PCB Bring-Up & Debug — question 9 of 10

Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.

A returned board occasionally resets under vibration during shipping or handling, but it works perfectly every time you have it sitting still on your bench. Simply tapping it a few times doesn't reproduce the fault. Walk me through your strategy for making this intermittent failure reliably reproducible enough to diagnose, and what root causes you'd suspect once you can trigger it on demand.

How sure are you?

Being confidently wrong costs more mastery than admitting a guess — that is deliberate, and it is how misconceptions get found.

Neither is graded, and nothing here is recorded.
