Q1. Which API group manages the DataScienceCluster custom resource definition in an OpenShift cluster?
Answer: A. datasciencecluster.opendatahub.io
The DataScienceCluster custom resource definition belongs to the datasciencecluster.opendatahub.io API group. It acts as the primary configuration hub for managing platform components within the cluster.
Q2. When configuring custom notebook images, what mandatory setting tells OpenShift AI which software stack is inside the image?
Answer: C. Software type categories and labels
Software packages and their version labels must be specified to define the software stack within the custom notebook image. This metadata helps users identify the available libraries when selecting workbench environments, whereas the other options only define basic deployment details.
Q3. What happens to scheduled pipeline runs when the pipeline server is deleted and recreated?
Answer: B. Scheduled runs configuration are preserved if external database persistent storage exists
Scheduled pipeline runs and their configurations are preserved when using an external database with persistent storage. If persistence is not configured, deleting the pipeline server destroys the runs, making database configuration critical for recovery.
Q4. Which custom resource allows you to configure cluster-wide default notebook sizes?
Answer: D. DataScienceCluster
The DataScienceCluster custom resource manages cluster-wide OpenShift AI features and feature toggles. On current versions, notebook size limits are often set per namespace using component-specific configurations, making this wording slightly ambiguous.
Q5. Which file format is used to import an externally generated pipeline definition into the OpenShift AI Pipelines UI?
Answer: B. Tekton YAML or Kubeflow Pipelines Tekton TAR.GZ file
OpenShift AI Data Science Pipelines natively consume compiled pipeline definitions packaged as TAR.GZ files. Direct Python scripts or standard Dockerfiles cannot be imported directly into the Pipelines UI without compilation.
Q6. Which system monitors and visualizes algorithmic drift or bias using OpenShift AI metrics data?
Answer: A. TrustyAI operator metrics engines dashboards platforms
The TrustyAI operator evaluates model bias and drift using OpenShift AI metrics data. It specifically integrates with model servers to provide fairness and explainability metrics, which Prometheus or Jaeger do not calculate natively.
Q7. What specific software layer allows Jupyter workbenches to leverage underlying NVIDIA GPU hardware configurations inside an OpenShift cluster?
Answer: D. The NVIDIA GPU Operator combined with the OpenShift AI Accelerator Profile configurations
The NVIDIA GPU Operator handles provisioning the necessary drivers and runtime components onto cluster nodes. OpenShift AI then uses Accelerator Profiles to expose these hardware resources correctly to Jupyter workbenches.
Q8. Which utility verifies the underlying integrity of OpenShift AI pipeline runs by storing structured history execution steps in a backend database?
Answer: B. MLMD (Machine Learning Metadata) server stack
The Machine Learning Metadata server records pipeline execution artifacts, components, and structural history in its backend database. Fluentd and Prometheus handle cluster logging and metrics rather than pipeline lineage tracking.
Q9. Which system component validates the structural integrity and prerequisite setup parameters of a cluster before OpenShift AI initializes?
Answer: A. The DSCInitialization component controller
The DSCInitialization controller validates cluster prerequisites and prepares the environment before applying Data Science Cluster configurations. Container runtimes and subscription agents do not validate OpenShift AI resource requirements.
Q10. Which framework component handles the visual presentation layer of the OpenShift AI administrative console interface?
Answer: A. odh-dashboard component
The odh-dashboard component handles the visual presentation layer of the administrative console. For the exam, focus on configuring and troubleshooting the dashboard rather than its internal React architecture, but know this component manages the interface.
Q11. What is the default visual tool used within OpenShift AI Jupyter notebooks for building machine learning pipelines without writing code?
Answer: D. Elyra Architecture
Elyra is the default visual editor in OpenShift AI Jupyter environments used to build pipeline architectures without code. Tekton Dashboard operates outside the notebook interface and is not the default layout tool.
Q12. What label is typically applied to nodes intended exclusively for machine learning workloads in OpenShift AI?
Answer: B. opendatahub.io/workload-type=ai
While node labels are highly customizable, the intended answer uses the OpenDataHub namespace convention for workload isolation. Be prepared to configure specific node selectors or tolerations during the exam to target GPU or dedicated worker nodes.
Q13. Which configuration format is natively expected when defining custom environment variables via a Secret key reference in an Elyra pipeline?
Answer: C. YAML or Key-Value
Secrets linked to workbenches or pipelines use standard key-value pairs to map data to environment variables. JSON, XML, and TOML require additional parsing logic, so Kubernetes natively expects simple key-value mappings for direct environment variable injection.
Q14. Which environment variable secret definition style should be used to protect a database password needed by a notebook workbench?
Answer: C. Referencing an existing OpenShift Secret within the workbench configuration
Referencing an OpenShift Secret is the standard Kubernetes approach for injecting sensitive credentials securely into a workbench. Storing passwords directly in plain text or inside custom container images is highly insecure and violates basic practices.
Q15. Which network policy control is needed to isolate an OpenShift AI project from other cluster namespaces?
Answer: D. NetworkPolicy CRD rules restricting cross-namespace ingress
NetworkPolicy CRD rules restrict cross-namespace ingress, isolating OpenShift AI projects from other cluster namespaces. Standard namespace isolation relies on these policies rather than hardware or DNS configurations.
Q16. Which metric framework is natively used by OpenShift AI to monitor model performance and cluster resource utilization?
Answer: A. Grafana and Prometheus
OpenShift uses Prometheus and Grafana for cluster and model monitoring. While the exam focuses heavily on model serving metrics, knowing the underlying default dashboard stack is useful for basic troubleshooting.
Q17. What configuration tracks custom workbench images added via the OpenShift AI dashboard?
Answer: D. Dashboard custom configuration image settings specifications
Custom workbench images are tracked through the dashboard custom configuration settings. Expect to use this interface when adding specialized notebook images. Note that the exact resource is the OdhDashboardConfig custom resource.
