NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q21-Q26):
NEW QUESTION # 21
During AI model deployment, your team notices significant performance degradation in inference workloads.
The model is deployed on an NVIDIA GPU cluster with Kubernetes. Which of the following could be the most likely cause of the degradation?
- A. Outdated CUDA drivers
- B. Insufficient GPU memory allocation
- C. CPU bottlenecks
- D. High disk I/O latency
Answer: B
Explanation:
Insufficient GPU memory allocation is the most likely cause of inference degradation in a Kubernetes- managed NVIDIA GPU cluster. Memory shortages lead to swapping or failures, slowing performance. Option A (outdated CUDA) may cause compatibility issues, not direct degradation. Option B (CPU bottlenecks) affects preprocessing, not inference. Option C (disk I/O) impacts data loading, not GPU tasks. NVIDIA's Kubernetes GPU Operator docs stress memory allocation.
NEW QUESTION # 22
Which networking feature is most important for supporting distributed training of large AI models across multiple data centers?
- A. Implementation of Quality of Service (QoS) policies to prioritize AI training traffic
- B. Deployment of wireless networking to enable flexible node placement
- C. Segregated network segments to prevent data leakage between AI tasks
- D. High throughput with low latency WAN links between data centers
Answer: D
Explanation:
High throughput with low latency WAN links between data centers is the most important networking feature for supporting distributed training of large AI models. Distributed training across multiple data centers requires rapid exchange of gradients and model parameters, which demands high-bandwidth, low-latency connections (e.g., InfiniBand or high-speed Ethernet over WAN). NVIDIA's "DGX SuperPOD Reference Architecture" and "AI Infrastructure for Enterprise" emphasize that network performance is critical for scaling AI training geographically, ensuring synchronization and minimizing training time.
QoS policies (B) prioritize traffic but don't address raw performance needs. Segregated segments (C) enhance security, not training efficiency. Wireless networking (D) lacks the reliability and bandwidth for data center AI. NVIDIA prioritizes high-throughput, low-latency networking for distributed training.
NEW QUESTION # 23
As a junior team member, you are tasked with running data analysis on a large dataset using NVIDIA RAPIDS under the supervision of a senior engineer. The senior engineer advises you to ensure that the GPU resources are effectively utilized to speed up the data processing tasks. What is the best approach to ensure efficient use of GPU resources during your data analysis tasks?
- A. Focus on using only CPU cores for parallel processing
- B. Disable GPU acceleration to avoid potential compatibility issues
- C. Use CPU-based pandas for all DataFrame operations
- D. Use cuDF to accelerate DataFrame operations
Answer: D
Explanation:
UsingcuDF to accelerate DataFrame operations(D) is the best approach to ensure efficient GPUresource utilization with NVIDIA RAPIDS. Here's an in-depth explanation:
* What is cuDF?: cuDF is a GPU-accelerated DataFrame library within RAPIDS, designed to mimic pandas' API but execute operations on NVIDIA GPUs. It leverages CUDA to parallelize data processing tasks (e.g., filtering, grouping, joins) across thousands of GPU cores, dramatically speeding up analysis on large datasets compared to CPU-based methods.
* Why it works: Large datasets benefit from GPU parallelism. For example, a join operation on a 10GB dataset might take minutes on pandas (CPU) but seconds on cuDF (GPU) due to concurrent processing.
The senior engineer's advice aligns with maximizing GPU utilization, as cuDF offloads compute- intensive tasks to the GPU, keeping cores busy.
* Implementation: Replace pandas imports with cuDF (e.g., import cudf instead of import pandas), ensuring data resides in GPU memory (via to_cudf()). RAPIDS integrates with other libraries (e.g., cuML) for end-to-end GPU workflows.
* Evidence: RAPIDS is built for this purpose-efficient GPU use for data analysis-making it the optimal choice under supervision.
Why not the other options?
* A (Disable GPU acceleration): Defeats the purpose of using RAPIDS and GPUs, slowing analysis.
* B (CPU-based pandas): Limits performance to CPU capabilities, underutilizing GPU resources.
* C (CPU cores only): Ignores the GPU entirely, contradicting the task's intent.
NVIDIA RAPIDS documentation endorses cuDF for GPU efficiency (D).
NEW QUESTION # 24
Which solution should be recommended to support real-time collaboration and rendering among a team?
- A. A cluster of servers with NVIDIA T4 GPUs in each server.
- B. A DGX SuperPOD.
- C. An NVIDIA Certified Server with RTX-based GPUs.
Answer: C
Explanation:
An NVIDIA Certified Server with RTX GPUs is optimized for real-time collaboration and rendering, supporting NVIDIA Virtual Workstation (vWS) software. This setup enables low-latency, multi-user graphics workloads, ideal for team-based design or visualization. T4 GPUs focus on inference efficiency, and DGX SuperPOD targets large-scale AI training, not collaborative rendering.

NEW QUESTION # 25
An IT professional is considering whether to implement an on-prem or cloud infrastructure. Which of the following is a key advantage of on-prem infrastructure?
- A. Easy remote management.
- B. Ensure data security and sovereignty.
- C. Scalability and flexibility.
- D. Lower upfront costs and capital expenditure.
Answer: B
Explanation:
On-premises infrastructure offers a key advantage in ensuring data security and sovereignty, as organizations retain direct control over hardware and data, facilitating compliance with strict regulations (e.g., GDPR).
Cloud solutions excel in scalability and lower upfront costs, but on-prem provides unmatched authority over sensitive data, outweighing remote management ease in security-critical scenarios.
