NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q174-Q179):

NEW QUESTION # 174
You are managing an AI infrastructure where multiple AI workloads are being run in parallel, including image recognition, natural language processing (NLP), and reinforcement learning. Due to limited resources, you need to prioritize these workloads. Which AI workload should you prioritize first to ensure the best overall system performance and resource allocation?

A. Reinforcement learning
B. Image recognition
C. Natural Language Processing (NLP)
D. Background data preprocessing

Answer: C

Explanation:
Natural Language Processing (NLP) should be prioritized first to ensure the best overall system performance and resource allocation in this scenario. NLP workloads, such as large language models (e.g., BERT, GPT), are typically compute- and memory-intensive, benefiting significantly from NVIDIA GPUs' parallel processing capabilities (e.g., Tensor Cores). Prioritizing NLP ensures efficient resource use for a high-impact workload, as noted in NVIDIA's "AI Infrastructure and Operations Fundamentals" and "Deep Learning Institute (DLI)" materials, which highlight NLP's growing enterprise demand and GPU optimization.
Image recognition (A) and reinforcement learning (B) are also GPU-intensive but often less resource- constrained than NLP in mixed workloads. Background preprocessing (D) is less time-sensitive and can run opportunistically. NVIDIA's workload prioritization guidance favors NLP in such cases.

NEW QUESTION # 175
In an AI infrastructure setup, you need to optimize the network for high-performance data movement between storage systems and GPU compute nodes. Which protocol would be most effective for achieving low latency and high bandwidth in this environment?

A. SMTP
B. TCP/IP
C. Remote Direct Memory Access (RDMA)
D. HTTP

Answer: C

Explanation:
Remote Direct Memory Access (RDMA) is the most effective protocol for optimizing network performance between storage systems and GPU compute nodes in an AI infrastructure. RDMA enables direct memory access between devices over high-speed interconnects (e.g., InfiniBand, RoCE), bypassing the CPU and reducing latency while providing high bandwidth. This is critical for AI workloads, where large datasets must move quickly to GPUs for training or inference, minimizing bottlenecks.
HTTP (A) and SMTP (B) are application-layer protocols for web and email, respectively, unsuitable for low- latency data movement. TCP/IP (D) is a general-purpose networking protocol but lacks the performance of RDMA for GPU-centric workloads. NVIDIA's "DGX SuperPOD Reference Architecture" and "AI Infrastructure and Operations" materials highlight RDMA's role in high-performance AI networking.

NEW QUESTION # 176
You are assisting in a project that involves deploying a large-scale AI model on a multi-GPU server. The server is experiencing unexpected performance degradation during inference, and you have been asked to analyze the system under the supervision of a senior engineer. Which approach would be most effective in identifying the source of the performance degradation?

A. Monitor the system's power supply levels.
B. Analyze the GPU memory usage using nvidia-smi.
C. Check the system's CPU utilization.
D. Inspect the training data for inconsistencies.

Answer: B

Explanation:
Analyzing GPU memory usage with nvidia-smi is the most effective approach to identify performance degradation during inference on a multi-GPU server. NVIDIA's nvidia-smi tool provides real-time insights into GPU utilization, memory usage, and process activity, pinpointing issues like memory overflows, underutilization, or contention-common causes of inference slowdowns. Option A (power supply) is secondary, as power issues typically cause failures, not gradual degradation. Option B (CPU utilization) is relevant but less critical for GPU-bound inference tasks. Option D (training data) affects model quality, not runtime performance. NVIDIA's performance troubleshooting guides recommend nvidia-smi as a primary diagnostic tool for GPU-based workloads.

NEW QUESTION # 177
A financial services company is using an AI model for fraud detection, deployed on NVIDIA GPUs. After deployment, the company notices a significant delay in processing transactions, which impacts their operations. Upon investigation, it's discovered that the AI model is being heavily used during peak business hours, leading to resource contention on the GPUs. What is the best approach to address this issue?

A. Implement GPU load balancing across multiple instances
B. Switch to using CPU resources instead of GPUs for processing
C. Disable GPU monitoring to free up resources
D. Increase the batch size of input data for the AI model

Answer: A

Explanation:
Implementing GPU load balancing across multiple instances is the best approach to address resource contention and delays in a fraud detection system during peak hours. Load balancing distributes inference workloads across multiple NVIDIA GPUs (e.g., in a DGX cluster or Kubernetes setup with Triton Inference Server), ensuring no single GPU is overwhelmed. This maintains low latency and high throughput, as recommended in NVIDIA's "AI Infrastructure and Operations Fundamentals" and "Triton Inference Server Documentation" for production environments.
Switching to CPUs (A) sacrifices GPU performance advantages. Disabling monitoring (B) doesn't address contention and hinders diagnostics. Increasing batch size (C) may worsen delays by overloading GPUs. Load balancing is NVIDIA's standard solution for peak load management.

NEW QUESTION # 178
You are tasked with deploying multiple AI workloads in a data center that supports both virtualized and non- virtualized environments. To maximize resource efficiency and flexibility, which of the following strategies would be most effective for running AI workloads in a virtualized environment?

A. Use a single VM to run all AI workloads sequentially, reducing the need for resource scheduling
B. Run all AI workloads on bare metal servers without virtualization to maximize performance
C. Use containerization within a single VM to run multiple AI workloads, leveraging shared resources efficiently
D. Deploy each AI workload in a separate virtual machine (VM) to isolate resources and prevent interference

Answer: C

Explanation:
Using containerization within a single VM to run multiple AI workloads is the most effective strategy for maximizing resource efficiency and flexibility in a virtualized environment. Containers (e.g., Docker) allow multiple workloads to share GPU resources via NVIDIA's container runtime, offering lightweight isolation and efficient resource utilization compared to separate VMs. This approach, supported by NVIDIA's
"DeepOps" and "GPU Virtualization" documentation, leverages Kubernetes or similar orchestration for scalability and flexibility while maintaining performance on virtualized GPUs (e.g., via NVIDIA GPU Operator).
Separate VMs (B) waste resources due to overhead. Sequential execution in one VM (C) sacrificesparallelism, reducing efficiency. Bare metal (D) maximizes performance but lacks virtualization flexibility. NVIDIA recommends containerization for virtualized AI efficiency.
