NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q139-Q144):

NEW QUESTION # 139
In your AI data center, you need to ensure continuous performance and reliability across all operations. Which two strategies are most critical for effective monitoring? (Select two)

A. Conducting weekly performance reviews without real-time monitoring
B. Deploying a comprehensive monitoring system that includes real-time metrics on CPU, GPU, and memory usage
C. Using manual logs to track system performance daily
D. Implementing predictive maintenance based on historical hardware performance data
E. Disabling non-essential monitoring to reduce system overhead

Answer: B,D

Explanation:
For continuous performance and reliability:
* Deploying a comprehensive monitoring system(D) with real-time metrics (e.g., CPU/GPU usage, memory, temperature via nvidia-smi) enables immediate detection of issues, ensuring optimal operation in an AI data center.
* Implementing predictive maintenance(E) uses historical data (e.g., failure patterns) to anticipate and prevent hardware issues, enhancing reliability proactively.
* Weekly reviews(A) lack real-time responsiveness, risking downtime.
* Manual logs(B) are slow and error-prone, unfit for continuous monitoring.
* Disabling monitoring(C) reduces overhead but blinds operations to issues.
NVIDIA's monitoring tools support D and E as best practices.

NEW QUESTION # 140
In your AI infrastructure, several GPUs have recently failed during intensive training sessions. To proactively prevent such failures, which GPU metric should you monitor most closely?

A. GPU Temperature
B. Frame Buffer Utilization
C. Power Consumption
D. GPU Driver Version

Answer: A

Explanation:
GPU Temperature (A) should be monitored most closely to prevent failures during intensive training.
Overheating is a primary cause of GPU hardware failure, especially under sustained high workloads like deep learning. Excessive temperatures can degrade components or trigger thermal shutdowns. NVIDIA's System Management Interface (nvidia-smi) tracks temperature, with thresholds (e.g., 85-90°C for many GPUs) indicating risk. Proactive cooling adjustments or workload throttling can prevent damage.
* Power Consumption(B) is related but less direct-high power can increase heat, but temperature is the failure trigger.
* Frame Buffer Utilization(C) reflects memory use, not physical failure risk.
* GPU Driver Version(D) affects functionality, not hardware health.
NVIDIA recommends temperature monitoring for reliability (A).

NEW QUESTION # 141
Which two software components are directly involved in the life cycle of AI development and deployment, particularly in model training and model serving? (Select two)

A. MLflow
B. Apache Spark
C. Kubeflow
D. Prometheus
E. Airflow

Answer: A,C

Explanation:
MLflow (B) and Kubeflow (E) are directly involved in the AI development and deployment life cycle, particularly for model training and serving. MLflow is an open-source platform for managing the ML lifecycle, including experiment tracking, model training, and deployment, often used with NVIDIA GPUs.
Kubeflow is a Kubernetes-native toolkit for orchestrating AI workflows, supporting training (e.g., via TFJob) and serving (e.g., with Triton), as noted in NVIDIA's "DeepOps" and "AI Infrastructure and Operations Fundamentals." Prometheus (A) is for monitoring, not AI lifecycle tasks. Airflow (C) manages workflows but isn't AI- specific. Apache Spark (D) processes data but isn't focused on model serving. NVIDIA's ecosystem integrates MLflow and Kubeflow for AI workflows.

NEW QUESTION # 142
In a distributed AI training environment, you notice that the GPU utilization drops significantly when the model reaches the backpropagation stage, leading to increased training time. What is the most effective way to address this issue?

A. Increase the learning rate to speed up the training process
B. Optimize the data loading pipeline to ensure continuous GPU data feeding during backpropagation
C. Implement mixed-precision training to reduce the computational load during backpropagation
D. Increase the number of layers in the model to create more work for the GPUs during backpropagation

Answer: C

Explanation:
Implementing mixed-precision training (D) is the most effective way to address low GPU utilization during backpropagation. Mixed precision uses FP16 alongside FP32, leveraging NVIDIA Tensor Cores to accelerate matrix operations in backpropagation, reducing compute time and memory usage. This keeps GPUs busier by increasing throughput, especially in distributed setups where synchronization waits can exacerbate idling.
* More layers(A) increases compute but may not target backpropagation efficiency and risks overfitting.
* Higher learning rate(B) affects convergence, not utilization directly.
* Data pipeline optimization(C) helps forward passes but not backpropagation compute bottlenecks.
NVIDIA's mixed precision is a proven solution for training efficiency (D).

NEW QUESTION # 143
Which of the following statements best explains why AI workloads are more effectively handled by distributed computing environments?

A. AI workloads require less memory than traditional workloads, which is best managed by distributed systems.
B. AI models are inherently simpler, making them well-suited to distributed environments.
C. Distributed systems reduce the need for specialized hardware like GPUs.
D. Distributed computing environments allow parallel processing of AI tasks, speeding up training and inference.

Answer: D

Explanation:
AI workloads, particularly deep learning tasks, involve massive datasets and complex computations (e.g., matrix multiplications) that benefit significantly from parallel processing. Distributed computing environments, such as multi-GPU or multi-node clusters, allow these tasks to be split across multiple compute resources, reducing training and inference times. NVIDIA's technologies, like NVIDIA Collective Communications Library (NCCL) and NVLink, enable high-speed communication between GPUs, facilitating efficient parallelization. For example, during training, data parallelism splits the dataset across GPUs, while model parallelism divides the model itself,both of which accelerate processing.
Option B is incorrect because AI models are not inherently simpler; they are often highly complex, requiring significant computational power. Option C is false as distributed systems typically rely on specialized hardware like NVIDIA GPUs to achieve high performance, not reduce their need. Option D is also incorrect- AI workloads often demand substantial memory (e.g., for large models like transformers), and distributed systems help manage this by pooling resources, not because the memory requirement is low. NVIDIA DGX systems and cloud offerings like DGX Cloud exemplify how distributed computing enhances AI workload efficiency.
