Is LFS258 recognised ?

tangara

Hi,
I am new to Kubernetes as in I never had the chance to use it.
The reason I want to study is be'cos I still have no confidence in passing the damn difficult LeetCode exam employers are throwing at me and I am thinking of switching to do DevOp.
But, I am not sure if age will be a deterrant.
I'd like to know if LFS258 is recognised worldwide or in what countries ?
Basically I hope to have a skill that can do remote work and I am not sure if Kubernetes is a skill that allowed that ?
What is the average time line to complete a course like this and how long will I need to practise myself in order to pass the CKA exam ?
Hope to gather opinions before jumping into it.
Tks
