Free NVIDIA NCA-AIIO Actual Exam Questions - Question 5 Discussion
multiple nodes. You need to ensure that the model training is scalable, with efficient data transfer
between the nodes to minimize latency. Which of the following networking technologies is most
suitable for this scenario?
C/D? While InfiniBand is great for low latency, 1 Gbps Ethernet might bottleneck heavy GPU data. Fiber Channel seems off since it's storage-focused, and Wi-Fi 6 just won’t cut it for this scale.
Guessing C, InfiniBand is built for high-performance GPU clusters, unlike others.
C imo, Wi-Fi and Ethernet just can’t match the speed and latency needed here.
Fiber Channel is mainly for storage, so it lacks the GPU-focused speed needed here.
Maybe C, InfiniBand’s low latency is key for syncing multiple GPU nodes fast.
It’s C for sure. The key is low latency and high bandwidth for GPU communication, and InfiniBand nails both better than anything else here. Fiber Channel just doesn’t handle this kind of data transfer well.
I’m thinking it’s not A or D since Wi-Fi and 1 Gbps Ethernet just won’t cut it for heavy GPU-to-GPU communication. Fiber Channel is mostly for storage networks, so B seems off for training workloads. That leaves C, InfiniBand, which is known for ultra-low latency and high throughput, perfect for multi-node GPU setups. But just checking—do we know if they need something that’s also cost-effective, or purely performance matters here?
It’s C because InfiniBand offers much higher bandwidth and lower latency compared to standard Ethernet or Wi-Fi, which is crucial for syncing GPU workloads across nodes efficiently. Fiber Channel just doesn’t fit this use case.
It’s C—Fiber Channel is mostly for storage, so not ideal here.
C imo. InfiniBand’s low latency and high bandwidth are specifically designed for HPC and GPU cluster communication, which makes it way better than Ethernet or Wi-Fi for this kind of heavy data transfer.
C looks best here. InfiniBand is known for low latency and high throughput, perfect for multi-node GPU training setups. Wi-Fi and 1 Gbps Ethernet are too slow, and Fiber Channel is more for storage networks.
