Final answer:
The root of FQDN is on the far right, each domain can have subdomains, and DNS are organized into a tree-like structure. IANA registers domain names for Internet use.
Step-by-step explanation:
The correct answer is: None. All above are correct.
The first statement, "The root of FQDN is on the far right," is true. In a fully qualified domain name (FQDN), the root domain is located at the far right, followed by the top-level domain (TLD) and the subdomains.
The second statement, "Each domain can have subdomains," is also true. Domains can be divided into subdomains, allowing for further organization and delegation of authority.
The third statement, "DNS are organized into a tree-like structure," is true as well. The Domain Name System (DNS) is structured as a hierarchical tree, with the root domain at the top and branches of subdomains below.
Finally, the fourth statement, "IANA registers domain names for Internet use," is also true. The Internet Assigned Numbers Authority (IANA) manages the assignment of domain names and other resources for the Internet.
