NCP-AIO Installation and Deployment Practice Question
Which action must be performed after updating the NVIDIA driver on a Linux host to ensure that all active GPU containers recognize the new driver version?
⚠ Common exam trap
Candidates assume updating the host driver is instantly inherited by running containers, forgetting that active containers retain bindings to old libraries until restarted.
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
✓
Restart the containerized applications.
Containers utilize the host-level NVIDIA drivers injected via the container toolkit. When the host driver is updated, active containers will still be referencing the old driver libraries in their environment until they are restarted. Restarting the containers is the mandatory step to force them to bind against the newly installed libraries, ensuring compatibility and preventing runtime errors associated with outdated driver interfaces.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rebuild all container images with the latest CUDA toolkit.
Why it's wrong here
Rebuilding images is unnecessary. The container toolkit dynamically mounts the driver libraries from the host into the container at runtime. The container image itself usually contains only the CUDA user-mode libraries, which are generally forward-compatible with the updated host kernel-mode driver.
- ✓
Restart the containerized applications.
Why this is correct
Active containers hold references to the old driver files that were mapped during their initialization. To ensure that the containers are using the updated driver libraries from the host, the processes must be terminated and relaunched so the container runtime can remount the latest versions.
- ✗
Upgrade the Docker daemon version.
Why it's wrong here
The Docker daemon does not need an upgrade to handle driver updates. The container runtime interface remains consistent, and the driver update is a separate kernel-level operation that does not require changing the orchestration engine to be effectively utilized by the running containers.
- ✗
Re-run the nvidia-container-toolkit installation script.
Why it's wrong here
The toolkit installation script is only needed for the initial setup. Subsequent driver updates are managed by the operating system package manager. Once the driver is updated on the host, the existing toolkit installation will correctly pick up and mount the new driver libraries.
