Exam NCA-AIIO Topic 2 Question 5 Discussion

Actual exam question for NVIDIA's NCA-AIIO exam
Question #: 5
Topic #: 2
Your AI infrastructure team is deploying a large NLP model on a Kubernetes cluster using NVIDIA GPUs.
The model inference requires low latency due to real-time user interaction. However, the team notices occasional latency spikes. What would be the most effective strategy to mitigate these latency spikes?

Suggested Answer: B Vote an answer

Latency spikes in real-time NLP inference often result from variable request rates. NVIDIA Triton Inference Server with Dynamic Batching groups incoming requests into batches dynamically, smoothing out processing and reducing spikes on NVIDIA GPUs in a Kubernetes cluster (e.g., DGX). This ensures low latency, critical for user interaction.
MIG (Option A) isolates workloads but doesn't address batching. More replicas (Option C) scale throughput, not latency consistency. Quantization (Option D) speeds inference but may not eliminate spikes. Triton's dynamic batching is NVIDIA's solution for this.
