Practice Questions: Configuring Networking for Cluster Nodes, DPUs, and Switches
This set of multiple-choice questions is designed to help candidates prepare for the Installation and Deployment section of the NVIDIA-Certified Professional: AI Operations exam, focusing specifically on configuring networking for cluster nodes, Data Processing Units (DPUs), and switches.
Which tool within Base Command Manager (BCM) Base View is primarily used to visualize and monitor network connectivity between cluster nodes and DPUs?
- A. Job Scheduler Dashboard
- B. Network Topology Viewer
- C. Firmware Update Manager
- D. User Role Administration Panel
Correct answer: B
Explanation: The Network Topology Viewer in BCM Base View provides a graphical representation of the network connections between cluster nodes, DPUs, and switches, enabling administrators to monitor and diagnose connectivity issues effectively.
When configuring networking for DPUs in an NVIDIA AI cluster, which of the following protocols is essential for enabling communication between DPUs and the host nodes?
- A. NVMe over Fabrics (NVMe-oF)
- B. Remote Direct Memory Access (RDMA)
- C. Simple Network Management Protocol (SNMP)
- D. File Transfer Protocol (FTP)
Correct answer: B
Explanation: RDMA is critical for high-performance, low-latency communication between DPUs and host nodes, allowing direct memory access without CPU involvement, which is essential in AI workloads.
Which of the following is the recommended method to ensure firmware consistency across all switches in an NVIDIA AI cluster?
- A. Manually update each switch via SSH
- B. Use BCM’s image synchronization feature
- C. Rely on automatic updates from the switch vendor
- D. Update firmware only when network issues occur
Correct answer: B
Explanation: BCM’s image synchronization automates and centralizes firmware updates across all switches, ensuring consistency and reducing the risk of configuration drift.
In the context of configuring cluster networking, what is the primary role of the NVIDIA DOCA Services deployed on DPUs?
- A. To provide user authentication and role management
- B. To enable offloading of networking and security functions from the host CPU
- C. To schedule AI jobs across cluster nodes
- D. To monitor GPU utilization metrics
Correct answer: B
Explanation: DOCA Services on DPUs offload networking, security, and telemetry tasks from the host CPU, improving overall cluster performance and security.
Which networking configuration step is essential when integrating Kubernetes with NVIDIA AI cluster nodes to ensure proper communication with DPUs?
- A. Disabling all firewalls on cluster nodes
- B. Configuring Kubernetes network plugins to support DPU passthrough
- C. Installing Slurm alongside Kubernetes
- D. Assigning static IP addresses only to GPU nodes
Correct answer: B
Explanation: Kubernetes network plugins must be configured to support DPU passthrough, enabling seamless communication and management of DPUs within Kubernetes-managed clusters.
What is the best practice for diagnosing network latency issues between cluster nodes and switches in an NVIDIA AI Operations environment?
- A. Restart all cluster nodes simultaneously
- B. Use BCM Base View to analyze network traffic and identify bottlenecks
- C. Disable DPUs temporarily to isolate the problem
- D. Increase the number of scheduled jobs to test network load
Correct answer: B
Explanation: BCM Base View provides detailed network traffic analytics and visualization tools that help identify latency sources and bottlenecks without disrupting cluster operations.
Which user permission in BCM is required to modify network configurations for cluster nodes and DPUs?
- A. Read-only User
- B. Network Administrator
- C. Job Scheduler
- D. Firmware Manager
Correct answer: B
Explanation: The Network Administrator role in BCM has the necessary permissions to configure and manage network settings for cluster nodes, DPUs, and switches.
