Why you might get asked this:
Evaluates your troubleshooting methodology, technical depth, and ability to work through complex issues systematically.
How to answer:
Use the STAR method. Detail the problem, your approach to diagnosis (gathering data, isolating variables), the steps you took to fix it, and the outcome.
Example answer:
"We experienced intermittent, difficult-to-diagnose network latency affecting multiple services. I systematically used packet sniffers and monitoring tools across various points in the network path, isolating the issue to a misconfigured routing table on a single node, which I then corrected, restoring stable connectivity."
