Question 170
An infrastructure administrator receives the following incident: A storage array is reachable from AI nodes, but a shared mount used for checkpoints lacks the expected write permissions for the training service identity. Which measured result most directly proves that this specific problem is resolved?
Explanation
Correct Answer
This is the measurable acceptance result for the described case: A controlled checkpoint writes and restores successfully using the production service identity without granting unintended cross-tenant access. It validates the corrective operation (Configure third-party storage export and access policy for the approved training user, then verify read/write and ownership semantics.) rather than a related but different system check.
Incorrect Answers
This observation would help verify a different incident: A cluster is commissioned with redundant front-end networks but a single storage path, and a switch maintenance outage disconnects all training checkpoints. It does not directly establish the required result for the current case: A controlled checkpoint writes and restores successfully using the production service identity without granting unintended cross-tenant access.
This observation would help verify a different incident: AI researchers create training directories on a shared NAS but capacity is not monitored; a large dataset import consumes the space reserved for critical model checkpoints. It does not directly establish the required result for the current case: A controlled checkpoint writes and restores successfully using the production service identity without granting unintended cross-tenant access.
This observation would help verify a different incident: An AI factory receives firmware packages from an emailed archive without checking their source or signature, exposing management processors to untrusted code. It does not directly establish the required result for the current case: A controlled checkpoint writes and restores successfully using the production service identity without granting unintended cross-tenant access.
