問題文
A design separates the accelerator to accelerator fabric from the network that carries user requests, shared storage traffic and management access. What is the main purpose of that separation?
選択肢
- To let the accelerators reach the internet directly without passing through the management network, which is the only way a training job can download its data set from an external source during the run.
- To reduce the number of switches required, as a dedicated fabric can be built with fewer devices than a single shared network of the same capacity, and the equipment budget falls accordingly.
- To remove the need for quality of service, given that a dedicated fabric guarantees that no class of traffic can ever be delayed inside it.
- To keep the collective traffic, which is bursty and fills the links, from competing with traffic whose response time or availability matters for other reasons.
