@Lakshmana said in Basic Linux Interview questions from ML:

@scottalanmiller whether every filesystem ext2,3,4 will be compatible for all hard disk?

That would be a very silly question. Way too basic for a Linux interview. That's a "what is a filesystem" kind of question, not for someone working in the field.

scottalanmiller

Asking the difference between ext2 and ext3, that's more of a Linux question. Or how to convert between them. But that's so old, seems unlikely.

@scottalanmiller said in Basic Linux Interview questions from ML:

Putty is just a Windows tool for connecting to SSH. Linux will have questions about working from the command line, but I would not expect questions about a purely Windows connection tool.

I've used Putty for Telnet. But I use it even more for Serial connections for initial setups of switches.

But yeah, main usage is SSH in Windows.

Make sure you understand Linux memory and processes. How to start and stop services. Make sure that you know what distro(s) they are going to be interviewing you on as each is a unique OS and there is no generic "Linux" to interview you about.

Common services like NFS, Apache or such are often asked about.

Troubleshooting common problems, like tracking down abusers on full disks, run away processes and memory leaks.

Make sure that you know what a zombie process is. Seems to always get asked.

Make sure that you know your Linux Bonding Modes.

@Lakshmana ,

I think you should start your training from the beginning. You have alot of knowledge of different commands, file systems, scenarios, etc, but you always seem to struggle with the basics.

Linux or anything else in IT is alot like math in the way that you must understand counting, and addition and subtraction before you can learn algebra and calculus.

Check out udemy.com. They have some great training material at a very fair price.
