Which term describes the last part of a domain name, such as com, net, gov?

• A. Top-Level Domain (TDL)
• B. Topology
• C. Time-to-Live (TTL)
• D. Token

Answer: (A)

The last part of a domain name is the Top-Level Domain, the highest level in the domain name system. It appears to the far right of the name, and examples include com, net, gov. This suffix indicates the broader category or country and helps route DNS queries to the correct registries. DNS names are organized in a hierarchy: root, then the top-level domain, then second-level domains, and so on. The other terms don’t describe this part of a domain: topology is about how networks are interconnected, TTL is the time a DNS record is cached, and a token is unrelated to domain naming.
