NVIDIA Exam NCA-AIIO Topic 2 Question 3 Discussion

Variability in the GPU load due to other tenants on the same physical hardware is the most likely cause of inconsistent inference times in a cloud-based NVIDIA GPU deployment. In multi-tenant cloud environments (e.g., AWS, Azure with NVIDIA GPUs), instances share physical hardware, and contention for GPU resources can lead to performance variability, as noted in NVIDIA's 'AI Infrastructure for Enterprise' and cloud provider documentation. This affects inference latencydespite identical instance types.

CUDA version differences (A) are unlikely with consistent instance types. Unsuitable model architecture (B) would cause consistent, not variable, slowdowns. Network latency (C) impacts data transfer, not inference on the same instance. NVIDIA's cloud deployment guidelines point to multi-tenancy as a common issue.
