Answers:

When I started as a sysadmin, I realized Linux usually tells you exactly what is wrong if you look in the right places.

The three commands I relied on most were top (to see CPU and memory usage), df -h (to check disk space), and journalctl or system logs in /var/log (to understand what actually happened).

And when something breaks, the first thing I check is always the basics: disk space, running processes, and logs. Most problems quietly hide there.

Not clear Bhavi.  What is meant by <code>top</code>.  I thought that one just has to enter the command top, etc.
