Is LFCS a practical or theoretical exam? On the Internet I see a lot of pages where they offer questions that will be on the exam, and on the linux foundation website is a pdf file for practical questions.
I am CCNA certified(done in 2018) n got a good package job with CCNA cert. But now going ahead with linux as well. So to cut short, you need both. For now go ahead with CCNA and learn a bit of linux(just learning, no cert). Once you grab a job, according to your project go ahead with Linux cert.
