Solutions Architect-Associate

I passed my AWS Certified Solutions Architect exam, I got certified !

I did have over 1 year expierence before taking the exam.
There were lots of questions about EBS,AutoScale,ElasticIP,VPC,etc…

I remember little about specific questions, I only had one major doubt on one.
It was about placement groups

I recommend reading the white papers!

I did almost all of the https://cloudacademy.com/ Tests, the questions are not like the real ones but the knowledge will help!
