After initial setup and health checks, the DGX H100 system administrator wants to verify that...

The definitive "smoke test" for an NVIDIA-accelerated container environment is running nvidia-smi from within a container pulled from theNVIDIA GPU Cloud (NGC). Option D is the only 100% verified command because it includes all three necessary components:

--gpus all: This flag is required by the NVIDIA Container Toolkit to map the host's GPU device nodes and driver libraries into the container. Without it (as in Option C), the container will not "see" any GPUs.

nvcr.io/nvidia/cuda: Using an official CUDA base image from NGC ensures that the container has the necessary user-space libraries to communicate with the NVIDIA driver on the host.

nvidia-smi: This command specifically queries the driver and hardware. If it successfully prints the GPU table (showing the H100/A100 modules, their temperatures, and memory), it proves that the entire stack—from the physical hardware and kernel driver to the container runtime and toolkit—is functioning correctly.

Running ls -la (Option B) or systemctl (Option A) only tests that the container can run, but it does nothing to verify GPU accessibility or driver communication.
