If you want to demonstrate your system administration skills to your current/future employer then I would highly recommend to do LFCS certification. The exam consists of performance-based items that simulate on-the-job tasks and scenarios faced by sysadmins in the real world. Candidates can select either Ubuntu 18 or CentOS 7.
On Oct21 I have decided to take a jump in my DevOps journey and enrolled myself for cloud engineer bootcamp provided by Linux Foundation.
In that bootcamp there are 5 courses and 2 certifications. LFCS was one of that. If you look into there timeline, then after completing LFS201 and LFS211 you are ready to give exams. It took me 3 months i.e. till the beginning of Jan to complete both the course. ( It took me long as I have my fulltime job also as a DevOps Engineer).
After that I started looking for some blogs and other people's preparation guide on how to clear LFCS certification.
Then I did a lot of practices on different problems of various topics.
Here is the checklist
- Essential Commands 25%
- Operation of Running Systems 20%
- User and Group Management 10%
- Networking 12%
- Service Configuration 20%
- Storage Management 13%
Also you can get full Preparation guide from Linux Foundation
After having good practice I decided to give my exam on 6th Feb 2021(Sunday early Morning IST).
And here is the result (😃)
man -k <keyword>is your go to guy to get any clue about any command/topic.
- Don't memorise the command instead practice and understand the concept.
- Keep practice on your virtual machine and not on any bare metal box. ( I have crashed my VM many times due to wrong configurations in partition 😁 )
- When you practice don't do google try to always look in man. Think like what if I forgot what needs to be write in config or what will be command then where I have to look.( Most probably there will be default conf under etc or you can look man).
- Remember questions are not that much tough in the exam, It is the time where people usually fail. I myself not able to attempt 2 questions(which is of marks). So don't stick on a single question for more than 5-7 mins.
Lastly solve as much problem as you can, complete the Practice Questions. All the best.
