Good day!
I had completed an Instructor Led Training for CCNA back in 2016 as part of my electives in my BSIT degree. We had 4 semesters of it. Now, I'm thinking of getting certified but I worry that what was taught to us is already obsolete. The curriculum we had mostly followed the CCNA v4 modules and I wanna know if I'm gonna need a refresher course before I take up the exam.
