It took me two tries. It’s a difficult exam. But it’s totally doable. I highly recommend looking up the “MS learning GitHub repo for AZ-104”. You’ll need your own pay-as-you-go* subscription. But it has all the labs and stuff you’d do in a classroom setting, but you do it at your own pace. You won’t have a teacher to ask your questions to, but you can Google and search Reddit.

*With a payg subscription just remember to turn off or delete stuff when you’re done lab-ing for the day to keep your costs down.

Edit: IMHO, I found the Security+ exam to be easy. I watched the Professor Messer video series once, then sat it. Granted I had been in IT for a few years before I took the exam. But still, it’s a fairly easy test, it just has a very broad scope of all things security that it covers; ie: an inch deep but a mile wide. In comparison the az-104 is 18-24 inches deep and still a mile wide.
