Continuously retraining the model using a streaming data pipeline (C) ensures accuracy and relevance for real- time fraud detection. Financial fraud patterns evolve rapidly, requiring the model to adapt to new data incrementally. A streaming pipeline (e.g., using NVIDIA RAPIDS with Apache Kafka) processes incoming transactions in real time, updating the model via online learning or frequent retraining on GPU clusters. This maintains performance without downtime, critical for production environments.
* Static dataset retraining(A) lags behind emerging patterns, reducing relevance.
* Retrain only on accuracy drop(B) is reactive, risking missed fraud during degradation.
* Parallel rule-based systems(D) add redundancy but don't improve model adaptability.
NVIDIA's AI deployment strategies support continuous learning pipelines (C).

GPU underutilization with high CPU usage during training suggests a bottleneck in the data pipeline, where CPUs can't feed data to GPUs fast enough, starving them of work. Optimizing the data pipeline for better I/O throughput-using NVIDIA DALI for GPU-accelerated data loading or improving storage (e.g., NVMe SSDs)
-ensures data reaches GPUs efficiently, maximizing utilization. This is a common issue in NVIDIA DGX systems, where pipeline optimization is critical for large-scale workloads.
Increasing GPU memory (Option A) doesn't address data delivery. Reducing batch size (Option B) might lower GPU demand but reduces throughput, not solving the root cause. Adding GPUs (Option C) exacerbates underutilization without fixing the bottleneck. NVIDIA's training optimization guides prioritize pipeline efficiency.

Using Kubernetes Jobs with Directed Acyclic Graph (DAG) scheduling is the most efficient way to ensure job dependencies are respected in a multi-stage pipeline on a GPU cluster. Kubernetes Jobs allow you to define tasks that run to completion, and integrating a DAG workflow (e.g., via tools like Argo Workflows or Kubeflow Pipelines) enables you to specify dependencies explicitly. This ensures that dependent jobs only start after their prerequisites finish, automating the process and optimizing resource use on NVIDIA GPUs.
Increasing job priority (A) affects scheduling order but does not enforce dependencies. Deploying all jobs concurrently with pod anti-affinity (C) prevents resource contention but ignores execution order. Manual monitoring (D) is inefficient and error-prone. NVIDIA's "DeepOps" and "AI Infrastructure and Operations Fundamentals" recommend DAG-based scheduling for dependency management in Kubernetes GPU clusters.

NVIDIA's Data Center GPU Manager (DCGM) is specifically designed to monitor GPU health and performance in real-time, making it the most effective solution for proactively detecting and resolving issues like workload failures or slowdowns. DCGM provides detailed telemetry, including GPU utilization, memory usage, temperature, and error states, and supports health checks and alerts to notify administrators of anomalies (e.g., GPU faults, thermal throttling). Option A (weekly log reviews) is reactive and too slow for real-time issue detection in an AI data center. Option B (monitoring uptime and latency) provides indirect metrics but lacks GPU-specific insights critical for diagnosing failures. Option D (automatic restarts) addresses symptoms without identifying root causes, risking recurring issues. NVIDIA's official DCGM documentation emphasizes its role in cluster management, offering automated diagnostics and integration with tools like Prometheus for proactive monitoring, ensuring optimal GPU performance.

NVIDIA Jetson (D) is best suited for deploying AI workloads at the edge with minimal latency. The Jetson family (e.g., Jetson Nano, AGX Xavier) is designed for compact, power-efficient edge computing, delivering real-time AI inference for applications like IoT, robotics, and autonomous systems. It integrates GPU, CPU, and I/O in a single module, optimized for low-latency processing on-site.
* NVIDIA GRID(A) is for virtualized GPU sharing, not edge deployment.
* NVIDIA Tesla(B) is a data center GPU, too power-hungry for edge use.
* NVIDIA RTX(C) targets gaming/workstations, not edge-specific needs.
Jetson's edge focus is well-documented by NVIDIA (D).
