Question
In AWS, for VPC NACL (Network Access Control List) rules, Amazon recommends creating rule number by increments of [...] <-- bonus: think of why they recommend this
Answer

100

^^ They recommend this so you can easily add rules with proper order of precidence. For ex is you have a rule 100 that allows all incoming http (port 80) traffic (0.0.0.0/0), but then you want to add a rule to deny traffic from a specific IP, you would add the deny rule as rule 99 so it takes precedence over rule 100. If you had the Allow rule as rule 1, there was no where to fit your specific Deny rule.
