A water-utility digital-twin rack finishes OS install on GPU nodes. What should operators validate before installing NVIDIA drivers?
Select an answer to reveal the explanation.
Short Explanation
After the OS lands, check hostname and DNS before you pile on GPU drivers—like confirming a pump station’s radio call sign before loading new firmware tools. Nameless nodes make later ops painful.
Full Explanation
After OS install on the water-utility digital-twin rack, operators should validate post-OS hostname and DNS identity on each GPU node before installing NVIDIA drivers. Stable network identity underpins BCM management, package repositories, certificates, monitoring, and later job scheduling. Confirming hostname and DNS early prevents driver and toolkit work from landing on nodes that cannot be addressed or audited correctly.
Installing drivers before any hostname exists skips identity establishment and makes subsequent management and troubleshooting brittle. Permanently disabling DNS so nodes never resolve breaks repo access, service discovery, and municipal monitoring patterns. Using only BMC MAC addresses as human-facing hostnames forever conflates OOB hardware addressing with OS-level identity operators and schedulers actually use.
Exam caveat: post-OS validation prioritizes hostname/DNS (node identity) before GPU driver install—not driver-first nameless hosts or DNS sabotage.
Operational check: for each node, verify hostname, forward/reverse DNS (or approved internal resolution), management reachability, then proceed to NVIDIA driver installation and record identity in inventory.
