Q1. To mount persistent storage across multiple workbenches simultaneously in a Data Science Project, what volume access mode is required?
Answer: B. ReadWriteMany (RWX)
ReadWriteMany allows the persistent volume to be mounted by multiple workbenches simultaneously. ReadWriteOnce restricts access to a single pod, preventing concurrent multi-user access required for shared storage.
Q2. What happens if a user requests 2 GPUs for a workbench, but the cluster only has nodes with 1 GPU each?
Answer: A. The workbench pod remains in a Pending status state due to unschedulable resources
When a workbench requests resources that exceed what is available, the pod remains in a Pending state because the scheduler cannot find a suitable node. OpenShift will not silently fall back to regular CPU units when an explicit GPU allocation fails.
Q3. Which tool within OpenShift allows administrators to view GPU compute metrics, temperature, and memory utilization?
Answer: A. Prometheus and Grafana via the NVIDIA GPU Operator dashboards
The NVIDIA GPU Operator integrates with Prometheus and Grafana to provide dashboards for GPU metrics, memory, and temperature. The OpenShift AI dashboard manages pipelines, but it does not natively monitor hardware metrics.
Q4. Which object specifies the amount of CPU and memory assigned to a data science workbench?
Answer: A. ContainerSize
The ContainerSize parameter directly defines the CPU and memory resource limits allocated to a workbench container. Resource quotas and limit ranges apply broad constraints across a namespace rather than defining specific workbench sizes.
Q5. What happens if an OpenShift AI pipeline exceeds its defined resource limits during execution?
Answer: C. The specific pipeline step pod is terminated with an OOMKilled error
The pod running the pipeline step gets terminated with an OOMKilled error when it breaches its configured memory limits. Kubernetes enforces these hard limits, so the pod cannot ignore them or automatically scale the underlying worker node CPU.
Q6. WHAT MANAGEMENT COMPONENT FACILITATES LOGIC GENERATION FOR CONFIGURING ACCELERATORS LIKE NVIDIA GPUS?
Answer: C. Node Feature Discovery (NFD) Operator
The Node Feature Discovery Operator labels nodes with hardware accelerators like NVIDIA GPUs. The OpenShift AI Operator relies on these labels to schedule workbench or inference pods onto the correct compute nodes.
Q7. WHAT APPLICATION CONTAINS JUPYTERBOOKS AND DATA SCIENCE WORKBENCHES BY DEFAULT IN RHOAI?
Answer: C. OpenShift AI Dashboard
The OpenShift AI Dashboard serves as the primary interface for launching Jupyter notebooks and data science workbenches. Standard OpenShift web consoles do not provide these specialized machine learning interfaces by default.
Q8. Which format does the Elyra pipeline editor export workflows into for native execution on the OpenShift AI pipeline server?
Answer: B. Tekton PipelineRun YAML or Tekton format
The Elyra pipeline editor exports visual workflows into Tekton PipelineRun YAML formats for execution. Because OpenShift AI Pipelines natively rely on Tekton, Argo or Jenkins formats will not execute natively.
Q9. WHAT TOOL INSIDE OPENSHIFT AI VISUALLY BUILDS AND SUBMITS DATA SCIENCE PIPELINES?
Answer: C. Elyra Pipeline Editor
The Elyra Pipeline Editor is the visual tool integrated into Jupyter workbenches for building and submitting pipelines. It is explicitly designed to generate the required Tekton YAML for the underlying pipeline engine.
Q10. Which component validates the correct reconciliation process of the DataScienceCluster custom resource manifest?
Answer: C. Data Science Cluster Controller Manager pod
The Data Science Cluster Controller Manager pod handles the reconciliation of the DataScienceCluster custom resource. This controller ensures the requested OpenShift AI components are properly deployed and maintained.
Q11. Which command confirms that the Red Hat OpenShift AI Operator is successfully running?
Answer: B. oc get csv -n redhat-ods-operator
Checking the ClusterServiceVersion or CSV confirms the operator was installed successfully via OperatorHub. This command displays the installation phase and verifies the operator is resolving correctly.
Q12. Which sub-component within OpenShift AI manages the authentication wrapper that secures access to Jupyter notebook instances?
Answer: B. OpenShift OAuth Proxy
The OpenShift OAuth Proxy acts as the authentication wrapper securing access to workbench instances. It integrates directly with OpenShift OAuth to ensure only authorized users can reach the notebooks.
Q13. What component handles user session redirection upon clicking launch inside the OpenShift AI dashboard?
Answer: B. OpenShift OAuth Proxy
The OpenShift OAuth Proxy handles user authentication and session redirection when accessing workbenches. Other identity brokers like Keycloak are distractors not directly integrated into dashboard launches.
Q14. WHAT IS THE PRIMARY CUSTOM RESOURCE USED TO MANAGE WORKBENCH INSTANCES FOR DATA SCIENTISTS?
Answer: C. Notebook
The Notebook custom resource manages workbench instances for data scientists. While Workbench sounds correct, the underlying Kubernetes object used by the operator is the Notebook CR.
Q15. What is the primary objective of a Data Science Project in the Red Hat OpenShift AI dashboard?
Answer: C. To act as an isolated Kubernetes namespace with managed access controls and project-specific resources
A Data Science Project acts as an isolated Kubernetes namespace with managed access controls. It organizes resources like workbenches and pipelines rather than handling CI/CD builds or physical node allocation.
Q16. WHICH SERVICE DISCOVERS AND APPLIES LABELS FOR SPECIFIC HARDWARE ACCELERATORS ON NODES?
Answer: C. Node Feature Discovery (NFD)
Node Feature Discovery detects specific hardware accelerators on nodes and applies the appropriate labels. The NVIDIA GPU Operator uses these labels, but NFD is the service that actually discovers and applies them.
Q17. To share a custom python function as a reusable pipeline component, which framework is most commonly integrated with RHOAI pipelines?
Answer: D. Kubeflow Pipelines SDK
The Kubeflow Pipelines SDK is the primary framework for creating reusable components in OpenShift AI data science pipelines. Ansible or AMQ Streams handle unrelated automation tasks.
