this morning I have passed this cert. Thanks to linuxacademy for so good study material. the orion papers was very helpfull. I remember me imagining the orion papers in the scenario questions at the exam-
My tip for the exam is read at least twice aws guides and whitepapers, the faqs, and all the material that linux academy did for you.
Do the labs more than once,...and the do more labs on your own...use the sandbox aws lab to do whatever thing they let you.
Interiorize the aws console to feel comfortable and review all the main options of the services at web console level. Its very important how relation ELB with AG
Focus in how the services relation each other and how the services are integrated in aws, at AZ level, regions, VPC... more than remenber weird cli options or VPC limits.
EC2 for linux instances guide, ELB user guide and Auto Scaling guides are a must
Get a deep understanding of the services and their relations
I only missed more practice exams with scenario questions.
