NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q27-Q32):

NEW QUESTION # 27
Your team is running an AI inference workload on a Kubernetes cluster with multiple NVIDIA GPUs. You observe that some nodes with GPUs are underutilized, while others are overloaded, leading to inconsistent inference performance across the cluster. Which strategy would most effectively balance the GPU workload across the Kubernetes cluster?

A. Using CPU-based autoscaling to balance the workload
B. Implementing GPU resource quotas to limit GPU usage per pod
C. Reducing the number of GPU nodes in the cluster
D. Deploying a GPU-aware scheduler in Kubernetes

Answer: D

Explanation:
Deploying a GPU-aware scheduler in Kubernetes (A) is the most effective strategy to balance GPU workloads across a cluster. Kubernetes by default does not natively understand GPU resources beyond basic resource requests and limits. A GPU-aware scheduler, such as the NVIDIA GPU Operator with Kubernetes, enhances the orchestration by intelligently distributing workloads basedon GPU availability, utilization, and specific requirements of the inference tasks. This ensures that underutilized nodes are assigned work while preventing overloading of others, leading to consistent performance.
* Implementing GPU resource quotas(B) can limit GPU usage per pod, but it doesn't dynamically balance workloads across nodes-it only caps resource consumption, potentially leaving some GPUs idle if quotas are too restrictive.
* Using CPU-based autoscaling(C) focuses on CPU metrics and ignores GPU-specific utilization, making it ineffective for GPU workload balancing in this scenario.
* Reducing the number of GPU nodes(D) might exacerbate the issue by reducing overall capacity, not addressing the imbalance.
The NVIDIA GPU Operator integrates with Kubernetes to provide GPU-aware scheduling, monitoring, and management, making (A) the optimal solution.

NEW QUESTION # 28
You are managing an AI data center where energy consumption has become a critical concern due to rising costs and sustainability goals. The data center supports various AI workloads, including model training, inference, and data preprocessing. Which strategy would most effectively reduce energy consumption without significantly impacting performance?

A. Consolidate all AI workloads onto a single GPU to reduce overall power usage.
B. Reduce the clock speed of all GPUs to lower power consumption.
C. Schedule all AI workloads during nighttime to take advantage of lower electricity rates.
D. Implement dynamic voltage and frequency scaling (DVFS) to adjust GPU power usage based on workload demands.

Answer: D

Explanation:
Dynamic Voltage and Frequency Scaling (DVFS) allows GPUs to adjust their power usage dynamically based on workload intensity, reducing energy consumption during low-demand periods while maintaining performance when needed. NVIDIA GPUs, such as those in DGX systems, support DVFS through tools like NVIDIA Management Library (NVML) and nvidia-smi, enabling fine-tuned power management. This approach balances efficiency and performance, critical for diverse AI workloads like training (high compute) and inference (variable demand), aligning with NVIDIA's energy-efficient computing initiatives.
Consolidating workloads onto a single GPU (Option A) risks overloading it, degrading performance and negating energy savings due to inefficiency. Scheduling workloads at night (Option C) addresses cost but not total consumption or sustainability, and it may delay time-sensitive tasks. Reducing clock speed universally (Option D) lowers power use but sacrifices performance across all workloads, which is impractical for an AI data center. DVFS is the most effective NVIDIA-supported strategy here.

NEW QUESTION # 29
Your company is planning to deploy a range of AI workloads, including training a large convolutional neural network (CNN) for image classification, running real-time video analytics, and performing batch processing of sensor data. What type of infrastructure should be prioritized to support these diverse AI workloads effectively?

A. On-premise servers with large storage capacity
B. CPU-only servers with high memory capacity
C. A cloud-based infrastructure with serverless computing options
D. A hybrid cloud infrastructure combining on-premise servers and cloud resources

Answer: D

Explanation:
Diverse AI workloads-training CNNs (compute-heavy), real-time video analytics (latency-sensitive), and batch sensor processing (data-intensive)-require flexible, scalable infrastructure. A hybrid cloud infrastructure, combining on-premise NVIDIA GPU servers (e.g., DGX) with cloud resources (e.g., DGX Cloud), provides the best of both: on-premise control for sensitive data or latency-critical tasks and cloud scalability for burst compute or storage needs. NVIDIA's hybrid solutions support this versatility across workload types.
On-premise alone (Option A) lacks scalability. CPU-only servers (Option B) can't handle GPU-accelerated AI efficiently. Serverless cloud (Option C) suits lightweight tasks, not heavy AI workloads. Hybrid cloud is NVIDIA's strategic fit for diverse AI.

NEW QUESTION # 30
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. Manually reassign workloads based on current utilization
B. Increase cooling capacity in the data center
C. Implement NVIDIA GPU Operator with Kubernetes for automatic resource scheduling
D. Use horizontal scaling to add more servers

Answer: C

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 # 31
You are working with a large dataset containing millions of records related to customer behavior. Your goal is to identify key trends and patterns that could improve your company's product recommendations. You have access to a high-performance AI infrastructure with NVIDIA GPUs, and you want to leverage this for efficient data mining. Which technique would most effectively utilize the GPUs to extract actionable insights from the dataset?

A. Visualizing the data using a standard spreadsheet application
B. Employing a simple decision tree model to classify customer data
C. Using traditional SQL queries to filter and sort the data
D. Implementing deep learning models for clustering customers into segments

Answer: D

Explanation:
Implementing deep learning models for clustering customers into segments is the most effective technique to utilize NVIDIA GPUs for extracting actionable insights from a large customer behavior dataset. Deep learning models (e.g., autoencoders, neural networks) excel at unsupervised clustering of complex, high- dimensional data, identifying subtle trends and patterns for recommendations. NVIDIA GPUs accelerate these models via libraries like cuDNN and frameworks like PyTorch, as noted in NVIDIA's "Deep Learning Institute (DLI)" and "AI Infrastructure for Enterprise" resources, making them ideal for GPU-powered data mining.
Spreadsheets (A) and SQL queries (B) lack scalability and GPU utilization. Decision trees (D) are simpler but less effective for large-scale pattern discovery. Deep learning on GPUs is NVIDIA's recommended approach.
