NEW QUESTION # 67
When monitoring a GPU-based workload, what is GPU utilization?
Answer: D
Explanation:
GPU utilization is defined as the percentage of time the GPU's compute engines are actively processing data, reflecting its workload intensity over a period (e.g., via nvidia-smi). It's distinct from memory usage (a separate metric), core counts, or maximum runtime, providing a direct measure of compute activity.
NEW QUESTION # 68
What is a significant benefit of using containers in an AI development environment?
Answer: C
Explanation:
Containers (e.g., Docker) encapsulate AI applications with their dependencies, ensuring consistent execution across diverse environments-from development laptops to production clusters-without manual reconfiguration. They don't inherently improve model accuracy, generate datasets, or boost GPU speed, focusing instead on portability and reproducibility.(Note: The document incorrectly lists A; B is correct per NVIDIA standards.) (Reference: NVIDIA AI Infrastructure and Operations Study Guide, Section on Containers in AI Development)
NEW QUESTION # 69
In a large enterprise cluster, frequent out-of-memory errors occur mid-experiment. What operational feature resolves this?
Answer: B
Explanation:
The correct answer is B because out-of-memory issues in shared AI clusters are typically addressed through workload resource management, reservations, and monitoring. NVIDIA Run:ai documentation states that workload management includes "Workload scheduling" to "prioritize and allocate GPUs based on workload needs" and "Monitoring and insights" to "track real-time and historical data on GPU usage to help track resource consumption and optimize costs." It also says NVIDIA Run:ai supports "Fractional GPU usage" so users can "request and utilize only a fraction of a GPU's memory, ensuring efficient resource allocation and leaving room for other workloads." This directly supports option B: resource reservation and usage monitoring in the workload manager.
Containers do not "boost" physical GPU memory, and simply increasing node count automatically does not correct the root cause if jobs are not requesting, reserving, or being monitored for the correct memory usage.

NEW QUESTION # 70
An autonomous vehicle company is developing a self-driving car that must detect and classify objects such as pedestrians, other vehicles, and traffic signs in real-time. The system needs to make split-second decisions based on complex visual data. Which approach should the company prioritize to effectively address this challenge?
Answer: C
Explanation:
Real-time object detection and classification in autonomous vehicles require processing complex visual data (e.g., camera feeds) with high accuracy and minimal latency. Deep learning models with convolutional neural networks (CNNs) are the industry standard for this task, excelling at feature extraction and pattern recognition in images. NVIDIA's automotive solutions, like DRIVE AGX and TensorRT, optimize CNNs for real-time inference on GPUs, enabling split-second decisions critical for safety. For example, CNN-based models like YOLO or SSD, accelerated by NVIDIA GPUs, can detect and classify pedestrians, vehicles, and signs efficiently.
Unsupervised learning (Option A) is unsuitable for precise classification without labeled training data, which is essential for this use case. Linear regression (Option B) is too simplistic for multidimensional visual data, lacking the ability to handle complex patterns. Rule-based systems (Option C) are rigid and struggle with the variability of real-world scenarios, unlike adaptable CNNs. NVIDIA's focus on deep learning for autonomous driving underscores Option D as the prioritized approach.
NEW QUESTION # 71
Which NVIDIA platform is used to build and deploy commercial-grade, AI-powered robots?
Answer: A
Explanation:
NVIDIA Isaac is the platform designed for developing and deploying AI-powered robots, providing simulation, AI models, and SDKs tailored for robotics applications.
