A big "Thank you" to LinuxAcademy team, I passed the CSA the last friday. I had a failed test 3 years ago, at that time the test looked more complicated compared to this new release.
Here my contribution with the new release: there were 3 topics that had more than 1 question per topics: DynamoDB, Redshift and Encryption. Explore a bit more Dynamo DB functionality, do't stay with only provisioning tables. With Redshift try to figure out how you will copy it to another region for DR purpose and with encryption understand what will happens if you can't store the keys in AWS. There were not questions about the Well Architect Framework.
My advice: I did first the Sysops training, then Solution Architect. The practice that that I got in Sysops helped to understand better some areas in the Solution Architect course. Finally, I bought the AWS Sysops official study guide from Amazon, i'm from old school and need to have my own books ! ;)
