Key topics also involve explaining the factors behind AI's rapid adoption, identifying major AI use cases across industries, and describing the purpose of various NVIDIA solutions. The section requires knowledge of the software components in the AI development lifecycle and an ability to contrast GPU and CPU architectures.

Topic 2

AI Infrastructure: This section of the exam measures the skills of IT professionals and focuses on the physical and architectural components needed for AI. It involves understanding the process of extracting insights from large datasets through data mining and visualization. Candidates must be able to compare models using statistical metrics and identify data trends. The infrastructure knowledge extends to data center platforms, energy-efficient computing, networking for AI, and the role of technologies like NVIDIA DPUs in transforming data centers.

Topic 3

AI Operations: This section of the exam measures the skills of data center operators and encompasses the management of AI environments. It requires describing essentials for AI data center management, monitoring, and cluster orchestration. Key topics include articulating measures for monitoring GPUs, understanding job scheduling, and identifying considerations for virtualizing accelerated infrastructure. The operational knowledge also covers tools for orchestration and the principles of MLOps.

NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q19-Q24):

NEW QUESTION # 19
You are managing an AI infrastructure that includes multiple NVIDIA GPUs across various virtual machines (VMs) in a cloud environment. One of the VMs is consistently underperforming compared to others, even though it has the same GPU allocation and is running similar workloads.What is the most likely cause of the underperformance in this virtual machine?

A. Inadequate storage I/O performance
B. Incorrect GPU driver version installed
C. Insufficient CPU allocation for the VM
D. Misconfigured GPU passthrough settings

Answer: D

Explanation:
In a virtualized cloud environment with NVIDIA GPUs, underperformance in one VM despite identical GPU allocation suggests a configuration issue. Misconfigured GPU passthrough settings-where the GPU isn't directly accessible to the VM due to improper hypervisor setup (e.g., PCIe passthrough in KVM or VMware)
-is the most likely cause. NVIDIA's vGPU or passthrough documentation stresses correct configuration for full GPU performance; errors here limit the VM's access to GPU resources, causing slowdowns.
Inadequate storage I/O (Option B) or CPU allocation (Option C) could affect performance but would likely impact all VMs similarly if uniform. An incorrect GPU driver (Option D) might cause failures, not just underperformance, and is less likely in a managed cloud. Passthrough misalignment is a common NVIDIA virtualization issue.

NEW QUESTION # 20
When virtualizing an infrastructure that includes GPUs to support AI workloads, what is one critical factor to consider to ensure optimal performance?

A. Assign more storage to each virtual machine
B. Disable hyper-threading on the host machine
C. Use GPU sharing technologies, like NVIDIA GRID, to allocate resources dynamically
D. Increase the number of virtual CPUs assigned to each VM

Answer: C

Explanation:
Using GPU sharing technologies like NVIDIA GRID (A) is a critical factor for optimal performance in a virtualized AI infrastructure. NVIDIA GRID (or its successor, NVIDIA vGPU) enables dynamic allocation of GPU resources across virtual machines (VMs), allowing multiple AI workloads to share a physical GPU efficiently. This ensures high performance by providing each VM with direct GPU acceleration tailored to its needs, while maximizing resource utilization-keyfor AI tasks like training or inference.
* Assigning more storage(B) improves I/O but doesn't directly enhance GPU performance for compute- heavy AI workloads.
* Increasing virtual CPUs(C) boosts CPU capacity, but AI workloads rely primarily on GPU acceleration, not vCPUs.
* Disabling hyper-threading(D) might reduce CPU contention but doesn't address GPU virtualization needs.
NVIDIA's virtualization documentation emphasizes vGPU/GRID for AI performance (A).

NEW QUESTION # 21
You are working on deploying a deep learning model that requires significant GPU resources across multiple nodes. You need to ensure that the model training is scalable, with efficient data transfer between the nodes to minimize latency. Which of the following networking technologies is most suitable for this scenario?

A. Ethernet (1 Gbps)
B. InfiniBand
C. Fiber Channel
D. Wi-Fi 6

Answer: B

Explanation:
InfiniBand (C) is the most suitable networking technology for scalable, low-latency data transfer in multi- node GPU training. It offers high throughput (up to 400 Gbps) and ultra-low latency (<1 µs), ideal for synchronizing gradients and weights across nodes using NVIDIA NCCL. InfiniBand's RDMA (Remote Direct Memory Access) further enhances efficiency by bypassing CPU overhead, critical for distributed deep learning.
* Wi-Fi 6(A) lacks the reliability and bandwidth (max ~10 Gbps) for training clusters.
* Fiber Channel(B) is for storage, not compute node interconnects.
* Ethernet (1 Gbps)(D) is too slow for large-scale AI training demands.
NVIDIA's DGX systems use InfiniBand for this purpose (C).

NEW QUESTION # 22
Your team is building an AI-powered application that requires the deployment of multiple models, each trained using different frameworks (e.g., TensorFlow, PyTorch, and ONNX). You need a deployment solution that can efficiently serve all these models in production, regardless of the framework they were built in.
Which software component should you choose?

A. NVIDIA Triton Inference Server
B. NVIDIA TensorRT
C. NVIDIA DeepOps
D. NVIDIA Clara Deploy SDK

Answer: A

Explanation:
NVIDIA Triton Inference Server is the best choice for deploying multiple models from different frameworks (TensorFlow, PyTorch, ONNX) in production. Triton provides a unified platform for serving models, supporting diverse frameworks with high performance on NVIDIA GPUs via features like dynamic batching and multi-model management. Option A (Clara Deploy SDK) is healthcare-specific. Option B (TensorRT) optimizes inference but isn't a full serving solution. Option C (DeepOps) aids deployment automation, not model serving. NVIDIA's Triton documentation emphasizes its versatility and efficiency for production inference across frameworks.

NEW QUESTION # 23
You are assisting a professional administrator in ensuring data integrity during AI model training in an AI data center. Which of the following strategies would best contribute to maintaining data integrity across distributed GPU nodes?

A. Assign data verification tasks to DPUs, allowing GPUs to focus solely on model training
B. Use a single master node with GPUs to manage all data processing and then distribute the results to other nodes
C. Utilize redundant GPU nodes to independently process data and compare results post-training
D. Implement a distributed file system with replication, ensuring that each GPU node has access to the same consistent dataset

Answer: D

Explanation:
Implementing a distributed file system with replication (e.g., GPFS, Lustre) is the best strategy to maintain data integrity across distributed GPU nodes during AI model training. This ensures allnodes access a consistent, replicated dataset, preventing corruption or discrepancies that could skew training results.
NVIDIA's "DGX SuperPOD Reference Architecture" and "AI Infrastructure and Operations Fundamentals" recommend distributed file systems for data consistency in multi-node GPU clusters, supporting scalability and fault tolerance.
A single master node (A) risks bottlenecks and single-point failures. DPUs for verification (B) offload networking, not data integrity tasks. Redundant processing (C) is inefficient and post-hoc. NVIDIA's guidance favors distributed file systems for integrity.

NEW QUESTION # 24
