It's so crazy to see every other comment on this subreddit basically just saying "Oh, get the CompTIA trifecta and you're set!" No, just no.

In my opinion, CompTIA is literal garbage. They are a shady company (lobbying against the right to repair) with useless certs that don't teach you anything. My company 6 years ago offered to let me take it for free, and I was appalled at the amount of incorrect information presented in the training.

If you need to teach yourself the fundamentals, just use the internet. It's the largest conglomerate of free information on the planet. I'm not even really on board with certs in general, as I feel they don't do much for you unless a specific job requires it. However, I don't have a problem with the actual respected ones. (Red Hat, Cisco, VMware, etc...)
