Today I passed the AWS Solutions Architect Associate exam. LA was my only souce of study and I managed to prepare for the test in a month. I finished the course material in two weeks and spent around two weeks on any practice test I found online.
The test was not easy at all and it took me 110 minutes to complete. My recommendation: think about any service you learn from five pillars of well-architected framework perspective. No matter it's covered in videos or not; do your own research if not covered. Next step would be a combination of services and five pillars; for example RDS+EC2+security or DynamoDB+EC2+performance or EC2+EBS+Cost. Try to add more layer (i.e. CloudFront) and see how to address those five pillars concerns.
Thank you again LA team for the great service and thoughtful curriculm you created.
