Maybe on Exam:
Availability zones are in geographically isolated data centers
IAM users are NOT defined on a per-region basis
If you are getting a permission error exception when trying to SSH into your linux instance, then the key is missing chmod 400 permissions

Security groups reference IP address, CIDR block, Security group, but NOT DNS name
