Yeah I only learned about that in the comments down below. I was just going off what they taught me when I took my network+ what 3 years ago?
Ethernet being reconditioned to Auto negotiate crossover connections was not covered or if it was it was a blurb and I forgot it in the meantime.
I have taken the A+ certification on two separate occasions and the first time I walked in with no training and aced it. The second time I walked in with no training and I struggled but I still passed.
The CompTIA certifications do get updated on a roughly 3-year cycle, but even so they're never going to cover everything and even if you can pass the test it doesn't actually mean that you are a competent IT person.
