Just passed. Spent probably... a month or 2 studying on/off. I have 1-2 months experience working in a production AWS environment, but only with read access.
The LinuxAcademy videos were my main study resource. They're pretty good, but you should supplement with other material. The few Amazon FAQs I read were pretty good, but honestly you'll want to invest in as much hands on time as possible.
There was a lot of material I was tested on that I didn't realize I needed to know so I just guessed. That's probably my fault though, as I never looked for a rubric and just relied on what the LinuxAcademy videos were covering.
Also used the udemy practice questions (They're like $10). They were pretty good for refreshing my memory on certain things, but they're a bit too easy. The actual exam is much more difficult.
Autoscaling, IAM, load balancers, and Route53 all murdered me lol. I just didn't study them as deeply as was necessary for the exam.
Overall Score: 64%
Topic Level Scoring:
1.0 Designing highly available, cost efficient, fault tolerant, scalable systems: 62%
2.0 Implementation/Deployment: 60%
3.0 Security: 55%
4.0 Troubleshooting: 100%
Anyways, a pass is a pass, even if it's a pretty bad score haha. I'm happy I got it out of the way. I think my 100% in troubleshooting is because I've had to do a decent amount of it in my actual job in the last few months. Hands on experience is crucial for this exam IMO.
I'm debating on getting the developer cert as well, but I'm going to refocus back onto some security stuff first. Plus I just signed up for a Master's program, so that will probably keep me busy for a bit.
Let me know if you have any questions, I'd be happy to answer what I can.
