Thank you KodeKloud. I needed the CKA for my next project. First we bought the certification and LF course. The LF course felt kinda slow and bad so I started googling around what should i use to pass the exam. Found KodeKloud and went all in. I Did the basic CKA course and after that one killer.sh. It was enough to pass the exam. Awesome job with the videos and labs.
once learnt cka, do one has to learn killer.sh, i don’t know killer.sh what is it?
Way to go! I just passed myself a few days ago. My employer bought me the LF course too, and it was… bad. 
killer.sh offers mock exams for certifications. Buying a CNCF certification exam also gives you two tries at a killer.sh mock exam.
