Which of the following are two types of domain names?

The correct choice highlights two fundamental concepts in networking—relative names and fully qualified domain names (FQDN).

A relative name typically refers to a domain name that is not complete in terms of its hierarchy and context within the domain system. It is often used within the environment of a specific context, meaning it relies on the existing domain structure to be understood fully. For example, if you are accessing a website within a specified domain environment, you might only need to use a relative name to indicate that host.

In contrast, a fully qualified domain name (FQDN) is the complete address that specifies a particular server or host within the entire hierarchy of the Domain Name System (DNS). It includes the complete path from the root domain down to the specific host, ensuring that it can be resolved in the broader internet infrastructure without ambiguity. An example of an FQDN is "www.example.com," which clearly indicates both the specific host and the domain it belongs to.

Understanding these types of domain names is crucial for navigating and configuring networking environments effectively, particularly in tasks such as domain resolution and server configuration, where clarity about the exact address is essential.
