Hi guys, I'm so excited that I just passed the LFCS after a several postpone times. In the beginning, I decided to choose RHCSA because it is more popular than LFCS but recognized the RedHat lab is not located in my country (Viet Nam), and it is also more expensive \~ $150 when compare to LFCS but they are pretty similar 70-80% content.

My backgrounds:

• I have been working as Java/golang developers in only one outsource company for 6 years with salary \~ $1500/month (no idea is it high or low salary in VN)
• My main responsibility in many projects are coding backend microservices, deploying, and monitoring all Linux & Windows servers and AWS resources. Sometimes I applied the CI/CD tools such as Jenkins, K8s, Docker,... to the projects as requests from customers.
• Besides this LFCS cert, I got a some certs as AWS SAA, Azure Fundamentals, CKA, and have some Project management certs PSM, PSPO, CAPM

Learning Resources:

• I tried some RHCSA mock exams from Udemy before deciding to take LFCS, so I have some fundamental essential commands in Linux already.
• For the LFCS course, I only chose the course from KodeKloud https://www.udemy.com/course/linux-foundation-certified-systems-administrator-lfcs . As far as I remember, the content in this course has been modified some times in November last year and April this year after the LF change LFCS's content and certificate's policy from 3yrs to 2yrs :((. Those changes make me so exhausted because the course was not stable to learn. But I think for now it would be better than.
• Killer.sh: this simulator is very useful after I finished the KodeKloud course above. I don't remember how many times I did it in 1 session (36 hours), but I spent all my weekend days in this, I try to finished it and refresh the session around 2 hours and do it from 08:00AM to until 23:00PM when my eyes couldn't open anymore.

My learn:

• After finishing my tasks in the company, I was still sitting down the chair and spent time from 18:00 to 21:00 to learn LFCS and practice the mock exam. Wrote down all mistakes I got in a note, then go home and practice again.
• Everytime I got mistakes in the mock exams and don't remember command, I always write down a whiteboard in my room. This way help me to remember when I walk into my room
• I re-do all exams around 2 weeks in September until get boring, then I decided to whether re-do them or take the real exam. Finally I chose the 2nd option :))

Exam day:

• In the exam day, I really don't take any mock exams, just only looked the whiteboard and try to remember all mistake I've gotten, search google to get more inform and get more confident.
• I have no empty room in my house, so I request the Administrator in the company to use a meeting room after all employees leave their working day at 18:30 to 20:30.
• The PSI proctor was a bit strict, they asked me to check all room and devices 2-3 times before approving the exam.
• The real test was not hard as much as I though. If you prepared all mock exams I mentioned above enough, I think you can finish it within 1 hour.
• While taking, there were 2 questions I didn't remember cmd and parameters to execute, I spent 1 remaining hour for only 2 these questions and finally I gave up after messing them up.

After 24 hours after taking. The LF email says that I passed. Finally I can take a rest some days before getting a new road.

What's next?

• I'm intending to learn and get PMP cert. I lean and do everything for my passion, no one ask me to learn more and try to get more salary. Currently a lot of IT guys/developers in Viet Nam are getting layoff, I don't know when is it my turn :)) I still keep learn, it like a way to protect myself with this difficult time.
• I also intent to learn the IELTS to improve my english speaking skill. Although I'm working with some clients from oversea like Singapore, Australia,... actually my English speaking is really not good. I don't know how to improve it currently except studying the IELTS.
• I will try to get a remote job to monitor/deploy servers to get a food on the table for my family if possible. IMO, if I have a lot of certs but I cannot get money from them, they are still zero. Currently I still have no idea how to get a remote job.

That's it. I hope you guys have a plan to get LFCS or RHCSA can get more info about it. English is not my native language, and I haven't used Chatgpt to correct them, so maybe have some mistakes or misunderstanding to read. Please feel free to leave a comment, I will try all my best to answer them. But please don't ask about the exam content, it would not only violate the policy but also make your emotion down while learning Linux and acing the exam :)) Good luck
