Which term is primarily responsible for providing domain name resolution?

• A. Domain Name System (DNS)
• B. CSCS
• C. Cyber Command and Control Mission System (C3MS)
• D. Network Management Operator (NMO)

Answer: (A)

Domain name resolution is handled by the Domain Name System. When a device needs to reach a domain like example.mil, it asks a DNS resolver to translate that human-friendly name into an IP address the network can route to. DNS is a distributed, hierarchical system that starts with recursive resolvers, which query root servers, then the appropriate top-level domain servers, and finally the authoritative servers for the specific domain to obtain the exact IP. The result is cached to speed up future lookups. This mechanism is what makes web addresses, email destinations, and other services reachable by name rather than by numeric addresses. The other options describe different network or mission-system roles and do not provide the function of translating domain names to IP addresses.
