 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
  • If you are getting a network timeout when trying to SSH into your EC2 instance, then your security groups are misconfigured
  • Security groups reference IP address, CIDR block, Security group, but NOT DNS name
