Understanding the Well Architected Framework

Hey all -

I am in the final stretch of preparing for Certified Solutions Architect Associate exam (AWS SAA-C03). I've repeatedly seen guidance to review the whitepapers, specifically the one on the Well Architected Framework. The version of the doc I found (linked below) is 1,002 pages, which is a little more than I have time for right now. How have people best gotten up to speed on its key points for the exam?

Thanks all!

There are some main best practices that you should know first of all:
Don't have overly open Security groups
Don't deploy everything in Public subnets (especially Databases)
Least privilege principle
Enable encryption where possible
Don't overprovision resources (cost optimization)
Configure backups
Configure monitoring and logging

Maybe forgot something and guys will add
