You want to test a network design with no hardware. What fits?
Why B is the answer
NVIDIA DSX Air
NVIDIA DSX Air simulates network environments, so a design can be tested with no hardware.
In detail
- NVIDIA names DSX Air for simulating network environments.
- Simulation finds mistakes early.
Use case
An illustrative scenario, not a real incident.
A team tests a design in DSX Air before it buys any hardware.

Key point: DSX Air simulates networks.
Why the other options are wrong
- A. A cable tester on each link
- That needs real hardware.
- C. ib_write_bw
- That needs real hardware.
- D. nvidia-smi
- That is a GPU tool.
