Question 520
At the Nortonwood regional data center, a training cluster has fast GPUs but all workers read a shared dataset from slow per-node USB storage. What should the team review routinely to prevent this problem?
Explanation
Correct Answer
After the immediate fix, the priority is to monitor storage hot spots and data locality as worker count grows. This reinforces the control against the original weakness: data access bandwidth and availability influence whether multiple GPUs can sustain useful compute. This directly addresses the reported issue at the Nortonwood regional data center.
Incorrect Answers
This routine applies to cluster management plane resilience, but it does not maintain the specific correction needed for the problem at the Nortonwood regional data center.
That practice helps control a different risk: congestion marking can provide earlier feedback than loss-only detection when configured end to end. The recurring control here should be to monitor storage hot spots and data locality as worker count grows. For the Nortonwood regional data center, the priority is to design appropriate shared or distributed storage and caching for concurrent accelerator data access.
The alternative suggests that the team review experiment frequency and price assumptions before long-term procurement; it would not directly prevent the observed issue from returning. For the Nortonwood regional data center, the priority is to design appropriate shared or distributed storage and caching for concurrent accelerator data access.
