What does Spectrum-X add for AI workloads on Ethernet?
Why A is the answer
Adaptive routing and congestion control tuned for AI traffic
AI training produces large flows that hash badly. Adaptive routing spreads them across paths.
In detail
- Spectrum-X adds adaptive routing and congestion control for AI.
- AI traffic has large flows that hash badly.
Use case
An illustrative scenario, not a real incident.
Large training flows hash onto the same paths. Adaptive routing in Spectrum-X spreads them across paths.

Why the other options are wrong
- B. Layer 7 load balancing for inference APIs
- That is application load balancing.
- C. Static routing with a fixed path for each flow
- A fixed path cannot adapt.
- D. Traditional ECMP hashing with larger buffers
- That is traditional hashing.
