I Just got recertified as my cisco network certification going to expires in 1 Oct 22. As I took a different paper but the cost of the exam fee is the name as last time taken in 1 Apr 2019 to passed it. So my cisco certification went up from Associate into Specialist. If I study and pass another exam in Core which exam fee is more expensive maybe got to study more harder I can level up to professional within 3 years from now before it expires to be invalid redo all over again.
