A huge thanks to the LinuxAcademy community, and specifically to Thomas Haslett for his excellent AWS Essentials course and Christophe Limpalair for the Developer exam course. The material covered in both these courses should be more than sufficient to pass the exam. Having worked on AWS before, I found the questions to be on the easier side.
As others before me have stated here, there were a lot of questions on DynamoDB, S3, SQS, SNS, followed by EC2, ELB, Autoscaling and CloudFormation. If you have limited experience with AWS, I would recommend doing the live labs at least twice, one of those times without notes. Bottomline: There is no substitute for having practical, hands-on experience.
