Sample Question 3 — Cognition, Planning, and Memory

While deploying an AI agent using the NVIDIA Triton Inference Server, you notice that the agent's planning capabilities are not as efficient as expected. What could be a potential cause, and how would you address it?

  1. A. The model is not optimized for inference; use TensorRT-LLM for optimization. (Correct answer)
  2. B. The agent's memory module is overloaded; reduce the memory footprint.
