Was much much harder than associate, for this exam you really need to be able to reason about security, architecture, scalability, availability and so on and be quick to answer because there's limited time.
I did find the course material useful, but it's lacking some information about BPG in VPC and on premise scenario's. Also the knowledge about EC2 instance sizes and specific disk / RAID surprised me a bit.
Happy overall I passed! Thanks LA for the material, very useful.
