Common Interview Questions for System Administrator

1. Can you explain how you would troubleshoot a network outage?
In this scenario, explain your step-by-step approach to identifying the cause of the issue. Start with checking physical connections, ensuring the router and switches are operational, and then move to software-level troubleshooting like DNS, IP configurations, and network settings.
