Sample answer
“In my previous role at Telecom Italia, I encountered a situation where a remote office was experiencing intermittent connectivity issues. I used ping tests and traceroute to identify the point of failure in the WAN. After collaborating with the ISP to check for outages, I discovered a faulty router at the site. I replaced the router, which restored connectivity, and I also implemented a monitoring solution to catch such issues proactively in the future. This experience taught me the importance of thorough diagnostics and effective communication.”
