Are there any good resources for diving into the subject material? I figure I'd just go to the subreddit r/networking or whatever, reddit has everything usually.
They probably have good sources on the subreddit. I used Cisco's self study store (learningnetworkstore.cisco.com) where they have programs to guide you through an online curriculum based on the cert you want. It worked well enough to where I passed ccent on my first try. I needed some structure so I shelled out the money for it. ($750) There are most likely other cheaper alternatives but might need more self discipline.
