Show Suggested Answer Hide Answer
Suggested Answer: B

Before taking corrective action, you need to verify that the new firmware is indeed the root cause, such as by rolling back to the previous version in a controlled test or reproducing the failure in a lab, so you're sure your fix addresses the actual problem.

Wait, how do we know the bug is in the firmware? Sounds sketchy!

I’m a bit confused; I thought we should implement a solution right away if we suspect a bug. But maybe we need to confirm it first?

I think we had a practice question about troubleshooting that emphasized documenting lessons learned. So, option B might be the best choice here.

I’m not entirely sure, but I feel like establishing a plan of action first could help in organizing the next steps. Maybe option A?

I remember we discussed the importance of testing theories before jumping to conclusions. I think option B makes sense.
