A telecommunications company is rolling out an AI-based system to optimize network traffic and improve customer experience across multiple regions. The system must process real-time data from millions of devices, predict network congestion, and dynamically adjust resource allocation. The infrastructure needs to ensure low latency, high availability, and the ability to scale as the network expands.
Which NVIDIA technologies would best support the deployment of this AI-based network optimization system?
- A . Deploy the system on NVIDIA Tesla P100 GPUs with TensorFlow Serving for inference.
- B . Implement the system using NVIDIA Jetson Xavier NX for edge computing at regional network hubs.
- C . Use NVIDIA BlueField-2 DPUs for offloading networking tasks and NVIDIA DOCA SDK for orchestration.
- D . Utilize NVIDIA DGX-1 with CUDA for training AI models and deploy them on CPU-based servers.
Your AI model training process suddenly slows down, and upon inspection, you notice that some of the GPUs in your multi-GPU setup are operating at full capacity while others are barely being used.
