Question 70
At the Westhaven distributed training group, production inference nodes pull different weight versions and return inconsistent results for the same approved prompt. Which statement best identifies the control gap?
Explanation
Correct Answer
The situation indicates that version drift across replicas can invalidate validation and create unpredictable prediction differences. The recommended response is to promote immutable approved model artifacts to serving replicas with controlled version references, with a follow-up check that all healthy serving replicas report the approved model version and pass the same reference test. This directly addresses the reported issue at the Westhaven distributed training group.
Incorrect Answers
A lengthy training job is vulnerable to interruption without usable restart state. This can occur in other projects, but it is not the primary explanation at the Westhaven distributed training group.
This explanation belongs to accelerator parallelism impact. The immediate weakness in the question is that version drift across replicas can invalidate validation and create unpredictable prediction differences. For the Westhaven distributed training group, the priority is to promote immutable approved model artifacts to serving replicas with controlled version references.
Although an accelerator board or platform requires surrounding server power cooling storage networking and software design, the situation does not describe that specific cause; it instead indicates that version drift across replicas can invalidate validation and create unpredictable prediction differences. For the Westhaven distributed training group, the priority is to promote immutable approved model artifacts to serving replicas with controlled version references.
