Question 1

NVIDIA's CUDA architecture uses a hierarchy of threads. Which is the correct ordering from smallest to largest grouping?

Accepted Answer

Thread → Warp → Block → Grid

Answer

CUDA organizes threads into warps (32 threads), warps into blocks, and blocks into a grid, forming the complete hierarchy for GPU parallel execution.

Question 2

What advantage does NVIDIA's Confidential Computing feature on H100 provide for data center tenants?

Accepted Answer

It protects GPU workloads and data from privileged software attacks using hardware-based Trusted Execution Environments

Answer

H100 Confidential Computing uses hardware TEEs to protect AI workloads and model weights even from the hypervisor, cloud operator, or other privileged system software.

Question 3

Which NVIDIA data center GPU is specifically optimized for inference workloads with a balance of INT8 performance and low power consumption?

Accepted Answer

L4 (Ada Lovelace)

Answer

The L4 is based on Ada Lovelace architecture and is designed for energy-efficient inference, video AI, and graphics workloads with a 72W TDP.

Question 4

A company wants to deploy GPU-accelerated Kubernetes workloads. Which NVIDIA component enables GPUs to be scheduled as resources within Kubernetes?

Accepted Answer

NVIDIA GPU Operator

Answer

The NVIDIA GPU Operator automates the deployment and management of GPU software components (drivers, CUDA, device plugin) needed for GPU-accelerated Kubernetes workloads.

Question 5

What is the primary function of NVIDIA TensorRT in a data center inference pipeline?

Accepted Answer

Optimizes and compiles trained neural network models for high-throughput, low-latency GPU inference

Answer

TensorRT takes a trained model and applies optimizations like layer fusion, precision calibration (INT8/FP16), and kernel auto-tuning to maximize inference throughput on NVIDIA GPUs.
