Trick to keep in mind+3 XP
Public or private? Follow the route table, not the IP range.
A subnet's label comes from where its route table sends traffic bound for the internet. A route to an internet gateway makes it public; without one it stays private. Neither a particular address range nor a permissive firewall rule changes that. When you want to know whether a subnet is public, open its route table.
Read it once, then a question tests whether the trick stuck.
