Which GPU Operator part reports GPUs to the Kubernetes scheduler?
Why D is the answer
The device plugin
It advertises nvidia.com/gpu resources.
In detail
- The device plugin advertises nvidia.com/gpu resources.
- Without it, GPUs stay invisible to Kubernetes.
Use case
An illustrative scenario, not a real incident.
The device plugin advertises nvidia.com/gpu, so the scheduler can place pods.

Key point: The device plugin reports GPUs.
Why the other options are wrong
- A. The DCGM exporter
- That publishes metrics.
- B. The driver container
- That installs the driver.
- C. The MIG manager
- That handles MIG.
