Explain what a hosted zone is and the difference between public and private hosted zones in AWS Route 53.

Think about where the DNS information is used and who can see it.

Describe the role of DNS records inside a hosted zone and why you cannot have multiple hosted zones for the same domain.

Consider how DNS resolution works and the importance of unique routing information.
