NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q50-Q55):

NEW QUESTION # 50
A global financial institution is implementing an AI-driven fraud detection system that must process vast amounts of transaction data in real-time across multiple regions. The system needs to be highly scalable, maintain low latency, and ensure data security and compliance with various international regulations. The infrastructure should also support continuous model updates without disrupting the service. Which combination of NVIDIA technologies would best meet the requirements for this fraud detection system?

  • A. Deploy the system on generic CPU-based servers with CUDA for accelerated computation.
  • B. Deploy the system on NVIDIA DGX A100 systems with NVIDIA Merlin for real-time data processing and model updates.
  • C. Implement the system on NVIDIA Quadro GPUs with TensorFlow for model training and deployment.
  • D. Use NVIDIA Jetson AGX Xavier devices for distributed data processing across regional offices.

Answer: B

Explanation:
Deploying on NVIDIA DGX A100 systems with NVIDIA Merlin best meets the requirements for ascalable, low-latency, secure fraud detection system with continuous updates. DGX A100 provides high-performance GPU compute (e.g., 5 petaFLOPS AI performance) for real-time processing and training, while Merlin accelerates recommendation and fraud detection workflows with real-time feature engineering and model updates, ensuring minimal disruption. Option A (Quadro GPUs) lacks the scalability of DGX. Option C (CPU- based with CUDA) underutilizes GPU potential. Option D (Jetson AGX) suits edge, not centralized, processing. NVIDIA's financial use case documentation supports this combination.


NEW QUESTION # 51
You are helping a senior engineer analyze the results of a hyperparameter tuning process for a machine learning model. The results include a large number of trials, each with different hyperparameters and corresponding performance metrics. The engineer asks you to create visualizations that will help in understanding how different hyperparameters impact model performance. Which type of visualization would be most appropriate for identifying the relationship between hyperparameters and model performance?

  • A. Scatter plot of hyperparameter values against performance metrics
  • B. Parallel coordinates plot showing hyperparameters and performance metrics
  • C. Line chart showing performance metrics over trials
  • D. Pie chart showing the proportion of successful trials

Answer: B

Explanation:
A parallel coordinates plot is ideal for visualizing relationships between multiple hyperparameters (e.g., learning rate, batch size) and performance metrics (e.g., accuracy) across many trials. Each axis represents a variable, and lines connect values for each trial, revealing patterns-like how a high learning rate might correlate with lower accuracy-across high-dimensional data. NVIDIA's RAPIDS library supports such visualizations on GPUs, enhancing analysis speed for large datasets.
A scatter plot (Option A) works for two variables but struggles with multiple hyperparameters. A pie chart (Option C) shows proportions, not relationships. A line chart (Option D) tracks trends over time or trials but doesn't link hyperparameters to metrics effectively. Parallel coordinates are NVIDIA-aligned for multi- variable AI analysis.


NEW QUESTION # 52
In your multi-tenant AI cluster, multiple workloads are running concurrently, leading to some jobs experiencing performance degradation. Which GPU monitoring metric is most critical for identifying resource contention between jobs?

  • A. Memory Bandwidth Utilization
  • B. GPU Temperature
  • C. GPU Utilization Across Jobs
  • D. Network Latency

Answer: C

Explanation:
GPU Utilization Across Jobs is the most critical metric for identifying resource contention in a multi-tenant cluster. It shows how GPU resources are divided among workloads, revealing overuse or starvation via tools like nvidia-smi. Option B (temperature) indicates thermal issues, not contention. Option C (network latency) affects distributed tasks. Option D (memory bandwidth) is secondary. NVIDIA's DCGM supports this metric for contention analysis.


NEW QUESTION # 53
Your AI data center is running multiple high-performance GPU workloads, and you notice that certain servers are being underutilized while others are consistently at full capacity, leading to inefficiencies. Which of the following strategies would be most effective in balancing the workload across your AI data center?

  • A. Increase cooling capacity in the data center
  • B. Implement NVIDIA GPU Operator with Kubernetes for automatic resource scheduling
  • C. Manually reassign workloads based on current utilization
  • D. Use horizontal scaling to add more servers

Answer: B

Explanation:
The NVIDIA GPU Operator with Kubernetes (C) automates resource scheduling and workload balancing across GPU clusters. It integrates GPU awareness into Kubernetes, dynamically allocating workloads to underutilized servers based on real-time utilization, priority, and resource demands. This ensures efficient use of all GPUs, reducing inefficiencies without manual intervention.
* Horizontal scaling(A) adds more servers, increasing capacity but not addressing the imbalance- underutilized servers would remain inefficient.
* Manual reassignment(B) is impractical for large-scale, dynamic workloads and lacks scalability.
* Increasing cooling capacity(D) improves hardware reliability but doesn't balanceworkloads.
The GPU Operator's automation and integration with Kubernetes make it the most effective solution (C).


NEW QUESTION # 54
After deploying an AI model on an NVIDIA T4 GPU in a production environment, you notice that the inference latency is inconsistent, varying significantly during different times of the day. Which of the following actions would most likely resolve the issue?

  • A. Upgrade the GPU driver.
  • B. Increase the number of inference threads.
  • C. Implement GPU isolation for the inference process.
  • D. Deploy the model on a CPU instead of a GPU.

Answer: C

Explanation:
Implementing GPU isolation for the inference process is the most likely solution to resolve inconsistent latency on an NVIDIA T4 GPU. In multi-tenant or shared environments, other workloads may interfere with the GPU, causing resource contention and latency spikes. NVIDIA's Multi-Instance GPU (MIG) feature, supported on T4 GPUs, allows partitioning to isolate workloads, ensuring consistent performance by dedicating GPU resources to the inference task. Option A (more threads) could increase contention, not reduce it. Option B (driver upgrade) mightimprove compatibility but doesn't address shared resource issues.
Option C (CPU deployment) reduces performance, not latency consistency. NVIDIA's documentation on MIG and inference optimization supports isolation as a best practice.
