-based ReadWriteMany (RWX) volume for shared components. Which storage choice best meets this requirement?

A team is upgrading and wants to ensure that only the intended namespaces and operators are modified. Which approach aligns best with least-privilege and controlled change practices?

After the upgrade, several workloads show intermittent failures because pods cannot resolve internal service names. Which component should be checked first to troubleshoot cluster-wide name resolution issues?

An administrator performs an upgrade and notices the Cloud Pak for Data platform operators are installed, but service operators for certain capabilities never reconcile and remain in a pending state. Logs indicate the subscription is not receiving updates. What is the most likely cause?

A customer is moving to new storage during an upgrade and must preserve persistent data for Cloud Pak for Data services. Which practice is most appropriate to minimize data loss risk?

After upgrading, the web UI is accessible but some service tiles show 'Not ready' even though pods are running. Which action is the best next step to identify the root cause?

A cluster has strict egress controls, and the upgrade requires pulling operator bundles and images from internal mirrors. Which configuration is most important to ensure nodes and operators use the mirrored content rather than external registries?

During an in-place upgrade, an administrator changes the cluster-level security settings and later finds that some upgraded services fail to start due to SCC/PSA restrictions (for example, needing specific fsGroup or supplemental groups). What is the best way to handle this while maintaining security posture?

A company plans to upgrade Cloud Pak for Data in a regulated environment and must ensure they can roll back if post-upgrade validation fails. Which strategy provides the most reliable rollback capability for platform and data together?

During an IBM Cloud Pak for Data v4.x upgrade assessment, an administrator wants to identify whether any installed services are unsupported in the target release before starting the upgrade. Which approach is most appropriate?

A team is upgrading Cloud Pak for Data and wants to minimize risk by ensuring they can roll back if the upgrade introduces an issue. Which preparation best supports rollback and recovery?

After an upgrade, a user cannot access the Cloud Pak for Data web UI. The OpenShift route exists, but the browser shows a certificate mismatch warning and then fails to load. What is the most likely root cause?

An organization uses a private container registry and disconnected environment. During the upgrade, the cluster cannot pull new images for Cloud Pak for Data components. Which configuration is the BEST next step to resolve this?

A platform administrator plans to upgrade Cloud Pak for Data and is concerned about custom configuration changes made directly to Kubernetes Deployments for a service. What is the recommended practice to preserve customizations across operator-managed upgrades?

A customer is migrating analytics workloads to a new Cloud Pak for Data cluster while keeping the old cluster online temporarily. They must ensure project assets (notebooks, connections, and other metadata) are transferred with minimal user disruption. Which approach best meets this requirement?

After upgrading, several pods remain in CrashLoopBackOff. The container logs show repeated 'permission denied' errors when writing to a mounted volume. What is the MOST likely cause and best first action?

A team needs to upgrade Cloud Pak for Data in a highly regulated environment. They want a controlled rollout that minimizes downtime and ensures operators transition safely. Which strategy is MOST appropriate?

During an upgrade in a disconnected environment, the platform operator reports it cannot reconcile because it cannot resolve required operand versions from the catalog. The cluster uses an internal mirror registry. Which remediation is MOST accurate?

After migrating Cloud Pak for Data to a new cluster, users report that connections to external databases fail only from certain services, while other services can connect successfully. Network policies are in place. What is the BEST diagnostic approach to isolate the problem?

During an IBM Cloud Pak for Data upgrade, the platform team wants to reduce risk by validating the cluster is ready before any component changes occur. Which action is the best first step to identify upgrade blockers related to operators and custom resources?

After upgrading Cloud Pak for Data, a data engineer reports that their Spark-based workloads can no longer access object storage credentials that were previously injected automatically. Pods start but fail when trying to read from the bucket. What is the most likely cause?

A customer must upgrade Cloud Pak for Data but is required to keep user data and metadata intact. The environment uses persistent volumes and includes multiple services. Which approach best supports a rollback strategy if the upgrade fails?

A platform administrator is preparing for a Cloud Pak for Data upgrade and needs to ensure the cluster can handle the process without resource starvation. Which is the best practice to validate capacity before starting?

During post-upgrade validation, the Cloud Pak for Data web console is reachable but several service tiles show "Not ready". The operator pods are running, but the service custom resources are stuck in a reconciling state with repeated events indicating missing permissions. What is the most appropriate next action?
