NCA Containerization & NGC Catalog 5

Question 1

Which file must be configured on the host system to allow Docker to authenticate with the NGC container registry before pulling images?

Accepted Answer

~/.docker/config.json

Answer

Docker stores registry credentials in ~/.docker/config.json after running `docker login nvcr.io`, which is used for subsequent pull authentication.

Question 2

What is the purpose of the 'NVIDIA_DRIVER_CAPABILITIES' environment variable in NGC containers?

Accepted Answer

It controls which driver feature sets (compute, video, display, etc.) are exposed to the container

Answer

NVIDIA_DRIVER_CAPABILITIES selects which driver module capabilities (e.g., compute, compat32, graphics, utility, video, display) are mounted into the container.

Question 3

An NGC-optimized TensorRT container is best suited for which workload phase?

Accepted Answer

High-throughput, low-latency model inference and deployment

Answer

TensorRT containers are specifically optimized for inference, providing graph optimization, layer fusion, and precision calibration to maximize throughput and minimize latency.

Question 4

When a company needs to ensure that only their NGC API key is used to pull specific private containers, which NGC feature enforces this access control?

Accepted Answer

NGC Team Spaces with role-based access control

Answer

NGC Team Spaces provide organizational access management where admins can assign roles and restrict which users or API keys can access specific private registry content.

Question 5

What advantage does running NGC containers in rootless mode provide in a production security context?

Accepted Answer

It reduces the attack surface by ensuring container processes cannot gain host root privileges even if they escape the container

Answer

Rootless container mode runs the container runtime and processes as a non-root user, limiting privilege escalation risk if a container escape vulnerability is exploited.
