NCP-AIO Installation and Deployment Practice Question
During an air-gapped installation of the NVIDIA GPU Operator, the administrator must make all required images available to the cluster. Which component is responsible for pulling the Operator's operand images from the private registry?
⚠ Common exam trap
The trap here is assuming a kubelet mirror or pull secret is sufficient to redirect operand images, when the ClusterPolicy must explicitly reference the private registry.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The GPU Operator's ClusterPolicy must reference the private registry so operand pods use images from that registry.
Air-gapped deployments require the ClusterPolicy to specify the private registry and repository paths for each operand image. This directs the Operator to deploy pods that pull driver, toolkit, device plugin, and monitoring images from the internal registry. Kubelet mirrors, toolkit configuration, and image pull secrets address adjacent concerns but do not select the operand image sources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The NVIDIA Container Toolkit must be pointed at the private registry through its config.toml file.
Why it's wrong here
The container toolkit configures runtime hooks for GPU access, not image pull sources for Operator operands. It has no role in selecting which registry the driver, device plugin, or DCGM exporter images come from. This option confuses runtime configuration with image sourcing and does not solve the air-gapped pull requirement.
- ✗
The Operator's Helm chart values must include an imagePullSecret for the private registry on every namespace.
Why it's wrong here
An image pull secret provides authentication but does not redirect image references to a private registry. The ClusterPolicy must still specify the private repository paths. While pull secrets may be needed for authenticated registries, they are not the component that determines which registry the operand images are pulled from.
- ✗
The kubelet on each node must be configured with a mirror registry that rewrites all container image pulls.
Why it's wrong here
A kubelet mirror registry can rewrite pulls for some runtimes, but it is not the mechanism the GPU Operator uses to select operand images. The Operator explicitly references image repositories in the ClusterPolicy, so relying on a mirror alone would not guarantee the correct operand images and versions are used in an air-gapped deployment.
- ✓
The GPU Operator's ClusterPolicy must reference the private registry so operand pods use images from that registry.
Why this is correct
In an air-gapped environment, the ClusterPolicy is configured with the private registry path and image repository settings for each operand, such as driver, toolkit, device plugin, and DCGM exporter. This ensures the Operator deploys pods that pull from the internal registry rather than the public NVIDIA registry, which is unreachable.
